New Section 232 Exclusion Code 9903.82.01: A Quiet Fix With Real Refund Potential for Importers
On April 27, the Department of Commerce published a Federal Register notice adding a new HTSUS subheading, 9903.82.01, that resolves a real gap in the April 2 Section 232 proclamation. The new code applies retroactively to April 6 and carries a 0% duty rate. For importers who have been paying Section 232 tariffs on products classified under HTSUS Chapters 72, 73, 74, and 76 that do not actually contain steel, aluminum, or copper, this is a refund opportunity. It also requires moving carefully, because the path to recovery runs through Post Summary Correction filings, and PSCs reopen entries for review.
This post explains what the new code does, why it exists, who qualifies, and how to claim refunds without inviting unnecessary scrutiny. The technical correction sits inside Docket No. 260424-0111. CBP also issued two technical corrections to Annex IV of Proclamation 11021 in the same notice and clarified the treatment of UK-origin steel produced from Netherlands-melted-and-poured material under HTS 9903.82.04 through January 1, 2028. The 9903.82.01 piece is what affects the broadest set of importers.
The gap that 9903.82.01 fills
To understand why the new code matters, it helps to look at how the April 2 proclamation was structured. Proclamation 11021 set up a five-tier rate structure for Section 232 metals tariffs: 50% on articles made entirely or almost entirely of steel, aluminum, or copper; 25% on derivative articles substantially made of those metals; 15% on metal-intensive industrial and electrical grid equipment through 2027; 10% on products made abroad with U.S.-origin metals; and 0% for articles where the metal content is 15% or less of the total weight.
The 0% tier was implemented through subheading 9903.82.03, which exempts goods where the aggregate weight of the applicable metal is less than 15%. But the language of 9903.82.03 expressly excluded goods classified in HTSUS Chapters 72, 73, 74, and 76. Those are the chapters that cover iron and steel (72), articles of iron and steel (73), copper and articles of copper (74), and aluminum and articles of aluminum (76). The logic was reasonable: if a product is classified under one of those chapters, the working assumption is that it contains the relevant metal.
That assumption does not always hold. Some products are classified under those chapters for tariff purposes but do not, in fact, contain the metal in question. That created a problem under Proclamation 11021. A product classified in Chapter 73 but containing no steel was subject to either the 25% or 50% rate, depending on its position in Annex I-A or Annex I-B, with no clear path to relief because the only existing 0% exemption excluded those chapters. 9903.82.01 closes that loop. It applies to articles falling under U.S. Note 16(c) that do not contain any aluminum, steel, or copper, regardless of their HTSUS chapter.
Who qualifies and what the conditions are
The most direct beneficiaries are importers whose products are classified in Chapters 72, 73, 74, or 76 but contain none of the three metals targeted by Section 232. The classification has to come from the standard tariff schedule rules, but the practical test for this exclusion is content. If the article contains no aluminum, no steel, and no copper, it is eligible regardless of how the chapter classification reads.
There is one important condition that comes with the exclusion. Importers using 9903.82.01 must apply the Global Tariff to the product. That is part of the trade-off. The article is not subject to Section 232 duty, but it is subject to whatever the underlying MFN or country-specific tariff rate is. For most products this is a meaningful net savings because Section 232 rates of 25% or 50% are well above standard MFN rates. But the calculation matters. Run the numbers before assuming the exclusion produces a refund.
The retroactive effective date of April 6 is the other significant feature. That is the same day the Section 232 changes from Proclamation 11021 took effect. Any qualifying entry filed since April 6 is eligible for the new code, which means importers who have been paying duty under the April 2 rate structure on products that do not contain the relevant metal can seek refunds for entries going back nearly four weeks at this point.
How to claim the refund: Post Summary Corrections
For unliquidated entries, the path is a Post Summary Correction. PSCs are the standard mechanism for amending entry summary data after the fact, and they can be used to apply the new exclusion code retroactively to entries filed since April 6. The PSC needs to claim 9903.82.01 on the entry summary line for the qualifying article, with the duty recalculated accordingly. The PSC can be filed up to 270 days from the date of entry, or up to 15 days before the scheduled liquidation date, whichever is earlier.
There is a real consideration to weigh before filing, though. CBP treats a PSC as the importer's assertion that the entry summary data is correct, and a PSC reopens the entry for review. C.H. Robinson noted in recent guidance that during a PSC review, CBP can examine bills of materials, production records, supply chain routing visibility, and documentation supporting tariff claims. The agency uses analytics, data-sharing, and whistleblower information to detect compliance risks, and even compliant importers can be flagged if their data resembles known risk patterns. None of this should deter a legitimate exclusion claim, but it does mean that filing a PSC without solid supporting documentation is a way to invite scrutiny that could go beyond the single entry.
The right preparation looks like this. Pull the bills of materials or technical specifications for the products you intend to claim under 9903.82.01. Confirm in writing that the articles contain none of the three metals. Tie the documentation to the entry numbers. Run the duty recalculation including the Global Tariff to confirm the math. Then file the PSC. If the documentation is in order, the PSC is a clean refund mechanism. If it is not, fix the documentation first.
For entries that have already liquidated within the past 180 days, the path is a protest under 19 U.S.C. 1514 rather than a PSC. The protest window is 180 days from the date of liquidation. For entries that liquidated more than 180 days ago, the recovery path is more limited and worth discussing with counsel.
The two technical corrections in the same notice
The April 27 notice also includes two technical corrections to Annex IV of Proclamation 11021. The first is the addition of 9903.82.01 itself, which is what we have been discussing. The second clarifies the treatment of UK-origin steel that is melted and poured in the Netherlands. Specifically, Tata Steel UK products that contain steel melted and poured in the Netherlands remain eligible for the lower UK-specific rate under HTS 9903.82.04 through January 1, 2028. After that date, those goods will fall under 9903.82.05, 9903.82.06, and 9903.82.09 at standard Annex I-B rates. CBP has indicated additional guidance will be issued before the transition date.
That clarification matters for any importer of UK-origin steel where the underlying material was processed in the Netherlands. The default assumption that UK origin equals UK rate is not necessarily accurate in those cases, and the January 1, 2028 transition is now on the calendar.
Country of origin reporting and other reminders
Two procedural notes that came out alongside the new exclusion. First, importers must continue to report countries of melt and pour for all subject steel and steel derivative products, and countries of smelt and cast for all subject aluminum and aluminum derivative products. The reporting requirements have not changed. Second, when claiming the 0% rate under 9903.82.03 (the low-content exemption that already exists), the aggregate weight of the applicable metal must be reported in kilograms as a second quantity on the entry summary line. CBP has not yet enabled copper smelt and cast country reporting in ACE but will issue a separate CSMS message when the functionality is ready.
