Section 232 Tariffs
Latest Update:
Section 232 was overhauled on April 6, 2026: duties now apply to the FULL customs value of covered products, not just the metal content. This is the single most important change for importers since the program expanded. Under the April 2, 2026 proclamation, the metal-content valuation method is gone; the duty now hits the entire entered value of covered steel, aluminum, and copper articles and their derivatives.
What Importers Need to Know Right Now:
- Full customs value, not metal content. For covered goods, the duty applies to the total entered value regardless of the percentage that is actually steel, aluminum, or copper.
- Current steel & aluminum rates: 50% on core metal articles (Annex I-A); 25% on listed derivatives (Annex I-B); a 15% transitional cap on certain industrial and electrical-grid equipment through 2027; UK 25% / 15% per trade arrangement; Russia 200%.
- Copper is now covered. Tariffs took effect August 1, 2025 — 50% on primary/most copper articles, 25% on certain derivatives — and folded into the full-value framework on April 6, 2026. Mandatory copper smelt-and-cast reporting in ACE began July 16, 2026.
- Autos & parts: 25% on covered passenger vehicles, light trucks, and parts, with a USMCA partial exclusion for U.S. content and a U.S.-assembly MSRP offset. Auto tariffs no longer stack with other tariffs.
- Medium & heavy-duty vehicles (MHDV) and buses: 25% on MHDVs and parts, 10% on buses, effective November 1, 2025.
- Wood products: 10% on softwood lumber, with higher rates on upholstered furniture and kitchen cabinets/vanities, effective October 14, 2025.

What Are Section 232 Tariffs?
Section 232 of the Trade Expansion Act of 1962 authorizes the President to impose tariffs (or other restrictions) on imports that the Commerce Department determines threaten U.S. national security. Unlike Section 301, which targets unfair trade practices, Section 232 rests on a national-security finding — historically focused on protecting domestic industries deemed essential to defense and critical infrastructure.
Section 232 first hit steel and aluminum in 2018 (25% and 10%, respectively). Beginning in 2025, the program expanded dramatically in both scope and rate.
What Section 232 Covers Today
- Steel — Chapter 72 and most of Chapter 73, plus listed derivatives.
- Aluminum — Chapter 76 and listed derivatives.
- Copper — added August 2025; primary articles and listed derivatives.
- Automobiles & auto parts — passenger vehicles, light trucks, and key parts (25%).
- Medium & heavy-duty vehicles, parts, and buses — added November 2025.
- Wood products — softwood lumber, upholstered furniture, and kitchen cabinets/vanities, added October 2025.
Additional Section 232 investigations (for example, into pharmaceuticals, semiconductors, and critical minerals) have been initiated and could expand the program further.
How Section 232 Differs From Other Tariff Tools
- vs. Section 301: Section 232 is national-security-based; Section 301 targets unfair trade practices. Section 232 goods are exempt from the 2026 Section 301 forced-labor duty.
- vs. Section 338 / IEEPA: Goods already subject to Section 232 duties are carved out of the 2026 Section 338 Canada tariffs, and Section 232 was unaffected by the Supreme Court's February 2026 IEEPA ruling.
Why the April 2026 Change Matters So Much
Before April 6, 2026, importers of many derivative products paid Section 232 duties only on the metal-content portion of the entered value — so a product that was 30% steel by value was dutied on that 30%. Now the duty applies to the full customs value of covered goods. For metal-containing finished products, that can multiply the duty owed several times over, making correct classification and metal-content analysis more financially consequential than ever.
The Section 232 Importer Guide: How to Check Your Exposure
Below is a condensed walkthrough for determining Section 232 exposure. For the full decision tree, including every annex, the 15% threshold test, and the U.S.-content and trading-partner rules, see the complete Section 232 Tariff Guide.
STEP 1 — Determine Your Product’s Annex
Everything flows from classification. Work through the annexes in order and follow the rules for the first one your product matches:
- Annex I-A — Core metal articles (steel, aluminum, copper made entirely or almost entirely of the metal, e.g., steel coils, aluminum sheet, copper rod): 50% on full customs value.
- Annex I-B — Derivative products (substantially made of the metal but not pure articles): 25% on full customs value.
- Annex II — Exempt products: out of scope entirely — no further analysis needed.
- Annex III — Industrial & electrical-grid equipment: reduced 15% transitional rate through 2027 (revocable; reverts to 25% on expiration or revocation).
STEP 2 — Apply the 15% Metal-Content Threshold (Annex IV)
For derivative products, run the two-part test:
1) Is it classified in HTS Chapter 72, 73, 74, or 76? If yes, Section 232 applies — return to your annex for the rate
2) If not, does it contain more than 15% steel, aluminum, or copper by weight? Above 15% → duty applies. 15% or less → no Section 232 duty.
