USMCA can provide preferential tariff treatment for qualifying North American goods, but a shipment does not qualify simply because it comes from Mexico. Importers need product-specific classification, an applicable rule of origin, a valid certification, and records supporting the claim.
Identify the importer of record
The parties should agree who will act as importer of record, engage the customs broker, provide data, pay duties and fees, and retain required records. The purchase agreement and Incoterm should align with the practical customs arrangement rather than contradict it.
Classify the product
The Harmonized Tariff Schedule classification drives ordinary duty, possible trade remedies, agency requirements, and the product-specific origin rule. Classify the finished good and, where the origin rule requires it, relevant materials. Product names used in sales are rarely sufficient for customs classification.
Determine origin under the applicable rule
Origin can depend on where a good is wholly obtained, a required tariff shift, regional value content, a specific production process, or another product rule. Mexican assembly of non-originating inputs may or may not be enough. USTR publishes the agreement text and uniform regulations for detailed analysis.
Prepare the certification
CBP explains that USMCA does not require a single prescribed certificate form, but the certification must contain nine minimum data elements. It may be completed by the importer, exporter, or producer when the certifier has an appropriate basis. Blanket periods and electronic formats can be used where requirements are met.
Maintain reasonable support
Keep the bill of materials, supplier origin statements, production records, calculations, classification rationale, purchase documents, and certification. Establish a process for expired certificates and changes to material sources or manufacturing steps. A claim should be reviewed when the product or supply chain changes.
Check other import requirements
USMCA is only one part of compliance. Products may require country-of-origin marking and oversight by FDA, EPA, DOT, FCC, CPSC, USDA, or other agencies. Packaging materials, wood, food, chemicals, electronics, and regulated products can carry additional obligations.
Build customs data into supplier onboarding
- Legal entity and facility information
- Accurate product descriptions and part numbers
- Tariff classifications and origin analysis
- Material origin and producer records
- Commercial invoice and packing-list standards
- Broker contacts and document deadlines
- Exception and post-entry correction procedures
Useful official resources include U.S. Customs and Border Protection and the U.S. Trade Representative.
Treat origin as a controlled data process. Procurement, the supplier, logistics, customs, finance, and compliance all need the same documented facts before preference is claimed.
