Japan — Rules of Origin & FTAs

Japan applies non-preferential rules of origin to determine the country of origin for purposes other than granting preferential tariff treatment under an Economic Partnership Agreement (EPA) or the Generalized System of Preferences (GSP). Non-preferential origin determinations are required for the application of WTO (most-favored-nation) tariff rates, anti-dumping duties, safeguard measures, trade statistics, and country-of-origin marking under Article 71 of the Customs Act.

## Statutory basis

Non-preferential rules of origin are codified in the Cabinet Order for the Enforcement of the Customs Act (関税法施行令, Kanzei-hō Sekō-rei) and the Finance Ministry Ordinance for the Enforcement of the Customs Act (関税法施行規則, Kanzei-hō Sekō Kisoku). These domestic regulations implement Japan's obligations under the WTO Agreement on Rules of Origin, which requires WTO members to apply transparent and predictable non-preferential origin rules.

The Customs Act itself (Act No. 61 of 1954, as amended) does not define origin criteria in detail; Article 68 of the Act requires importers to declare the country of origin in the import (customs duty payment) declaration, and the subordinate Cabinet Order and Ministry of Finance Ordinance supply the operative tests.

## Two-tier origin criteria

Under the Finance Ministry Ordinance for the Enforcement of the Customs Act, the country of origin of imported goods is determined by one of two criteria:

1. Wholly obtained goods

Goods wholly obtained or produced in a single country or area are originating in that country. The definition of "wholly obtained" is provided in the Finance Ministry Ordinance and is substantially the same as the wholly obtained definition used in Japan's EPAs and GSP scheme. It includes:

• goods harvested, extracted, or gathered in that country (minerals, plants, live animals born and raised there);
• marine products taken from the territorial sea or exclusive economic zone of that country;
• goods manufactured in that country exclusively from goods falling within the categories above.

2. Goods undergoing substantial transformation

When production involves materials from more than one country, the country of origin is the country where the goods last underwent a manufacturing or processing operation that qualifies as substantial transformation, as defined in the Finance Ministry Ordinance for the Enforcement of the Customs Act.

Substantial transformation is assessed by reference to:

• change in tariff classification at the chapter (two-digit), heading (four-digit), or subheading (six-digit) level of the Harmonized System, depending on the product; or
• specific manufacturing or processing operations prescribed for particular goods.

Japan Customs does not publish a single consolidated table of product-specific substantial-transformation rules for non-preferential purposes in the manner that it does for EPAs. Importers and exporters may request an advance ruling on origin under the procedures set out on the Japan Customs website to obtain a binding written determination, valid for three years, on whether a particular manufacturing process confers Japanese (or foreign) origin under the non-preferential framework.

## Procedural requirements

For non-preferential origin determinations, Japan Customs does not require submission of a certificate of origin or other formal proof-of-origin document at the time of import declaration. The country of origin is confirmed by the commercial invoice or other related import documents (such as bills of lading, packing lists, or supplier declarations). Customs retains the authority to request additional documentation or verification if the declared origin is in doubt, but the default procedure is documentary review rather than third-party certification.

This stands in contrast to preferential origin claims under EPAs or GSP, which require submission of a certificate of origin issued by the competent authority of the exporting country, an origin certification document completed by the importer/exporter/producer, or (under certain newer EPAs such as the Japan-EU EPA and Japan-UK EPA) a statement on origin made out by the exporter on a commercial document.

## Advance rulings and transparency

Japan Customs discloses advance rulings on origin that have been issued in writing, to enhance transparency and predictability for importers. The disclosed rulings are available (in Japanese) on the Japan Customs website. Importers and other related parties may submit a written request for an advance ruling on the origin of a good prior to importation using Customs Form C-1000-2. The ruling is valid for three years and is respected by Customs at the time of import declaration if a copy of the written ruling is submitted, provided the actual imported good matches the description in the ruling, the ruling has not expired, applicable laws have not been amended, and there was no error in the application of law.

Oral or email inquiries are also accepted but are provided for reference only and do not bind Japan Customs.

Japan has negotiated and brought into force Economic Partnership Agreements (EPAs) with over twenty countries and regions, including bilateral EPAs with Singapore, Mexico, Malaysia, Chile, Thailand, Indonesia, Brunei, the Philippines, Switzerland, Viet Nam, India, Peru, Australia, Mongolia, the European Union, and the United Kingdom, as well as plurilateral agreements including the ASEAN-Japan Comprehensive Economic Partnership Agreement (AJCEP), the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP or TPP11), and the Regional Comprehensive Economic Partnership (RCEP). These agreements provide for preferential tariff treatment (reduced or eliminated customs duties) for goods that qualify as originating under the rules of origin set out in each EPA.

Under the Customs Act, the provisions on rules of origin in each EPA are directly applied, and importers claiming preferential tariff treatment must submit documentary evidence of origin to Japan Customs at the time of import declaration. Japan's EPAs employ three distinct origin certification systems, and the applicable system varies by agreement.

## 1. Third-party certification system

Under the third-party certification system, the exporter applies for a certificate of origin (CO) to the CO-issuing authority of the exporting country and sends the CO to the importer. The importer makes the claim for preferential tariff treatment by submitting the CO issued by the competent authority of the exporting country at the time of import declaration.

All of Japan's EPAs, as well as the Generalized System of Preferences (GSP), apply this system. The list of competent authorities authorized to issue certificates of origin for each EPA is published on the Japan Customs Rules of Origin portal.

The certificate of origin must fulfill the format and data-element requirements set out in the respective EPA. Certificates of origin are valid for twelve months from the date of issuance and must be submitted to Japan Customs at the time of import declaration (except for consignments whose aggregate customs value does not exceed 200,000 yen, discussed below).

When using the third-party certification system, the only additional document required beyond the standard import declaration documents is the certificate of origin itself; Japan Customs does not require submission of additional explanations or materials beyond the CO, though importers remain responsible for verifying that the goods are originating goods.

Applicable EPAs under the third-party certification system include: Japan-Singapore, Japan-Mexico, Japan-Malaysia, Japan-Chile, Japan-Thailand, Japan-Indonesia, Japan-Brunei, Japan-ASEAN, Japan-Philippines, Japan-Switzerland, Japan-Viet Nam, Japan-India, Japan-Peru, Japan-Australia, and Japan-Mongolia.

## 2. Self-certification system (importer, exporter, or producer)

Under the self-certification system, the importer declares that the goods are originating goods by submitting an origin certification document completed by either the importer, exporter, or producer of the goods. No third-party governmental issuing authority is required.

This system was first introduced under the Japan-Australia EPA alongside the third-party certification system and is now also available under the CPTPP (TPP11), the Japan-EU EPA, the Japan-UK EPA (Comprehensive Economic Partnership Agreement), the Trade Agreement between Japan and the United States, and the RCEP Agreement.

The origin certification document may be prepared in any format, provided that it contains the minimum information requirements (data elements) stipulated in the relevant EPA annex. The document is valid for one year from the date of completion.

When claiming preferential tariff treatment under the self-certification system, the importer generally must also submit an explanatory sheet (or "attachment") describing the originating status of the good, including the production process, materials used, and how the applicable rule of origin is satisfied. This requirement is codified in Article 68 of the Customs Act and paragraphs 68-5-0 to 68-5-23 of the Basic Notice of the Customs Act.

