Proclamations 11061, 11062 and 11063, signed 8 September 2026, move the listed products from the 50 percent Section 338 duties to an exclusion from importation, effective for goods imported on or after 12:01 a.m. on 29 September 2026. Listed goods imported before that date but not yet entered remain subject to the 50 percent duty. The proclamations state that Canada did not remove the measures at issue after the August suspension, and cite Section 338's authority to exclude a country's goods where it maintains or increases the discrimination. No later Federal Register document changing the ban appears as of 8 October 2026.

Proclamation 11055, signed 13 August 2026. For companies on the Defense Department's Blue UAS Cleared List or Framework, or the FCC's Conditional Approval List, on 2 September 2026, the first-stage effective date for their listed products and components is 180 days after the proclamation's date. Companies with approved plans to build US production may import covered products and production equipment, in volumes tied to the planned facility's output, free of these duties while the facility is under construction. Commerce may add further components to the tariff.

Proclamation 11052, signed 6 August 2026. Its duties apply to goods entered on or after 12:01 a.m. on 4 December 2026, so none were being collected as of this date. Commerce may adjust the minimum prices. An importer found to have filed materially inaccurate documentation, along with its affiliates, is permanently barred from importing these products. Companies with approved plans to build US production may import production equipment and covered products, in volumes Commerce sets, free of these duties while their facility is under construction. A Commerce temporary rule, effective 22 September through 3 December 2026, lets Commerce bar further imports before 4 December by a company it finds stockpiling these products, and limits imports by importers that registered on or after 6 August 2026.

Proclamation 11051, signed 31 July 2026, a four-year safeguard. The rates and quota quantities are in the Annex, which the Federal Register prints as images rather than text: an annual in-quota quantity of 13,006,426 square meters in the first year, rising to 15,700,614 in the fourth, allocated by quarter. Imports from the excluded countries do not count toward the quota. The proclamation authorises USTR to negotiate agreements limiting exports of these products to the United States and, with the President's approval, to revise the measure for a partner with which it concludes one.

Applies to goods entered on or after 12:01 a.m. on 24 July 2026, the minute the Section 122 surcharge expired. The notice implements a presidential memorandum of 23 July 2026. The memorandum also directs USTR, once it finds it feasible, to set tariff-rate quotas letting a volume of specific textiles and apparel from Bangladesh, Cambodia, Indonesia and Malaysia enter free of these tariffs, sized to each economy's imports of US textile inputs and cotton.

Proclamations 11046, 11047 and 11048, signed 20 July 2026 under Section 338 of the Tariff Act of 1930, which the later proclamations state caps such duties at 50 percent ad valorem. Each states a finding that Canada discriminates against US commerce: provincial and territorial bans on buying or selling US alcoholic beverages (11046), eligibility rules for the USMCA cheese tariff-rate quota that differ from those for the EU under CETA (11047), and Canada's tariffs on US motor vehicles (11048). The duties were first set for 19 August 2026; Proclamation 11056 suspended them for 3 days, to 22 August, citing negotiations. As first issued they did not apply to goods subject to Section 232 duties; Proclamations 11064 (alcohol list) and 11065 (motor-vehicle list) added and removed products from 15 September 2026 and made the duty apply in addition to Section 232 duties. From 29 September 2026 some listed products were moved to an import ban, recorded separately. No later Federal Register document changing these duties appears as of 8 October 2026.

The investigation, opened in July 2025, covered digital trade and electronic payment services, preferential tariffs, anti-corruption enforcement, intellectual property, ethanol market access and illegal deforestation. USTR states it acted at the specific direction of a presidential memorandum of 15 July 2026. Brazil is also one of the 60 economies in the separate forced-labour action, at 12.5 percent, which applies from 24 July 2026.

The highest headline rate of any action in this dataset, and the only one with a scheduled increase four years out written into the proclamation itself.

