New Antidumping Duty and Countervailing Duty Petitions on Tin Mill Products from China, Taiwan, and Turkey

At a Glance

• United States Steel Corporation and the United Steelworkers Union filed antidumping duty petitions on tin mill products from China, Taiwan, and Turkey, and a countervailing duty petition on tin mill products from China.
• An investigation related to this petition could result in increased prices and/or decreased supply of tin mill products.
• The US Department of Commerce is expected to begin investigation on April 29, 2026.

On April 9, 2026, antidumping (AD) petitions were filed on tin mill products from China, Taiwan, and Turkey, and a countervailing duty petition was filed on tin mill products from China. The petitions were filed by United States Steel Corporation and the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union.

The US AD law imposes special tariffs to counteract imports that are sold in the United States at less than “normal value.” The US CVD law imposes special tariffs to counteract imports that are sold in the United States with the benefit of foreign government subsidies. For AD/CVD duties to be imposed, the US government must determine not only that dumping and/or subsidization is occurring, but also that there is “material injury” (or threat thereof) by reason of the dumped and/or subsidized imports. Importers are liable for any potential AD/CVD duties imposed. In addition, these investigations could impact purchasers by increasing prices and/or decreasing supply of tin mill products.

Scope

Please note that this section was not written by our authors but is taken verbatim from the petition.

The products within the scope of these investigations are tin mill flat-rolled products that are coated or plated with tin, chromium, or chromium oxides. Flat-rolled steel products coated with tin are known as tinplate. Flat-rolled steel products coated with chromium or chromium oxides are known as tin-free steel or electrolytic chromium-coated steel. The scope includes all the noted tin mill products regardless of thickness, width, form (in coils or cut sheets), coating type ( electrolytic or otherwise), edge (trimmed, untrimmed or further processed, such as scroll cut), coating thickness, surface finish, temper, coating metal (tin, chromium, chromium oxide), reduction (single- or double-reduced), and whether or not coated with a plastic material.

The merchandise subject to these investigations is currently classified in the Harmonized Tariff Schedule of the United States (HTSUS), under HTSUS subheadings 7210.11.0000, 7210.12.0000, 7210.50.0020, 7210.50.0090, 7212.10.0000, 7212.50.0000, if of non-alloy steel and under HTSUS subheadings 7225.99.0090, and 7226.99.0180 if of alloy steel. Although the subheadings are provided for convenience and customs purposes, the written description of the scope of the investigations is dispositive.

Estimated Dumping Margins

The petitioners allege dumping margins as follows:

• China: 202.02% to 1,077.08%
• Taiwan: 152.15% to 160.37%
• Turkey: 190.95% to 192.91%

The petitioners also allege subsidies with respect to subject imports from China, although the CVD petition does not quantify the alleged net subsidy margins.