Japan Customs may waive submission of the explanatory sheet when:

• the importer is claiming the waiver under the 200,000-yen de minimis rule (see below);
• a relevant advance ruling on origin has been obtained in writing and the advance ruling registry number is listed on the import declaration form; or
• wholly obtained or produced good status can be ascertained from invoices and other standard commercial documents (in which case the importer writes "EPA WO" on the import declaration form).

Under RCEP, the importer self-certification (self-declaration) system can only be used in relation to imports into Japan (not for Japanese exports to RCEP partners), whereas the exporter self-certification and third-party certification systems are available bidirectionally.

## 3. Approved exporter self-certification system

Under the approved exporter self-certification system, the importer presents the origin of the good by submitting an origin declaration made by an approved exporter on an invoice or other commercial document. The exporting country certifies their exporters as eligible to make an origin declaration and informs Japan of the approved exporters.

This system is applied under the Japan-Switzerland EPA, the Japan-Peru EPA, and the Japan-Mexico EPA, alongside the third-party certification system.

The prescribed text to appear in the origin declaration is set out in the respective EPA. The origin declaration is valid for one year from the date it is made.

## Documentary requirements and timing

In principle, the certificate of origin, origin declaration, or origin certification document must be submitted to Customs at the time of import declaration. However, Japan Customs may allow for postponement of the submission if there is an unavoidable reason for delay, such as a natural disaster, or when the importer has obtained advance approval for a "before-permit release" (importation before payment system, or BP).

For a consignment whose aggregate customs value does not exceed 200,000 yen, importers are not required to submit the certificate of origin, origin declaration, or origin certification document when claiming preferential tariff treatment under an EPA. This de minimis waiver is codified in Article 61 of the Cabinet Order for Enforcement of the Customs Act and paragraph 3-1 of the Basic Notice of Treaties and Agreements.

## Consignment criteria (direct shipment)

To be eligible for preferential tariff treatment under an EPA, the goods must also satisfy the consignment criteria (or direct-shipment requirement). Goods must be transported directly from the exporting country to Japan. When goods are transported through the territory of a third country for the purpose of transit or temporary storage, the importer must submit a document such as a through bill of lading (B/L) or a certificate of non-manipulation issued by the customs authority of the third country to prove that the goods did not undergo additional manipulation and that the consignment criteria of the EPA are satisfied.

## Statutory basis

The requirements for claiming preferential tariff treatment under EPAs are codified in Article 68 of the Customs Act (Act No. 61 of 1954, as amended), paragraphs 1 and 4 through 8 of Article 61 of the Cabinet Order for Enforcement of the Customs Act, paragraphs 68-5-0 to 68-5-23 of the Basic Notice of the Customs Act, and paragraphs 3-1 through 3-20 of the Basic Notice of Treaties and Agreements. Each EPA's rules of origin and certification requirements are directly incorporated by reference into Japanese customs law.

Under the Regional Comprehensive Economic Partnership (RCEP) Agreement, which entered into force for Japan on 1 January 2022, goods may qualify for preferential tariff treatment if they meet one of three origin criteria set out in Article 3.2 of Chapter 3 of the Agreement: (a) wholly obtained or produced goods; (b) goods produced exclusively from originating materials; or (c) goods that satisfy the applicable product-specific rule (PSR) set out in Annex 3A to Chapter 3.

Most goods that contain non-originating materials qualify under criterion (c) — the product-specific rule. Japan Customs publishes guidance explaining how to apply RCEP PSRs when claiming preferential tariff treatment for imports into Japan.

## Structure of Annex 3A product-specific rules

Annex 3A to Chapter 3 of the RCEP Agreement sets out product-specific rules organized by Harmonized System (HS) Code at the six-digit subheading level. Each PSR specifies the minimum transformation required for a good produced with non-originating materials to acquire originating status. The PSRs are applied to the HS Code of the finished good being imported, not to the materials used in production.

RCEP PSRs employ three types of criteria, which may appear singly or in the alternative (joined by "or"):

1. Change in tariff classification (CTC)

A change in tariff classification requires that all non-originating materials used in the production of the good have undergone a specified degree of tariff shift. RCEP uses three levels of tariff shift, identified by abbreviation:

• CC (Change in Chapter): all non-originating materials must be classified in a different two-digit HS chapter from the finished good.
• CTH (Change in Tariff Heading): all non-originating materials must be classified in a different four-digit HS heading from the finished good.
• CTSH (Change in Tariff Subheading): all non-originating materials must be classified in a different six-digit HS subheading from the finished good.

When a PSR specifies a change in tariff classification, the importer must identify the HS classification of all non-originating materials and confirm that each material differs from the finished good at the required level (chapter, heading, or subheading). Japan Customs guidance emphasizes that demonstrating a CTC rule does not always require the identification of the full six-digit subheading of every material; for example, if the PSR is "CC," the importer need only confirm that a non-originating material is classified outside the two-digit chapter of the finished good and need not identify the precise four-digit heading or six-digit subheading of the material.

Some CTC rules are qualified by additional requirements or exceptions. For instance, a PSR may read "CTSH, except from Subheading 2905.31," meaning that the change-in-subheading rule does not confer origin if a non-originating material is classified in Subheading 2905.31. In such cases, the importer must verify that no non-originating materials fall within the excepted subheading.

2. Regional value content (RVC)

A regional value content rule requires that the value of originating materials (or, equivalently, the value added within the RCEP region) meet a specified percentage threshold. RCEP RVC rules are expressed as "RVC40" or "RVC45," denoting a 40 per cent or 45 per cent regional value content requirement.

The formula for calculating RVC under the RCEP Agreement is set out in Article 3.5 of Chapter 3. The build-down method is:

RVC = [(FOB – VNM) / FOB] × 100

where:

• FOB is the free-on-board value of the good (the customs value under the WTO Valuation Agreement, adjusted to an FOB basis);
• VNM is the value of non-originating materials used in production.

Alternatively, the build-up method may be used:

RVC = [VOM / FOB] × 100

where VOM is the value of originating materials.

When a PSR specifies "CTSH or RVC40," the good qualifies if it satisfies either the change-in-subheading requirement or the 40 per cent regional value content threshold. The importer may select the method that requires the lesser burden of proof.

3. Specific process rules (SP)

Some PSRs require the performance of a specific manufacturing or processing operation rather than (or in addition to) a tariff shift or value-content threshold. These rules are product-specific and may include chemical-reaction tests, weight-percentage requirements for particular inputs, or operations such as spinning, weaving, dyeing, or assembly. Specific process rules are less common in RCEP than CTC and RVC rules but appear for certain textile, chemical, and food products.

## De minimis (tolerance) rule

Article 3.7 of Chapter 3 of the RCEP Agreement provides a de minimis rule that allows a good to qualify as originating even if certain non-originating materials fail to satisfy the applicable CTC requirement, provided the value or weight of those materials is insignificant.

