How do I determine a product's country of origin?
Updated: 2026-10-16
Short answer
Determine a product’s country of origin by applying the rules of the importing country to where the goods were wholly obtained or where the required production or transformation took place. Origin is not automatically the country from which the goods are shipped. Preferential origin under a free trade agreement may follow product-specific rules, such as a tariff change or regional value-content test.
How do I determine a product's country of origin?
A product’s country of origin is determined under the applicable customs rules. Depending on the product and legal purpose, the rules may consider where it was wholly obtained or where sufficient production or transformation took place. The country from which goods are shipped is not automatically their country of origin.
Separate origin from shipment country
A product’s country of origin is not necessarily the country it ships from, is invoiced in, or passes through. Customs origin rules determine which country is treated as the origin for the specific legal purpose. Simply storing, repacking, or transshipping goods does not automatically change origin.
Check where the product was obtained or made
Goods wholly obtained in one country may have a straightforward origin. When materials or components come from several countries, the applicable rules may require sufficient manufacturing or substantial transformation in a particular country.
Distinguish preferential and non-preferential origin
Non-preferential origin may be relevant for ordinary tariff treatment, marking, trade remedies, and other measures. Preferential origin determines whether a product qualifies for reduced or zero duty under a specific trade agreement or preference scheme.
Apply the relevant product-specific rule
An agreement may require a tariff classification change, regional value content, specified processing, or a combination of criteria. Rules vary by agreement and product, so do not assume that simple assembly or repackaging changes origin.
Keep evidence of production and sourcing
Maintain bills of materials, supplier declarations, production records, cost records where required, and supporting origin documents. Ensure any origin statement or certificate is accurate and can be substantiated.
