Why a BYD needs the catalogue more than most cars
BYD builds its own batteries, its own motors and much of its own electronics, so a large share of the parts list has no aftermarket equivalent at all. There is no cross-reference to fall back on: the genuine number from the manufacturer catalogue is the only number.
Export specifications also diverge sharply from the domestic Chinese ones. Lighting, restraint systems, charging hardware and emissions-adjacent components are specified per destination market, and the model cycles are short enough that build date decides between variants more often than model year does. Both are in the build record the VIN resolves.
The badges BYD sits behind
Denza is BYD's premium line and resolves through the same data. Yangwang and Fangchengbao are newer sub-brands on the same group platforms. A workshop searching the badge on the grille will often find nothing; searching the VIN finds the car.
The Atto 3, Dolphin, Seal, Seal U, Han and Tang are the nameplates most export markets see, and all of them resolve by VIN in the same catalogue.
High-voltage work and what the catalogue documents
The Blade battery pack is catalogued as an assembly with its own modules, contactors, service disconnect, cooling plates and — importantly — its single-use pack seals and fasteners, which are exactly the parts a job stops for when they were not on the order.
Drive unit, onboard charger and the multi-circuit thermal management each carry their own assembly groups. Several of those components are married to the vehicle and need coding after fitting; the catalogue identifies the part, and the pairing step needs tooling that is worth establishing before the order goes out rather than after it arrives.

Frequently asked questions
Does the BYD catalogue cover Denza?
Yes. Denza is BYD's premium line and resolves through the same data, as do the newer group sub-brands. The VIN decides which, not the badge.
Are aftermarket BYD parts available?
For wear items in some markets, yes; for the high-voltage system, drive unit and most electronics, no — BYD builds them in-house and there is no aftermarket equivalent to cross-reference. The genuine number is the only number.
Why does my BYD not match the model year listing?
Export builds differ from domestic ones and BYD revises frequently, so build date separates variants more often than model year does. Both are in the build record, which is why identification starts at the VIN.
