⚠️ Chinese Manufacturer Position
Chinese manufacturers prescribe fuel tank removal and/or fuel pump access as the procedures for accessing fuel tank contents.
These manufacturers follow international standards for fuel system design and service procedures. USIFDA certified technicians adapt standard OEM procedures to these vehicles.
Chinese-Brand Vehicles and the US Market
Most Chinese passenger brands are not sold new in the United States due to tariffs, regulatory requirements, and connected-vehicle rules. USIFDA documents procedures for vehicles that are present in the US fleet or commercial channels:
- Volvo / Polestar (Geely-affiliated)—US sales; some models built in China (see Geely Group)
- Heavy equipment & commercial—separate OEM procedures (not passenger car focus)
- Imported gray-market vehicles—consult OEM service information for market of origin
The table below lists major Chinese OEMs for reference; passenger models are primarily relevant outside the US unless noted.
Major Manufacturers
| Manufacturer | Brands | Primary Focus |
|---|---|---|
| BYD | BYD | Electric vehicles, batteries |
| SAIC Motor | MG | Passenger vehicles (British heritage) |
| Great Wall Motors | GWM, Haval, Ora, Tank | SUVs, pickup trucks, EVs |
| Chery | Chery | Passenger vehicles |
| NIO | NIO | Premium electric vehicles |
| XPeng | XPeng | Electric vehicles |

Reference — Global Chinese-Brand Lineups
These brands sell primarily outside the US. If you are servicing an imported vehicle in the US, use the OEM service portal for its market of origin.
BYD (not US passenger retail)
Battery electric passenger models (Atto 3, Dolphin, Seal) cannot be misfueled. BYD also builds commercial buses and equipment used in the US through separate channels.
MG / GWM / Chery (not US passenger retail)
Gasoline, diesel, and PHEV models sold in other markets follow standard common rail / direct injection sensitivity rules—gasoline in diesel remains the critical risk for diesel variants.
✓ Electric-Only Lineups
Pure battery electric vehicles have no fuel tank and cannot be misfueled. Many Chinese OEM passenger programs are EV-heavy in their home market; US retail exposure is limited.
Gasoline and Diesel (If Present in US Fleet)
For any gasoline or diesel Chinese-brand vehicle operated in the US (import, diplomatic, or commercial fleet):
- Confirm fuel type on the door label and cap
- Do NOT start the engine after suspected gasoline in diesel
- Drain and flush per OEM service information—tank drop may be required
Service Considerations
Where a Chinese-brand vehicle is legally operated in the US, USIFDA certified technicians apply OEM-prescribed tank drain and module access procedures. Documentation availability varies by importer and OEM—consult manufacturer service information.
