CBP issued updated guidance on October 22 for five China Section 301 product exclusions affected by tariff-code changes. Additional ACE filing functionality was scheduled for 6 p.m. on October 23, and the underlying amendments apply to qualifying entries from July 1.

For affected importers, that creates a targeted reason to review past duty payments. It is not a refund entitlement for everyone importing from China, and it does not remove unrelated tariff layers.

What Actually Changed

CBP's bulletin ties the changes to revisions in ten-digit statistical reporting categories, identifying five affected exclusion notes under heading 9903.88.69.

The listed changes involve specified reporting numbers in headings 8413, 3926, and 8479. Treat those headings as a screening aid rather than proof your merchandise qualifies. The product still has to satisfy the applicable exclusion description and entry conditions.

The October 7 USTR notice explains that its amendment maintains pre-existing product coverage, substituting reporting number 8479.90.9591 for the relevant period beginning July 1.

This is classification maintenance with possible cash consequences. A statistical code changing does not mean the product lost its exclusion, but the filing has to reflect the correct treatment.

Start With Entry Records, Not Supplier Invoices

Ask your broker to identify entries since July 1 using the affected old or new reporting numbers. Then compare product descriptions, exclusion language, declared value, and the Section 301 duty actually paid.

Work from the customs entry rather than a supplier invoice marked “tariffs included.” You need to know which company was importer of record and which duty lines appeared on the filing.

C.H. Robinson's October 28 advisory independently flags the operational issue and the possibility of corrections or refunds on qualifying entries. It does not promise eligibility for every shipment inside those broad product headings.

Build a worksheet linking each candidate entry to its purchase order and SKU. Record your broker's conclusion and the supporting exclusion language, including the entries that do not qualify.

That negative result has value. It stops your team re-examining the same ineligible entry every time another refund headline appears.

Two Recovery Routes, Different Deadlines

CBP says importers can request removal of Section 301 duties through a Post Summary Correction while within the applicable filing timeframe. Where that window has closed, a protest may be possible within the relevant protest timeframe.

Ask your broker to determine each entry's status and deadline. Do not assume one calendar reminder covers every shipment, or that a refund process starts automatically because ACE now accepts the amended code.

This is separate from the IEEPA refund process covered in the CAPE tariff-refund portal. That is a different duty program, and those filing instructions do not apply here.

Keep the distinction in your accounting. Duties paid, amounts potentially recoverable, claims filed, and cash received are four different figures.

Estimate Without Booking It

Use the actual Section 301 line item when estimating a possible refund. Do not multiply a total invoice by a tariff percentage borrowed from another product category.

If a broker confirms $2,400 of eligible duty overpayments and charges $300 to prepare the corrections, the potential net recovery is $2,100 before other costs. Neither figure predicts your result or establishes that CBP will approve the filing.

Separate past-entry recovery from future import pricing too. The October bulletin does not extend the duration of the exclusions, so check the currently applicable USTR notice before budgeting relief on the next shipment.

Send your broker a specific request this week: identify affected entries, confirm product eligibility, state the filing route and deadline, and quote the work.

The useful outcome is a documented entry-by-entry decision followed by a tracked filing where justified, not an unsupported refund receivable sitting in your books.
