Four product lines — vehicles, energy storage, farm machinery and engines — from long-established Chongqing manufacturing bases, exported through one channel under one QC standard.
- One mixed container — vehicles, batteries, machines and spares ship together; 220+ SKUs on one loading plan cuts freight and admin cost per line.
- One QC & export standard — factory specification sheet and certification status attach to every quotation, answered within 24 hours.
- Field-proven flagship tech — immersion-cooled storage in oilfield service since 2022 at 8.1% of diesel energy cost.
- SKD / CKD routes — local-assembly programs ready where import policy requires them.
How to Choose
- Duty before displacement — tricycle duty, rider duty and two-wheel commuter duty stress different parts of the engine; pick the family, then the model code.
- Assembly strategy — complete engines for service parts; SKD/CKD kits where local-content programs reward local assembly.
- Service-parts horizon — engine programs are recurring supply; model coverage stays stable across years.
Where this line sits
