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.

Fake or recycled inspection reports are a real risk. Verify authenticity before wiring the balance payment. First, match the VIN: the report must show the full VIN, and the photos must include close-ups of the VIN plate on the chassis and the windshield tag. Ask for a live video call where the inspector walks to the car, shows the VIN tag, and then pans across the dashboard, odometer, and any defects noted in the report—on the same call. Check metadata: ask for original photos rather than screenshots. Files sent via WeChat often strip EXIF, so request the inspector to email originals or use a cloud link where timestamps and GPS data are visible. Cross-verify details: the odometer reading in the video should match the report exactly, and paint-thickness readings should be reproducible—ask the inspector to re-measure 2-3 spots live. Use a known inspection company rather than one recommended solely by the seller, and pay the inspector directly. An independent inspector has no incentive to hide defects.

Customs clearance at destination is usually handled by a licensed customs broker, not the exporter. You can hire one yourself or use a broker recommended by your shipping agent. The typical flow: your broker files the import declaration using the documents the exporter must provide — the commercial invoice, packing list, bill of lading, and the certificate of origin. Depending on your country's rules, you will also need to pay import duty, VAT or sales tax, and any excise or environmental levies before the car is released. Things that commonly delay clearance: mismatched VIN numbers between documents, missing pre-shipment inspection certificates (required in some African and Middle Eastern countries), or non-compliance with your country's used-car import age limits. Budget 3–10 working days for clearance after the vessel arrives, plus storage fees if documents are incomplete. Tip: send all documents to your broker for review before the ship departs China — fixing errors at origin is much cheaper than demurrage at destination.