Proclamation 11021, effective 6 April 2026. The duty now applies to the full customs value of the product, regardless of metal content, rather than to the metal content alone. Proclamation 11032 (signed 1 June 2026, effective 8 June) set a 25 percent rate through 2027 on articles in a new Annex I-C, with a combined MFN-plus-Section-232 rate of 15 percent for products of named trading partners and duty on non-US content only for USMCA-qualifying goods of Canada and Mexico. Proclamation 11045 (20 July 2026) directs Commerce to set up a program under which a company with an approved plan to build, refurbish or expand US primary-aluminum capacity may import primary aluminum, up to the plant's anticipated annual output, at half the Section 232 rate.

Proclamation 11012, signed 20 February 2026, the day the Supreme Court held IEEPA does not authorise tariffs. Section 122 permits a surcharge of up to 15 percent for no more than 150 days unless Congress extends it; the proclamation set 10 percent and ran it to the statutory limit. On 7 May 2026 the Court of International Trade, 2-1, declared the proclamation contrary to law (Oregon v. United States, Slip Op. 26-47) but enjoined collection only from the three importer plaintiffs it found had standing, dismissing the other states. The government appealed on 8 May; the Federal Circuit issued a temporary administrative stay on 12 May and, according to law-firm analyses of the order, granted a stay pending appeal on 11 June, so collection continued until the surcharge expired. See the linked entry for the litigation.

Ended by: Expired on its own terms at 12:01 a.m. on 24 July 2026, the end of the 150-day period Section 122 allows; Section 301 tariffs on 60 economies took effect the same minute

Proclamation 11002, signed 14 January 2026, effective for goods entered on or after 15 January 2026. The 25 percent applies to certain advanced computing chips and derivative products listed in the Annex, and not to imports for use in US data centers, US repairs or replacements, US research and development, startups, US non-data-center consumer or civil industrial applications, US public-sector applications, or other uses Commerce determines strengthen the US technology supply chain. The proclamation directs Commerce and USTR to pursue negotiations and states that, depending on their outcome, the President may consider broader tariffs on semiconductors and manufacturing equipment. A proclamation on processed critical minerals (11001), signed the same day, imposed no duty: it directs Commerce and USTR to negotiate agreements and to consider price floors.

The investigation, opened on 23 December 2024, concerned China's acts, policies and practices related to targeting of the semiconductor industry for dominance. The notice states the new tariff is in addition to the existing 50 percent Section 301 tariff on Chinese semiconductors from the forced-technology-transfer investigation. No Federal Register notice announcing the June 2027 rate had been published as of 8 October 2026.

The investigation, opened on 10 December 2024, covered Nicaragua's acts, policies and practices related to labor rights, human rights and fundamental freedoms, and the rule of law. USTR announced its determination that they are actionable on 20 October 2025, announced this action on 10 December 2025, and implemented it in the tariff schedule by a notice of 29 December 2025. The rate in force on this date is zero; the first non-zero step is scheduled for 1 January 2027. Nicaragua is separately one of the 60 economies in the forced-labour action, at 12.5 percent, from 24 July 2026.

Proclamation 10984, signed 17 October 2025. For USMCA-qualifying trucks other than buses, the 25 percent can apply only to the value of non-US content once Commerce approves the importer's documentation; USMCA-qualifying parts are not subject to the duty until Commerce sets up a process for applying it to their non-US content and publishes it in the Federal Register. Vehicles made at least 25 years before entry are exempt. Truck makers assembling in the United States may claim an offset equal to 3.75 percent of the value of the trucks they assemble, from 1 November 2025 through 31 October 2030. The same proclamation rewrote the automobile-parts offset in the April 2025 autos action so it runs through 30 April 2030. Commerce notices published in February, May and July 2026 set out procedures for the USMCA content submissions and the offsets; no later proclamation changing these rates appears in the Federal Register as of 8 October 2026.

The proclamation caps the rate for imports from the European Union and Japan at 15 percent. Amended in January 2026.

