Practical application
Implementation records should capture assembly type, source vehicle, condition, whether remanufacturing conditions are met, recipient enterprise, transfer evidence, and whether non-remanufacturable assemblies were sold as scrap metal for smelting raw material.
Minespider commentary
For auto-circularity evidence, five-major-assemblies records connect vehicle dismantling to high-value component reuse/remanufacturing pathways while preserving China’s legal boundaries.
Common confusions
- Treating all parts as five major assemblies.
- Making remanufacturing claims without condition and recipient-enterprise evidence.
- Using the English label without preserving the official Chinese term.
