Create a vehicle identity sheet
Record the VIN, original market, production information, DM-i or EV powertrain and relevant equipment. Keep supporting registration or manufacturer records available, with personal information removed where unnecessary. The model identity guide explains why overseas naming must not be treated as automatic equivalence. A translated sales name can help communication, but it should not be the only lookup field. For a component inquiry, include the system involved and the reason for replacement so the supplier does not select a part solely from an incomplete headline.
Document the installed component
Ask a qualified workshop to record the existing part reference, connector arrangement and relevant markings where safely accessible. Photographs should show context and identifying detail, not only a close crop that could belong to another assembly. Do not dismantle high-voltage or safety equipment simply to obtain a number. Where the fitted part may already be an incorrect replacement, tell the supplier; copying it blindly could repeat the error. Compare the component evidence with a VIN-based catalogue or supported service lookup rather than allowing either source to stand alone when they conflict.
Keep DM-i and EV applications separate
The powertrain comparison is a starting point, not a parts interchangeability list. Cooling, electrical, drivetrain and other components may have different applications. Even a visually similar service item can have a different specification or revision. Ask the supplier to confirm the exact application and any supersession in writing. Do not accept a broad statement that all BYD parts are shared. A part that bolts into place may still be inappropriate for the system, software or operating conditions of the selected vehicle.
Check revision and associated work
A replacement reference may supersede an older number or require related components, coding, adaptation or calibration. Ask what the complete repair involves and which information the receiving workshop needs. For glass and camera-related work, consult the windscreen repair assessment. For keys, review the access and account guide. Do not assume that purchasing hardware completes the job. Establish destination capability before ordering a component that cannot be commissioned locally, and distinguish confirmed requirements from a seller's general advice.
Evaluate the supplier and return terms
Request a written quotation listing the part number, condition, quantity, declared application and what is included. Clarify whether the item is new, remanufactured or used and what evidence supports that description. Agree how a mismatch or shipping damage will be handled before payment. Avoid publishing VIN and personal documents in public listings; provide necessary information through a suitable private channel. For safety-critical components, prioritise traceability and qualified installation rather than choosing purely by price. A low purchase figure is not a saving if the item cannot be verified or returned.
Budget for a complete cross-border repair
Include transport, applicable destination charges, installation and required commissioning in the cost comparison. Ask about realistic availability and lead time without treating an unverified stock claim as a commitment. Some components have special transport or handling requirements that need a qualified logistics provider. The landed cost guide provides a broader framework, but a parts shipment needs its own scope. If downtime matters, identify a local workshop and scheduling plan before dispatch. Do not describe a car as fully supported merely because one supplier can quote a common consumable.
Close the loop after installation
Retain the supplied reference, invoice, installation record and any required test or calibration result. Compare the received item with the approved quotation before installation. If the part differs, stop and obtain clarification rather than modifying it to fit. Record the vehicle identity on the service file so future maintenance can distinguish the original equipment from later changes. During the first local service, build a practical list of routine items and support routes. Reliable parts planning is a repeatable identification process, not a promise that every similarly named model shares components.
Buyer checklist
- Record VIN, market and DM-i or EV identity.
- Confirm the component number and installed context.
- Verify revisions and commissioning requirements.
- Agree traceability, returns and complete repair cost.
Questions and answers
Can I use an overseas Sealion 6 catalogue for a Sealion 06?
Not as proof of fit. Confirm the exact vehicle and component through a supported VIN-based lookup; similar model names do not establish interchangeability.
Is a matching photograph sufficient to order a part?
No. Part references, application, revisions and any installation requirements matter. Use photographs as supporting evidence rather than the sole identification method.
Reference information
Use the applicable market and year documentation for equipment and operating limits. The references have their own market and publication scope; they do not establish the condition, fitted equipment or destination approval of an individual vehicle.
