US Tariff Changes Calendar: What Changes, and When

A tariff rate is only right for a day. Importers order months ahead, so the rate that matters is the one in force when the goods are entered, not the one in force when the order was placed.

This calendar lists every dated US tariff change our engine holds, from the last 30 days to the next 12 months, with the total duty on example products before and after each date. Scheduled changes can be extended, changed or withdrawn before they start.

Rates worked out by the Zentria Flow engine on 13 Nov 2026 (tariff data version 2026.11.14). Estimate for planning, not a customs ruling.

Section 232 solar and polysilicon

A new Section 232 duty of 15% starts on solar modules, solar cells and silicon wafers and ingots, with a minimum import price on each and on polysilicon.

Products
Solar modules (8541.43), solar cells (8541.42), silicon wafers and ingots (3818.00, five statistical lines) and polysilicon (2804.61, minimum import price only). Minimum import prices: solar modules $0.38 per watt; solar cells $0.22 per watt; silicon wafers and ingots $100 per kg; polysilicon $21 per kg.
Origins
Every origin. UK goods pay 10%. For the EU, Japan, Korea, Switzerland, Liechtenstein and Taiwan the Section 232 duty is the amount that brings the normal MFN duty plus Section 232 to 15%. That 15% is not the total: for every origin the forced-labor Section 301 tariff is a separate duty, charged on top where the line is not exempt.

Example products: total US duty before → after

Engine notice: From 4 December 2026, solar modules pay an additional Section 232 duty of 15% (Proclamation 11052). The forced-labor Section 301 tariff is a separate duty and is charged on top of it where the line is not exempt: solar goods are not on that tariff's Section 232 exemption list (HTSUS ch. 99 U.S. note 52(f)). A minimum import price of $0.38 per watt starts the same day. Goods entered before that date are not affected.

Engine notice: From 4 December 2026, solar modules pay an additional Section 232 duty of 15% for goods of the EU, Japan, Korea, Switzerland, Liechtenstein and Taiwan (the amount that brings the normal MFN duty, 0% here, plus Section 232 to 15%: Proclamation 11052, clause 5(b)). That 15% covers the MFN duty and Section 232 only; it is not the total duty. The forced-labor Section 301 tariff is a separate duty and is charged on top of it where the line is not exempt: solar goods are not on that tariff's Section 232 exemption list (HTSUS ch. 99 U.S. note 52(f)).

Maritime Section 301 (cranes and chassis)

USTR's suspension of the additional 100% maritime Section 301 duty on ship-to-shore cranes and on Chinese intermodal chassis ends.

Products
Ship-to-shore gantry cranes in 8426.19.00 (heading 9903.91.14) and intermodal chassis, their subassemblies and parts in 8716.39.0090, 8716.90.30 and 8716.90.50 (heading 9903.91.12). Other goods in those codes pay nothing extra, so the engine reports the duty as a notice and never adds it to a total.
Origins
Products of China; also cranes from any origin with listed Chinese components or a Chinese-controlled maker.

USTR has suspended this action once and may suspend it again.

Example products

Engine notice: From 10 January 2027, unless USTR suspends it again, a ship-to-shore gantry crane (a high- or low-profile steel superstructure designed to unload intermodal containers from vessels, with spreaders or twist-locks) that is a product of China pays an additional 100% maritime Section 301 duty (heading 9903.91.14, HTSUS U.S. note 31(l)) on top of the 25% under heading 9903.92.10 (note 31(l)(i): the two stack), 125% in all on top of MFN. Cranes under a sales contract dated before 17 Apr 2025 and entered before 18 Apr 2027 are exempt (heading 9903.91.16); other cranes in 8426.19.00 are not affected. USTR has suspended it until 10 Jan 2027 (FR Doc. 2026-22867) and may suspend it again. Not included in this estimate: the HTS code alone can't tell.

Engine notice: From 10 January 2027, unless USTR suspends it again, intermodal chassis of China, their subassemblies and parts pay an additional 100% maritime Section 301 duty (heading 9903.91.12, HTSUS U.S. note 31(k)). Dry van, refrigerated van and flatbed trailers are outside the scope (USTR, 90 FR 48320), and other goods in this code pay nothing extra (heading 9903.91.13). Whether it adds to the 25% List 3 duty this code pays is not stated in the HTSUS (unverified). USTR has suspended it until 10 Jan 2027 (FR Doc. 2026-22867) and may suspend it again. Not included in this estimate: the HTS code alone can't tell.

Legal reference: Ship-to-shore cranes: HTSUS Rev. 23 heading 9903.92; Maritime Section 301: HTSUS Rev. 23 U.S. note 31(k)-(l), suspended to 10 Jan 2027 by FR Doc. 2026-22867

Section 232 unmanned aircraft

A Section 232 duty of 25% starts on parts and components for use in or with unmanned aircraft systems that do not already pay the 100% rate.

