Section 232 derivative products list

The Section 232 tariffs cover more than raw steel and aluminum. “Derivative” products are downstream articles made from covered metal — fasteners, structures, extrusions, and the auto-parts list — and they carry the same additional rate. The derivative lists have been expanded several times by proclamation and CBP CSMS message, so verify your exact HTS code with the lookup above.

Derivative coverage is defined code by code, not by product description — two similar articles can fall on opposite sides of the line. Confirm the current list against the BIS Section 232 portal and the latest CBP CSMS message for your HTS code before relying on it.

Frequently asked questions

Current Section 232 status, rates, effective dates, country scope, and how the programme stacks with other US tariffs.

What are Section 232 tariffs?+
Section 232 of the Trade Expansion Act of 1962 lets the US President impose tariffs or quotas on imports the Department of Commerce determines threaten national security. The current Section 232 tariffs apply to steel mill products (Chapter 72), steel derivatives (Chapter 73), aluminum and aluminum derivatives (Chapter 76 and listed downstream codes), passenger vehicles (8703), and a defined list of auto parts. The additional rate sits on top of the normal MFN duty.
What is the current Section 232 status in 2026?+
As of the most recent proclamations, Section 232 duties are 25% on steel and steel derivatives, 25% on aluminum and aluminum derivatives (raised from 10% in 2025), 25% on imported passenger vehicles, and 25% on covered auto parts. The 2025 expansion also removed most prior country exemptions and tariff-rate quotas. Because the programme is amended by proclamation rather than on a fixed schedule, check the effective rate for your specific HTS code with the lookup above and confirm against the latest CBP CSMS message.
What are the Section 232 effective dates?+
Steel and aluminum tariffs took effect in March 2018. Steel derivatives were added in January 2020 and aluminum derivatives in February 2020, with both lists expanded in 2025 when the aluminum rate rose to 25%. Section 232 tariffs on imported passenger vehicles took effect April 3, 2025, and on covered auto parts May 3, 2025.
What is on the Section 232 derivative products list?+
Derivative products are downstream articles made from covered metal that carry the same additional rate as the raw material. Steel derivatives sit largely in Chapter 73 — pipe and tube fittings, structures, tanks, wire products, and fasteners such as nails, screws, bolts and nuts. Aluminum derivatives cover extrusions, structures, stranded wire and cable, plus listed goods in other chapters. Autos are HTS 8703 and auto parts are a specified list within 8407–8716. Coverage is defined code by code, so verify your exact HTS number rather than reasoning from the product description.
Does Section 232 stack with Section 301 and MFN duty?+
Yes. Section 232 tariffs stack on top of the MFN duty rate, and on top of Section 301 China tariffs where both apply. A Chinese-origin steel product could face MFN duty plus Section 301 plus Section 232, with antidumping and countervailing duties on top of that. Check each programme separately and add the rates.
Which countries are exempt from Section 232 steel and aluminum tariffs?+
Following the 2025 expansion, prior country exemptions and tariff-rate quotas (Australia, EU, UK, Japan, Mexico, and the Canada melt-and-pour arrangement) were largely removed. Specific exemptions can change between proclamations and CBP CSMS messages — always verify current country scope against the BIS Section 232 portal and the most recent CSMS message for your HTS code before relying on an exemption.
Can I claim duty drawback on Section 232 duties?+
No. The Section 232 proclamations expressly bar drawback on the additional 232 duties. You can still claim drawback on the MFN duty paid on the same entry, and Section 301 duties are generally drawback-eligible — which often makes the 301 component the larger part of a claim.
How do I file a Section 232 product exclusion request?+
Product-specific exclusions are filed with the Bureau of Industry and Security (BIS) via the 232 Exclusions Portal. Importers can request an exclusion if the article is not produced in the United States in sufficient quantity or quality. Each exclusion is tied to a specific HTS code, importer, and supplier; granted exclusions are time-limited and must be renewed. The process is separate from Section 301 exclusions, which run through USTR.
