A Certificate of Origin (CO) is an official document stating where the vehicle was manufactured. For imports from China, it matters more than many buyers expect.
First, customs value: many countries apply duty rates based on the country of manufacture, not where you bought the car. A CO proves the vehicle is Chinese-built, which determines the correct tariff line—skipping it can mean reassessment, fines, or seizure at destination.
Second, trade agreements: some countries have preferential tariffs for Chinese goods that only apply with a valid CO.
Request a CO issued by the China Council for the Promotion of International Trade (CCPIT) or China Customs, not a self-printed form. Check that the VIN, engine number, and buyer details match your purchase documents exactly.
Make receiving the CO a condition before your final payment, and keep the original—customs at destination will ask for it.
