It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blindly modifying the electrical systems of modern integrated circuit vehicles.

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.

Our shipping quotes are typically valid for only 7 to 14 days. If a CIF contract is signed and there are significant fluctuations in shipping costs due to war surcharges or route changes imposed by the shipping company before the vehicle is actually loaded, we will transparently provide you with the official price increase notice from the shipping company. At that point, we reserve the right to renegotiate the freight difference or allow you to change the trade terms to FOB, letting you designate your own freight forwarder for booking.
