A Certificate of Origin (C/O) is an official document stating where the vehicle was manufactured. Customs authorities use it to decide which tariff rates and trade agreements apply to your import. Why it matters: many countries offer preferential tariffs for certain origins. With a valid C/O, such as the ASEAN-China Form E or a GSP Form A, you may pay reduced or zero duty. Without it, you typically pay the standard, higher rate. The certificate must match the vehicle exactly: VIN, make, model and invoice details. It is usually issued by the China Council for the Promotion of International Trade (CCPIT) or customs authorities. Practical tips: request the C/O before shipment, because adding it later is slow; check that your country's customs accepts the specific C/O format; and confirm with your broker whether your vehicle category qualifies for preferential rates. This single document can save you thousands in duty.

The nameplate date is the absolute time when the vehicle leaves the factory; the registration date is when the vehicle is registered with the traffic management department after sale. The difference represents the time the vehicle spent in the dealer's warehouse or logistics. If the time difference exceeds 6-8 months, the vehicle is considered a "stock vehicle," and we pay special attention to the natural aging of its rubber components.

It's extremely difficult. The security level of Chinese brand immobilizers is very high, and you must connect a specialized factory computer to the vehicle's OBD and be online with the domestic server to match it. Losing all keys usually means you need to replace the entire lock cylinder and anti-theft control module while overseas.
