EPC Catalogs for Chinese Car Brands: Chery, Geely, BYD, GWM

The main Chinese EPC systems

The headline brands and the sub-brands their catalogs cover:

• Chery EPC: Chery, plus Exeed, Omoda, Jaecoo and Jetour
• Geely EPC: the Geely range, with links to its wider group
• GWM EPC: Great Wall, Haval, ORA, Tank and Wey
• BYD: the fast-growing EV maker, now sold in dozens of markets
• SAIC EPC: MG and related models (not available on VINsearch)

Why these catalogs feel different

Model cycles move quickly, sub-brands multiply, and the same platform can appear under several names across markets. That makes VIN-level identification more important here than almost anywhere, because matching by badge alone is unreliable when one car wears different names in different countries.

Why coverage is a competitive edge

As these brands' parc grows, the workshops that can already identify their parts accurately win the service work. Many independents still turn these cars away or guess. Online access removes the barrier of sourcing each maker's catalog separately, so you can quote a Chery or a BYD as confidently as a Golf.

Find the group before you look for the badge

This is the mistake that wastes the most time. European and Japanese habits say one badge means one catalog, and the Chinese groups do not work that way.

Omoda, Jaecoo and Exeed are Chery Group brands running on Chery numbering. Haval, Tank, Ora and Wey belong to Great Wall and share GWM data. Geely spans several marques on group data again. A workshop searching for an "Omoda catalog" as if it were an independent manufacturer finds nothing and concludes the data does not exist, while the part sits waiting under the group.

The numbering is easier than it looks

Many Chinese numbers follow the national assembly-group convention, where the leading digits identify the system rather than the model. 3501 is the brake group, 1109 is air intake, 3801 belongs to instrumentation. A Great Wall number such as 3501100-K00 announces itself as a brake component before you know anything else about the car.

Chery puts the platform first instead, so T11-3501080 reads as platform then group. BYD prefixes with the brand. Once you can read those leading digits, a supplier quote either matches the part you asked for or it visibly does not, which is the same fast check a VAG number gives you through its middle block.

The EV angle

Several Chinese leaders are EV-first, BYD above all. That shifts the critical assemblies to the high-voltage system: battery modules, power electronics and thermal loops. A proper EPC documents those groups, which generic aftermarket lookups rarely do.

BYD is worth singling out because it manufactures its own cells and much of its own electronics rather than assembling bought-in modules. The aftermarket alternatives that exist for a fifteen-year-old diesel simply have not appeared here yet, so the group catalog is usually the only route to a high-voltage part rather than the preferred one.

Why the badge is not the catalog

Chinese groups launch sub-brands faster than catalogs are renamed, and the export badge frequently differs from the domestic one. Omoda and Jaecoo are Chery brands; Denza sits under BYD; Wuling and Baojun are SAIC-GM-Wuling. A workshop looking for an "Omoda catalog" is looking for the Chery data, and searching the badge finds nothing.

The practical rule is the same as everywhere else: identify by VIN and let the catalog tell you which group the car belongs to. The badge on the grille is marketing; the VIN is the build.

What is genuinely different

Two things. First, export specifications diverge more sharply from domestic ones than they do for established European marques — a model sold in Europe may carry different lighting, restraint and emissions hardware from the same nameplate at home, and the parts follow the market. Second, model cycles are short and mid-cycle changes frequent, so build date matters more than usual when the catalog offers two variants.

Both push in the same direction: resolve the VIN, read the build, and treat model-name matching as unreliable rather than merely imprecise.

Electric models

A large share of Chinese exports are electric, which changes which assembly groups exist rather than how you navigate them. The high-voltage pack, drive unit and charging hardware have their own structure, and several components are married to the vehicle and need coding after fitting. How EV parts work in an EPC covers that ground in full.
