CBP title: GUIDANCE: Section 301 China Conforming Amendment
Action required
This message asks importers or filers to act. The position below says what to do.
What did CBP announce?
USTR amended four Section 301 China product exclusions under HTSUS 9903.88.69 to match ten-digit HTSUS changes effective July 1, 2026. The amended exclusions cover goods now under 8413.91.9039, 8413.91.9046, 8413.91.9059, 8413.91.9099, 3926.90.9915 and 3926.90.9920. ACE accepts the amended exclusions from noon on September 23, 2026. CBP says importers who paid these duties on entries from July 1 to September 22, 2026 should file a PSC for a refund.
What is Allied's position?
We apply the amended exclusions to the entries we file from noon on September 23, 2026. When we report 9903.88.69, we do not report the Section 301 China Chapter 99 number. If you imported goods under these HTSUS numbers from China since July 1, 2026, ask us to review those entries. CBP says the refund route is a PSC within the PSC period, or a protest within the protest period after liquidation.

What does the CBP message say?
The purpose of this message is to provide guidance regarding the amendment of Section 301 China product exclusions to conform with certain changes to the Harmonized Tariff Schedule of the United States (HTSUS).
BACKGROUND
On September 2, 2026, the Office of the U.S. Trade Representative (USTR) published Federal Register Notice (FRN) 91 FR 56538 (https://www.federalregister.gov/documents/2026/09/02/2026-17925/notice-of-conforming-amendments-to-product-exclusions-chinas-acts-policies-and-practices-related-to) making conforming amendments to four product exclusions. This amendment is to conform with changes to ten-digit statistical reporting categories of the HTSUS effective July 1, 2026.
The amendment found in the Annex to the Federal Register notice amends U.S. notes 20(vvv)(i)(4), 20(vvv)(i)(5), 20(vvv)(i)(6), and 20(vvv)(iv)(4) to subchapter III of chapter 99 of the HTSUS, as originally published in the Annex at 89 FR 46948 (https://www.federalregister.gov/documents/2024/05/30/2024-11904/notice-of-extension-of-certain-exclusions-chinas-acts-policies-and-practices-related-to-technology) (May 30, 2024), as amended.
The Automated Commercial Environment (ACE) functionality for the acceptance of the conforming amendment will be effective as of noon on September 23, 2026.

Importers shall not submit the corresponding Chapter 99 HTSUS number for the Section 301 China duties when HTSUS 9903.88.69 is submitted.
ADDITIONAL INFORMATION
To request a refund of Section 301 duties paid on previous imports of products granted duty exclusions by the USTR, importers may file a Post Summary Correction (PSC) if within the PSC filing timeframe. If the entry is beyond the PSC filing timeframe, importers may protest the liquidation if within the protest filing timeframe.
For example, if importers enter Chinese goods during the period July 1, 2026 through September 22, 2026, subject to the conforming amendments under HTSUS classification 9903.88.69, and pay Section 301 China duties, importers should file a PSC on or after September 23, 2026, to obtain a refund of duties paid.
Questions from the importing community concerning ACE entry rejections involving product exclusions should be referred to their CBP Client Representative. Questions related to Section 301 entry-filing requirements should be sent to the Office of Trades’ Trade Remedy branch via email to traderemedy@cbp.dhs.gov (mailto:traderemedy@cbp.dhs.gov).
