The forced-labor Section 301 action, the expired Section 122 surcharge and the Canada Section 338 duties have different effective dates, country and product scopes, Chapter 99 lines, exclusions and liquidation histories. Some entries can carry more than one covered tariff. Others carry covered and untouched duties on the same summary. A single reversal keyed to an importer or date range would remove too much in some cases and find nothing in others.
The right implementation model is three authority-specific refund tracks feeding one entry-line refund ledger. That ledger, not a generic claims portal, is the control that would let CBP remove each covered duty once while preserving every duty the bill leaves in place.
The proposal is not law. Until enacted text and CBP instructions exist, current payment, liquidation and protest rules continue to apply.
The bill closes the legal route that earlier proposals left open
The End Trump’s Tariff Tax Act bill text published by the United States Senate Democratic Caucus contains its own repayment machinery. Section 5 says that, notwithstanding 19 U.S.C. 1514 or any other law, CBP must automatically refund covered duties paid by each importer. It requires interest, sets a 30-day deadline, orders reliquidation of entries already liquidated, covers warehouse withdrawals, and bars CBP from requiring a refund request or documentation. That is a material change from the proposal examined in the earlier Traverse analysis of the BAD DEAL Act, which ordered a result without supplying an automatic CBP route.
That language is consequential. The Office of the Law Revision Counsel 19 U.S.C. 1514 customs finality rule ordinarily makes liquidation final unless a statutory exception or timely protest applies. The new text is drafted to cross that barrier. It should not be analyzed as another repeal bill that leaves final entries without a recovery instruction.
The United States Senate Democratic Caucus September 1 announcement of the End Trump’s Tariff Tax Act describes the measure as introduced. The linked legislative file still displays a blank bill number and committee line. Its exact legislative identity and any later revision should be confirmed before relying on the sponsor text as the operative version.
One refund window does not describe three collection calendars
The bill assigns one deadline, but it starts three different eligibility windows. Those windows do not match the official collection calendars.
| Tariff action | Duty applicability to entries or withdrawals | Bill’s collection-based refund window | First implementation exception |
|---|
| Forced-labor Section 301 action | General coverage began July 24, with a narrow in-transit exception | July 23 through enactment | The refund window starts one day before general liability began |
| Section 122 surcharge | Stopped applying July 24 after the 150-day period | August 1 through enactment | Routine payment for an earlier entry can fall after the window opens |
| Canada Section 338 duties | Began August 22 after a three-day suspension | August 1 through enactment | The refund window starts 21 days before collection began |
The dates come from the Office of the U.S. Trade Representative forced-labor Section 301 final action at 91 Fed. Reg. 47318, White House Proclamation 11012 temporary Section 122 import surcharge, and White House Proclamation 11056 suspension of Canada Section 338 duties until August 22.
The Section 122 line exposes the difference between tariff applicability and payment. Under the Electronic Code of Federal Regulations 19 C.F.R. 142.12 entry-summary and estimated-duty deadline, an entry summary and estimated duties can follow entry by as many as 10 working days. The U.S. Customs and Border Protection Periodic Monthly Statement payment guide allows eligible entries to be paid on the 15th working day of the following month. A July Section 122 entry could therefore generate a routine August payment even though the surcharge stopped applying to new entries on July 24.
Two otherwise identical July entries could land on opposite sides of the bill’s August 1 refund boundary because one was paid on a daily statement and the other through Periodic Monthly Statement. Unless implementing text defines “collected,” payment method could decide statutory eligibility.
The word “collected” introduces a broader date question. At entry, an importer generally deposits estimated duties. Liquidation fixes the final amount later. The bill does not say whether “collected” means the entry or warehouse-withdrawal date, the entry-summary filing date, the daily or monthly-statement payment date, the deposit posting date, the liquidation date, or another collection event. A defensible system would preserve all of them until implementing instructions choose the controlling event.
Why this is new: the legal route is complete, but the calculation is not
The three tariff actions do not share one population of HTS lines.
The forced-labor Section 301 action applies country-specific additional rates across 60 economies, with product exclusions and in-transit treatment. The U.S. Customs and Border Protection CSMS 69326983 forced-labor Section 301 filing instructions tell filers how to report that action through its Chapter 99 structure.
The Section 338 action is narrower. It covers specified Canadian product lines under three proclamations responding to discrimination in alcoholic beverages, dairy and motor vehicles, with exclusions and separate Chapter 99 headings. The U.S. Customs and Border Protection CSMS 69606660 Canada Section 338 filing instructions also say those duties apply in addition to other duties unless an instruction provides otherwise.
Each authority-specific track needs four controls inside the 30-day command:
- Identify the exact covered Chapter 99 line and the amount deposited under that authority.
- Remove only that line while retaining base duty, unaffected Section 301 duties, Section 232 duties, antidumping and countervailing duties, taxes and fees.
- Net any prior post-summary correction, protest decision, reliquidation, refund or drawback affecting the same amount.
- Reconcile overlapping covered lines so a qualifying Canadian entry receives each authorized reversal once, not one blended estimate and not a duplicate payment.
A Canadian product can fall inside both the 60-economy forced-labor action and the product-specific Section 338 action. The bill would cancel both covered additions. It would not cancel every other assessment on that entry. The task is a line-by-line rollback, not a blanket rate cut.
