Why the June 2026 CBP guidance matters for Section 232 monitoring
CBP CSMS 68855869 is the operational filing guidance for Proclamation 11032, the June 1, 2026 proclamation that further adjusted the Section 232 regimes for aluminum, steel, and copper. It confirms that the April 2026 framework applies 10-50% additional duties on the full customs value of covered metal articles and derivatives, then adds June 8, 2026 entry instructions for new and reduced 9903.82 headings. For a saved-code monitoring product, this is not a final rate for every code; it is a high-priority source trigger that tells import teams which Chapter 99 headings and annexes need review.
What stayed unresolved for a saved HTS code
The June guidance does not make every product with steel, aluminum, or copper automatically dutiable. Coverage still depends on whether the ordinary HTS code appears in the relevant annex or Chapter 99 note, whether the applicable metal content exceeds the de minimis threshold, whether U.S.-content or country-specific reduced treatment applies, and the entry date. None of Tariff Sentinel's current seed HTS records is a listed Section 232 metals line, so this change page remains a source-watch page rather than a calculator result.
Where to get the Section 232 HTS codes list and PDF
As verified August 4, 2026, the official Section 232 code-list trail has three parts: the live USITC 2026 HTS Revision 15 text for the controlling 9903.82.01–9903.82.26 headings, Proclamation 11032 and its annexes in the GovInfo Federal Register PDF, and CBP CSMS 68855869 with its downloadable Metals HTS List for operational filing mappings. The table on this page paraphrases every current 9903.82 heading, while the PDF and CBP attachment preserve the legal annex and filing snapshots. Reconcile all three to the HTS version and entry date that govern the shipment. Commerce's Section 232 inclusions docket is a separate watch surface because later decisions can expand derivative coverage.

Paraphrased from the live USITC 2026 HTS Revision 15 export, diffed row by row against Revision 14 on August 4, 2026 with no changes (Revision 13 was retrieved July 29). “No change” preserves the duty in the ordinary HTS subheading; a stated percentage can be an additional duty or a replacement Chapter 99 rate, as shown. Read the cited subdivision of U.S. note 16 before selecting a line.
This table maps Chapter 99 treatments, not ordinary product classifications. First confirm the Chapter 1–97 HTS code and the relevant subdivision of U.S. note 16; then check metal weight, origin, ordinary Column 1 rate, entry date, and the current CBP filing guidance. The CBP Metals HTS List is an operational cross-check, not a replacement for the live schedule.
26 9903.82 headings have their own page here, each carrying the verbatim article description, all three duty columns, and the cited U.S. note 16 subdivision — start from the Chapter 99 9903.82 heading index, or click a heading number wherever one appears as a row key to go straight to it.

Frequently asked questions
Did the June 2026 Section 232 guidance create an automatic duty for every steel, aluminum, or copper input?
No. It gives CBP entry instructions for listed metal articles and derivative articles under the 9903.82 headings. A shipment still needs a code-by-code review of the Chapter 99 note, the product's metal content, origin facts, and entry date before a Section 232 duty is assumed.
What changed from 95% to 85% in CSMS 68855869?
For specified headings, the threshold for a derivative article to qualify as made entirely from U.S. aluminum, steel, or copper moved from 95% to 85% by weight. The importer still has to support the applicable U.S. melted-and-poured, smelted-and-cast, or copper-content facts.
Why does Tariff Sentinel keep this as a source-watch notice?
The current catalog does not include a seed HTS code that is itself a listed Section 232 metals line. The value of the notice is monitoring: it tells an importer to check whether a saved product, component, or supplier-country scenario now intersects with the updated 9903.82 framework.
Where can I download the Section 232 HTS codes list PDF?
Use the GovInfo PDF for Proclamation 11032 and its legal annexes, then use the Metals HTS List attached to CBP CSMS 68855869 for the June 2026 filing mapping. For the current legal text, the live USITC 2026 HTS Revision 15 export lists all 26 headings from 9903.82.01 through 9903.82.26; the table above paraphrases that complete set. Neither download replaces an entry-specific review of the live heading, ordinary HTS classification, U.S. note 16 conditions, and entry date.

What to do with this notice
Compare the affected HTS list with your saved codes, then check whether the official text limits treatment by country, entry date, product description, importer action, or exclusion language. A notice can be important even when it does not immediately change the duty shown on a calculator.
Tariff Sentinel keeps the source URL, official PDF when available, and review status close to the affected-code list so teams can decide whether to update landed-cost assumptions, hold a purchase order, or send the source to a broker for a product-specific reading. Keep the reviewed source with the shipment file so later audits can show which notice informed the decision and when it was checked.
