In 2025, DHS added **Aluminum** and **Steel** to the UFLPA priority enforcement list. Xinjiang is a major hub for smelting due to cheap coal power. Vietnamese extruders often import billets and ingots from Xinjiang, contaminating the supply chain for auto parts and construction materials.
Entities like **Xinjiang Production and Construction Corps (XPCC)** are heavily involved in metal production. Any steel or aluminum originating from XPCC-affiliated smelters is banned.
To avoid tariffs (Section 232), Chinese metal is shipped to Vietnam for "minor processing." CBP requires proof that **Substantial Transformation** occurred in Vietnam.
Smelting aluminum requires massive amounts of electricity. A "Factory" in Vietnam with low capital and a small electrical footprint cannot possibly be smelting raw ore. ChainVetter verifies the industrial capacity to prove if a supplier is a real foundry or just a warehouse.
ChainVetter provides the **Corporate Lineage Report** to prove your Vietnamese metal supplier is independent and not a subsidiary of a Xinjiang aluminum giant.