The proclamation also records the Secretary's recommendation of a phased universal tariff on refined copper of 15 percent from 2027 and 30 percent from 2028 — a recommendation, not an imposition, and recorded here as such. From 6 April 2026, Proclamation 11021 applies the copper duty to full customs value: 50 percent on most copper articles and 25 percent on the copper articles listed in its Annex I-B.

Ended by: Proclamation 11021 of 2 April 2026, which moved the tariff to full customs value

The proclamation modifies the earlier rates “from 25 percent ad valorem to 50 percent ad valorem” for both metals. The 50 percent rate on steel and aluminum articles was carried into Proclamation 11021, effective 6 April 2026, which applies the duty to a product's full customs value and sets separate rates for derivatives. See the row for that proclamation.

Ended by: Proclamation 11021 of 2 April 2026, which moved the tariff to full customs value

Executive Order 14257, the broadest of the IEEPA actions. The Supreme Court held 6-3 on 20 February 2026 that IEEPA does not authorise tariffs. CBP stopped collecting the duties on goods entered on or after 24 February 2026, the day a narrower Section 122 surcharge took effect. See the linked entry for the ruling, the replacement and the refund proceedings.

Ended by: Held unlawful in Learning Resources, Inc. v. Trump, then ended by Executive Order 14389

The proclamation provides that an importer approved by the Secretary may apply the 25 percent rate to the non-US content of a vehicle only; where content is not substantiated, the rate applies to the full value.

The proclamation records that domestic primary aluminium production fell 30 percent between 2020 and 2024 and that smelter capacity utilisation was 52 percent in 2024. Superseded in June 2025.

The proclamation records that imports from Canada rose 18 percent after Canada was excluded from the original tariff, and that import share reached nearly 30 percent in 2024. Superseded four months later when the rate doubled.

Executive Order 14193. Ended along with the other IEEPA duties by Executive Order 14389, which directs agencies to terminate collection.

Ended by: Executive Order 14389 of 20 February 2026

Executive Order 14195. The November 2025 order reducing the rate back to 10 percent records that it followed commitments made by China; the archive states the sequence and attributes the reason to the order rather than asserting one.

Ended by: Executive Order 14389 of 20 February 2026

Executive Order 14194, issued the same day as the Canada and China orders.

Ended by: Executive Order 14389 of 20 February 2026

The notice sets the additional duty at 10 percent from 24 September 2018 and states it will increase to 25 percent on 1 January 2019. This is the list that took the action from tens of billions to hundreds.

Took effect 23 August 2018 on the same 25 percent ad valorem basis as the first list. In the second statutory four-year review, domestic industries requested continuation, so the action did not terminate on 23 August 2026 (USTR notice, 7 October 2026).

The first of four lists. Unlike the IEEPA tariffs, the Section 301 duties were not disturbed by the 2026 Supreme Court ruling and continue to be collected. In the second statutory four-year review, domestic industries requested continuation, so the action did not terminate on 6 July 2026, its eight-year anniversary; USTR's notice of 7 October 2026 says it will conduct a further review of the actions.

Issued the same day as the steel proclamation and on the same stated rationale of restoring domestic capacity utilisation to about 80 percent. Superseded by the February 2025 proclamation, which removed the exclusions and raised the rate to 25 percent.

The proclamation states the tariff was set at a level the Secretary assessed would let domestic producers run at about 80 percent of capacity. The country exclusions and quota arrangements added over the following two years were removed in February 2025, and the rate was raised in June 2025.

A four-year declining schedule, set out in Annex I to the proclamation rather than in its text. Cells not assembled into modules also carried a tariff-rate quota, whose in-quota quantity the proclamation says is unchanged across the four years. The measure was continued by a later proclamation before this schedule ran out, and modified again in 2024.

Ended by: Proclamation of 9 February 2022 continuing the safeguard measure

A tariff-rate quota rather than a flat duty: a lower rate inside an annual volume and a much higher one above it, both declining over three years. Washer parts carried their own quota, rising from 50,000 to 90,000 units. The schedule is in the Annex, not the proclamation text.

Ended by: Proclamation of 21 January 2021 continuing the safeguard measure
