Section 232 Inclusion Rebuttal — The Complete Guide

Executive summary

Section 232 of the Trade Expansion Act of 1962, codified at 19 U.S.C. § 1862, gives the President authority to adjust imports of any article the Secretary of Commerce finds threatens to impair national security. In practice this has meant tariffs and, less frequently, quotas. The steel and aluminum tariff regime established by Presidential Proclamations 9704 and 9705 in March 2018 has been amended repeatedly. The most consequential recent amendments came on February 10, 2025, when the President signed Proclamations 10895 and 10896, terminating the Bureau of Industry and Security product-specific exclusion program under 15 CFR § 705.5 and installing a rolling inclusion process in its place.

The inclusion mechanism runs in the opposite direction from the old exclusion channel. Under the terminated exclusion process, importers petitioned BIS to remove a specific product from the scope of the Section 232 tariff. Under the inclusion process, BIS periodically publishes Federal Register notices proposing to ADD derivative articles to Section 232 tariff coverage. Federal Register notice 2026-15961, published on August 6, 2026, proposed 14 additional derivative articles at a 25 percent rate; the public comment window on that notice closes at 11:59 PM Eastern Time on Wednesday Aug 27, 2026.

If a proposed inclusion covers an HTS heading you import, silence is expensive. A finalized inclusion means every entry under that heading carries the additional Section 232 duty from the effective date. Filing a rebuttal comment under 5 U.S.C. § 553(c) is the current administrative mechanism to argue the article should not be added. This guide walks the post-2025 framework, docket mechanics on regulations.gov docket BIS-2026-0331, the ten-section evidentiary framework that produces filings BIS can actually consider, the specific mistakes commenters have historically made, and the practical timeline from proposal to determination.

Section 1 — The February 10, 2025 process termination

Beginning in 2018, the Section 232 program on steel and aluminum ran a product-specific exclusion request channel administered by BIS under 15 CFR § 705.5 and the Section 232 Exclusions Portal at 232exclusions.commerce.gov. The channel let a US importer petition to have a specific 10-digit HTSUS classification exempted from the 25 percent steel or 10 percent aluminum tariff on grounds that the product was not produced in the United States in a sufficient and reasonably available quantity and quality. The Commerce Department received several hundred thousand requests over the life of the program. The processing backlog was substantial, adjudication was inconsistent across product categories, and objections from domestic producers frequently determined outcomes.

On February 10, 2025, the President signed Presidential Proclamation 10895 (steel) and Presidential Proclamation 10896 (aluminum), each of which terminated the product-specific exclusion process going forward. Existing granted exclusions remained valid until expiration under their original terms. New exclusion requests were no longer accepted. The BIS Exclusions Portal moved to read-only status. The reasons stated in the proclamations were administrative burden and inconsistency; the practical effect was to remove the individual waiver channel from the toolkit of every US importer touching steel or aluminum.

Together with terminating exclusions, the 2025 proclamations installed the inclusion mechanism as the ongoing lever the Section 232 program uses to adapt scope. Rather than adjudicating individual importer petitions, BIS periodically publishes proposed additions to the derivative-article annex and opens a public comment window on each proposal. The administrative-law framework governing that comment window is the notice-and-comment rulemaking procedure at 5 U.S.C. § 553, which is the same statutory basis that governs almost every substantive federal rule change outside the tax code. The general BIS regulatory structure sits at 15 CFR Part 705.

The overall Section 232 steel-and-aluminum program history since 2018 — Proclamation 9704 on steel, Proclamation 9705 on aluminum, Proclamation 10406 on the 2022 EU tariff-rate quota conversion, and the 2025 proclamations on exclusion termination — is the accumulated context every rebuttal is written against. BIS reads a new comment through the lens of that entire history, and a rebuttal that cites the wrong proclamation or the terminated exclusion framework signals a commenter who has not caught up with the current program.

Section 2 — Understanding the current inclusion process

The inclusion process runs through regulations.gov, the government-wide federal rulemaking portal operated jointly by the eRulemaking Program Management Office and the General Services Administration. Every Federal Register notice that proposes new Section 232 derivative-article inclusions carries a docket ID and a document ID. Federal Register notice 2026-15961 opened docket BIS-2026-0331, published Regulatory Identification Number 0694-XC166, and set a comment window running from August 4, 2026 through August 27, 2026.

Comment windows on inclusion notices historically run between 30 and 60 days. Every BIS-published notice states the exact deadline in its own preamble text. Comments filed after the deadline are docketed but do not enter the record BIS must respond to when writing the final rule — a distinction that matters, because the response record is what a court reviews if a final rule is challenged under 5 U.S.C. § 706. Filing on time is not a formality.

