Hong Kong

For US customs, the country of origin is generally where a product was manufactured, produced, or grown—not the place it was shipped from, sold from, or routed through. For goods associated with Hong Kong, do not assume that a Hong Kong shipping address or export document establishes origin; review how and where the goods were actually made.

Origin matters because US trade measures, tariff treatments, marking rules, quotas, and other requirements can apply differently depending on origin. If production occurs in more than one country, customs may apply the substantial transformation test: identify the country where the product became a new article with a different name, character, or use. The analysis can be fact-specific, and simple packaging, relabeling, or transshipment usually does not change origin.

What to check

• Trace the product’s manufacturing steps, components, and processing locations, including any work performed in Hong Kong and elsewhere.
• Apply the relevant US origin rule for the product’s tariff classification; do not rely only on the seller’s invoice, ship-from address, or country-of-export field.
• Collect and retain supplier origin statements, bills of materials, production records, invoices, and transport documents that support the claimed origin.
• Check whether processing in another country substantially transformed the goods, and document the facts used in that analysis.
• Verify the result against current official US Customs and tariff guidance, or ask a customs broker for a binding ruling or professional review when the facts are complex.
