Solar & Polysilicon: The UFLPA "Kill Zone"

The solar industry is the primary target of UFLPA enforcement. Since June 2022, CBP has detained billions of dollars in solar modules, specifically targeting goods from Vietnam, Malaysia, and Thailand suspected of using **Xinjiang Polysilicon**.

The "Hoshine" Contamination

The core risk centers on **Hoshine Silicon Industry Co. Ltd**, a Xinjiang-based metallurgical silicon producer. Hoshine is on the UFLPA Entity List. If any silicon in your panel can be traced back to Hoshine—even if the panel was assembled in Hanoi—it is banned.

The Transshipment Risk

Vietnam imports 90%+ of its polysilicon and wafers from China. ChainVetter's analysis shows that many "Module Assemblers" in Vietnam are subsidiaries of Chinese firms, creating a direct liability link.

Required Evidence for Solar Importers

To release a detained solar shipment, you must provide a complete "Silicon-to-Module" map:

How ChainVetter Protects Solar Importers

We cannot map the mine (Tier 4), but we can validate the Vietnam Assembler (Tier 1). We prove:

  1. Ownership: Is the Vietnam factory owned by a sanctioned Chinese parent?
  2. Capacity: Does the factory have the physical scale to produce the GW volume claimed, or are they re-labeling finished Chinese panels?
