CBP发布钢、铝、铜232条款关税申报指引

The purpose of this message is to provide guidance on the implementation of the April 2, 2026, Proclamation, “Strengthening Actions Taken to Adjust Imports of Aluminum, Steel, and Copper into the United States.”

BACKGROUND In April 2, 2026, the President issued a Proclamation, “Strengthening Actions Taken to Adjust Imports of Aluminum, Steel, and Copper into the United States,” under Section 232 of the Trade Expansion Act of 1962, as amended (19 U.S.C. 1862). This proclamation imposes 10-50% additional duties on the full customs value of certain imports of steel, aluminum, copper articles (metal articles) and their derivatives from all countries, effective April 6, 2026.

Goods that are listed as articles or derivatives of more than one metal shall only be subject to one of the respective duty rates established by this Proclamation, even if the good contains aluminum and steel, aluminum and copper, steel and copper, or all three metals.

Goods specified in the annexes to the Proclamation that do not contain any aluminum, steel, or copper content shall not be subject to the duties imposed by the Proclamation.

In addition, goods specified in the annexes to the Proclamation, except those classifiable in Chapters 72, 73, 74, and 76 of the Harmonized Tariff Schedule of the United States (HTSUS), that contain less than 15 percent of the aggregate weight of the applicable metal(s) shall not be subject to the duties imposed by the Proclamation. The applicable metals, based on HTSUS classification, are identified in paragraphs (c)(i) through (x) of annex IV of the Proclamation. Do not include the weight of a metal in the 15 percent calculation where annex IV does not specify a metal for a specific HTSUS classification.

For example, since HTSUS is 8302.10.60 is identified in paragraphs (c)(vi) and (vii) of annex IV as both a derivative aluminum article and steel article in annex IV, the aggregate weight of both aluminum and steel (but not copper) should be included in the 15 percent calculation.
