Origin & Preferential Duty Checker
Use a short checklist to identify origin, destination and tariff facts that may change the duty treatment.
Origin treatment is not determined by code alone
For goods from China entering United States, check MFN treatment, free-trade eligibility, origin rules and any trade remedies.
This tool is a screening checklist, not a preferential-origin determination. A certificate, substantial-transformation analysis or agency ruling may be required.
Why origin matters
A tariff code alone does not determine the final duty. Agreements, substantial transformation, quotas and trade remedies can all depend on origin and supporting documents.