The current IEEPA refund portal is not a ready-made front end for this job. The U.S. Customs and Border Protection CAPE Phase 1 tariff refund claim instructions ask an importer or broker to submit a claim and declaration for a defined IEEPA entry population. In the Freestyle World v. U.S. Customs and Border Protection ECF No. 38 declaration on CAPE Phase 3, CBP told the Court of International Trade that planned Phase 3 validations are intended to prevent non-IEEPA duty adjustments during court-ordered reliquidation. The CAPE Phase 3 CSMS 68340863 non-IEEPA duty controls analysis examined that negative control. Schumer’s bill would order the removal of three named non-IEEPA duties. Parts of the existing recalculation machinery may be reusable, but the intake logic and authority filters would have to run in the opposite direction.
Liquidated and unliquidated entries need different interest treatment
The bill expressly says “with interest.” That establishes a stronger entitlement than special refund legislation that says nothing about interest. It does not supply a rate, an accrual cutoff, or a complete calculation rule for every entry state.
For an entry already liquidated, Section 5 requires reliquidation. That gives CBP a new final calculation from which to identify the excess deposit and compute interest.
For an entry still unliquidated, Section 5 still orders payment within 30 days. The Electronic Code of Federal Regulations 19 C.F.R. 24.36 customs refund interest rule ordinarily allows a pre-liquidation refund of principal, then computes interest when the entry is later liquidated or reliquidated. The bill instead appears to require principal and interest within the same 30-day period without separately ordering early liquidation of those entries.
That conflict does not defeat the refund. It requires an instruction. CBP and Treasury would need to state the rate, beginning and ending dates, and treatment of a later liquidation adjustment. The system also needs a rule for an entry that changes status while the 30-day run is underway.
The priority and payment layers sit outside the duty calculation
The bill tells CBP to prioritize small businesses to the extent practicable. It defines small business through 15 U.S.C. 632, then forbids CBP from requiring refund documentation.
The Small Business Administration Table of Small Business Size Standards at 13 C.F.R. 121.201 shows why this cannot be inferred from an importer’s name. The applicable threshold varies by industry and usually depends on average receipts or employee count, including subsidiaries and affiliates. U.S. Customs and Border Protection Form 5106 importer identity record can include an optional NAICS code and related-business identifiers, but it does not establish all of the facts needed for an SBA size determination.
CBP would need an authoritative interagency match, a lawful certification method, or an instruction that the priority is impracticable where status cannot be verified from existing records. That classification should rank otherwise valid refunds. It should not alter the authority-specific duty calculation.
Payment is another layer. Since February 6, CBP refunds have generally moved through ACH. The Federal Register electronic customs refund rule at 91 Fed. Reg. 21 and U.S. Customs and Border Protection ACH refund enrollment instructions require importers receiving electronic refunds to maintain an ACE Portal account and valid banking authorization, subject to limited exceptions.
U.S. Customs and Border Protection CSMS 69570464 rejected-refund warning told importers and brokers on August 18 that missing ACH enrollment can delay or reject payment. “Automatic” can describe entitlement and CBP initiation without guaranteeing that every transfer reaches a bank account by day 30.
What customs compliance managers should do
Build one **multi-authority refund ledger** at the entry and HTS-line level. Do not book a receivable from an unnumbered proposal, and do not let the project replace current protest or liquidation controls.
Each row should retain:
- importer of record number and legal payee name
- entry or warehouse-withdrawal date
- actual deposit or collection posting date
- covered authority and Chapter 99 line
- principal paid under that line
- liquidation and protest status
- prior post-summary correction, reliquidation, drawback or refund
- proposed interest basis and unresolved interest fields
- ACH Refund Authorization status and last validation date
- exception code for a date, authority, identity or duplicate-payment conflict
Run three authority-specific eligibility calculations into that ledger. A shared exception queue can then resolve entries that overlap, lack a controlling date, have changed liquidation status, or cannot accept electronic payment.
The ledger has one job: prove that each covered duty was removed once and every uncovered assessment was preserved. It should not attempt to prove that Congress will enact the proposal.
Benchmarks to watch
The operating answer changes if the public record supplies any of the following:
- a numbered bill and committee referral with revised text
- a definition of “collected” and the date that controls eligibility
- an authority-by-authority Chapter 99 mapping and exception hierarchy
- rules for interest on still-unliquidated entries
- netting rules for prior refunds, drawback and post-entry changes
- an SBA status source keyed to importer numbers
- instructions reconciling no-document treatment with ACH enrollment and failed payments
- evidence that the Section 122 window contains assessments after August 1
The most important artifact will be the first CBP implementation notice or data specification. It will show whether the agency treats the bill as three calculation tracks or tries to force three authorities through one batch rule.
Caveats
This analysis reads the bill text published by its Senate sponsor and the official tariff and payment records available on September 1, 2026. The sponsor file does not yet display a bill number. A later introduced version, committee amendment, enacted text or implementation rule could change the dates, definitions and sequencing.
The proposal’s Section 301 clause targets the 2026 forced-labor action described in 91 Fed. Reg. 47318. It does not repeal Section 301 itself. Its Section 122 and Section 338 clauses would repeal those statutory authorities.
The bill would pay importers. It contains no rule requiring an importer to pass a refund through to customers. It also does not make the three tariff actions inactive before enactment.
The 30-day deadline is legally simple and computationally demanding. Congress can put three tariffs in one sentence. CBP still has to unwind them one line at a time.