STEP 3 — Check for Reduced Rates
- U.S.-origin metal content: derivatives made entirely with U.S.-melted-and-poured steel or U.S.-smelted-and-cast aluminum qualify for a 10% rate (U.S.-content threshold lowered to 85% in June 2026).
- UK: reduced rates (25% on Annex I-A, 15% on Annex I-B) per trade arrangement.
- Russia: 200% across the board — unchanged.
STEP 4 — Confirm the Cross-Cutting Rules
- No stacking across metals: a product is hit once even if it contains multiple covered metals.
- Drawback: significantly restricted; manufacturing drawback only, in narrow circumstances.
- FTZ: covered goods must be admitted under privileged foreign status.
- Smelt/cast documentation: country-of-melt-and-pour (steel/aluminum) and smelt-and-cast (copper, reporting live in ACE since July 2026) records remain critical.
For Autos, Wood, and MHDV
- Autos & parts: 25%; USMCA partial exclusion for U.S. content in vehicles; U.S.-assembly MSRP offset applies.
- MHDV & buses: 25% (MHDV/parts), 10% (buses); USMCA-compliant MHDV parts excluded pending a U.S.-value method.
- Wood: 10% softwood lumber; higher rates on furniture and cabinets/vanities.
Key Takeaways at a Glance
- Full customs value now governs — the metal-content method is gone (since April 6, 2026).
- 50% core metal articles / 25% derivatives / 15% certain industrial equipment through 2027.
- 10% for qualifying U.S.-metal-content derivatives; 200% Russia; reduced UK rates.
- Copper, autos, MHDV, buses, and wood are all now in scope alongside steel and aluminum.
- Drawback restricted; FTZ privileged foreign status required.
Previous Section 232 Updates
On Sept. 29, President Trump issued a proclamation under Section 232 imposing new tariffs on lumber, furniture, cabinets, and other wood products effective October 14, 2025, as outlined below:
– 10% global tariff on softwood lumber
– 25% global tariff on certain upholstered furniture, rising to 30% January 1, 2026
– 25% global tariff on kitchen cabinets/vanities, rising to 50% January 1, 2026
One important thing to note: All tariff provisions under Chapter 44 of the USHTS are being removed from Annex II of Executive Order 14257 for any shipments arriving to the U.S. on or after October 14th (there is no in-transit exclusion for this). This means any lumber products previously excluded from Annex II of Executive Order 14257 will be subject to reciprocal tariffs moving forward, if the product is not specifically identified in the Executive Order.
U.S. Trade “Partners” will receive more favorable treatment that reflects the terms of their trade deals, as defined below:
– UK is capped at 10%
– EU and Japan are capped at 15% combined MFN + 232 rate
– Other countries may face reciprocal tariffs if they are not under special treatment
The Commerce Department’s Section 232 report concluded that imports threaten U.S. national security by weakening domestic mill capacity, eroding competitiveness, and risking shortages for defense and critical infrastructure needs. Wood products are deemed essential for munitions, missile-defense systems, housing, transport, and the power grid.
The proclamation annex lists tariff subheadings covered. The administration also warned of potential additional tariffs to prevent circumvention and mentioned that countries negotiating with the U.S. may secure alternatives.
A new proclamation imposes a 25% tariff on specified automobiles and certain auto parts, in addition to existing duties. Here’s what you need to know:
– Scope and Timing: The tariffs apply to passenger vehicles (including sedans, SUVs, CUVs, minivans, cargo vans, and light trucks), as well as key automobile parts such as engines, transmissions, powertrains, and electrical components. Tariffs on automobiles take effect April 3 at 12:01 a.m. ET, while those on auto parts will begin no later than May 3, per an upcoming Federal Register notice. The full list of affected products will be defined in ANNEX I, which is pending release.
– USMCA-Originating Imports: Vehicles that qualify under the USMCA may be partially exempt, with the 25% tariff applying only to non-U.S. content, provided accurate documentation is submitted. If CBP determines that the declared non-U.S. content is overstated, the full value of the vehicle will be subject to the 25% tariff retroactively to April 3 for all entries of the same model by the same importer. For USMCA-eligible parts, tariffs will be delayed until Commerce establishes a process to apply duties specifically to non-U.S. content.
– Expansion Process for Additional Parts: By June 24, 2025, the Secretary of Commerce must establish a process for adding more parts to the Section 232 list upon request from domestic producers or industry groups. Requests must show that rising imports pose a national security risk. After submission, Commerce will consult with USITC and CBP, issue a determination within 60 days, and publish a Federal Register notice within 14 days. Newly added parts will face tariffs the day after publication.
