Controlled items: list structure and classification methodology
Mexico's dual-use export control lists are organized in five annexes to the Acuerdo que establece los bienes de uso dual, software y tecnologías cuya exportación está sujeta a regulación por parte de la Secretaría de Economía (27 December 2020, as modified 24 November 2022). Each annex corresponds to controlled goods, software, and technologies that are susceptible to diversion for the proliferation and manufacture of conventional weapons and weapons of mass destruction.
Annex structure. The five annexes divide controlled items by international control regime and end-use concern:
- Anexo I — Dual-use goods, software, and technologies from the Wassenaar Arrangement on Export Controls for Conventional Arms and Dual-Use Goods and Technologies. Mexico became a Wassenaar participating state on 20 January 2012. Anexo I tracks the Wassenaar dual-use list structure: nine categories organized by technology domain (0 = nuclear materials, facilities, and equipment; 1 = special materials and related equipment; 2 = materials processing; 3 = electronics; 4 = computers; 5 = telecommunications and information security; 6 = sensors and lasers; 7 = navigation and avionics; 8 = marine; 9 = aerospace and propulsion).
- Anexo II — Conventional arms, parts, and components from the Wassenaar Munitions List (ML1 through ML22). This annex covers items such as military firearms, military explosives, armored vehicles, military aircraft, and directed-energy weapons.
- Anexo III — Software and technologies of dual use from the Wassenaar Arrangement, cross-referenced to the software and technology sections of the nine dual-use categories.
- Anexo IV — Nuclear dual-use equipment, materials, and software from the Nuclear Suppliers Group (NSG). Items are organized by NSG part 1 (nuclear-specific) and NSG part 2 (nuclear-related dual-use).
- Anexo V — Chemical and biological items controlled under the Australia Group framework (precursors for chemical and biological weapons, related equipment, and technology).
Classification methodology. Controlled items in the Acuerdo are identified by TIGIE tariff classification (Tarifa de la Ley de los Impuestos Generales de Importación y de Exportación — Mexico's tariff schedule based on the Harmonized System), cross-referenced to the relevant Wassenaar, NSG, or Australia Group control-list code. Each line in the Anexos lists a TIGIE fracción arancelaria (tariff heading) followed by the word "Únicamente:" (Only:) and a technical description of the controlled item, along with its Wassenaar category and subcategory code (e.g., "1.A.2.b.1." for certain carbon fiber filaments) or NSG/AG equivalent.
An exporter determines whether a specific good, software, or technology requires a permiso previo de exportación by performing two classification steps:
- Tariff classification — Classify the good under the applicable TIGIE fracción arancelaria according to the General Rules of Interpretation of the Harmonized System.
- Technical parameter verification — For that TIGIE fracción, check whether the good meets the technical specifications listed in the "Únicamente:" limitation. If the good's technical parameters (material composition, performance threshold, dimensional tolerance, end-use design) match or exceed the controlled specification, the item is subject to prior export permit. If the good falls within the TIGIE fracción arancelaria but does not meet the technical parameters, no permit is required under the Acuerdo.
Annexo VII definitions. Anexo VII of the Acuerdo provides technical definitions for terms used throughout the control lists. For example, "Fabricación" (production) is defined as "all stages of production, such as: engineering, manufacture, integration, assembly (mounting), inspection, testing, quality assurance," mirroring Wassenaar definitional conventions. Terms appearing in quotation marks within the Anexos (such as "materiales fibrosos o filamentosos" or "asistencia técnica") are defined in Anexo VII.
List updates. Article Vigésimo Primero of the Acuerdo requires the Comisión de Comercio Exterior (COCEX), upon recommendation from the Comité Interinstitucional de Control de Exportaciones, to review and approve updates to Anexos I through VI at least once per year in order to conform to Mexico's obligations as a member of the international nonproliferation regimes. The Secretaría de Economía publishes updated annexes in the Diario Oficial de la Federación; the most recent comprehensive revision was published on 24 November 2022.
