What Is Country of Origin? Marking Rules & Determination for US Imports

Country of origin is the country where imported goods were manufactured, produced, or grown. In US customs law, it is the single most consequential determination for any import because it dictates the duty rate applied (MFN rates vary by country), eligibility for preferential trade agreements (USMCA, GSP, CAFTA-DR), exposure to special tariffs (Section 301 on China, Section 232 on steel/aluminum), mandatory product marking ("Made in ___"), and eligibility for government procurement contracts. Getting country of origin wrong can mean paying thousands of dollars in duties you don't owe — or failing to pay duties you do owe and facing penalties.

How CBP Determines Country of Origin

When goods are entirely grown, mined, or manufactured in a single country, the origin is straightforward. The complexity arises when materials from multiple countries are combined. CBP uses the "substantial transformation" test: goods acquire the origin of the country where they were last substantially transformed into a new and different article of commerce with a new name, character, or use. This is a case-by-case determination that considers the nature and complexity of the processing, the value added in each country, and whether the processing resulted in a fundamentally different product.

US Marking Requirements Under 19 USC 1304

Federal law (19 USC 1304) requires that every article of foreign origin imported into the United States be marked with the English name of the country of origin. The marking must be legible, permanent, and visible to the ultimate purchaser — the last person in the US who buys the article in its imported form. The marking must survive ordinary handling and use. For most products, this means stamped, printed, labeled, or engraved text reading "Made in [Country]" or "Product of [Country]."

What Happens If Marking Is Wrong or Missing?

• 10% ad valorem penalty — CBP can assess a marking duty of 10% of the customs value on articles not properly marked at the time of importation.
• Redelivery notice — CBP may order the goods returned to customs custody for proper marking, at the importer's expense.
• Seizure — Goods bearing false or misleading country of origin marks can be seized and forfeited.
• FTC enforcement — The Federal Trade Commission can pursue deceptive practices claims for misleading origin marks on consumer goods.
• Denied entry — In severe cases, improperly marked goods may be denied entry entirely.

Country of Origin vs. Country of Export

These are not the same. Country of export is where the goods were last shipped from. Country of origin is where they were made or substantially transformed. Goods manufactured in China but transshipped through Vietnam are still Chinese-origin — and still subject to Section 301 tariffs. CBP actively investigates transshipment fraud, using import pattern analysis, site visits, and data from foreign customs agencies. Penalties for fraudulent origin claims include duties owed plus interest, civil penalties up to $10,000 per violation, and potential criminal prosecution.

Special Rules for Specific Products

• Textiles and apparel — Origin is determined by the "wholly assembled" rule or the tariff shift rule under specific textile agreements, not the general substantial transformation test.
• USMCA goods — Origin is determined by the product-specific rules of origin in the agreement (tariff shift, regional value content, or both).
• Steel and aluminum — Subject to Section 232 tariffs based on the country where the steel/aluminum was smelted or cast, regardless of later processing.
• Food products — Must comply with USDA and FDA origin labeling requirements in addition to customs marking.

How Camtom Helps with Origin Compliance

Country of origin interacts directly with tariff classification — the HTS code determines which duty rate applies for each origin. Camtom's AI platform classifies products accurately and applies the correct duty rate for the declared origin, including all special tariffs, trade agreement preferences, and AD/CVD orders. Our engine flags when a different origin would result in significantly different duty treatment, helping importers and brokers ensure their origin declarations are both accurate and optimized.
