The duty base changed on April 6 2026
Before April 6 2026, the cited Section 232 metal measures used metal content as the duty base for defined covered categories. On or after that date, the ordinary duty base is full customs value for covered entries, subject to the annex and lower-rate limits in Proclamation 11021. The cut is the entry date, measured against the effective moment of one minute after midnight eastern daylight time on April 6 2026. Entries in the earlier window carry a duty-base question that later entries do not carry in the same form.
How the content window formed
The content-base record came from separate instruments. set the aluminum derivative rule, limiting the additional duty to aluminum content for derivative aluminum articles outside Chapter 76. set the steel derivative rule, limiting the additional duty to steel content for derivative steel articles outside Chapter 73 as of March 12 2025. raised the general steel and aluminum rates to 50 percent as of June 4 2025 while preserving separate United Kingdom treatment, kept the content measure for Chapter 73 steel and Chapter 76 aluminum, and told CBP to issue content-declaration guidance. set the copper rule for listed semi-finished copper products and intensive copper derivative products, limiting the additional duty to copper content. Together those instruments put a content-based measure on the public record before April 6 2026.
Proclamation 11021 changed the base going forward. It was signed on April 2 2026, published at 91 FR 18201 on April 9 2026, and applied the additional duty to the full customs value of covered aluminum, steel, and copper articles entered or withdrawn for consumption on or after April 6 2026. The metal-content limit that governed the earlier window no longer sets the ordinary duty base for those entries.
Why earlier liquidations remain open
The two windows do not answer each other. Proclamation 11021 gives a clear forward rule, but its effective-date language does not decide how earlier entries should have been valued. Those entries were made while the public record described a content measure, so whether CBP could assess them on full customs value depends on the earlier instruments and the declarations importers filed under them.
That split produces different work by date. Entries on or after April 6 2026 sit under the full-customs-value base rule. Content no longer limits the ordinary duty base, but it can still matter for coverage thresholds and lower-rate categories. Entries before that date sit under a content measure, so a full-value assessment on them is a valuation dispute rather than a settled charge.
A pre-April 6 full-value liquidation is not merely a refund question. It is first a protestable liquidation decision with a statutory clock. The work sits in the entry file and the protest calendar.
Legal and procedural posture
How CBP liquidated a covered entry is a customs decision, and the statute routes it through protest. 19 U.S.C. 1514 makes decisions on appraised value, rate and amount of duties, and liquidation protestable within 180 days after liquidation or reliquidation. 19 U.S.C. 1515 allows accelerated disposition, and a protest is deemed denied on the thirtieth day if CBP does not act within 30 days after a certified or registered mail request is mailed. 28 U.S.C. 1581 gives the Court of International Trade jurisdiction over an action contesting a denied protest, and 28 U.S.C. 2636 sets a 180-day deadline to file that action after notice of denial or denial by operation of law.
The statutory theories work best kept narrow. 5 U.S.C. 553 requires notice of proposed rulemaking for rules outside the listed exceptions, including interpretative rules and policy statements, and 5 U.S.C. 706 lets a court set aside agency action that is arbitrary, contrary to law, beyond authority, or taken without required procedure. The APA question is narrow. It turns on whether an instruction operated as binding law at liquidation rather than as interpretive administration.
19 U.S.C. 1625 covers interpretive rulings, internal advice, and the process for changing a prior ruling or a treatment previously accorded to substantially identical transactions. It helps only if the entry file or a public ruling record shows a prior ruling or a prior treatment. 19 U.S.C. 1401a is the appraisement statute, and it should not carry the main argument unless the entry record shows a separate appraisement dispute. The stronger claim is that CBP used a duty base inconsistent with the governing proclamation text. 44 U.S.C. 3512 protects against penalties for an information collection that lacks a valid control number or notice, which is a reporting or penalty defense rather than a duty-base theory.
The court's posted 2026 slip-opinion page does not show a public slip opinion resolving this valuation issue. This analysis rests on the proclamation record and the statutes rather than on any docket.
Why this is new
This analysis does not turn on the validity of the Section 232 metal measures. For entries before April 6 2026, the question is which instrument set the duty base and whether the importer preserved the protest route to test it. That moves the dispute off the tariff and onto the entry file and the valuation record.
What importers should do
Importers should split entries by date. Entries on or after April 6 2026 sit under Proclamation 11021 and the full-customs-value base. Importers should pull every pre-April 6 entry liquidated under a covered aluminum, steel, or copper Section 232 provision, because the operative public record used content measures in Proclamation 10895, Proclamation 10896, Proclamation 10947, and Proclamation 10962.
For each of those entries, the file should show the liquidation date, the declared metal-content value, the method used to derive it, the supplier support, the broker reporting trail, and any CBP notice. It should show whether a Post Summary Correction was filed before liquidation and whether the protest preserves the valuation, rate, liquidation, and procedural objections under 19 U.S.C. 1514.
Calendar from the liquidation date. The protest window runs 180 days from liquidation or reliquidation under 19 U.S.C. 1514, and a denied-protest action runs 180 days from notice of denial or denial by operation of law under 28 U.S.C. 2636. For a faster court path, 19 U.S.C. 1515 gives a 30-day deemed-denial after a proper accelerated-disposition request.
What would change the calculus
A Court of International Trade decision on whether pre-April 6 metals entries could be assessed on full customs value would give the first public judicial marker for the closed window. New CBP guidance would matter if it addresses Annex I-B, Annex III, Annex IV, or the documentation needed to support content-based thresholds and lower-rate categories. A Federal Circuit ruling on how the protest route interacts with APA review would reset the map for importers with preserved pre-April 6 protests.
Caveats
This analysis rests on the public proclamation record and the protest and review statutes. It does not rely on any docket filing or reported litigation, and it does not confirm the existence, wording, or legal effect of any internal CBP instruction. The post-April 6 rule is full customs value for covered goods, but the annex structure still controls whether an article is covered and whether a no-content or insufficient-content limit applies.
