Country of origin: the manufacturing country
Country of origin is the country where the product was manufactured, produced, or substantially transformed. It is not the ship-from country, the warehouse country, or the seller country. For example, a product made in China and shipped from a US warehouse has country of origin China, not United States. Customs authorities use country of origin to determine duty rates, apply trade measures, and verify trade agreement eligibility.
- Country of origin = manufacturing country
- Not the ship-from country or warehouse country
- Not the seller or brand country
- Determined by where the product was made or substantially transformed
Why country of origin is required
Customs authorities require country of origin to calculate duty, apply trade measures, and verify trade agreement eligibility. Many countries apply additional tariffs (such as Section 301 in the US) based on country of origin. Free trade agreements (FTAs) require country of origin to determine if preferential duty rates apply. Without country of origin, the shipment cannot clear customs.
- Duty calculation: duty rates vary by origin
- Trade measures: Section 301, anti-dumping, countervailing duties
- Trade agreements: FTAs require origin for preferential rates
- Statistics: governments track trade flows by origin
- Restrictions: some products are restricted from certain origins
How to determine country of origin
Country of origin is determined by where the product was manufactured or where it underwent substantial transformation. Substantial transformation means a significant change in form, character, or use. For most ecommerce products, the origin is the country where the final assembly or manufacturing took place. If a product is assembled in Vietnam from Chinese components, the origin is typically Vietnam (where assembly occurred), not China (where components came from).
- Manufacturing country: where the product was made
- Substantial transformation: where the product changed form or character
- Final assembly: often determines origin for assembled products
- Verify with customs broker or trade attorney for complex cases
How to declare country of origin on the commercial invoice
Country of origin must be declared on the commercial invoice for each line item. The format is typically the country name or ISO code (e.g., CN for China, VN for Vietnam). Declare it in the "Country of Origin" column or field. Some invoices combine country of origin with HS code on the same line. Verify the destination country requirements for the exact format.
- Declare on the commercial invoice for each line item
- Use country name or ISO code (CN, VN, US, etc.)
- Combine with HS code on the same line if format allows
- Verify destination country requirements for exact format
Common mistakes with country of origin
The most common mistake is using the ship-from or warehouse country instead of the manufacturing country. Other mistakes include omitting country of origin entirely, using the brand country instead of the manufacturing country, and not updating origin when the supplier changes. For multi-origin products (components from multiple countries), the origin is where the final substantial transformation occurred.
- Using ship-from country instead of manufacturing country
- Omitting country of origin on the invoice
- Using brand country instead of manufacturing country
- Not updating origin when supplier changes
- Treating multi-origin products as having no single origin
Ecommerce example
A Shopify seller in the US imports phone cases from a Chinese supplier. The cases are manufactured in Shenzhen, China, and shipped to a US warehouse in Los Angeles. When fulfilling a US customer order, no customs entry is needed (domestic shipment). When fulfilling a Canadian customer order, the case ships from the US warehouse to Canada. The country of origin is China (where the case was made), not United States (the ship-from country). The Canadian customs entry requires country of origin China.
