Section 301 Exclusions Can Expire Before Refund Claims Do
China Section 301 exclusions are due to expire November 9, but missed claims follow entry-specific deadlines. Five code changes identify earlier imports worth reviewing.

The November 9 deadline for 178 China Section 301 exclusions does not set the deadline for recovering duties on every earlier entry. An importer that missed an exclusion may still have a correction or protest available after the exclusion expires. Another entry may need attention sooner. The answer depends on its filing and liquidation history.
That distinction matters now because five exclusions have already changed their tariff-code references. USTR made those amendments effective July 1, 2026, but CBP implemented them in two later steps, in September and October. The period between legal effect and system implementation is a specific place to look for duties paid on goods that qualified for relief.
As of November 4, the published extension ends November 9. For an importer compliance manager, the immediate job is to review earlier entries for missed exclusion claims. A decision extending the exclusions would change the treatment of later entries according to its terms. It would not, by itself, correct an earlier entry summary.
The July code changes reached ACE in two steps
The U.S. International Trade Commission changed certain ten-digit statistical reporting numbers on July 1. USTR subsequently amended the exclusion language to preserve existing product coverage, first for four exclusions on September 2, then for a fifth on October 7. These were code corrections to existing relief, not five newly excluded products.
CBP announced that ACE would accept the first four amendments from noon on September 23. Its guidance expressly addressed qualifying goods entered from July 1 through September 22 with Section 301 duties paid, directing importers toward a post-summary correction, or PSC, within the applicable filing period.
For the additional amendment, CBP set ACE acceptance at 6 p.m. on October 23. The October date must not replace September 23 in the review of the first four exclusions. Each implementation step identifies a different population worth checking. Neither date establishes that a particular importer paid excess duties.
Trace the product through its old and new numbers
The audit should join the old statistical number, its successor and the applicable exclusion note. A search limited to last year's codes can miss later entries. A search limited to the new codes can lose the product history that supports the claim.
Five exclusions affected by the July 1 code changes
As of November 4, 2026. All five use exclusion heading 9903.88.69. The table identifies records for review, not automatic eligibility. Match the amended number and any product limits in the governing exclusion note.
The fifth exclusion shows why code matching is only the beginning. The original provision covers specified iron or steel parts of metal shredders, including hammers, grates and certain protective components. The successor number does not make every article classified there eligible. Preserve the specification, invoice and exclusion description alongside the entry line.
The October amendment preserves that product description while changing the statistical number.
Under CBP's current PSC test, the ordinary deadline is 300 days after entry or 15 days before scheduled liquidation, whichever comes first. If CBP grants an extension of liquidation, the 300-day limit no longer controls, but the PSC must still be filed at least 15 days before scheduled liquidation. Qualifying entries with liquidation suspended beyond 300 days and an associated suspension basis can also remain eligible outside the ordinary period. A date filter alone is insufficient. The entry must meet the other PSC conditions, including remaining unliquidated, accepted and fully paid or revenue-free, with restrictions for CBP review, protests and reconciliation.
Once an entry has liquidated, the protest inquiry turns to 19 U.S.C. 1514(c)(3), which generally allows 180 days after liquidation or reliquidation. An importer cannot file that protest before liquidation merely because its PSC window has closed. Nor does waiting for an exclusion extension stop the statutory clock.
The review file should therefore carry the entry date, liquidation status, applicable filing deadline, exclusion match and duties actually paid. For this entry-specific Section 301 recovery, the amount claimed must follow the duties actually paid on qualifying lines. Removing the covered Section 301 duty does not establish that every other charge on the entry was incorrect.
Keep earlier claims moving while USTR decides
Start with entries in the implementation gaps, then check later entries for stale code mappings or omitted exclusion claims. The public notices establish a reason to investigate those populations. They do not establish the size of any refund, and the audit may confirm that the importer already claimed the relief correctly.
For goods entered for consumption, or withdrawn from warehouse for consumption, after the current exclusion window, the controlling development will be a new USTR action specifying its effective dates and covered products. A purchase order or arrival date alone does not establish eligibility under the existing entry-based terms.
Keep that prospective decision on the watch list while the broker resolves the earlier entries. If USTR extends the exclusions, check the new annex and CBP's implementation instructions before changing future claims. For the July code amendments, the next useful evidence is already in the importer's records, a confirmed product match, a viable correction route and an accepted filing before the entry's own deadline.