Consultation tools. Exporters may consult the full text of the Acuerdo annexes at the SNICE (Sistema Nacional de Información de Comercio Exterior) website maintained by the Secretaría de Economía. SNICE provides a searchable database correlating TIGIE fracciones arancelarias to Wassenaar, NSG, and Australia Group control codes, along with user guides for prior export permit applications through the Ventanilla Única de Comercio Exterior Mexicana (VUCEM).

License application procedure and processing times
An exporter must obtain a permiso previo de exportación (prior export permit) before shipping any dual-use good, software, or technology listed in Anexos I through V of the Acuerdo que establece los bienes de uso dual, software y tecnologías cuya exportación está sujeta a regulación por parte de la Secretaría de Economía (27 December 2020, as modified). The application is submitted electronically through the Ventanilla Única de Comercio Exterior Mexicana (VUCEM), Mexico's Single Window for Foreign Trade. Paper applications are not accepted.
Application pathway. The exporter logs into VUCEM at www.ventanillaunica.gob.mx using an electronic signature (e.firma), navigates to Solicitudes Nuevas > Secretaría de Economía > Permisos de Importación y Exportación > Exportación > Permiso Previo Control de Exportaciones, and completes form SE-FO-03-081 ("Permiso previo de exportación de armas convencionales, sus partes y componentes, bienes de uso dual, software y tecnologías susceptibles de desvío para la fabricación y proliferación de armas convencionales y de destrucción masiva y sus modificaciones"). VUCEM registration requires a valid Registro Federal de Contribuyentes (RFC) and a current e.firma issued by the Servicio de Administración Tributaria (SAT). No fees are charged for the issuance of prior export permits or for modifications to existing permits.
Required data fields. Form SE-FO-03-081 requires the exporter to declare:
- Product description — the technical specification of the dual-use good, software, or technology to be exported, with sufficient detail to match the controlled item listed in the applicable Anexo.
- TIGIE tariff classification — the fracción arancelaria under the Tarifa de la Ley de los Impuestos Generales de Importación y de Exportación that corresponds to the controlled item.
- Export regime — whether the export is definitive or temporary.
- Quantity and value — the quantity (units, kilograms, liters, as applicable) and the total commercial value.
- Country of destination — the final country to which the item will be shipped.
- End user and end use — the identity and address of the foreign consignee and a description of the intended end use. This information forms part of the Manifestación de Uso y Usuario Final (end-use and end-user certification), submitted on form SE-03-080, which accompanies the permit application.
For goods that are used, the exporter must select "Nuevo" in the product-status field and describe the used condition in the observations box. When the export covers more than one TIGIE fracción arancelaria, the Secretaría de Economía's guidance instructs the exporter to contact the Dirección General de Facilitación Comercial y de Comercio Exterior (DGFCCE) for further instructions.
Processing times. Article Décimo of the 2020 Acuerdo establishes that the DGFCCE will resolve the application within 10 business days, counted from the business day following the date the application was submitted through VUCEM. When the DGFCCE requires additional information from the exporter, the resolution deadline extends to 60 business days from the date the Manifestación de Uso y Usuario Final was presented. The Acuerdo does not specify how many times the DGFCCE may request additional information or whether the 60-day period restarts with each request; the text states only that "the deadline to notify acceptance of the Manifestación de Uso y Usuario Final for obtaining the prior export permit … shall be extended up to 60 business days."
Issuance and transmission. The DGFCCE issues the permit through VUCEM and transmits it electronically to the Administración General de Aduanas (AGA) of the Servicio de Administración Tributaria so that the exporter may complete customs clearance. The exporter receives an electronic acknowledgment of receipt and may print the permit directly from VUCEM. The permit number must be declared in the pedimento (customs declaration) at the port of export.
Permit validity and renewal. Article Décimo Tercero of the 2020 Acuerdo provides that prior export permits are valid for up to one year. The permit may be extended for an additional period of equal duration, provided the export continues to satisfy the authorization criteria, the permit remains current, and unused authorized quantities remain. Extensions are requested through VUCEM by emailing the DGFCCE; the 2020 Acuerdo does not prescribe a specific electronic workflow for extensions within VUCEM, and the SNICE user guide (November 2022) instructs applicants to submit extension requests by email rather than through the VUCEM portal.