The de minimis thresholds are:

• For goods classified in HS Chapters 1 to 97 (except Chapters 50 to 63): the value of non-originating materials that did not undergo the required change in tariff classification must not exceed 10 per cent of the FOB value of the finished good.
• For goods classified in HS Chapters 50 to 63 (textiles and apparel): the weight of non-originating materials that did not undergo the required change in tariff classification must not exceed 10 per cent of the total weight of the finished good. Alternatively, importers may elect to apply the 10 per cent value test instead of the weight test for goods in Chapters 50 to 63.

The de minimis rule does not apply to PSRs that are based solely on regional value content (RVC), nor does it waive the requirement that the finished good be produced entirely in a Party.

## Cumulation

Article 3.4 of Chapter 3 provides for cumulation of origin. Goods and materials that comply with the origin requirements of Article 3.2 and are used in another RCEP Party as materials in the production of another good are considered originating in the Party where working or processing of the finished good has taken place. This means that an originating material produced in RCEP Party A and then incorporated into a good in RCEP Party B is treated as if it were an originating material of Party B, allowing the value or status of the material to count toward the origin determination of the finished good.

As of the date of entry into force of the RCEP Agreement, cumulation is limited to originating materials (diagonal cumulation). The Agreement contemplates a future review to consider extending cumulation to non-originating materials (full cumulation), but that review has not yet resulted in an amendment.

## Minimal operations and processes

Article 3.6 of Chapter 3 and Article 2.6.5 of Chapter 2 of the RCEP Agreement specify that certain minimal operations or processes do not confer origin even if the applicable PSR is satisfied. Minimal operations include simple packaging, labeling, sorting, washing, cutting to length or size, dilution, and assembly of parts when the assembly does not involve substantial transformation. A good that has undergone only minimal operations in a Party is not considered an originating good, irrespective of whether it meets the technical requirements of the PSR.

## Procedure for applying product-specific rules

When claiming preferential tariff treatment for an import into Japan under RCEP, the importer must:

1. Identify the six-digit HS subheading of the finished good using Japan's tariff schedule.
2. Look up the applicable PSR in Annex 3A to Chapter 3 of the RCEP Agreement (the full text of Annex 3A is linked from the Japan Customs RCEP portal).
3. Determine whether the good satisfies the PSR by applying the CTC, RVC, or specific process test specified in the rule. Japan Customs guidance provides worked examples showing how to apply CTC rules (e.g., pickles classified in Subheading 2001.90 with a PSR of "CC") and RVC rules (e.g., propylene glycol classified in Subheading 2905.32 with a PSR of "CTSH or RVC40").
4. Consider alternative pathways to origin if the good fails the PSR on its face: cumulation (if originating materials from other RCEP Parties were used), de minimis (if the value or weight of non-compliant materials is below the 10 per cent threshold), or classification as a good produced exclusively from originating materials under Article 3.2(b).

Japan Customs emphasizes that selecting the method that requires the lesser burden of proof is advisable when multiple pathways to origin are available. For example, demonstrating that a good satisfies a PSR under Article 3.2(c) often requires less documentation than proving that all materials used in the final stage of production are originating goods under Article 3.2(b).

## Statutory basis and amendment procedure

The product-specific rules set out in Annex 3A are directly incorporated into Japanese customs law as part of the RCEP Agreement. Article 3.34 of Chapter 3 provides that the RCEP Joint Committee may amend or transpose the PSRs to reflect updates to the Harmonized System nomenclature. Any transposed PSRs adopted by the Joint Committee are published by Japan Customs on the RCEP portal and apply automatically to import declarations filed after the effective date of the amendment.

Japan has concluded Economic Partnership Agreements (EPAs) with multiple countries and regional economic blocs, covering both bilateral and plurilateral frameworks. These agreements establish preferential tariff treatment for qualifying originating goods and, in most cases, include chapters on services trade, investment protection, intellectual property, government procurement, and regulatory cooperation.

Japan's EPA network includes two major plurilateral agreements — the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the Regional Comprehensive Economic Partnership (RCEP) Agreement — as well as bilateral EPAs with key trading partners across Asia, Oceania, the Americas, and Europe.

## Plurilateral Economic Partnership Agreements

Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP)

The CPTPP was signed on 8 March 2018 by eleven countries and entered into force for Japan on 30 December 2018. The CPTPP is the successor to the Trans-Pacific Partnership (TPP) Agreement signed in February 2016, which did not enter into force following the withdrawal of the United States in January 2017.

Original CPTPP signatories (March 2018): Australia, Brunei Darussalam, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, and Viet Nam. United Kingdom accession: The UK acceded to the CPTPP, with the agreement entering into force for the United Kingdom on 15 December 2024.

The CPTPP includes comprehensive rules of origin set out in Chapter 3, with product-specific rules in Annex 3-D. The agreement applies a self-certification system for origin.

Regional Comprehensive Economic Partnership (RCEP) Agreement

The RCEP Agreement was signed on 15 November 2020 and entered into force for Japan on 1 January 2022. As of June 2026, the RCEP Agreement has entered into force for Japan, Australia, Brunei Darussalam, Cambodia, China, Indonesia, Republic of Korea, Lao PDR, Malaysia, New Zealand, the Philippines, Singapore, Thailand, and Viet Nam. Myanmar has not yet ratified the agreement.

The RCEP includes rules of origin set out in Chapter 3. The agreement supports both third-party and self-certification.

## Bilateral Economic Partnership Agreements — Asia-Pacific

Japan has bilateral EPAs with: Singapore (in force 30 November 2002), Mexico (1 April 2005, revised protocol 1 April 2012), Malaysia (13 July 2006), Chile (3 September 2007), Thailand (1 November 2007), Indonesia (1 July 2008), Brunei Darussalam (31 July 2008), Philippines (11 December 2008), Viet Nam (1 October 2009), India (1 August 2011), Peru (1 March 2012), Australia (15 January 2015), Mongolia (7 June 2016), and Bangladesh (signed February 2026; entry into force TBA). The ASEAN–Japan Comprehensive Economic Partnership Agreement (AJCEP) entered into force for Japan on 1 December 2008; its First Protocol entered into force for Japan on 1 August 2020.

Where entry-into-force dates were not directly available in official treaty or diplomatic-note publications, dates are drawn from Ministry of Foreign Affairs (MOFA) Bluebook materials and Japan Customs summaries and are so qualified; for legislative authority, consult the applicable agreement text or Customs notification.

## Bilateral Economic Partnership Agreements — Europe

• Japan–Switzerland EPA: in force 1 September 2009, first to introduce the approved-exporter self-certification system.
• Japan–EU EPA: in force 1 February 2019. Protocol on free flow of data entered into force on 1 July 2024 (per EU Digital Strategy communication).
• Japan–UK Comprehensive Economic Partnership Agreement (CEPA): in force 1 January 2021.

## Japan–United States Trade Agreement

The Trade Agreement between Japan and the United States of America and the Japan–US Digital Trade Agreement entered into force on 1 January 2020. A protocol amending the Trade Agreement to modify agricultural safeguards for U.S. beef entered into force on 1 January 2023. The Japan–US agreements are not comprehensive EPAs and do not include rules of origin chapters. For goods covered, preferential treatment is claimed by declaring the country of origin and regular documentation; no certificate of origin is required.

