Official article description
Except as provided for in headings 9903.82.12, 9903.82.17 and 9903.85.68, derivative aluminum and steel articles with an ad valorem (or ad valorem equivalent) rate of duty under column 1 equal to or greater than 15 percent, as provided for in subdivision (f) 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(f); the enumerated scope lives in that note, not in the description above.
How this heading is treated
- Treatment: No change to the ordinary subheading rate. Column 1 General reads “No change”, Column 1 Special reads “No change”, and Column 2 reads “No change”.
- Metals reached: Derivative aluminum and steel articles.
- Origin condition: Any origin except general note 3(b) countries and Russian-origin derivative steel.
- Controlling note: U.S. note 16(f), in the legal notes to subchapter III of Chapter 99.
Claiming this heading is claiming a number, and the number belongs on the entry
9903.82.11 does not say Section 232 leaves the article alone. It says the article is covered under subdivision (f) of U.S. note 16 and that its Column 1 rate already reaches 15 percent, so the flat 15 percent in 9903.82.10 would not raise it. The supporting figure is the ordinary rate for that specific entry, and where the ordinary subheading carries a specific or compound rate that figure is a conversion against entered value rather than a constant. Keep the conversion, not just the heading, in the entry file.
Three headings built around 15 percent, and only this one leaves the rate alone
The range holds three lines organised around 15 percent and they do different things. 9903.82.10 substitutes a flat 15 percent Column 1 rate for a lower one. 9903.82.22 also substitutes a flat 15 percent, but for derivative steel of eleven named origins under subdivision (c)(xi), on an origin test rather than a rate test. This heading alone leaves the ordinary rate untouched. Reading “15 percent” as one treatment across the three is the error the structure invites, so confirm which of them the note and the origin actually point to.
Headings that displace this one
The article description opens with an “Except as provided for in headings” clause, so 3 headings take precedence over 9903.82.11. Rule them out before applying the treatment above.
9903.82.12— General note 3(b) origins — plus 25%9903.82.17— Russian derivative steel — plus 25%9903.85.68— outside the 9903.82 range; read it in the official USITC lookup
Tariff Sentinel publishes a page per heading only for the 26 9903.82 headings read directly against 2026 HTS Revision 15. The heading 9903.85.68 above sits outside that range, so it is cited to the official lookup rather than summarised here.
Frequently asked questions
Is 9903.82.11 an exemption from the Section 232 derivative duties?
No. It is the outcome of the note 16(f) threshold test: the article is covered, and its ad valorem or ad valorem equivalent Column 1 rate is already 15 percent or more, so the flat 15 percent in 9903.82.10 would not raise it. All three columns read “No change” in 2026 HTS Revision 15, read August 7, 2026.
Is 9903.82.11 the same as 9903.82.24?
No. Both read “No change” in all three columns, but they sit in different pairs. 9903.82.11 reports a Column 1 rate of 15 percent or more under subdivision (f) and covers derivative aluminum and steel articles; 9903.82.24 reports 10 percent or more under subdivisions (e) and (k) and also reaches articles of copper. An article at 12 percent clears the 9903.82.24 test and fails this one, so the two are not interchangeable even though their rate columns read identically.
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(f) 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.
