USMCA

The United States-Mexico-Canada Agreement, which replaced NAFTA on July 1, 2020, is a trilateral trade pact that directly affects how freight moves across North American borders and how supply chains are structured. For transport and logistics professionals, USMCA establishes the rules for tariff classification, rules of origin, cross-border trucking, and customs procedures that govern millions of shipments annually between the three nations.

Rules of origin are central to USMCA operations. Goods must meet specific content thresholds, measured as a percentage of value added within the bloc, to qualify for duty-free treatment. For automobiles, the agreement requires 75 percent North American content (up from 62.5 percent under NAFTA), with new labor value content requirements. A logistics firm moving automotive parts must verify these percentages; failure to do so exposes the shipper to retroactive tariffs and penalties that can reach millions of dollars on large shipments.

Practical impact on operations

Cross-border trucking operates under USMCA provisions that allow Mexican and Canadian carriers to operate throughout the United States and vice versa, though enforcement varies. Customs brokers must file entries correctly under USMCA to claim preferences; entries filed under the wrong tariff classification or without proper certificates of origin cannot be amended retroactively in most cases. Documentation requirements have tightened: importers now must maintain detailed records of material sourcing and manufacturing processes to support origin claims under audit.

The agreement created new complexity around digital trade, e-commerce duties, and intellectual property that affects specialized cargo like software, technical data, and patented components. Logistics providers handling these shipments face additional compliance layers. USMCA also includes provisions on environmental standards and labor practices that can trigger trade remedies if a supplier is found non-compliant.

Note: the acronym USMCA should not be confused with LOCODE designations, which are separate United Nations location codes used in cargo documentation. Each of the three countries maintains its own customs IT systems; harmonization between them remains incomplete, creating friction points at major ports of entry like Laredo, El Paso, and the Port of Los Angeles.
