Official article description
Articles of aluminum or of steel and derivative aluminum or steel articles the product of the United Kingdom, as provided for in subdivisions (c)(i)–(iv) 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)(i)–(iv) 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 + 25%”, Column 1 Special reads “The duty provided in the applicable subheading + 25%”, and Column 2 reads “No change”.
- Metals reached: Aluminum and steel articles and aluminum/steel derivatives.
- Origin condition: United Kingdom.
- Controlling note: U.S. note 16(c)(i)–(iv) and (d), in the legal notes to subchapter III of Chapter 99.
The UK rate is half the general rate, and the Column 2 entry is not generosity
Where a covered aluminum or steel article of most origins falls to 9903.82.02 at plus 50 percent, the United Kingdom line sits at plus 25 percent — the negotiated treatment recorded in subdivision (d) of U.S. note 16. Column 2 reads “No change” here, which is consistent rather than favourable: Column 2 applies only to products of the countries in general note 3(b), re-read in the Revision 15 General Notes on August 5, 2026 as Belarus, Cuba, North Korea and the Russian Federation. The United Kingdom is not among them, so the column can never be reached by a qualifying entry.
Origin, not shipment, decides it
The reduced rate is origin-conditional, so it turns on the country-of-origin determination for the article rather than on where it was shipped from. A UK-finished article made of non-UK metal is a substantive origin question, not a documentation formality, and getting it wrong moves the entry to 9903.82.02 and a 25-point rate increase. Derivative articles provided for in subdivisions (c)(vi)–(vii) go to 9903.82.05 at plus 15 percent instead, so the subdivision has to be settled too.
Frequently asked questions
What Section 232 rate applies to UK steel and aluminum?
Plus 25 percent on top of the applicable subheading duty for articles and derivatives provided for in subdivisions (c)(i)–(iv) and (d) of U.S. note 16, reported under 9903.82.04, as read from 2026 HTS Revision 15 on August 7, 2026. Certain derivative articles under (c)(vi)–(vii) instead go to 9903.82.05 at plus 15 percent. Both are lower than the plus 50 percent that 9903.82.02 applies to most other origins.
Why does 9903.82.04 show “No change” in Column 2?
Because Column 2 rates apply only to products of the countries listed in general note 3(b) — Belarus, Cuba, North Korea and the Russian Federation, re-read in the Revision 15 General Notes on August 5, 2026 — and the United Kingdom is not among them. The column is therefore unreachable for an entry that qualifies for this heading, and “No change” records that rather than granting relief.
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)(i)–(iv) 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.