## EPAs under negotiation

As of June 2026, MOFA lists the following as under negotiation/study: Japan–Colombia EPA (negotiations launched December 2012; status as of June 2026 not confirmed); Japan–China–Republic of Korea FTA (negotiations launched March 2013; sixteen rounds by December 2021); Japan–GCC (Gulf Cooperation Council) EPA, Japan–Canada EPA, Japan–Bangladesh EPA (now signed), Japan–Türkiye EPA, Japan–UAE EPA, and Japan–Republic of Korea EPA (negotiation statuses as of June 2026 not confirmed by primary announcement).

## Statutory framework and tariff schedule

Japan's EPA preferential tariff rates are codified in the Customs Tariff Act (Act No. 54 of 1910, as amended) and the Cabinet Order for Enforcement of the Customs Tariff Act. The Japan Customs Tariff Schedule is managed by the Customs and Tariff Bureau and is available via the Japan Customs website. The requirements for preference claims are set out in Article 68 of the Customs Act, the relevant Cabinet Orders, and Basic Notice of the Customs Act.

## Overlapping EPA eligibility

Where more than one EPA is available, the importer may elect which EPA to claim, provided statutory and procedural conditions for preference are satisfied (see Japan Customs EPA portal guidance).

Material corrections in this update:

Under the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP or TPP11), which entered into force for Japan on 30 December 2018, goods may qualify for preferential tariff treatment if they meet one of three origin criteria set out in Article 3.2 of Chapter 3 of the Agreement: (a) wholly obtained or produced goods; (b) goods produced exclusively from originating materials; or (c) goods that satisfy the applicable product-specific rule (PSR) set out in Annex 3-D to Chapter 3.

Most goods that contain non-originating materials qualify under criterion (c) — the product-specific rule. Japan Customs publishes guidance explaining how to apply CPTPP PSRs when claiming preferential tariff treatment for imports into Japan.

## Structure of Annex 3-D product-specific rules

Annex 3-D to Chapter 3 of the CPTPP sets out product-specific rules organized by Harmonized System (HS) Code at the six-digit subheading level. Each PSR specifies the minimum transformation required for a good produced with non-originating materials to acquire originating status. The PSRs are applied to the HS Code of the finished good being imported, not to the materials used in production.

CPTPP PSRs employ three primary types of criteria, which may appear singly or in the alternative (joined by "or") or in combination (joined by "and"):

1. Change in tariff classification (CTC)

A change in tariff classification requires that all non-originating materials used in the production of the good have undergone a specified degree of tariff shift. CPTPP uses four levels of tariff shift, identified by abbreviation:

• CC (Change in Chapter): all non-originating materials must be classified in a different two-digit HS chapter from the finished good.
• CTH (Change in Tariff Heading): all non-originating materials must be classified in a different four-digit HS heading from the finished good.
• CTSH (Change in Tariff Subheading): all non-originating materials must be classified in a different six-digit HS subheading from the finished good.
• CR (Change to a specific subheading or heading from any other heading or chapter): the finished good must be classified in the specified heading or subheading, and all non-originating materials must come from outside that heading or chapter, as specified in the rule.

Some CTC rules are qualified by additional requirements or exceptions. For example, a PSR may read "CTSH, except from subheading X," meaning that the change-in-subheading rule does not confer origin if a non-originating material is classified in subheading X. In such cases, the importer must verify that no non-originating materials fall within the excepted subheading or heading.

2. Regional value content (RVC)

A regional value content rule requires that the value of originating materials (or, equivalently, the value added within the CPTPP region) meet a specified percentage threshold. CPTPP RVC rules are typically expressed as percentages ranging from 30 per cent to 65 per cent, depending on the product.

The formulas for calculating RVC under the CPTPP are set out in Article 3.5 of Chapter 3. The Agreement permits three calculation methods, and importers may select the method that is most favorable:

Build-down method (transaction value):

RVC = [(AV – VNM) / AV] × 100

where:

• AV is the adjusted value of the good (the transaction value of the good adjusted to an FOB basis);
• VNM is the value of non-originating materials, including freight, insurance, packing, and all other costs incurred in transporting the material to the location of the producer.

Build-up method (transaction value):

RVC = [VOM / AV] × 100

where VOM is the value of originating materials.

Net cost method:

RVC = [(NC – VNM) / NC] × 100

where NC is the net cost of the good, calculated by deducting sales promotion, marketing, after-sales service costs, royalties, shipping and packing costs, and non-allowable interest costs from the total cost of the good.

The net cost method is mandatory for certain automotive goods specified in Annex 3-D and the automotive-specific Appendix 1 to Annex 3-D (provisions related to product-specific rules of origin for certain vehicles and parts of vehicles). For most other goods, importers may elect any of the three methods.

When a PSR specifies "CTSH or RVC 45," the good qualifies if it satisfies either the change-in-subheading requirement or the 45 per cent regional value content threshold. The importer may select the method that requires the lesser burden of proof or for which documentation is more readily available.

3. Specific process rules and wholly obtained criteria

Some PSRs require the performance of a specific manufacturing or processing operation rather than (or in addition to) a tariff shift or value-content threshold. These rules are product-specific and may include chemical-reaction tests (e.g., "a chemical reaction is undergone"), weight-percentage requirements for particular inputs, or operations such as spinning, weaving, dyeing, extrusion, or assembly accompanied by a specified level of value addition. Specific process rules appear for certain textile, chemical, steel, and automotive products.

For goods that are entirely obtained or produced in a single CPTPP Party without the incorporation of any materials from a non-Party, the wholly obtained criterion under Article 3.3 of Chapter 3 applies. The definition of wholly obtained is functionally equivalent across Japan's EPAs and includes goods harvested, extracted, or gathered in a Party (minerals, plants, live animals born and raised there), marine products taken from the territorial sea or exclusive economic zone of a Party or from the high seas by a vessel registered in and flying the flag of a Party, and goods manufactured in a Party exclusively from such materials.

## De minimis (tolerance) rule

Article 3.6 of Chapter 3 of the CPTPP provides a de minimis rule that allows a good to qualify as originating even if certain non-originating materials fail to satisfy the applicable CTC requirement, provided the value or weight of those materials is insignificant.

The de minimis thresholds are:

• For goods classified in HS Chapters 1 to 27 (agricultural and mineral products): the value of all non-originating materials that did not undergo the required change in tariff classification must not exceed 10 per cent of the transaction value or total cost of the finished good.
• For goods classified in HS Chapters 28 to 97 (industrial products): the value of all non-originating materials that did not undergo the required change in tariff classification must not exceed 10 per cent of the transaction value or total cost of the finished good.

For textile and apparel goods classified in HS Chapters 50 to 63, Chapter 4 (Textile and Apparel Goods) of the CPTPP sets separate de minimis rules: goods classified in Chapters 50 to 60 may contain up to 10 per cent by weight of non-originating fibres or yarns that do not undergo the required tariff shift, and goods classified in Chapters 61 to 63 may contain up to 10 per cent by weight of non-originating fibres or yarns in the component that determines the tariff classification of the finished good.

