Proclamation 11052 imposes dated CBP enforcement on polysilicon stockpiling, obligating customs brokers to screen new importer-of-record status, beneficial ownership, and merchandise disposition, backed by license revocation under 19 CFR 111.53 and penalties under 19 U.S.C. 1641.
Proclamation 11052 creates a September 22 – December 4, 2026 enforcement window in which customs brokers and new importers of record must verify IOR age, ownership chains, beneficial owners, and end-use disposition of polysilicon shipments, with license suspension or penalty exposure, while no prescribed verification system is supplied.

INTERCEPT READOUT
"Customs brokers that enter Polysilicon Products and/or act as the importer of record between September 22, 2026, and December 4, 2026, are reminded of their affirmative obligation to avoid facilitating violations of this Section III... Actions by customs brokers to evade the prohibition on stockpiling Polysilicon Products may result in CBP enforcement actions."
- TARGET STATE
- Customs brokers and newly established importers of record carry a defined but unscaffolded due-diligence obligation under imminent enforcement threat; no standard verification mechanism, ownership-chain dataset, or disposition-tracking tool is prescribed, and the burden of proof rests entirely on the broker's own diligence.