End-use and end-user certification requirements
Every application for a permiso previo de exportación (prior export permit) of dual-use goods, conventional arms, software, or technologies under the Acuerdo que establece los bienes de uso dual, software y tecnologías cuya exportación está sujeta a regulación por parte de la Secretaría de Economía (27 December 2020, as modified) must be accompanied by a Manifestación de Uso y Usuario Final (end-use and end-user certification), submitted on form SE-FO-03-080. This certification is the foundational risk-screening document; the Dirección General de Facilitación Comercial y de Comercio Exterior (DGFCCE) uses it to assess whether the export presents a diversion risk for the manufacture or proliferation of conventional weapons or weapons of mass destruction.
Definition and purpose. Article Primero, fraction XIX of the 2020 Acuerdo defines the Manifestación de Uso y Usuario Final as "the export-control document by which the exporter describes the use, end user, and final destination to which the controlled goods are subject." The certification is submitted electronically through VUCEM as an attachment to the permit application (form SE-FO-03-081). Article Noveno of the Acuerdo mandates that the certification "must be attached through the Ventanilla Digital" when the exporter submits the permit application. The DGFCCE analyzes both the permit application and the certification together to reach a decision on whether to issue, deny, or request additional information.
Required information fields. The Manifestación de Uso y Usuario Final must declare, under penalty of perjury:
- End user — the identity, complete legal name, address, and contact information of the foreign consignee (the person or entity that will take physical possession of the dual-use goods, software, or technology).
- End use — a detailed description of the intended application of the goods. The exporter must explain why the end user needs the item and for what purpose it will be employed. Generic descriptions (e.g., "industrial use") are insufficient; the DGFCCE expects technical specificity. For example, if exporting a carbon-fiber filament controlled under Wassenaar Category 1.C.10., the exporter should state "manufacture of composite structural components for civil aircraft fuselages" rather than "manufacturing purposes."
- Final destination — the last physical location to which the controlled goods will be shipped. Article Primero, fraction IX defines "Destino final" as "the last point at which the controlled goods arrive." If the goods will be re-exported onward from the first country of import, the Manifestación must disclose that fact and identify the ultimate destination.
- Certification of non-diversion — the exporter must certify that the goods will not be diverted to an end user, end use, or final destination other than those declared in the Manifestación and authorized in the permit. Article Primero, fraction X defines "Desvío" (diversion) as "the use of dual-use goods, software, and technologies by an end user, for an end use, or for a final destination different from those stated in the Manifestación de Uso y Usuario Final … and authorized in the prior export permit."
Supporting documentary evidence. The catalog entry for form SE-03-080, published by the Comisión Nacional de Mejora Regulatoria (CONAMER) at catalogonacional.gob.mx, specifies that the exporter must also submit "any document that demonstrates that the declared end use, end user, and final destination are accurate, and that proves there will be no diversion for the manufacture of conventional weapons, their parts and components, dual-use goods, software, and technologies, by an end user or for an end use other than those stated in the Manifestación … and authorized in the prior export permit (for example: invoice, international sales contract, etc.)." Typical supporting documents include a purchase order, an international sales contract, a pro-forma commercial invoice, or a letter from the end user on company letterhead describing the intended use.
Risk analysis and discretionary authority. The CONAMER catalog entry for SE-03-080 states that the Secretaría de Economía will conduct a "risk analysis" (análisis de riesgo) of the application. It notes that the permit will be denied if "the risk analysis conducted by the SE determines that the end use could be for the proliferation of conventional weapons, their parts and components" or for the proliferation or manufacture of weapons of mass destruction. The 2020 Acuerdo does not prescribe scoring criteria or red-flag lists; the DGFCCE retains discretion to deny permits or request additional documentation when the declared end use, end user, or destination raises nonproliferation concerns. The SE does not publish denials, and there is no formal administrative appeals procedure set out in the 2020 Acuerdo for applicants whose permits are denied; the applicant may re-apply with revised information or seek judicial review under the Ley Federal de Procedimiento Administrativo.