The de minimis rule does not apply when the PSR is based solely on a wholly obtained criterion or when the rule expressly states that the de minimis provision does not apply. Additionally, the good must still be produced entirely in one or more CPTPP Parties (the de minimis rule does not waive the requirement that the last production step occur in a Party).

## Accumulation (cumulation) of origin

Article 3.4 of Chapter 3 provides for accumulation of origin. A material that is an originating good under the rules of origin of Chapter 3 is treated as an originating material when it is used in the production of another good in the same or a different CPTPP Party. This means that an originating material produced in CPTPP Party A and then incorporated into a finished good in CPTPP Party B is treated as if it were an originating material of Party B, allowing the value or status of the material to count toward the origin determination of the finished good.

CPTPP cumulation applies to originating materials (diagonal cumulation). A non-originating material used in Party A to produce an originating intermediate good, and that intermediate good then shipped to Party B for further production, allows the intermediate good to be treated as originating in the cumulation calculation, but the underlying non-originating material does not itself become originating.

Importers relying on cumulation must confirm that the intermediate material qualifies as originating under the CPTPP rules of origin (either by obtaining a statement from the supplier of the intermediate material or by applying the relevant PSR to the intermediate good).

## Minimal operations and processes

Article 3.8 of Chapter 3 specifies that certain minimal operations or processes do not confer origin even if the applicable PSR is technically satisfied. Operations that are considered insufficient to confer origin include:

• operations to ensure the preservation of goods in good condition during transport and storage (ventilation, spreading, drying, chilling, placing in salt or other aqueous solutions, removal of damaged parts);
• simple operations consisting of removal of dust, sifting or screening, sorting, classifying, washing, painting, or cutting;
• changes of packaging and breaking up and assembly of packages;
• simple cutting, slitting, or repackaging or placing in bottles, cases, or boxes;
• affixing marks, labels, or other distinguishing signs on products or their packaging;
• simple mixing of goods (whether or not of different kinds) where one or more components of the mixture do not meet the applicable origin requirements;
• simple assembly of parts to constitute a complete good; or
• slaughter of animals.

A good that has undergone only minimal operations in a Party is not considered an originating good, irrespective of whether it meets the technical requirements of the PSR set out in Annex 3-D. Japan Customs guidance emphasizes that assembly operations must be accompanied by substantial value addition or a required tariff shift beyond simple joining of parts to confer origin.

## Procedure for applying product-specific rules when claiming preferential tariff treatment

When claiming preferential tariff treatment for an import into Japan under the CPTPP, the importer (or the exporter or producer completing an origin certification document on behalf of the importer) must:

1. Identify the six-digit HS subheading of the finished good using Japan's tariff schedule.
2. Look up the applicable PSR in Annex 3-D to Chapter 3 of the CPTPP (the full text of Annex 3-D is published on the Cabinet Office TPP website and linked from the Japan Customs CPTPP portal).
3. Determine whether the good satisfies the PSR by applying the CTC, RVC, or specific process test specified in the rule. If the PSR offers alternative pathways (e.g., "CTSH or RVC 45"), the importer may elect the pathway that is most readily demonstrated with available documentation.
4. Consider cumulation and de minimis if the good fails the PSR on its face. If originating materials from other CPTPP Parties were used, cumulation may allow those materials to be treated as originating in the country of production. If a small quantity of non-originating materials failed the tariff-shift test but the value or weight is within the 10 per cent de minimis threshold, the good may still qualify.
5. Prepare the origin certification document (or request a certificate of origin from the competent authority of the exporting Party, depending on the certification system being used). The CPTPP applies a self-certification system under which the importer, exporter, or producer may complete an origin certification document; no third-party governmental issuance is required. The data elements for the certification of origin are set out in Article 3.20 of Chapter 3. Japan Customs requires importers using the self-certification system to submit an attachment sheet (explanatory document) describing the production process, materials used, and how the applicable PSR is satisfied, except when claiming the 200,000-yen de minimis waiver or when an advance ruling on origin has been obtained.

Japan Customs provides worked examples of PSR application in the Guideline on 'Self-Certification System' (CPTPP edition) published on the Japan Customs Rules of Origin portal.

## Statutory basis and amendment procedure

The product-specific rules set out in Annex 3-D are directly incorporated into Japanese customs law as part of the CPTPP. Article 3.27 of Chapter 3 provides that the CPTPP Commission may modify Annex 3-D to reflect updates to the Harmonized System nomenclature or to amend the PSRs. Any modifications adopted by the Commission are published by Japan Customs on the CPTPP portal and apply automatically to import declarations filed after the effective date of the modification.

The requirements for claiming preferential tariff treatment under the CPTPP are codified in Article 68 of the Customs Act (Act No. 61 of 1954, as amended), paragraphs 1 and 4 through 8 of Article 61 of the Cabinet Order for Enforcement of the Customs Act, paragraphs 68-5-0 to 68-5-23 of the Basic Notice of the Customs Act, and paragraphs 3-1 through 3-20 of the Basic Notice of Treaties and Agreements.

Japan Customs offers an advance ruling system for the origin of goods under both non-preferential and Economic Partnership Agreement (EPA) contexts. An advance ruling on origin provides legally binding confirmation from Customs on whether the production process of specified goods confers Japanese (or foreign) origin under the operative rules — crucial for import planning, risk management, and tariff treatment certainty. The ruling system is governed primarily by Article 7-4 of the Customs Act (関税法第7条の4) and detailed in related administrative guidance and forms.

Who can apply: Applications may be made by importers (or prospective importers), exporters, producers, or their agents. The applicant must be directly involved with the transaction or production in question.

Scope of ruling: Advance rulings are available for (a) the country of origin of a specific product (applied under Japan’s non-preferential rules or specified under an EPA); (b) tariff classification; (c) customs valuation; and (d) other matters set out in Ministry of Finance ordinance.

Process:

• The applicant submits a written request for an advance ruling using Customs Form C-1000-2 (裁決申請書), stating the precise nature of the good, its composition/production process, and the applicable legal rules of origin or EPA article(s). Sample forms in English and Japanese, along with application instructions, are published on the Japan Customs website.
• Supporting documentation should include product specs, process charts, supplier declarations, and draft statements of origin.
• Upon completion of the submission, Customs issues a receipt and commences a review. Additional information or clarifications may be requested.
• Japan Customs aims to issue a written ruling within a “reasonable period” — guidance documents note a general target of 90 days from receipt of a complete application, though this period may be extended if additional documents are required.

Legal effect and validity:

• The advance ruling is valid for three years from issuance unless (a) laws or administrative interpretations change, (b) the factual situation differs from the application, or (c) the ruling is withdrawn for good cause.
• Rulings are binding on Customs in relation to import declarations matching the facts described in the ruling as long as the ruling is current and law unamended; importers must submit a copy of the written ruling with their declaration.
• Rulings are not transferable—they apply only to the goods, parties, and production process described in the application.

Public disclosure:

• Non-confidential advance rulings on origin are published (in Japanese) on the Japan Customs website to ensure transparency and consistency in interpretation.
• Oral and email pre-consultations are permitted but are non-binding and for reference only.

Basis and sources: Rules codified under the Customs Act Art. 7-4; implementing procedure and forms at Japan Customs’ advance ruling portal.

