Every heading in the 9903.82.01–9903.82.26 range, as read from the live USITC export for 2026 HTS Revision 18 on 2026-09-05. Heading numbers link to the page for that heading, which carries the verbatim article description and the cited U.S. note 16 subdivision.
This index maps Chapter 99 treatments, not ordinary product classifications. Confirm the Chapter 1–97 HTS code and the relevant subdivision of U.S. note 16 first, then the conditions that heading sets — metal weight and origin for 9903.82, the enumerated 8-digit subheading and entry date for 9903.88 — along with the ordinary Column 1 rate.
Three things the 9903.82 range gets used for, and one it cannot settle
The 9903.82 headings answer three operational questions. Which line does a covered metal article report on — the residual plus-50-percent line at 9903.82.02, or one of the narrower origin, threshold, or carve-out lines that displace it? What does the line actually do to the duty: 5 of the 26 Section 232 headings replace the ordinary Column 1 rate with a flat Chapter 99 rate rather than adding to it, and two put the duty in the Special subcolumn where a Column 1 comparison cannot see it. And which subdivision of U.S. note 16 has to be read before the line can be claimed.
What the range cannot settle is the ordinary classification. A Chapter 99 heading is reported alongside a Chapter 1–97 code, so the base subheading, the metal content, the country of origin, the ordinary Column 1 rate, and the entry date all have to be resolved first. Several lines here also carry an “Except as provided for in headings” clause that reaches outside the 9903.82range entirely — 9903.85.67 and 9903.85.68, the Russian aluminum provisions at the applicable subheading’s duty plus 200 percent — so a review scoped to this subchapter alone can miss the most expensive outcome available.
Chapter 99 9903.88 Section 301 headings — 6 lines with their duty treatment
| Chapter 99 heading | What the line covers | Treatment | Scope set by |
|---|---|---|---|
| 9903.88.01 | China Section 301 List 1 — plus 25 percent | The duty provided in the applicable subheading plus 25% | U.S. note 20(a) and 20(b) |
| 9903.88.02 | China Section 301 List 2 — plus 25 percent | The duty provided in the applicable subheading + 25% | U.S. note 20(c) and 20(d) |
| 9903.88.03 | China Section 301 List 3 — plus 25 percent | The duty provided in the applicable subheading + 25% | U.S. note 20(e) and 20(f) |
| 9903.88.15 | China Section 301 List 4A — plus 7.5 percent | The duty provided in the applicable subheading + 7.5% | U.S. note 20(r) and 20(s) |
| 9903.88.69 | Live USTR exclusion — entries from June 15, 2024 through November 9, 2026 | No change (The duty provided in the applicable subheading) | U.S. note 20(vvv) |
| 9903.88.70 | Live List 2 exclusion — entries from January 1, 2024 through November 9, 2026 | No change (The duty provided in the applicable subheading) | U.S. note 20(www) |
The 6 of 66 headings in the 9903.88.01–9903.88.70 range that this site publishes a page for, as read from the live USITC export for 2026 HTS Revision 18 on 2026-09-05. Heading numbers link to the page for that heading, which carries the verbatim article description and the cited U.S. note 20 subdivision.
This index maps Chapter 99 treatments, not ordinary product classifications. Confirm the Chapter 1–97 HTS code and the relevant subdivision of U.S. note 20 first, then the conditions that heading sets — metal weight and origin for 9903.82, the enumerated 8-digit subheading and entry date for 9903.88 — along with the ordinary Column 1 rate.
How the 9903.88 range is scoped differently
The Section 232 range decides coverage by what the article is made of and how much of it. The Section 301 range decides coverage by which 8-digit subheading the product classifies in, and nothing else: a code is on List 3 because U.S. note 20(f) enumerates it, and on List 4A because U.S. note 20(s) does. That is why two goods in the same four-digit heading can be 17.5 points apart — bags in 4202.92.31 carry the 25 percent List 3 overlay at 9903.88.03 while footwear in 6404.20.40 carries the 7.5 percent List 4A overlay at 9903.88.15 — and why no amount of reasoning about the product answers the question. Only the note does.
The second structural difference is the exclusion mechanism. Each Section 301 rate heading opens with an “Except as provided in headings” clause naming between twelve and twenty headings that displace it, and almost all of them are spent: their windows closed between 2020 and June 2024. Two still reach entries made now, both through November 9, 2026. They are not interchangeable. 9903.88.69 is named in all four rate headings’ clauses; 9903.88.70 is named only in 9903.88.02, so a 9903.88.70 exclusion is a List 2 route out and cannot be reported against List 1, 3 or 4A.