Broker registry and information sharing. Article Décimo Primero of the 2020 Acuerdo provides that "the DGFCCE will maintain a registry of brokers derived from the Manifestaciones de Uso y Usuario Final … submitted, and will exchange that registry with other States in accordance with Article Vigésimo of this Acuerdo." Mexico shares end-user certification data with other Wassenaar Arrangement participating states, the Nuclear Suppliers Group, and Australia Group partners as part of its international nonproliferation commitments. Exporters should be aware that end-user and end-use information submitted in the Manifestación may be shared with foreign export-control authorities and that discrepancies between the declared end use and observed end use can result in the exporter being placed on international denial or watch lists.
No filing fees. As noted in Article Décimo Noveno of the 2020 Acuerdo, "no fees are charged for the issuance of prior export permits or for modifications to existing permits." The Manifestación de Uso y Usuario Final submission itself carries no fee.

Criminal and administrative penalties for violations
Exporting controlled dual-use goods, conventional arms, software, or technologies without a permiso previo de exportación or in violation of the terms of an issued permit exposes the exporter to criminal prosecution for smuggling (contrabando) under the Código Fiscal de la Federación (Federal Tax Code) and to administrative fines and sanctions under the Ley Aduanera (Customs Law). Both penalties may be imposed simultaneously: criminal liability does not bar administrative fines, and payment of administrative fines does not extinguish criminal liability.
## Criminal liability: smuggling (contrabando)
Article 102 of the Código Fiscal de la Federación defines the federal crime of contrabando (smuggling). Under Article 102, fraction II, a person commits smuggling when they introduce goods into the country or extract goods from the country "without the permit of the competent authority, when such permit is required" (sin permiso de las autoridades competentes, cuando sea necesario este requisito). Because the Acuerdo que establece los bienes de uso dual, software y tecnologías cuya exportación está sujeta a regulación por parte de la Secretaría de Economía (27 December 2020, as modified) subjects the export of dual-use items listed in Anexos I through V to a prior export permit issued by the Secretaría de Economía, the export of any such item without a valid permit or in a manner that exceeds the permit's authorized scope constitutes smuggling under Article 102, fraction II.
Article 104 of the Código Fiscal de la Federación prescribes the penalties for smuggling. Under Article 104, fraction IV, when the smuggling consists of exporting goods whose export is subject to a regulatory permit requirement (cuando se trate de mercancías cuya importación o exportación esté sujeta a regulaciones o restricciones no arancelarias), the penalty is imprisonment of three months to five years. The exact term within this range is determined by the criminal court based on aggravating or mitigating factors, including the value of the goods, whether the exporter acted with knowledge or intent, whether false documentation was submitted, and whether the exporter has prior convictions for tax or customs offenses.
Under Article 105 of the Código Fiscal de la Federación, the following conduct is assimilated to smuggling (equiparable a contrabando) and punishable under the same Article 104 penalty framework:
- Omitting or falsifying information in the customs declaration (pedimento) or in the permit application, when the omission or falsification results in the evasion of the permit requirement or in the shipment of goods in quantities or specifications that exceed the authorized permit (Article 105, fraction I).
- Submitting false end-use or end-user certifications (Manifestación de Uso y Usuario Final) to obtain a permit or to evade denial. The Código Fiscal treats false certifications submitted to customs or regulatory authorities as a form of fraudulent evasion under Article 105, and prosecutors routinely charge exporters who submit fabricated end-user letters or who divert dual-use goods to unauthorized end users with smuggling or tax fraud under Articles 105 and 108.
Voluntary disclosure and mitigation. Article 73 of the Código Fiscal de la Federación provides that a person who voluntarily corrects a customs or export-control violation before the tax or customs authority initiates an audit or investigation may qualify for reduced or suspended criminal penalties, provided the exporter pays any administrative fines imposed and regularizes the export (by obtaining the permit retroactively, if the Secretaría de Economía permits such retroactive regularization, or by re-importing the goods). Voluntary disclosure does not eliminate criminal liability entirely, but Mexican federal prosecutors have discretion under Article 73 to decline prosecution when the exporter demonstrates good faith and cooperates fully. There is no statutory safe-harbor procedure specific to dual-use export violations; the general Article 73 framework applies.