– What’s Next: Expect additional Federal Register notices detailing affected products. President Trump also signaled possible future tariffs on lumber, pharmaceuticals, and computer chips during press remarks.
Effective August 18 at 12:01 a.m. ET, the department of Commerce has officially expanded the scope of Section 232 by adding new aluminum and steel derivative products to Annex I of the HTSUS. Importers should take immediate note of the following changes:
Aluminum Products (CSMS #65936615):
– Added under Proclamation 10895.
– New Products classified under subdivisions (j/k/r/s) of U.S. Note 19 are now subject to duties.
– Tariff rates range from 50% ad valorem (general) to 25% (UK-specific), with some exemptions at 0% for U.S.-processed products.
Steel Products (CSMS #65936570):
– Added under Proclamation 10896.
– New products classified under subdivisions (m/n/t/u) of U.S. Note 16 are now subject to duties.
– Tariff rates include 50% ad valorem (general) and 25% (UK-specific), with certain exemptions at 0% for U.S.-melted and poured products.
– Importers should consult the official Section 232 FAQs for critical details, including:
– Reporting country of melt and pour
– Steel/aluminum content valuation
– Reporting rules for goods subject to both steel and aluminum duties
Additional Notes:
– Russian aluminum duties remain at 200% (HTS 9903.85.67 / 9903.85.68).
– Reciprocal tariffs under EO 14257 apply to non-steel/aluminum content.
– No drawback is available for these duties.
– Foreign Trade Zone (FTZ) admissions remain restricted to “privileged foreign status.”
On Friday, February 14th, the official annex lists (containing all the specific HTS codes) were made available for steel and aluminum. The full list of codes can be found below in links to the official Federal Register Memos.
As a reminder, this renders all previous aluminum and steel agreements with trading partners invalid, effective March 12th. No exclusions or exemptions will be issued. However, if you have a current exclusion, it will be effective until the expiration date or until the volume has been exhausted.
– Aluminum Memo (Page 19 of Memo)
– Steel Memo (Page 24 of Memo)
Starting March 12, 2025, a 25% tariff will apply to all steel and aluminum imports, including specified derivative products. Additionally, an expanded list of derivative products will also be subject to tariffs. However, these tariffs will only take effect once the Secretary of Commerce confirms that an efficient system is in place to process and collect duties. As soon as the updated Annex listing the expanded derivative products is available we will share an update.
Key Details:
– Steel Tariffs: If a derivative steel product listed in the Annex is not classified under Chapter 73 of the HTSUS, the 25% tariff will apply only to the steel content of that product.
– Aluminum Tariffs: If a derivative aluminum product listed in the Annex is not classified under Chapter 76 of the HTSUS, the 25% tariff will apply only to the aluminum content of that product.
– Russian Aluminum: Any aluminum product or derivative made from primary aluminum of Russian origin will face a 200% tariff. (Primary aluminum refers to newly produced aluminum extracted from alumina via the Hall-Heroult process.)
– Exemptions for U.S. Steel & Aluminum: If a derivative steel product is made from steel melted and poured in the U.S., and certification is provided to CBP, it will not be subject to additional tariffs—regardless of where it was processed. The same applies to aluminum derivative products if CBP is given the necessary documentation. Guidance on required documentation will be published soon.
Trade Agreements & Exclusions:
– All previous trade agreements covering steel and aluminum imports with Argentina, Australia, Brazil, Canada, the EU, Japan, Mexico, South Korea, Ukraine, the UAE, and the UK will be terminated on March 12.
– Steel & Derivatives from Turkey: Imports will be subject to a 50% tariff.
– No More Exclusions: Effective February 11, 2025, no new exclusions or exemptions will be granted. Existing exclusions will remain valid only until their expiration date or until the approved volume is exhausted—whichever comes first.
Additional Changes:
– Adding More Products to the Tariff List: The Commerce Department has 90 days to establish a process for adding additional products to the Annex. U.S. steel and aluminum producers (or their industry associations) can petition to include more products, and Commerce will issue a decision within 60 days of a request.
– No Duty Drawback: These tariffs cannot be refunded through duty drawback claims.
– Strict Enforcement & Penalties:
– CBP will prioritize reviewing steel and aluminum classifications. If misclassification is found to avoid tariffs, penalties will be issued without mitigation.
– For aluminum misclassification, CBP will enforce maximum monetary penalties allowed by law.
– Foreign Trade Zones (FTZ): Any steel or aluminum product (or derivative) entering a foreign trade zone on or after 12:01 AM, March 12, 2025, must be admitted as “privileged foreign status” unless it qualifies for “domestic status”—meaning it will be subject to duties upon entry for consumption.