Japan’s Economic Partnership Agreements (EPAs) provide three distinct mechanisms by which importers can prove origin: (1) third-party certificate of origin issued by the competent authority of the exporting country, (2) declaration of origin by an exporter approved by that authority ("approved exporter"), and (3) self-declaration by the importer, exporter, or producer. The specific regime depends on the EPA text; Japan Customs operationalizes these rules through Article 68 of the Customs Act, Cabinet Order Article 61, and implementing notices.

Third-Party Certificate of Origin — Under most early bilateral and plurilateral EPAs, including the ASEAN-Japan Comprehensive Economic Partnership (AJCEP), Japan–Singapore EPA, and others, a certificate of origin must be issued by a designated government authority or accredited body in the exporting country. The importer claims preferential treatment by submitting this certificate with the import declaration. The Customs FAQ confirms this is the general regime for the majority of Japan’s bilateral EPAs. Validity and documentation requirements are determined by the EPA language: for example, a 12-month validity window is typical, but specifics must be confirmed from the text of each EPA. The Japan Customs portal links lists of issuing authorities per EPA.

Approved Exporter Declaration — Some EPAs—such as those with Switzerland, Peru, and Mexico—allow exporters certified as "approved exporters" by their competent authority to declare origin on invoices instead of obtaining a separate certificate. Only exporters registered with the foreign authority may use this system, and declaration language/requirements are stipulated by the EPA’s annex. Japan Customs lists recognized approved exporters by EPA on its EPA portal. Details, including validity periods and procedural requirements, are determined in each agreement’s procedural annex.

Self-Declaration (Importer/Exporter/Producer) — In more recent agreements such as the Japan–EU EPA, Japan–UK CEPA, CPTPP, and RCEP, origin may be declared by the importer, exporter, or producer on a standard commercial document. This eliminates the need for an external certificate, but the declarant is liable for accuracy. Japan Customs generally requires submission of an explanatory or “attachment” sheet detailing how origin was determined. Specific exemptions (for instance, a value threshold such as 200,000 yen for simplified documentation) vary by agreement and are confirmed in the text of each EPA and Japan Customs Basic Notices.

Japan Customs’ portal provides an EPA-by-EPA table of which origin-certification systems are available for each arrangement. In some cases (e.g., Japan–Australia EPA) more than one system is permitted. The legal authority and much procedural detail are contained in Customs Act Article 68, Cabinet Order Article 61, and Basic Notice 68-5-0 to 68-5-23, as well as the procedural and annex sections of the relevant EPA; for any operational detail, consult the official EPA text or Japan Customs guidance for the agreement in question.

Japan’s Generalized System of Preferences (GSP) provides reduced or zero-duty tariff rates for qualifying imports originating from designated developing and least-developed countries (LDCs), outside the Economic Partnership Agreement (EPA) system. To obtain GSP benefits, importers must prove that goods (1) satisfy the origin criteria for GSP beneficiaries and (2) are supported by the proper documentary evidence, primarily the Certificate of Origin (Form A).

Origin criteria — Under Japan’s GSP, origin rules are set by the Customs Tariff Act and the Cabinet Order for its enforcement. Goods wholly obtained or produced in a GSP country (such as minerals, plants, or animals born in that country) qualify directly. For products made using imported materials, two tests generally apply: (a) the non-originating materials must undergo a change in tariff heading (four-digit HS code) due to processing in the beneficiary country, and (b) the value of non-originating materials must not exceed a percentage set by regulation, with a higher allowance for LDCs. As of June 2026, the precise value threshold percentages and detailed “substantial transformation” criteria are set out in Cabinet Order articles, but are not directly stated in the English-language FAQ or overview. Unable to confirm as of 2026-06-15 the exact percentages from primary English-language government sources.

Regional and diagonal cumulation — Japan’s GSP allows certain cumulation: inputs from countries within approved regional groups (e.g., ASEAN) may be considered as originating if further processed in the final exporting country, provided Cabinet Order conditions are met. The grouping and limitation details (which countries, what degree of processing) are specified in the regulation, but the full breakdown is not confirmed in available English-language government sources. Unable to confirm as of 2026-06-15 the exact group definitions or operational differences from EPA cumulation.

Certificate of Origin (Form A) — To claim GSP, importers must submit the official GSP Certificate of Origin (Form A), issued by the competent authority of the exporting country, at the time of import declaration. Electronic or self-certification is not permitted under the GSP system; submission of Form A is mandatory. The Ministry of Finance and Japan Customs FAQ confirms that post-clearance claims for GSP treatment are not accepted: if Form A is not submitted at import, GSP rates are denied. Guidance on completing and submitting Form A, and procedures for regional cumulation, is available in Japan Customs’ public materials, but may require consultation of the Japanese legal text or agency notification for special cases.

Under Japan's Economic Partnership Agreements (EPAs) and preferential origin regimes, certain operations are explicitly defined as "minimal operations" or "insufficient processing" that do NOT confer origin, regardless of whether other technical origin criteria (like tariff shift or value content) appear to be met. This rule exists to prevent simple manipulations (such as packaging, labeling, or sorting) from converting non-originating goods into originating ones.

## Statutory and treaty basis

Minimal operations are set out in the text of each EPA—see, for example, Article 3.6 of the Regional Comprehensive Economic Partnership (RCEP) Agreement, Article 3.8 of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), and Article 3.26 of the Japan-EU EPA. Japan's implementing rules require importers to take these minimal-processing exclusions into account for every preferential origin claim (Customs Act Article 68, Cabinet Order Article 61, relevant EPA articles and annexes).

## Typical minimal operations list

The following are typical examples that do NOT confer origin (the precise list may vary by EPA—always consult the relevant treaty annex):

• Simple packaging, bottling, placing in bags or boxes
• Sorting, grading, or classifying
• Affixing marks, labels, or other distinguishing signs
• Simple mixing not resulting in substantial transformation
• Washing, cleaning, removal of dust
• Simple assembly of parts (without significant value added)
• Preservation operations for transport/storage only
• Slaughter of animals

The precise list varies by EPA, but the intent is the same: origin is NOT conferred if the processing or work carried out in the country merely consists of one or more of these simple operations, unless combined with more substantial manufacturing or a process that itself satisfies the product-specific rule (PSR) in the EPA.

## Operational implications

If an importer claims origin under a Japan EPA and Japan Customs determines only minimal operations were performed, the claim will be denied—even if other documentation (certificate of origin, origin declaration, or explanatory sheet) is present. This tripwire most often affects trading companies and contract packagers, especially where primary manufacturing occurs outside Japan but final packing/labeling is done in Japan or an EPA partner.

Minimal processing exclusions are operationally significant under CPTPP, RCEP, the Japan-EU EPA, and Japan-UK CEPA. Each agreement contains an annex or list of "insufficient operations"—for instance, CPTPP Article 3.8 and Annex 3-D, RCEP Article 3.6 and Annex 3A, and Japan-EU EPA Article 3.26. Importers must check the relevant EPA for the explicit list and references.

## Best practices

• Always consult the EPA text and Japan Customs guidance for the specific minimal operations list.
• Where operations in Japan are borderline, seek an advance ruling on origin detailing the full manufacturing process.
• Documentation showing substantial manufacturing or transformation should be retained to establish origin conferral in the event of post-clearance audit.

