Official article description
Except as provided for in headings 9903.82.15 and 9903.85.68, articles of copper and derivative aluminum and steel articles, as provided for in subdivisions (c)(ii), (iv), (vi)–(viii), (xi) and (e) 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)(ii), (iv), (vi)–(viii), (xi) and (e); 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 + 10%”, Column 1 Special reads “The duty provided in the applicable subheading + 10%”, and Column 2 reads “The duty provided in the applicable subheading + 10%”.
- Metals reached: Copper articles and aluminum/steel derivatives.
- Origin condition: Any origin except the Russian Federation, which is reached by 9903.82.15.
- Controlling note: U.S. note 16(c)(ii), (iv), (vi)–(viii), (xi) and (e), in the legal notes to subchapter III of Chapter 99.
Why the same product family appears at 10 and at 25 percent
The 9903.82 range routes articles of copper and derivative aluminum and steel articles to plus 10 percent here and to plus 25 percent under 9903.82.09, and the difference is not the product — it is which subdivisions of U.S. note 16 the article is provided for in. This heading draws on (c)(ii), (iv), (vi)–(viii), (xi) and (e); 9903.82.09 draws on (c)(vi)–(viii) and (xi) and steps aside for the rate-threshold headings 9903.82.20 through 9903.82.26. The subdivision citation, not the description, is the operative fact, and reading the two article descriptions side by side will not separate them.
The origin-specific equivalents
The Russian-origin counterpart of this line is 9903.82.15, at the same plus 10 percent, and this heading names it as an exclusion. Derivative aluminum containing Russian-smelted or Russian-cast primary aluminum goes to 9903.85.68 at plus 200 percent, also excluded here. Both exclusions have to be cleared before the plus 10 percent applies, and the second one sits outside the 9903.82 range where a heading-by-heading review of this subchapter will not find it.
Headings that displace this one
The article description opens with an “Except as provided for in headings” clause, so 2 headings take precedence over 9903.82.06. Rule them out before applying the treatment above.
9903.82.15— Russian copper and derivative steel — plus 10%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
9903.82.06 or 9903.82.09 — how do I tell which applies?
By the subdivision of U.S. note 16 the article is provided for in, not by the product description, because the two headings describe the same families. 9903.82.06 reaches subdivisions (c)(ii), (iv), (vi)–(viii), (xi) and (e) at plus 10 percent; 9903.82.09 reaches (c)(vi)–(viii) and (xi) at plus 25 percent and expressly steps aside for 9903.82.16 and 9903.82.20 through 9903.82.26. Read both notes against your classification and check the exclusion lists before choosing.
Does 9903.82.06 apply to Russian copper?
No. The heading excludes articles reported under 9903.82.15, the Russian Federation line for articles of copper and derivative steel provided for in subdivisions (c)(iv), (vii), (viii), (xi) and (e). 9903.82.15 carries the same plus 10 percent in Revision 15, but the correct heading still matters for the entry record and because the origin-specific rates have been adjusted separately from the general ones.
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)(ii), (iv), (vi)–(viii), (xi) and (e) 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.
