TD

Country of origin is the country where a product is manufactured, produced, or substantially transformed for customs purposes. It is not necessarily the country the goods were shipped from, exported through, or purchased from. For example, assembling, processing, or combining materials in another country may or may not change origin, depending on the product and the applicable customs rules.

Origin matters because tariff measures are often applied based on the origin of the goods, along with their tariff classification and other facts. In a measure tracker, “TD” should be read according to the page’s stated measure-type definition; verify what TD covers and whether it applies to the product’s origin, classification, or another condition. Common pitfalls include confusing shipment country with origin, assuming the last country of assembly always determines origin, overlooking processing in multiple countries, and relying on supplier statements without supporting records.

What to check

• Confirm the product’s customs origin using the applicable origin rules for its tariff classification; obtain broker or customs advice when the manufacturing process is complex.
• Map the full production chain, including the countries supplying materials, components, assembly, and substantial processing.
• Collect and retain manufacturing records, bills of materials, supplier origin statements, production descriptions, and commercial documents that support the origin conclusion.
• Check that the declared origin matches the entry data, marking or labeling requirements, preferential-trade claims, and any country-specific measure conditions.
• Review the tracker’s definition of “TD” and confirm the measure against current official tariff and customs sources before applying it.
