🔒SCOTUS Tariff Gamble | Retroactive 232 Shock | Quartz Quotas Incoming
Edition 20 - Week 22/2026 Period Covered: 19 May – 25 May 2026. Published: 26 May 2026.
The Customs Watch USASummary: The U.S. trade landscape is facing unprecedented turbulence as retroactive Section 232 corrections, impending Section 301 Supreme Court reviews, and heavy antidumping duties redefine corporate risk. Importers must shift from static sourcing models to agile boardroom-level compliance to protect their financial margins. |
How will the CAPE Declaration update affect your IEEPA customs refunds?
The U.S. Customs and Border Protection (CBP) recently revised its International Emergency Economic Powers Act (IEEPA) refund framework, introducing vital mechanics for CAPE Declarations. A critical, self-contained aspect of this update is that, while unliquidated and Phase 1 entries will have IEEPA tariffs removed, the recalculation process will handle all underlying non-IEEPA duties, taxes, and fees. If your prior payments fall short of the newly calculated non-IEEPA duty liability, CBP will not hesitate to issue a bill for the difference. Importers must systematically reconcile their total duty positions prior to filing to prevent triggering unexpected underpayment bills or having disbursements net-offset against separate outstanding record debts.
For a deeper dive into IEEPA refunds and the CAPE process, we recommend you read the current edition of The Customs Watch USA, where we will analyze what really happened, what businesses are concerned and who is affected in your company, what you may wish to do and provide you with links to find out more.

Why are final AD/CVD duties on Asian and Russian chemical imports skyrocketing?
Recent trade investigations have concluded with highly punitive final determinations, meaning rates are legally locked and cannot be adjusted downward before an official order takes effect. For instance, on May 20, 2026, the Department of Commerce finalized a 109.10% Countervailing Duty (CVD) rate on all Russian-origin unwrought palladium under case C-821-841, driven by Adverse Facts Available (AFA) designations due to non-cooperation. Concurrently, on May 21, 2026, final Antidumping (AD) margins ranging from 65.72% to 155.42% were locked against South Korean monomers and oligomers under case A-580-921, with primary suppliers such as Miwon and Kukdo hit with the maximum 155.42% punitive AFA rate. Because the "All Others" categories are pinned at high minimum thresholds (109.10% for Russia and 65.72% for Korea), importers must immediately update their landed-cost accounting models to reflect these significant financial exposures.