Which coverage this index claims, and which it does not
The Section 232 range is published in full: an export request spanning 9903.82.01 to 9903.82.99 returned exactly 26 rows on Sep 5, 2026, ending at 9903.82.26, and all 26 have a page. The Section 301 range is not. The equivalent probe from 9903.88.01 to 9903.88.99 returned 66 rows on Sep 5, 2026, ending at 9903.88.70, and 6 of them have a page here — the four list rate headings and the two live exclusion headings. The remaining sixty are exclusion headings that have lapsed or that state no window in the heading text, so a page asserting their status would be asserting something the schedule does not say.
The third range on this site is covered in a different shape. Headings 9903.05.01–9903.06.21 — the 2026 sixty-economy country action under U.S. note 52 and the separate Brazil action under U.S. note 50 — run to 110 lines, of which 65 are one-per-economy rate lines and the rest are carve-outs that displace them. Nothing there is answerable one heading at a time: the question is which heading in the band reaches a given origin and product, which is a comparison. So that range gets one decision page rather than 110 definitions — which 9903.05.01–9903.06.21 heading applies to your origin.
Frequently asked questions
What is a Chapter 99 heading?
A Chapter 99 heading is a temporary provision reported alongside an ordinary Chapter 1–97 HTS classification, never instead of it. It carries the trade-remedy or program treatment — an additional duty, a replacement rate, or an explicit no-change carve-out — while the ordinary subheading still supplies the base rate, the units, and the classification itself. The 9903.82 range holds the Section 232 aluminum, steel, and copper provisions; the 9903.88 range holds the China Section 301 list and exclusion provisions.
How many Section 232 headings are in the 9903.82 range?
26, from 9903.82.01 through 9903.82.26, as read from the live USITC export on Sep 5, 2026. That is a measured count rather than an assumption: an export request spanning 9903.82.01 to 9903.82.99 returned exactly 26 rows, ending at 9903.82.26. USITC published four revisions in fourteen days during 2026, so re-run the export against the current release before treating the count as fixed.
Which Section 301 headings have their own page?
Six of the 66 headings the 9903.88 range returns: the four list rate headings — 9903.88.01 (List 1), 9903.88.02 (List 2), 9903.88.03 (List 3) and 9903.88.15 (List 4A) — plus the two exclusion headings that still reach current entries, 9903.88.69 and 9903.88.70. The rest of the range is exclusion headings whose windows have closed or that state no window in the heading text at all, so their status has to be read from the U.S. note 20 subdivision each references rather than from the schedule. All six were read from the live export for 2026 HTS Revision 18 on Sep 5, 2026.
Why do two Chapter 99 headings sometimes have the same article description?
Because the distinguishing conditions live in the U.S. note the heading points to, not in the heading text. 9903.82.20 and 9903.82.21 both read “Derivative steel articles as provided in subdivision (j) of U.S. note 16 to this subchapter” in the live export, yet one adds 25 percent and the other reads “No change”. 9903.82.15 and 9903.82.16 are a second identical-description pair, fifteen points apart. Any mapping built from descriptions alone will get one of each pair wrong.
Does a stated percentage in this range always mean an additional duty?
No, and the distinction changes the amount owed. A column reading “The duty provided in the applicable subheading + 25%” adds to the ordinary rate. A column reading simply “15%” replaces the ordinary Column 1 rate, which is how the Section 232 threshold pairs at 9903.82.07/.08, .10/.11, .23/.24 and .25/.26 implement a minimum effective rate rather than a surcharge. Every Section 301 rate heading in the 9903.88 range is the additional form. Read the column text, not the pattern.
Are all 9903 headings covered here?
No, and the two ranges above are covered in a different SHAPE from the third. Tariff Sentinel publishes a page per heading for the 26 Section 232 headings in 9903.82.01–9903.82.26 and for 6 of the Section 301 headings in 9903.88.01–9903.88.70, because each of those headings is its own question. The 110 country-action headings in 9903.05.01–9903.06.21 — the 2026 sixty-economy action and the separate Brazil action — are covered by a single range page instead, because the question searchers actually ask there is which heading in a band applies to their origin and product, which is a comparison rather than a definition. Ranges outside 9903.82, 9903.88 and 9903.05 appear in reference tables and change notices with their official sources and have no page here.