The evaluation criteria BIS applies to comments on a proposed inclusion track back to the Trade Expansion Act itself and the Commerce Department's original January 11, 2018 Section 232 steel report. The three principal criteria are national-security nexus (does the article support a national-security capability the domestic industrial base must retain), domestic capacity (does the United States produce this article at commercially meaningful volume today), and economic impact (what is the pass-through cost to US downstream buyers and consumers if the inclusion is granted).

The timeline from proposal to determination on a Section 232 inclusion notice is not fixed by statute. Historical practice has run 60 to 120 days from the close of the comment window to the final rule's Federal Register publication. On FR 2026-15961, the anticipated final rule window sits in November 2026 based on BIS's working cadence — verify the exact posture against the regulatory calendar as the date approaches. If your HTS code is included in the final rule, the additional Section 232 duty applies on entries with an effective date on or after the date stated in the final proclamation, and the additional cost basis flows through your entire supply chain from that day forward.

Section 3 — When to submit a rebuttal

Not every importer needs to file. The rebuttal is a real cost — drafting takes real time, and a poorly constructed one damages credibility. Four fact patterns produce a rebuttal that is worth writing.

First, your HTS heading is listed in a proposed inclusion. The 14 articles proposed in FR 2026-15961 map to specific HTSUS four-digit headings, from 7310 and 7311 for filled steel containers through 8544 for insulated electric conductor cables. If any of your entries in the last 12 months carry a heading on the proposed list, filing is worth considering. Run your codes through the TariffWatch exposure checker for a quick view; verify at the ten-digit level against the USITC Harmonized Tariff Schedule before drafting.

Second, you are directly exposed. Direct exposure includes importers of record, but it also includes US-based suppliers to importers and US-based customers that would absorb the passed-through duty. A US semiconductor manufacturer whose industrial-gas supply arrives in filled-container form under HTSUS 7310 has the same downstream economic stake in the FR 2026-15961 inclusion decision as the actual importer of record.

Third, you have documented economic impact. A rebuttal without numbers is a form letter. A rebuttal with a twelve-month CBP-entry record broken down by heading, a documented supplier list showing concentration, and a pass-through calculation that shows the downstream price effect on a specific downstream customer segment is substantively different. BIS adjudicators read filings with the assumption that documented cost impact reflects real business consequences and that undocumented hardship claims reflect none.

Fourth, you have a real national-security counter-argument or a real alternative-sourcing analysis. National-security counter-arguments are strongest when the article is a non-defense-critical input to a defense-critical downstream capability — a categorized Buy American Act finished item, an FDA-regulated hospital-supply product, an EPA-regulated municipal-water article. Alternative-sourcing analysis is strongest when the domestic supply base cannot substitute at the required volume and quality within a business-planning horizon, and the record shows exactly which domestic suppliers were contacted and what they said.

Section 4 — What a strong rebuttal looks like

The ten-section evidentiary structure the TariffWatch templates use maps directly to the criteria BIS lists in its inclusion notices. The ten sections are: (1) commenter identity and authorization, (2) product identification with HTSUS classification, (3) product-specific executive summary of the rebuttal position, (4) domestic-supply capacity analysis, (5) national-security nexus analysis, (6) documented domestic-supplier outreach record, (7) economic-hardship demonstration with entry data, (8) alternative-sourcing analysis, (9) precedent citations and rule interpretation, and (10) requested BIS action.

Primary-source evidence is the load-bearing element in sections 4 through 8. Domestic production and capacity data comes from US Census Bureau Economic Census and Annual Survey of Manufactures records under the appropriate NAICS heading, from the International Trade Administration's TradeStats Express and Otexa datasets, and from the Bureau of Labor Statistics employment records at the same NAICS level.

Import-value and volume data at the ten-digit HTSUS level comes from the USITC DataWeb system, which is the government-published version of the same trade data. The economic modeling that translates duty rate into pass-through price effect can rest on published US International Trade Commission investigations, which run price-elasticity and pass-through calculations on Section 232 and Section 301 tariffs periodically and publish the results.

National-security context is the section where commenters most frequently overreach. The Commerce Department's January 11, 2018 steel report set the baseline framing that Section 232 protects a domestic steel-and-aluminum industrial base BIS considers essential to defense-critical downstream capability. A rebuttal that argues the article at issue is a peripheral input to a defense capability — a strong Buy American Act argument, or an FDA-regulated medical article — can shift the balance. A rebuttal that argues Section 232 itself is illegitimate or that national security does not apply gains nothing.

Precedent citations matter because BIS reads the current comment against the record of past determinations. Every past exclusion grant on regulations.gov is discoverable through the docket search interface, and every prior inclusion notice with its final rule is available at the Bureau of Industry and Security Federal Register agency page. A rebuttal that cites two or three closely analogous prior determinations, notes the reasoning BIS applied, and maps the current facts to that reasoning reads as the work of a serious commenter and gets weighted accordingly.