Cumulation of origin (also called accumulation) allows materials or processing performed in another FTA or EPA (Economic Partnership Agreement) partner country to count as “originating” for the purpose of qualifying finished goods for preferential tariff rates in Japan. Cumulation is a cornerstone of regional supply-chain planning, and the detailed rules are set by each agreement.

## Treaty Authority and Key Types of Cumulation

• RCEP (Regional Comprehensive Economic Partnership), Article 3.4: RCEP allows diagonal cumulation among all Parties. If a Japanese manufacturer imports inputs that qualify as originating in an RCEP partner, those materials are treated as originating in Japan for purposes of Japan’s RCEP rules, so long as each input meets the Agreement’s origin criteria. Example: A component produced in Thailand using Korean-origin steel (both RCEP Parties), where both countries’ processing meets RCEP origin requirements, counts as originating for a finished product in Japan. The provision reads: “A Party may consider a good or material originating in another Party as originating in its territory when used in the production of a good.”

• CPTPP (Comprehensive and Progressive Agreement for Trans-Pacific Partnership), Article 3.4: Similar diagonal cumulation rules apply. Any material proven to be originating in a CPTPP country counts as originating anywhere else in the CPTPP region, provided supporting documentation is available. The text reads: “A Party shall provide that a good is originating if the good is produced in the territory of one or more of the Parties by one or more producers” using materials originating under CPTPP rules.

• Japan-EU EPA and Japan-UK CEPA (Article 3.5): Both apply diagonal cumulation as well—managers may aggregate qualifying processing or materials from any party to the agreement. E.g., goods finished in Japan incorporating Spanish-origin and UK-origin content may use both for origin claims, subject to the agreement’s PSR or regional value content (RVC) test.

• Bilateral Cumulation: Earlier agreements (e.g., Japan–Singapore EPA) restrict cumulation to inputs and processes from Japan and the specific partner only. Diagonal cumulation is not generally operative unless expressly stated in the agreement.

• Full Cumulation: Full cumulation—where value-added from any processing in Parties is aggregated even if not itself origin-conferring—is not generally available under Japanese EPAs/FTAs. Unable to confirm as of 2026-06-16 any full cumulation protocols operative for Japan.

## Operational Requirements

• For cumulation to apply, each input must qualify as originating under the agreement, proven with a certificate of origin, self-declaration, or other recognized evidence per the treaty and Japan Customs EPA portal guidance.
• The total value or processing carried out in the Parties is aggregated under the product-specific rule or RVC test. Documentation (invoice, origin statement) for each cumulated input must be retained for audit.
• Minimal operations (packaging, relabeling, etc.) remain excluded: even if performed in an EPA country, these do not confer origin or support cumulation. This exclusion is explicit in CPTPP Art. 3.8 and RCEP Art. 3.6, as echoed in Japan Customs guidance.

Summary: Cumulation is a potent origin-planning tool under Japan’s newer agreements (RCEP, CPTPP, EU/UK), but always check the precise EPA text for the actual scope and required evidence—older EPAs are often more limited. As of mid-2026, full cumulation is not a standard feature in the Japanese FTA network.

Japan Customs may verify the correctness of preferential origin claims both at the time of import declaration and after customs clearance, as specifically authorized by the Customs Act and supporting Cabinet Orders. This verification is fundamental to the operation of Economic Partnership Agreements (EPAs), the Generalized System of Preferences (GSP), and similar regimes, where duty reduction depends on documented origin status.

Verification Procedure and Scope At time of import, Japan Customs examines the documentary evidence required for a preferential claim—such as a certificate of origin, declaration by an approved exporter, or origin certification/explanatory sheet (when required under self-certification systems). Customs may clear the goods immediately or request additional documentation if any question arises. After clearance, Customs is authorized to conduct a post-import (post-entry) verification by requesting further evidence, including supplementary documents or explanations from the importer (Customs Act Art. 68; Outline of Rules of Origin, Japan Customs). These inquiries may be triggered by random selection or specific compliance risk, but the relevant sources indicate only that verification is routine and required for proper administration of origin regimes; they do not enumerate specific risk triggers or audit selection algorithms.

Importer's Retention and Production Duties Under Article 95 of the Customs Act, importers making an origin-based preferential claim are required to retain all documents related to that claim—including certificates, origin statements, supporting cost breakdowns, and any shipment or production records—for a period of five years from the date of import. If Japan Customs initiates a verification, the importer must produce these documents “without delay.” The sources confirm these duties as general EPA/GSP requirements, but do not differentiate in detail between systems unless specified in treaty or agency guidance.

Outcomes and Risks if Origin is Denied If Japan Customs determines via audit or document review that a claim for preferential origin was not actually valid, the authority may retroactively assess normal duties (instead of the preferential rate) on the import, along with applicable interest (Customs Act Arts. 6, 68). While the Act authorizes penalties for misrepresentation or false declaration (see Arts. 108 and 118), the English-language official sources are general on the type and size of penalties and do not explicitly detail when criminal sanctions or higher administrative penalties may apply. Importers should expect, at minimum, loss of preference, duty and interest reassessment, and potential administrative penalties if Customs finds insufficient evidence was kept or submitted as required.

The above rules are based on the Customs Act (Act No. 61 of 1954, as amended) and Japan Customs public guidance as current to 2026. EPA-specific verification protocols may contain additional requirements or steps, and importers are advised to review agreement text and official guidance for the relevant EPA.

The Japan–EU Economic Partnership Agreement (EPA)—in force since February 1, 2019—defines how products imported into Japan from the European Union can claim preferential tariff rates. Central to this process are the product-specific rules (PSRs) found in Annex 3-B and the unique “statement on origin” system, which eliminates the traditional government-issued certificate of origin in favor of a self-certified declaration by the exporter or importer.

Annex 3-B and How Origin is Conferred

Each product is assigned a PSR by six-digit Harmonized System (HS) code in Annex 3-B. Most goods can qualify as originating by one of three paths: (a) wholly obtained or produced in the EU; (b) produced exclusively from originating materials; or (c) by satisfying the PSR for that HS code. Representative PSR formats include:

• Change in tariff heading (CTH) or subheading (CTSH)—e.g., Chapter 84 industrial machinery (HS 8471, computers) generally requires a CTH for origin;
• Regional value content (RVC), typically 40% or 50%, e.g., some automotive (HS 8708) and textile (HS 61/62) products;
• Specific process requirements, such as certain chemical reactions for chemicals (HS 29) or listed textile processes.

PSRs can be offered as alternatives (“CTH or RVC 50%”) or in combination (“CTH and RVC 40%”), allowing the importer to select the rule that is most easily satisfied. The de minimis rule (Art. 3.7) permits a good still to qualify for preference if non-originating materials failing the CTC requirement make up no more than 10% of the ex-works price—subject to exclusions for certain sensitive products.

