Canada Steel and Aluminum Tariff Talks Lack a 25 Percent Entry Rule
Reports of a 25 percent U.S. tariff term for Canadian steel and aluminum do not identify which part of the existing Section 232 architecture would change. Importers should keep the current Chapter 99 and CBP instructions in force until an operative U.S. document identifies the covered products, calculation, effective date, and claim path.

No new 25 percent Section 232 entry rate is in force for Canadian steel or aluminum. The official record reviewed through 2.04 p.m. EDT on August 20 contains no final agreement, proclamation, HTS change, or CBP filing instruction that creates one.
The August 18 proclamation moves three separate Section 338 measures to August 22. It does not amend the metals regime.
Reporting that tariffs would fall from 50 percent to 25 percent is a negotiation term, not a filing rule. The implementing text must say whether 25 percent is a fixed Canada rate, a ceiling on combined duties, an in-quota rate, a product-path rate, or the rate otherwise in effect for the July 20 aluminum onshoring formula. Until then, keep the report in a negotiation field rather than the rate field of an entry model.
Why this is new
Section 338 and Section 232 remain separate. The August 22 Section 338 extension concerns listed Canadian alcohol, dairy, and motor vehicle products. Each of the three Section 338 proclamations excludes articles subject to duties under Section 232. A metals concession therefore requires its own operative Section 232 record.
The closer comparison is the July 20 Section 232 aluminum onshoring proclamation. It directs Commerce to establish a separate program for primary aluminum. If Commerce approves a company's plan, the proclamation directs the agency to allow an annual import quantity corresponding to the project's reasonably anticipated annual output at one-half of the Section 232 rate otherwise in effect. The public record reviewed here does not yet identify an approved plan, a Chapter 99 claim heading, or a CBP filing path for that program.
If a later Canada instrument makes 25 percent the otherwise applicable rate for a covered primary aluminum entry, and the July 20 formula is implemented without a different floor or priority rule, the arithmetic would produce 12.5 percent. Nothing in the current record makes 12.5 percent available. A later instrument could preserve the formula, set a minimum rate, treat the country term as an alternative benefit, limit it by quantity, or supersede the earlier rule. The implementing text must identify which treatment controls.
That choice can determine whether two importers of the same Canadian primary aluminum face the same rate, whether an approved project receives an additional benefit, and whether a broker can support the claim in ACE.
Current Section 232 rules already use 25 percent differently
Proclamation 11021, using product lists later modified by Proclamation 11032, assigns different functions to its annexes. Annex I-A generally carries a 50 percent additional duty on full customs value, subject to lower-rate clauses. Annex I-B generally carries 25 percent on full customs value, again subject to lower-rate clauses. Annex III temporarily brings the sum of the ordinary Column 1 rate and the Section 232 rate to 15 percent for products of normal-trade-relations countries, unless the product qualifies for the separate United States metal-content calculation or is subject to the higher non-NTR rule.
Proclamation 11032 added Annex I-C for a listed group of mobile industrial steel derivatives through December 31, 2027. For an Annex I-C product of Canada that qualifies for USMCA preference, the proclamation applies 25 percent to non-United States content and imposes a 15 percent minimum effective Section 232 duty on the imported product. CBP implements that floor by reporting non-United States content plus any United States content above 40 percent of entered value under heading 9903.82.20 at 25 percent. No more than 40 percent of United States content may be reported under heading 9903.82.21 without an additional Section 232 duty. If more than one clause 2 rate applies, the lowest applicable rate controls.
A 25 percent additional duty on full customs value is not the same filing rule as 25 percent on non-United States content or a 15 percent combined-duty total. The onshoring programs add company-specific formulas. A Canada instrument must identify which rule it changes.
Two half-rate programs do not share one floor
The United States already has two company programs that can touch Canadian aluminum, and their formulas are not the same. Proclamation 10984 created a program for certain Canadian and Mexican steel and aluminum producers that commit to new United States production capacity. Commerce may adjust the otherwise applicable rate by up to one-half, but not below 25 percent. Commerce's April procedures implement the approved treatment through headings 9903.82.18 and 9903.82.19 at 25 percent.
The July 20 primary aluminum directive is different. It tells Commerce to establish a program for approved onshoring plans and annual quantities tied to anticipated finished-project output. Its text sets the rate at half the Section 232 rate otherwise in effect and states no 25 percent floor. That silence does not create a 12.5 percent claim. A later Canada rule would have to say whether its rate enters that formula or displaces it.
Do not book 12.5 percent. It is only a possible result if a binding United States instrument makes 25 percent the rate otherwise in effect for the same Canadian primary aluminum entries covered by an approved, quantity-limited July 20 plan, preserves the half-rate formula, and adds no 25 percent floor or superseding rule.

A single negotiating number cannot support a blanket broker instruction. The implementing material must identify the annex, Chapter 99 heading, value base, approved quantity treatment, effective entry event, and rules for in-transit goods, warehouse withdrawals, and foreign-trade-zone merchandise.
What import teams should do
The primary file should be the SKU-level rate-transition matrix, not a general Canada deal memo. Each material line should preserve the ten-digit HTS classification, product annex, current Chapter 99 treatment, Canadian origin record, USMCA claim status, metal-content facts, current value basis, and current effective rate. Primary aluminum should carry separate fields for the applicable company program, approval status, authorized importer, approved quantity, remaining quantity, and operative Chapter 99 claim path.
Keep the reported term in a separate candidate column. Leave the proposed effective date, new legal authority, product scope, quota, floor, priority rule, refund treatment, HTS modification, and CBP message blank until a public record supplies them. A blank field is more accurate than a guessed 25 percent.
The broker instruction should remain tied to the current lane. A revised instruction needs the operative United States document, the exact entry trigger, the affected Chapter 99 provision, the rate or formula, and the evidence required for any content or quantity claim. A diplomatic announcement can trigger review. It cannot fill those fields.
What would change the calculus
A final political agreement would establish negotiating terms, but the rate file needs the United States instrument that gives those terms customs effect. The decisive record should identify the Section 232 authority, covered products, applicable countries, rate function, value basis, quantity limit if any, effective entry event, and relationship to earlier proclamations.
An HTS modification must connect the rule to the relevant headings and notes. Commerce documentation will matter if relief depends on an approved company, quantity, quota, or allocation. CBP guidance must explain the filing sequence, content data, quota claim, and ACE treatment. The rate file is ready only when those materials resolve the same transaction.
The half-rate issue needs an express answer. If the new instrument changes the rate otherwise in effect, importers need to know whether the July 20 formula follows that change. If the new instrument creates a floor or an alternative country benefit, they need the priority rule. Silence would leave a material claim question open even after the political bargain is announced.
Caveats
The source review closed at 2.04 p.m. EDT on August 20, 2026. Negotiations were active, so a later proclamation, agreement text, Federal Register notice, HTS release, Commerce action, or CBP message can supersede this assessment.
The 12.5 percent figure is a mathematical outcome under one hypothetical interaction. It is not a current rate, forecast, or claim instruction. The July 20 formula reaches only primary aluminum within an approved company's eligible quantity.
The matrix does not replace entry-specific decisions on classification, origin, USMCA eligibility, metal provenance, valuation, quota, foreign-trade-zone status, or unrelated duties. Until United States implementation identifies the covered lane and calculation, do not reprice a Canadian metals entry from the reported 25 percent term.