Section 5 — Common mistakes

The first common mistake is the weak economic argument. A single sentence stating that the inclusion will hurt the commenter's business, without a documented pass-through calculation and without a specific downstream customer segment named, reads as boilerplate. BIS receives large numbers of such comments on every inclusion notice, and they do not affect the record. A four-line paragraph with a twelve-month entry value, an estimated pass-through rate to the downstream customer, and an aggregate cost estimate lands differently.

The second mistake is missing HTSUS specificity. A rebuttal that argues against inclusion at the four-digit heading level, when the rebuttal position depends on facts specific to a particular eight- or ten-digit subheading, invites BIS to grant the inclusion at the heading level and leave the subheading-specific facts unaddressed. Name the exact ten-digit HTSUS classification on every entry the rebuttal covers.

The third mistake is missing precedent. A rebuttal filed without citation to a single past exclusion determination or past inclusion final rule reads as though the commenter has not engaged with the framework BIS actually applies. Two or three well-chosen precedent citations, each briefly summarized, dramatically upgrade a filing.

The fourth mistake is late filing. A comment posted after the docket close is docketed but does not enter the response record. The August 27, 2026 deadline on FR 2026-15961 is a hard UTC deadline; the regulations.gov portal enforces it automatically.

The fifth mistake is citing the terminated exclusion framework. A rebuttal that argues the commenter's product should be excluded under 15 CFR § 705.5, or asks BIS to grant a product-specific waiver through the 232 Exclusions Portal, cites dead process. The correct framing is a rebuttal comment on a proposed rulemaking under 5 U.S.C. § 553(c). The request is that BIS not add the article to the derivative-article annex; it is not a request for a personal waiver.

Section 6 — DIY versus concierge service

The DIY path is real. The TariffWatch template library at /tariffwatch/inclusion-rebuttal publishes 14 free ready-to-file rebuttal templates, one for each proposed derivative article in FR 2026-15961. Each template ships the ten-section evidentiary structure, the article-specific narrative bank, and the primary-source citation list the rebuttal needs. Drafting time for an experienced importer working from a template runs 4 to 8 hours: assembling the twelve-month entry record from CBP data, running the pass-through calculation on the actual annual customs value, documenting the domestic-supplier outreach, and merging the placeholder fields into the template narrative.

Professional help falls into three tiers. A licensed trade attorney offers full-scope representation on the substantive filing and any follow-on adjudication. Rates run several hundred dollars per hour, and a straightforward rebuttal takes 6 to 12 attorney hours in most cases. A licensed customs broker under 19 CFR 111 offers technical HTSUS-classification verification and can prepare the entry-data section. Rates run lower, and turnaround is faster. Neither is a substitute for the other on a rebuttal that touches both economic and legal ground.

TariffWatch's file-for-me service is the third option. The service handles the ten-section drafting from your placeholder inputs, verifies HTSUS specificity at the eight-to-ten-digit level, documents the domestic-supplier check, and submits the completed rebuttal to regulations.gov docket BIS-2026-0331 under your name and organization authorization. Turnaround is 48 business hours from paid intake to submitted comment, and the service is available on each of the 14 article templates for $99. The service is not legal representation. A subsequent independent attorney review of the completed filing is available on request and priced separately.

Section 7 — What happens after you file

Filed comments are docketed within one business day and become part of the public record on regulations.gov. BIS reviews the docket after the comment window closes and prepares a final rule that responds to the record. Historical practice runs 60 to 120 days from docket close to final rule publication in the Federal Register. If BIS finalizes the inclusion, the final rule states the effective date and any transitional provisions; the additional Section 232 duty applies on entries as of the effective date. If BIS declines to finalize an article on the record, the article is omitted from the final rule and no additional duty applies to that heading under the current inclusion action. If BIS declines to finalize your specific rebuttal argument despite finalizing the inclusion, the options after the fact are the limited-appeal channels described in the FAQ below.

Section 8 — The August 27, 2026 window on FR 2026-15961

Federal Register notice 2026-15961, published on August 6, 2026, proposed to add 14 derivative articles to Section 232 tariff coverage at a 25 percent additional rate. The docket is BIS-2026-0331 on regulations.gov, and the public comment window closes at 11:59 PM Eastern Time on Wednesday Aug 27, 2026. The 14 articles span filled steel containers, brass-wind instrument parts, welding-machine parts, floor safes, insulated electric conductor cables, fire extinguishers, heat-exchange unit parts, hydraulic engine parts, mobile lifting frames, self-propelled cranes, tanker trailers, agricultural trailers, other trailers, and aluminum powder, mapping to HTSUS headings 7310, 7311, 7603, 8303, 8412, 8413, 8419, 8424, 8426, 8515, 8544, 8716, 9205 and 9209. Every article-specific TariffWatch template names the exact heading and rate at its top. Check your ten-digit code against hts.usitc.gov before drafting.