Statement on Origin: Documentation and Proof

Instead of a government-issued certificate, importers present a "statement on origin"—a specific declaration by an EU exporter registered in the EU’s REX system or by a Japanese importer with adequate records. The statement can be on a commercial invoice or similar document; its text and required data elements are set out in Annex 3-D. For shipments up to ¥200,000, the statement is not required, but importers must be able to demonstrate qualifying origin on request. This system streamlines border processing but places responsibility for accuracy on the declarant. Supporting evidence (supplier declarations, cost sheets, process charts) must be kept for five years for audit by Japan Customs.

Japan Customs accepts advance rulings on origin for the EU EPA but these are not mandatory. Minimal operations, as set out in Article 3.26, do not confer origin even if other requirements are met—mirroring exclusion lists in CPTPP and RCEP.

Japanese Economic Partnership Agreements (EPAs) such as CPTPP and RCEP explicitly permit producers to treat self-produced or intermediate materials as "originating" in the calculation of origin for finished goods, provided those intermediates meet their own rule of origin. This rule streamlines the proof burden on complex Japanese supply chains, especially in auto, electronics, and machinery sectors.

Definition: An intermediate material ("self-produced input") is any good that is made by the exporter/producer and then used in the production of a final export good. If, for example, a Japanese plant manufactures an electronic module from multiple inputs and then uses that module in a finished device, the module can be counted as an originating intermediate if it meets its own Product-Specific Rule (PSR). The producer then does not need to trace all of the module’s constituent materials again when calculating origin for the finished device.

CPTPP (Article 3.9; Japan Customs Guideline, section 4.2, Example 4): Allows a producer to designate any self-produced material as an “intermediate material” if it satisfies its own origin rule (PSR), whether that is wholly obtained, change in tariff classification (CTC), regional value content (RVC), or a process rule. Once designated, only the status or value of the intermediate needs to be counted for upstream calculations—tracing to its underlying components is not required for the final good. The intermediate’s supporting records must document that it satisfied its own origin criteria. Five-year documentation retention is required for CPTPP claims (Guideline, Section 7.4).

RCEP (Article 3.9): RCEP uses nearly identical logic. The exporter/producer can treat self-produced inputs as originating if the intermediate meets its own rule of origin, and only its status or value is considered for the final product’s claim. RCEP does not use exactly the same terms—"self-produced material" is the language of Article 3.9—but the operational mechanics are parallel. Again, compliance turns on the intermediate’s own documentation demonstrating that it qualifies under its relevant PSR.

Documentation: Japan Customs specifies (for CPTPP) that supporting evidence for each self-produced intermediate must be retained to demonstrate PSR qualification. Failure to document the intermediate’s status is grounds for denial of preference in post-clearance audit. While both CPTPP and RCEP explicitly provide for this treatment, language in other EPAs (such as the Japan–EU EPA or Japan–UK CEPA) should be checked directly for precise rules; unable to confirm as of 2026-06-16 if self-produced intermediate provisions in those treaties exactly match CPTPP/RCEP.

The Japan–UK Comprehensive Economic Partnership Agreement (CEPA), in effect since January 1, 2021, sets out origin and documentation rules for goods imported into Japan from the United Kingdom. The CEPA closely follows the structure of the preceding Japan–EU EPA but features distinctions relevant to certification and compliance, especially for UK producers and exporters post-Brexit.

Product-Specific Rules (PSRs) and Origin Conferral Annex 3-B of the CEPA lists the product-specific rules (PSRs) by six-digit Harmonized System (HS) code. Goods generally qualify as originating if they satisfy one of the following:

• Wholly obtained or produced in the UK;
• Produced exclusively from originating materials; or
• Meet the PSR set for their HS classification.

PSR formats can include:

• Change in tariff heading (CTH) or subheading (CTSH), e.g., many machinery and electronics (HS 84–85) require CTH;
• Regional value content (RVC), typically 40% or 50%, used for various automotive (HS 87) and textile (HS 61/62) items;
• Specific process rules for goods in chemicals and textiles, e.g., stipulated chemical reaction requirements.

PSRs often offer “CTH or RVC 50%” alternatives—allowing importers to choose the easier pathway. The de minimis provision (Art. 3.7) permits goods to retain origin if up to 10% of the ex-works price is non-originating material, subject to some exceptions for sensitive products.

Statement on Origin: Documentation and Proof As with the Japan–EU EPA, CEPA eliminates certificates-of-origin by government authorities. Instead, importers submit a “statement on origin” made out by a UK exporter registered in the UK REX (Registered Exporter) system or by a Japanese importer. The statement must contain the specific text set out in Annex 3-D and may appear on an invoice or commercial document. For shipments up to ¥200,000, a statement is not required, but the importer must be able to prove origin on request. Supporting documents such as supplier declarations and production records must be retained for five years.

Minimal operations (Art. 3.26), as in RCEP and the EU EPA, do not confer origin regardless of paperwork. Advance origin rulings are available from Japan Customs but not mandatory.

Japan Customs accepts back-to-back certificates of origin and third-country invoices for preferential tariff claims under the ASEAN–Japan Comprehensive Economic Partnership (AJCEP) and the Regional Comprehensive Economic Partnership (RCEP), subject to strict procedural conditions. These mechanisms support integrated regional supply chains where goods are shipped or re-invoiced through intermediaries but maintain originating status.

Back-to-back certificates (AJCEP & RCEP)

Under AJCEP and RCEP, when eligible goods are exported from a Party and re-exported to Japan via an intermediate Party, the customs authority in the transit country can issue a new certificate of origin (a "back-to-back" certificate). This is permitted if the goods have not undergone further processing except allowed minimal operations (such as splitting consignments or repacking) and documentation demonstrates a continuous origin chain. For RCEP, Article 3.18 and Japan Customs public guidance specify that the new certificate or origin statement must reference the original document from the first exporting Party, and both documents must be retained by the importer for audit. AJCEP’s RoO procedures similarly require the back-to-back certificate to show clear cross-reference to the original certificate and to certify uninterrupted custody and compliance with consignment criteria.

Third-country invoicing (AJCEP & RCEP)

Japan Customs’ official FAQ and EPA procedure guides confirm that imports into Japan under AJCEP or RCEP may be accompanied by a commercial invoice issued by a company established in a third country (not the exporting or importing Party), as is common with regional trading hubs or group sales entities. The preference claim is valid so long as (1) the origin certificate or origin statement conforms to AJCEP or RCEP requirements, (2) the invoice and supporting documents establish an unbroken chain from exporter to importer, and (3) all goods on the invoice are covered by the referenced origin documentation. No further specific annotation for third-country invoicing is currently mandated by public Japan Customs procedural guidance, but all documentation must be submitted if requested during post-import verification.

Documentation and compliance

• Importers must keep originals (or validated copies) of both the initial and back-to-back certificates (RCEP/AJCEP) and all commercial invoices, supplier declarations, and shipping documents.
• The procedures for referencing and validating back-to-back certificates are detailed in Japan Customs’ RCEP and AJCEP portals; templates and FAQ are available online and should be checked for current formatting requirements as published by Customs.
• If any part of the documentary chain cannot be established, Japan Customs may deny preference and subject the goods to normal MFN duties.

As of 2026-06-16, the published rules for back-to-back origin certification and third-country invoicing in the RCEP and AJCEP regimes remain as described above; for other EPAs, unable to confirm identical procedures from primary Japan Customs sources.
