CBP (22 Sep): Section 301 China exclusion conforming codes; ACE live noon 23 Sep; PSC refunds from Jul 1

U.S. CBP CSMS #69990649 (22 September 2026) gives entry-filing guidance for four Section 301 China product exclusions under HTSUS 9903.88.69 after July 1, 2026 statistical-code changes. Affected notes: 20(vvv)(i)(4)/(5)/(6) and 20(vvv)(iv)(4). New 10-digit codes include 8413.91.9039/9046/9059/9099 and 3926.90.9915/9920. ACE accepts the conforming amendment at noon on 23 September 2026. Importers who paid Section 301 duties on covered China-origin goods entered 1 July–22 September may file a Post

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.

FreightFigures: Busan truce to 10 Jan does not auto-extend 301 exclusions or China vessel port fees

FreightFigures (24 Sep 2026) argues that Treasury Secretary Scott Bessent's extension of the Busan Agreement to 10 January 2027 is diplomatic breathing room, not an automatic legal rollover of the 178 Section 301 China product exclusions (heading 9903.88.69) or the suspended Section 301 maritime fees on Chinese-linked vessels. Both still expire under their own Federal Register notices on 9 November 2026 unless USTR publishes new notices.

US Customs opens CAPE Phase 3: IEEPA tariff refunds now cover older liquidated entries for importers in court cases

Bloomberg Law (6 Oct 2026) reports that US Customs and Border Protection opened Phase 3 of its CAPE refund system on 6 October. Phase 3 lets importers of record request refunds of IEEPA tariffs on entries liquidated more than 80 days ago, but only importers that are plaintiffs in a pending Court of International Trade case. Plaintiffs that gave CBP their importer-of-record number by 30 July can file from 6 October. By mid-September CBP had sent about $122 billion in refunds, including interest,

MOFCOM: reported EU “301” tool is protectionist; China will respond if discriminatory curbs follow

China’s Ministry of Commerce (MOFCOM) said on 29 September 2026 that media reports of some EU member states drafting a joint paper urging the European Commission to accelerate a European “Section 301”-style tool and take tougher measures against China describe a typical protectionist and unilateral measure. MOFCOM warned such a tool would disrupt China–EU trade and global industrial and supply-chain stability, undermine WTO rules, and damage trust while China–EU trade and investment consultation

FreightWaves: China-linked vessel port fees still set for 10 Nov; truce to 10 Jan needs a USTR notice

FreightWaves (28 Sep 2026) reports that US Section 301 port-entry fees on China-linked and China-built vessels remain scheduled to resume on 10 November 2026, even though the broader Busan trade truce was extended to 10 January 2027. Under the existing USTR notice, the one-year pause ends at 11:59 p.m. ET on 9 November unless USTR issues another modification. As of 28 September, no such notice had been published. China's reciprocal special port fees on US-linked vessels sit on a similar clock.
