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.

Plan for roughly 25-40% on top of the vehicle price. The main items are: 1. Pre-purchase: deposit (10-30%), third-party inspection fee (100-300 USD). 2. In China: inland trucking to the port, export declaration fees. 3. Shipping: ocean freight (container 20ft usually 1,500-4,000 USD depending on destination), marine insurance (about 0.3-0.5% of car value). 4. In your country: customs duty, VAT/GST, port handling and storage, customs broker, quarantine or pre-shipment inspection if required, registration and plates. Always ask the exporter for an itemized landed-cost estimate for your specific port before paying the deposit, and confirm which Incoterm the quote is based on (FOB, CIF or DDP makes a big difference).

Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.
