Official article description
Derivative aluminum or steel articles the product of the United Kingdom, as provided for in subdivisions (c)(vi)–(vii) and (d) of U.S. note 16 to this subchapter
Transcribed verbatim from the live USITC export for 2026 HTS Revision 15 on Aug 7, 2026. The heading text points to U.S. note 16(c)(vi)–(vii) and (d); the enumerated scope lives in that note, not in the description above.
How this heading is treated
- Treatment: Additional duty on top of the ordinary subheading rate. Column 1 General reads “The duty provided in the applicable subheading + 15%”, Column 1 Special reads “The duty provided in the applicable subheading + 15%”, and Column 2 reads “No change”.
- Metals reached: Derivative aluminum and steel articles.
- Origin condition: United Kingdom.
- Controlling note: U.S. note 16(c)(vi)–(vii) and (d), in the legal notes to subchapter III of Chapter 99.
Derivative or article: the distinction sets the UK rate
The United Kingdom has two lines in this range and the split is not by product family but by where the goods sit in U.S. note 16(c). Articles of aluminum or steel and the derivatives listed in subdivisions (c)(i)–(iv) go to 9903.82.04 at plus 25 percent; the derivative articles listed in (c)(vi)–(vii) go here at plus 15 percent. Both are conditioned on subdivision (d), which is where the United Kingdom treatment itself is written. An entry team therefore cannot price a UK metal import from the origin alone — the subdivision decides a ten-point rate difference.
No copper limb, and no Column 2 exposure
The heading text covers derivative aluminum or steel articles only, so copper articles of UK origin are reached by 9903.82.06 at plus 10 percent or 9903.82.09 at plus 25 percent depending on the subdivision, with no United Kingdom-specific copper line in the 9903.82 range as read on August 7, 2026. Column 2 reads “No change” for the same structural reason as 9903.82.04: the United Kingdom is not a general note 3(b) country, so the column is unreachable.
Frequently asked questions
Which UK Section 232 heading applies to a derivative article?
It depends on the subdivision. Derivative aluminum or steel articles provided for in subdivisions (c)(vi)–(vii) of U.S. note 16 are reported under 9903.82.05 at plus 15 percent; those provided for in (c)(i)–(iv) fall to 9903.82.04 at plus 25 percent. Both require subdivision (d), the United Kingdom provision. Read the note against the article's classification rather than choosing by rate.
Does 9903.82.05 apply to UK copper?
No. The heading text covers derivative aluminum or steel articles only. Copper articles are reached by 9903.82.06 at plus 10 percent or 9903.82.09 at plus 25 percent depending on the note 16 subdivision, and there is no United Kingdom-specific copper line in the 9903.82 range as read from 2026 HTS Revision 15 on August 7, 2026.
How to use this page
A Chapter 99 heading is reported alongside an ordinary Chapter 1–97 classification, never instead of it, so this page is the second half of a two-part answer. Settle the ordinary classification and the country of origin first, then read U.S. note 16(c)(vi)–(vii) and (d) against the article, then select the heading. Where a rate threshold is involved, the test runs on the ad valorem equivalent for that entry, which makes it value-dependent rather than a fixed attribute of the part.
For the full 9903.82 map in one table, see Section 232 HTS Codes List & 9903.82 Duty Map, which lists every heading in the range with its treatment and cited subdivision. To be told when the range changes, see Section 232 steel and aluminum tariff alerts. For how a Chapter 99 overlay sits on top of the ordinary duty columns, see how U.S. import tariff layers fit together.
