Section 232 now charges derivative metal goods on full customs value
Proclamation 11021 (2 April 2026, 91 FR 18201) moved steel, aluminium and copper articles and their derivatives onto full customs value, with 50%, 25% and 15% tiers. Proclamation 11032 (1 June 2026, 91 FR 34085) then changed the 15% tier and added more derivatives.

The four questions
Q1–Q4What happened
The April proclamation applies additional duties to the full customs value of covered metal articles and derivatives: 50% on articles made of the metals, 25% on derivatives predominantly made of them, and a temporary 15% on a subset of fixed industrial machinery and power equipment. CBP guidance assigns the covered lines to HTSUS headings 9903.82.01 to 9903.82.26. The June proclamation widened the 15% category to agricultural equipment and some residential HVAC components, and added products such as aluminium lithographic plates and steel racks.
When it takes effect
The April proclamation took effect on 6 April 2026. The June changes were published in the Federal Register on 4 June 2026. BIS opened a further inclusions process in August 2026, so the derivative list is not a fixed document. Check the issue in force on the entry date.
Who it touches
Any buyer importing a part that contains steel, aluminium or copper. Whether a bolt, a hand tool or a bracket is a covered derivative depends on its HTSUS classification and on the annexes in force, not on the product name.
What to do
Have your broker check the current inclusions list against the HTSUS code before the PO is issued. Ask us for the metal content and the declared customs value breakdown on the quotation, since a duty charged on full value is not the same number as one charged on the metal content. Where a part is borderline, we would rather send the classification question early than argue about it at the port.
Rules change. Check the source notices linked above for anything issued after the publication date.
