Measures To Restrict Stockpiling of Polysilicon and Polysilicon Derivatives Under Proclamation 11052
What happened
On August 6, 2026, the President issued Proclamation 11052, directing the Secretary of Commerce to restrict imports by companies stockpiling polysilicon and its derivatives. The Bureau of Industry and Security (BIS) issued a temporary final rule (TFR) to monitor existing companies for stockpiling, limit new importers' ability to stockpile, and prohibit imports for stockpiling companies. The TFR also sets a process for waivers and imposes import limits on new importers registering on or after August 6, 2026, ahead of import adjustments effective December 4, 2026.
Why it matters
This rule prevents companies from circumventing future import adjustments by accumulating polysilicon and its derivatives before new regulations take effect. It aims to ensure an orderly transition for import policies concerning these materials. Companies engaged in or planning to engage in stockpiling could face import prohibitions.
Who it affects
- ›Existing companies importing polysilicon products.
- ›Newly established polysilicon product importers.
- ›Companies attempting to stockpile polysilicon products.
