US Customs and Border Protection (CBP) has issued guidance on Commerce’s new measures to prevent stockpiling of polysilicon and certain polysilicon derivative products ahead of the December 4, 2026, implementation of the new Section 232 measures.
Under the temporary rules, Commerce may notify CBP that an importer of record (IOR) is importing covered products in volumes substantially above its historical averages. New IORs registered with CBP on or after August 6, 2026, are also subject to specific weekly quantity limits. If Commerce determines that an importer has exceeded the applicable limits, CBP may prohibit that IOR from making further entries of certain covered polysilicon products through December 4.
Importers subject to a prohibition may move the affected goods to a bonded warehouse, but the merchandise cannot be entered for consumption before December 4. Importers may also apply to Commerce for a waiver of the prohibition.