## Administrative fines and sanctions under the Ley Aduanera
Article 176 of the Ley Aduanera (Customs Law) catalogues administrative infractions (infracciones) related to import and export violations. Under Article 176, fraction III, it is an infraction to export goods when their export is prohibited or when the export is subject to a permit, authorization, or other non-tariff regulatory requirement and the exporter does not comply with that requirement. Article 177, fraction II elaborates: it is an infraction to introduce goods into Mexico or to extract goods from Mexico **"without the permit of the competent authorities or without the electronic signature on the pedimento that demonstrates the complete or partial discharge of the permit before undertaking customs clearance procedures, or without complying with any other non-tariff regulations or restrictions issued under the Ley de Comercio Exterior, international commitments, or public-order requirements."**
Article 178 of the Ley Aduanera prescribes administrative fines for these infractions. Under Article 178, fraction III (which corresponds to the infraction defined in Article 176, fraction III, and Article 177, fraction II), the sanction is:
- A fine equal to 70% to 100% of the commercial value of the goods (multa equivalente del 70% al 100% del valor comercial de las mercancías), when the goods are subject to a permit requirement and the exporter did not obtain the permit or did not comply with its terms.
- Seizure of the goods (embargo precautorio de las mercancías) by the Administración General de Aduanas (the Customs Administration of the Servicio de Administración Tributaria, SAT) if the violation is detected before the goods physically exit Mexican territory. Under Article 151 of the Ley Aduanera, seized goods are held in customs warehouses pending resolution of the administrative case; if the exporter does not regularize the shipment within the period set by the customs authority (typically 30 days), the goods are subject to forfeiture and public auction.
- Cancellation of the exporter's registration in the Padrón de Importadores y Exportadores (Importer and Exporter Registry) maintained by SAT. Article 59 of the Ley Aduanera grants SAT the authority to suspend or cancel an exporter's registration when the exporter has committed serious or repeated violations of export regulations. Cancellation bars the exporter from engaging in foreign-trade operations; reinstatement requires a new application and demonstration of compliance systems, and the exporter must wait at least two years from the cancellation date.
Article 202 of the Ley Aduanera specifies additional fines for failure to transmit export-permit documentation to the customs authority. When an exporter holds a valid permiso previo de exportación but fails to transmit the permit document electronically through VUCEM to the customs broker or fails to declare the permit number in the pedimento, the exporter is subject to a fine in the amount set by Article 202. The fine amount is indexed annually; as of the 27 December 2025 update to the Ley Aduanera published in the Diario Oficial de la Federación, the fine range for failure to transmit permit documentation is MXN 3,870 to MXN 5,800 per shipment. This fine is in addition to any other administrative or criminal penalty if the underlying goods were in fact exported without a valid permit.
Cumulative liability. Administrative fines under the Ley Aduanera are imposed independently of criminal prosecution under the Código Fiscal. Article 178, final paragraph, of the Ley Aduanera provides that the imposition of administrative fines "will be without prejudice to criminal liability that may arise" (sin perjuicio de la responsabilidad penal que pudiera resultar). In practice, SAT issues a formal administrative resolution (resolución determinante) assessing the fine, and the exporter has 30 business days to pay or to challenge the resolution through the administrative appeal procedure (recurso de revocación) under Article 116 of the Código Fiscal or through direct judicial review before the Tribunal Federal de Justicia Administrativa. Separately, the Fiscalía General de la República (federal prosecutor) determines whether to file criminal charges for smuggling; the two proceedings run in parallel.
## Recordkeeping and audit period
Article 30 of the Código Fiscal de la Federación requires exporters who obtained a permiso previo de exportación to maintain custody of all records that demonstrate compliance with the permit's terms—including the permit itself, the Manifestación de Uso y Usuario Final, the commercial invoice, the bill of lading or airway bill, the pedimento, and any correspondence with the Secretaría de Economía or with the foreign end user—for a period of five years from the date of the export. Article 67 of the Código Fiscal grants SAT the authority to conduct verification procedures and audits of export-control compliance during this five-year period. Failure to produce records upon audit request is itself an infraction under Article 83 of the Código Fiscal, punishable by fines of MXN 17,020 to MXN 34,030 (indexed amounts as of 2026) for each month or partial month during which the records are not produced.
