    U.S. Commerce temporary final rule restricts polysilicon stockpiling ahead of Section 232 import adjustments

    The U.S. Department of Commerce issued a temporary final rule restricting stockpiling of polysilicon and its derivatives ahead of Section 232 import adjustments taking effect on Dec. 4, 2026, covering imports during the transition period from Sept. 22 to Dec. 3. The rule followed trade data showing a sharp increase in polysilicon imports after the Section 232 measures were released in early August. One market participant said the rule could curb China-origin wafers, cells and modules entering through circumvention channels involving smaller traders and companies, with limited direct impact on global polysilicon demand.

    BIS issues temporary final rule on polysilicon stockpiling under Proclamation 11052

    BIS issued a temporary final rule, effective September 22, 2026 through December 3, 2026, setting the criteria and process it will use to monitor existing companies for evidence of stockpiling polysilicon and polysilicon derivatives ahead of import adjustments effective December 4, 2026 under Proclamation 11052. The rule limits a newly established importer's ability to stockpile, imposes import limitations on new importers that register with CBP on or after August 6, 2026, and subjects companies found to be stockpiling to an import prohibition if necessary. It also establishes the process for such companies to obtain a waiver from any import prohibitions imposed under the rule.

    Why it matters: Importers of polysilicon and polysilicon derivatives, including new importers that registered with CBP on or after August 6, 2026, face stockpiling monitoring, import limitations and possible import prohibitions through December 3, 2026.
