On 22 September 2026, U.S. Customs and Border Protection issued CSMS #69990649 with entry-filing guidance for four Section 301 China product exclusions under HTSUS 9903.88.69. The guidance implements USTR’s 2 September 2026 Federal Register conforming amendments (2026-17925) that realigned exclusion notes after USITC changed certain 10-digit HTSUS statistical reporting categories effective 1 July 2026. Product coverage of the exclusions is meant to stay the same; the filing codes change.
CBP lists the amended notes as U.S. notes 20(vvv)(i)(4), 20(vvv)(i)(5), 20(vvv)(i)(6), and 20(vvv)(iv)(4). For notes (i)(4)/(5)/(6), goods formerly under 8413.91.9065, 8413.91.9085, or 8413.91.9096 map to 8413.91.9039, 8413.91.9046, 8413.91.9059, and 8413.91.9099 from 1 July. For note (iv)(4), goods formerly under 3926.90.9910 map to 3926.90.9915 and 3926.90.9920. ACE functionality to accept the conforming amendment is effective at noon on 23 September 2026. When 9903.88.69 is claimed, filers should not submit the corresponding Chapter 99 number for Section 301 China duties.
For refunds, CBP says importers may file a Post Summary Correction if still within PSC timing—for example China-origin goods entered 1 July through 22 September 2026 that paid Section 301 duties despite qualifying under the amended 9903.88.69 exclusions should PSC on or after 23 September. Entries past PSC timing may still be protested if within protest timing. Trade-remedy filing questions: traderemedy@cbp.dhs.gov.
