2.Customs relations：AEO Advanced Certification at major ports (Shanghai,Shenzhen);

3.Technical Team: Equipped with customs experts familiar with automotive parts (it is recommended to request proof of personnel qualifications);

4.With the increase in the penetration rate of electric vehicles,the import demand for the three - electric systems (battery,motor,electronic control) and charging pile components has surged,but they face more stringent technical barriers: : Adopt a fixed service fee + tiered pricing model (e.g.single container agency fee ranging from 3000 to 5000 yuan).

V.Future Trends and Suggestions

With theThe technical requirements for automotive ignition systems are being upgraded (e.g.specialized spark plugs for hydrogen-fueled engines).It is recommended that import enterprises:
