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.

CBP states in CSMS # 69994928 that, under Commerce's Temporary Final Rule implementing Proclamation 11052 (91 FR 51975), an importer of record that Commerce determines is importing polysilicon products in volumes substantially greater than its historic averages, or that a new importer of record is exceeding applicable weekly quantity limits, is prohibited from making further entries of certain polysilicon products until December 4, 2026. The goods may be moved to a bonded warehouse but may not be entered for consumption before that date. Affected importers may apply to Commerce to waive the prohibition.

CITT rescinds order on photovoltaic modules and laminates from China

The Canadian International Trade Tribunal rescinded its order concerning photovoltaic modules and laminates originating in or exported from China under subsection 76.03(2) and subparagraph 76.03(12)(a)(iii) of the Special Import Measures Act, so anti-dumping and countervailing duties no longer apply to new releases of covered goods. The CBSA will automatically refund these duties on eligible goods released on or after March 25, 2026, and any outstanding re-determination process for those goods will be terminated. Goods released before March 25, 2026 are not eligible for a refund, and assessments and reassessments relating to those earlier releases will continue.