Products
Aircraft parts in 8807.10.00, 8807.20.00, 8807.30.00, 8807.90.90 when they are for use in or with an unmanned aircraft system (heading 9903.08.22). Parts for systems over 25 kg already pay 100%, and parts for other aircraft pay nothing extra, so the engine reports the duty as a notice and never adds it to a total.
Origins
Every origin. UK goods 10%, and goods of the EU, Japan, Korea, Switzerland, Liechtenstein and Taiwan 15% including MFN, when substantially all critical components come from the US or those partners.

The Secretary of Commerce may add components by notice, and the HTSUS does not print the new provision yet.

Example products

Engine notice: From 9 February 2027, parts and components for use in or with any other unmanned aircraft system pay an additional Section 232 duty of 25% (Proclamation 11055, clause 2 and Annex III; heading 9903.08.22, new U.S. note 43(c)(5)). Parts for systems over 25 kg already pay 100%. Parts not for use in an unmanned aircraft system pay nothing extra (heading 9903.08.20). Not included in this estimate: the HTS code alone can't tell.

Parts for systems over 25 kg already pay 100%. For goods of the EU, Japan, Korea, Switzerland, Liechtenstein and Taiwan, MFN and Section 232 together come to 15% when substantially all critical components and technology come from the US or its deal partners (heading 9903.08.24). Parts not for use in an unmanned aircraft system pay nothing extra (heading 9903.08.20). Not included in this estimate: the HTS code alone can't tell.

Source: Zentria Flow tariff engine, checked 13 Nov 2026. HTSUS 2026 Revision 23 (USITC, in force 10 Nov 2026, checked 10 Nov 2026): MFN rates, China Section 301 lists (chapter 99 U.S. notes 20 and 31) and forced-labor Section 301 exemptions (U.S. note 52). Dated rules as cited on each entry. Totals are the engine's full US duty rate for the HTS code and origin shown, in percent of the customs value, for goods that claim no trade-agreement preference. Estimate for planning, not a customs ruling. A rate is only right for a day: scheduled changes can be extended, changed or withdrawn before they start.

Watch a product and get an email when its cost changes

A calendar shows the changes already scheduled. The Watchlist covers the ones nobody has announced yet: a watched product is re-priced when its tariff changes, and you get an email with the old and the new cost. A free account watches 1 product; Growth watches every product you import.

Check a product, then watch it Plans and the Watchlist

How to read the calendar

The date is the US Eastern calendar day from which the new rule applies to goods entered for consumption. In force means the date has passed; Scheduled means the rule is published and has a start date ahead.

Before → after is the total US duty rate for one HTS code from one origin: MFN duty plus every additional tariff the engine applies (Section 301, the forced-labor Section 301 tariff, Section 232, Section 338). The engine is asked just before the date and on the date, so the difference is the change itself and nothing else.

A notice is a measure the engine reports but does not add to a total, because the HTS code cannot decide whether it applies. The example then shows the same total on both sides of the date, and the engine's own sentence says what to check.

Your product is probably not one of the examples. Use "Check your product on this date" and enter your own HTS code and origin: the checker prices any date from today to 12 months ahead and lists every dated change for that product.

What is not on the calendar

  • Measures that have been announced or proposed but are not yet in the engine with a start date.
  • Anti-dumping and countervailing rates for individual exporters, and administrative reviews of them.
  • Changes outside the United States. The calculator covers 70+ countries, but this calendar is US only.
  • Past schedules: the engine holds today's rates and the dated changes ahead, so the look-back is 30 days.

Tariff changes calendar: questions

Where do the dates on this calendar come from?

From the date rules inside the Zentria Flow tariff engine, the same engine that prices the tariff calculator. Each rule was entered from its legal source (a presidential proclamation, a Federal Register notice or the HTSUS itself) and is shown here with that reference. A date the engine does not hold is not listed.

How are the before and after rates worked out?

For each example product the engine is asked twice: just before the date and on the date. The two totals are the full US duty rate for that HTS code and origin (MFN duty plus every additional tariff that applies), in percent of the customs value. Nothing is typed in by hand.

Can a scheduled tariff change still be cancelled or moved?

Yes. Scheduled changes can be extended, changed or withdrawn before they start, sometimes days before. The China Section 301 product exclusions, for example, have been extended several times. Treat every future date here as the law as it stands on the day the page was checked.

Which date decides the rate my shipment pays?

In general the date the goods are entered for consumption in the United States (or withdrawn from a warehouse for consumption), not the date they were ordered or shipped. Goods on the water when a change starts usually pay the new rate. Ask your customs broker about your entry.

Is my product affected by one of these changes?

Open the checker from any example, replace the HTS code and origin with your own, and it shows the rate for that date and every dated change ahead for your product. A product no dated rule touches shows no scheduled change.

Why are anti-dumping duties and the maritime Section 301 duty shown without a change in the total?

Because the HTS code alone cannot decide them. Anti-dumping and countervailing cash deposits are set per exporter, and the maritime duty covers only some goods inside a tariff line. The engine reports them as a notice and never adds them to a total, and the calendar shows them the same way.
