178 China Section 301 Exclusions End November 9, and Standard Duties Return November 10

As of 26 October 2026, two Section 301 dates on China tariffs fall within days of each other. The 178 product exclusions end at 11:59 p.m. Eastern on 9 November, and standard duties apply again from 10 November unless USTR extends them. A separate suspension of Section 301 port fees and duties on China's maritime and shipbuilding sector also ends on 9 November, but USTR has proposed extending it to 9 January 2027. This post covers Section 301 only.

What Section 301 dates are scheduled for November 2026?

The table below lists every dated change in the sources reviewed for this post. The 9 November maritime end date is confirmed against the Federal Register notice of 13 November 2025. Rows marked as single source rest on one secondary publisher.

Which China product exclusions expire on 9 November 2026?

USTR extended 178 product exclusions from the China Section 301 duties through 11:59 p.m. Eastern on 9 November 2026. The extension came in a USTR notice dated 1 December 2025, FR 2025-21671, as tariffsapi.com reports. The exclusions sit under two headings.

The 164 and 14 split comes from a single source, Strix Customs Blog, dated 18 August 2026.

Do standard Section 301 duties return on 10 November?

Yes, unless USTR extends the exclusions. From 10 November 2026, the list duty applies again to products that the expiring exclusions covered, at the rate of the list each line sits on, according to tariffsapi.com. Entries filed on or after 10 November lose the exclusion and pay the standard Section 301 rate, according to Thomson Reuters.

The standard rates are 25% for Lists 1, 2 and 3 and 7.5% for List 4A, according to Strix Customs Blog. Strix says the List 4A rate was reduced from 15% under the Phase One agreement in February 2020. The rates are as of the article's date, 18 August 2026.

What happens to the maritime Section 301 suspension?

The suspension ends on 9 November 2026 unless it is extended. USTR's notice of 13 November 2025 suspended the actions in the maritime, logistics and shipbuilding investigation from 12:01 a.m. Eastern on 10 November 2025 through 11:59 p.m. Eastern on 9 November 2026, according to the Federal Register.

When the suspension ends, port fees return, according to Thomson Reuters. The chassis and port crane headings 9903.91.12 through 9903.91.16 apply from 10 November, according to tariffsapi.com.

Is the maritime suspension extension final?

No. As of 26 October 2026, the extension is a proposal. USTR has proposed suspending the responsive actions from 10 November 2026 through 9 January 2027, according to KPMG. A Federal Register notice on the proposal was scheduled for publication on 26 October, according to Global Trade Magazine.

Public comments close on 30 October 2026 at 5:00 p.m. Eastern. Until a new official notice is published, the 9 November end date stays in effect.

What else changes on 9 and 10 November?

Two non-tariff items sit on the same calendar, both from a single source. The suspension of the Bureau of Industry and Security (BIS) Affiliates Rule ends on 9 November, which would reinstate the rule automatically worldwide, according to Thomson Reuters. China's rare earth export controls begin on 10 November, with new export license requirements, according to the same article.

What should importers check before 10 November?

Thomson Reuters lists three review items for importers: recalculate port cost exposure, review affiliate screening obligations, and assess rare earth supply chain exposure. The most direct check is the entries that use headings 9903.88.69 and 9903.88.70. Those entries lose the exclusion for goods entered on or after 10 November, according to the sources above.

What's still unclear?

• Expiry wording differs. The USTR notice, as quoted by tariffsapi.com, ends the exclusions at 11:59 p.m. Eastern on 9 November. Thomson Reuters says the exclusions expire on 10 November. Both point to the same cutoff: 9 November is the last covered day, and 10 November is the first day duties apply.
• Time zone wording differs. The Federal Register notice uses Eastern Standard Time, and the exclusions notice uses eastern daylight time. Both describe 11:59 p.m. Eastern on 9 November.
• The maritime extension is a proposal. The 9 January 2027 date is not final, and the comment period is still open.
• No further extension was reported. As of 19 October 2026, the tariffsapi.com article reported no further extension of the 178 exclusions. USTR's decision on resuming the maritime action is due before 10 November.
• Single-source figures. The 164 and 14 split, the 25% and 7.5% rates, the BIS Affiliates Rule date and the rare earth date each rest on one secondary publisher. Confirm them against the USTR and BIS documents before acting on them.
