The practice advises importers and exporters on the full range of customs matters, including tariff classification, customs valuation, compliance with non-tariff regulations and restrictions. Our customs work encompasses compliance program design and implementation, prior disclosure of violations, customs audit management, and the resolution of classification and valuation disputes with customs authorities. We advise on the duty implications of supply chain restructurings, transfer pricing adjustments, and changes in sourcing strategy, helping clients identify opportunities to reduce duty exposure while maintaining full compliance with applicable customs laws. In an era of escalating tariff activity, including the imposition of additional duties under national security and reciprocal tariff frameworks, our customs advisory has become a central element of our clients’ trade strategy.

Our practice advises companies on determining compliance with the rules of origin established under FTAs, as well as on the qualification, certification, and substantiation of origin required to obtain preferential tariff treatment. We regularly assist clients in origin verification procedures conducted by Mexican customs authorities involving producers, exporters, and importers, as well as in audits and enforcement actions arising from the denial of FTA benefits.

Our international trade and customs team has successfully represented both Mexican and foreign companies in administrative and judicial proceedings concerning origin determinations, the application of preferential tariff treatment, and challenges to customs tax assessments.

As businesses continue to restructure their supply chains in response to nearshoring opportunities, geopolitical developments, and evolving trade policies, we help clients assess origin requirements, optimize sourcing and manufacturing structures, and maximize available tariff preferences while maintaining robust documentation, audit readiness, and compliance frameworks capable of withstanding regulatory scrutiny.

The practice advises companies on the design, implementation, and continuous improvement of comprehensive trade compliance programs. Our approach integrates trade compliance into clients’ broader risk management and corporate governance frameworks, ensuring that compliance functions are supported by effective policies, training programs, monitoring mechanisms, internal controls, and escalation protocols. We also advise on supply chain due diligence and responsible sourcing requirements that increasingly intersect with international trade regulation, including compliance with forced labor restrictions, supply chain traceability obligations, customs enforcement trends, and environmental, social, and governance (ESG) considerations. By combining regulatory, operational, and strategic perspectives, we help clients identify and mitigate trade compliance risks while enhancing supply chain resilience and supporting sustainable business growth.

Our team represents domestic and multinational companies in high-stakes customs and foreign trade audits, investigations, enforcement actions, and disputes that may significantly affect business operations, supply chains, and market access.

We advise clients on matters involving tariff classification, customs valuation, origin determinations, preferential tariff treatment, IMMEX compliance, Annex 24 inventory control requirements, VAT Certification compliance, and non-tariff regulations and restrictions.

We have extensive experience assisting companies in responding to customs and tax authority audits, challenging significant duty, tax, and penalty assessments, and addressing measures that threaten operational continuity, including customs seizures, embargoes of imported goods and productive assets, as well as the suspension or cancellation of IMMEX benefits and VAT Certifications. Our approach combines technical expertise with a practical understanding of manufacturing operations, supply chain management, and cross-border trade, allowing us to develop defense strategies that protect both legal positions and business objectives.

We regularly represent clients before administrative authorities and federal courts in administrative appeals, nullity proceedings, constitutional challenges, and amparo litigation, helping clients resolve complex disputes while safeguarding critical trade and manufacturing operations.

The practice has represented importers and exporters in antidumping and countervailing investigations and Federal courts. Our work encompasses the full lifecycle of trade remedy proceedings, from initial investigations through annual administrative reviews, sunset reviews, and appeals. Our team has deep experience in the procedural, economic, and evidentiary dimensions of trade remedy litigation, and we work closely with economists, industry analysts, and government affairs professionals to develop advocacy strategies that serve our clients’ commercial objectives.

The practice advises companies on compliance with export control regimes and economic sanctions programs administered by the relevant national authorities. Our work encompasses the classification of products, software, and technology under applicable control lists; the design and implementation of export compliance programs; the preparation of license applications and advisory opinion requests; and the management of voluntary self-disclosures when potential violations are identified. We counsel clients on the rapidly evolving sanctions landscape, including targeted sanctions, sectoral restrictions, and the secondary sanctions provisions that can affect transactions with no direct nexus to the sanctioning jurisdiction. For companies operating in highly regulated industries, including defense, aerospace, technology, energy, and financial services, our export controls and sanctions practice provides the specialized, jurisdiction-specific guidance required to operate with confidence in a complex and shifting regulatory environment.
