U.S. tariff changes coming from November 2026 to February 2027
Four dated tariff changes fall between November 9, 2026 and February 9, 2027, and two of them could still be extended. China Section 301 exclusions end, the maritime Section 301 suspension ends, polysilicon gets a new Section 232 duty, and a 25% duty starts on some drone components.
Last verified against the Federal Register as of October 19, 2026. Dates move: if a notice published after that day changes one, the notice wins. See our changelog for what we have shipped.
Each date below is printed in a published notice or proclamation. For each one we quote the sentence that sets it, say what it reaches, and say whether it could still move. USTR has extended the November 9 exclusions before, and its notice on the November 10 suspension says it may continue the suspension, so treat those two as scheduled rather than settled. Four comment deadlines in the same window follow the calendar.
The calendar
| Date | What happens |
|---|---|
| Nov 9, 2026, 11:59 p.m. ET | 178 China Section 301 product exclusions end. Could it move? Yes. USTR has extended this set before. |
| Nov 10, 2026 | Suspension of the Section 301 maritime action ends; the chassis and port crane headings apply. Could it move? Yes. USTR said it would decide before the date. |
| Dec 4, 2026, 12:01 a.m. ET | Section 232 polysilicon: minimum import price program and an additional 15% duty start. Could it move? Partly. Commerce can adjust for some partners. |
| Feb 9, 2027, 12:01 a.m. ET | A 25% Section 232 duty starts on the drone components in Annex III. Could it move? Partly. Lower rates can apply under clauses (4) and (6). |
A temporary polysilicon anti-stockpiling rule also ends on December 3. It sets no duty; see the polysilicon section below.
And the comment deadlines:
| Deadline | Docket |
|---|---|
| November 9, 2026 | U.S. International Trade Commission, implementing Section 338(g) (FR 2026-18385) |
| November 9, 2026 | USTR, the EU carbon border adjustment mechanism (FR 2026-20615) |

| January 12, 2027, 11:59 p.m. EST | USTR, the operation of USMCA, and requests to appear at the hearing (FR 2026-20341) |
November 9: 178 China Section 301 exclusions end
USTR’s notice of December 1, 2025 (FR 2025-21671) extended a set of 178 exclusions from the China Section 301 duties “through 11:59 p.m. eastern daylight time on November 9, 2026.” They are the exclusions under headings 9903.88.69 and 9903.88.70.
If you file a China-origin line under one of those headings today, the exclusion keeps the Section 301 list duty off that line. From November 10, unless USTR extends them, the list duty applies again, at the rate of the list the line is on.
Take 8479.90.95.91 from China, a line on the first Section 301 list at 25%. For entries through November 9, our API returns 9903.88.69 as an available_exemption on that line. For an as_of of November 10 or later, it no longer does. Whether a shipment qualifies depends on the exclusion’s product description, not on the code alone.
What to check now: list every China-origin line where your broker claims 9903.88.69 or 9903.88.70, find the list duty each one would owe without the exclusion, and price shipments that will be entered after November 9 both ways. As of October 19, 2026 we have not found an extension notice in the Federal Register. USTR has extended this set before, and the same December 2025 notice moved the date from November 29, 2025.
USTR separately confirmed on October 7, 2026 that the 2018 China Section 301 actions continue and said it will publish a notice describing a further review (FR 2026-20510). That notice, when it comes, will carry its own comment dates.
November 10: the maritime Section 301 suspension ends
In 2025 USTR suspended the responsive actions in its Section 301 investigation of China’s maritime, logistics and shipbuilding sectors for a year, from November 10, 2025. The modification notice (FR 2025-19873) amended headings 9903.91.12 through 9903.91.16 by “deleting ‘November 9, 2025,’ and by inserting ‘November 10, 2026,’”. As printed today, those headings apply to entries on or after November 10, 2026 of intermodal chassis and their parts, and of ship-to-shore gantry cranes.
The same notice says USTR “will consider whether it is appropriate to continue the suspension period or whether further action is appropriate in advance of the November 10, 2026 suspension deadline.” So this is the date most likely to change. If you import chassis, chassis parts or port cranes, watch for a USTR notice before November 10.
December 4: polysilicon
Proclamation 11052 (FR 2026-16400, signed August 6, 2026) adjusts imports of polysilicon and its derivatives under Section 232. From 12:01 a.m. ET on December 4, 2026, products in its Annexes I and II are subject to a minimum import price program, and “imports of polysilicon ingots and polysilicon derivatives specified in Annexes I and II of this proclamation shall be subject to an additional 15 percent ad valorem rate of duty.”
Clause (10) lets the Secretary of Commerce change how the program and the duty apply to a trading partner with “a substantially equivalent minimum import price”. So the December 4 terms can still differ by origin.
Until then a temporary Commerce rule (FR 2026-19537) is meant to stop stockpiling. It is “effective September 22, 2026, through December 3, 2026.” It applies weekly caps to importers registered with CBP on or after August 6, 2026, and can bar importers bringing in “volumes substantially greater than their historic averages.” It sets no duty.
Before December 4, check whether your ten-digit codes are on Annex I or II, and whether anything you plan to enter before then fits inside the stockpiling rule’s caps.
January 12, 2027: USMCA comments
USTR is taking comments on the operation of USMCA until “January 12, 2027, at 11:59 p.m. EST” (FR 2026-20341). At the joint review on July 1, 2026, the United States did not agree to extend the agreement for a new 16-year term, so the parties now review it every year. The agreement ends on July 1, 2036 unless all three confirm they want to continue. The hearing date has not been set; USTR says it will publish it on its website.
No duty changes on January 12. It is the date by which importers who rely on USMCA preference can put their case on the record.
February 9, 2027: a 25% duty starts on drone components
Proclamation 11055 (FR 2026-16979) put a Section 232 duty on the unmanned aircraft systems and components in its Annexes I and II from September 3, 2026. The components in Annex III carry no duty under it yet. Their start date is already written: “on or after 12:01 a.m. eastern time on February 9, 2027, for the UAS components listed in Annex III to this proclamation, the applicable ad valorem duty rate imposed pursuant to section 232 shall be 25 percent, unless a lower duty rate applies pursuant to clause (4) or (6) of this proclamation.”
If you import drone components, check which of your lines are on Annex III, and whether clause (4) or (6) gives you a lower rate. Our Section 232 page covers the program.
What these dates mean for a duty calculation
Every one of these changes turns on the entry date, so a landed-cost quote for goods that will clear after the date has to be priced on the new rules. Ask for the duty on the date the goods will be entered, not on the day you ask. Our API takes as_of for this: send the expected entry date and you get the rules our data holds for that day. Not every change on this page is in our data yet, and a notice published after you ask can move a date, so check the changelog for each one you rely on.
Common questions
Are the China Section 301 exclusions being extended past November 9, 2026? As of October 19, 2026 we have found no extension notice in the Federal Register. USTR has extended this set before. Watch for a USTR notice, and price shipments entered after November 9 both with and without the exclusion.
When does the Section 232 polysilicon tariff start? 12:01 a.m. ET on December 4, 2026, under Proclamation 11052: a minimum import price program and an additional 15% duty on ingots and derivatives in Annexes I and II. A temporary anti-stockpiling rule runs until December 3.
What is the deadline for USMCA review comments? January 12, 2027, at 11:59 p.m. EST, under FR 2026-20341. The hearing date has not been set.
When do the drone component tariffs start? February 9, 2027, for the components on Annex III of Proclamation 11055: 25% unless a lower rate applies under clause (4) or (6). Components on Annexes I and II have carried a Section 232 duty since September 3, 2026.
