Do Not Wait for Customs to Find Your USMCA Mistakes
One unsupported USMCA certificate can create duty exposure, penalties, documentation requests, and border delays. Frontier helps importers, exporters, and manufacturers review origin claims before CBP or CBSA does.
If your supply chain includes Chinese or other non-originating components, your duty-free treatment may not be as defensible as you think.
USMCA claims require proper origin support. If the certificate, supplier documentation, tariff classification, or value calculations are not defensible, duty-free treatment can be challenged during a customs review.
The China Component Problem
USMCA is designed to support North American trade and production. That means goods with significant non-originating content may not qualify for duty-free treatment unless they meet the applicable rules of origin.
Many companies rely on supplier certificates or internal assumptions without confirming whether the underlying documentation supports the claim. That can create exposure when CBP, CBSA, or another customs authority asks for proof.
Frontier’s USMCA Origin Verification support helps identify documentation gaps, origin risks, and areas where a claim should be reviewed before it becomes a customs problem.
Who This Applies To
This service is designed for businesses already using, preparing, or relying on USMCA duty-free treatment and need confidence that their origin claims can be supported.
- Importers relying on USMCA certificates from suppliers
- U.S. exporters selling goods into Canada or Mexico
- Manufacturers with Chinese or other offshore components
- Companies unsure whether their origin documentation is complete
Why USMCA Claims Fail Reviews
Most USMCA issues are not caused by one obvious mistake. They are usually caused by unsupported assumptions, incomplete supplier records, weak classification logic, or undocumented origin calculations.
Chinese Component Risk
Goods with Chinese or other offshore components may not qualify if the applicable rules of origin are not met or if the supporting records do not prove qualification.
Unsupported Certificates
A certificate alone is not enough if the importer cannot support the claim with supplier records, product details, tariff classification, and origin analysis.
Border and Audit Exposure
When a claim is challenged, shipments may face documentation requests, added scrutiny, duty reassessment, or delays that affect supply chain reliability.
What We Review
Frontier reviews the information behind your USMCA claim so your team can understand whether the duty-free treatment is properly supported.
USMCA Certificates
Review certificate structure, claim details, responsible parties, and whether the documentation supports the stated origin claim.
Supplier Documentation
Review vendor declarations, supporting records, component origin, and whether supplier documentation is complete enough to support the claim.
Tariff Classification Logic
Review whether HTS classification and origin logic align with the rule being used to claim USMCA preference.
Regional Value Content
Review whether available cost, component, and production information supports the required regional value content where applicable.
Manufacturing and Transformation
Review whether the production process supports the required tariff shift, transformation, or rule-specific qualification path.
China and Offshore Content
Identify non-originating inputs that may weaken the claim or require additional support before duty-free treatment is applied.
The Review Process
Submit Documentation
Provide certificates, supplier declarations, product details, classifications, and available cost or component records.
