CBP issues guidance on polysilicon import ban under Proclamation 11052

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.
