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 9705 and 9704 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 and installing a petition-based inclusion process in its place. Proclamation 11021 then terminated that inclusion process effective April 6, 2026; new derivative articles now come through Commerce and USTR notices on no fixed schedule.
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 per-article rates (mostly 25 percent); the public comment window on that notice closed at 11:59 PM Eastern Time on Thursday Aug 27, 2026, and the proposal is pending.
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 was the mechanism BIS offered to argue the article should not be added. FR 2026-15961 states the APA notice-and-comment requirements do not apply (military function, 5 U.S.C. 553(a)(1)); BIS nonetheless requested public comment. 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 through 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 (aluminum) and Presidential Proclamation 10896 (steel), 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 notice-and-comment rulemaking procedure at 5 U.S.C. § 553 does not govern it: FR 2026-15961 states the APA notice-and-comment requirements do not apply (military function, 5 U.S.C. 553(a)(1)); BIS nonetheless requested public comment. The general BIS regulatory structure sits at 15 CFR Part 705.
The overall Section 232 steel-and-aluminum program history since 2018 — Proclamation 9705 on steel, Proclamation 9704 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 6, 2026 through August 27, 2026.
Comment periods, when offered, vary by notice (BIS-14's ran Aug 6–27, 2026). 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 on-time comment record. Filing on time is not a formality.
FR 2026-15961 states: “The Department is particularly interested in comments and information on the following: (i) the aluminum, steel, and/or copper intensity of these products, (ii) whether imports of the products are of such volume as to undermine national security, (iii) the extent to which domestic production of the products can meet domestic demand, (iv) the effect on the economy, including domestic industry, if the products are included as derivative articles, and (v) any other relevant factors.” The national-security background is the Commerce Department's original January 11, 2018 Section 232 steel report.
The timeline from proposal to determination on a Section 232 inclusion notice is not fixed by statute or by Proclamation 11021, and we do not forecast a date for FR 2026-15961 — watch the docket and the Federal Register for the final notice. 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.

The Aug 27 window is one docket. New Section 232 derivative notices follow no fixed schedule under Proclamation 11021, and the next one may cover different HTSUS subheadings, with or without a comment window. The TariffWatch Watchlist is $29/mo (or $290/yr, two months free) for a weekly Monday digest of every BIS notice whose title matches your HTS codes.
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 codes, from 7603 for aluminum powder through 8544 for insulated electric conductor cables (filled steel containers are named by their contents codes, 2711.12, 2804.40 and 2901.22, with the duty on container value only). The comment window on that notice closed Aug 27, 2026. On a future notice whose window is still open, a code on the proposed list that matches your entries from the last 12 months is the signal to consider filing. 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 steel cylinders filled with oxygen or propene (contents HTSUS 2804.40.0000 or 2901.22.0000) 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 is organized around the five comment topics FR 2026-15961 lists. 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 argument, (6) documented domestic-supplier outreach record, (7) economic-hardship demonstration with entry data, (8) alternative-sourcing analysis, (9) supporting authority you locate and verify yourself, 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.
If you cite authority, locate and verify it yourself; TariffWatch does not research or supply precedent. Prior BIS Federal Register notices are available at the Bureau of Industry and Security Federal Register agency page. Cite only what you have read and can quote accurately.
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 citing authority you have not verified. If you cite a past BIS determination or Federal Register notice, locate and read it yourself; TariffWatch does not research or supply precedent, and a miscited determination costs credibility.
The fourth mistake is late filing. A comment posted after the docket close is docketed but does not enter the on-time comment 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 the terminated exclusion process, 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 the proposed notice. FR 2026-15961 states the APA notice-and-comment requirements do not apply (military function, 5 U.S.C. 553(a)(1)); BIS nonetheless requested public comment. 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. The templates stay up as DIY reference even though the paid filing SKU is closed.
Professional help falls into two live 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 $99 file-for-me / concierge service is closed and not for sale. The FR 2026-15961 comment window it filed into closed August 27, 2026, so we do not take payment for a filing we cannot submit on docket BIS-2026-0331. The 14 article templates stay free to read, copy, and file yourself. While the window was open the service handled ten-section drafting, HTSUS verification, and regulations.gov submission; that paid SKU is not for sale now. Start the Watchlist ($29/mo) to be emailed, in the Monday digest, when a new BIS notice's title matches your HTS codes. Neither the closed concierge SKU nor the free templates are legal representation.
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. No deadline is set for that decision, and we do not forecast one. 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 per-article rates that would replace, not stack on, any Section 232 rate in force: mostly 25 percent, agricultural trailers 15 percent all-in including MFN, and filled steel containers 50 percent on the container value only. The docket is BIS-2026-0331 on regulations.gov, and the public comment window closed at 11:59 PM Eastern Time on Thursday Aug 27, 2026; the proposal is pending. 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. The notice names specific HTS codes within headings 7603, 8303, 8412 (8412.90.9005 only), 8419, 8424, 8426, 8515, 8544, 8716, 9205 and 9209; the filled steel containers are named by their contents codes 2711.12.0020, 2804.40.0000 and 2901.22.0000. 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.
Section 9 — Frequently asked questions
Is a Section 232 inclusion rebuttal the same thing as an exclusion request?
No. The product-specific exclusion-request process operated through the BIS 232 Exclusions Portal was terminated by Presidential Proclamations 10895 (aluminum) and 10896 (steel) on February 10, 2025. A rebuttal is a public comment on a Federal Register notice that proposes to ADD a derivative article to Section 232 coverage. FR 2026-15961 states the APA notice-and-comment requirements do not apply (military function, 5 U.S.C. 553(a)(1)); BIS nonetheless requested public comment. The direction is opposite. An exclusion request asked BIS to remove your product from an existing tariff. A rebuttal asks BIS not to add your product in the first place.
How is a rebuttal different from a generic public comment letter?
A comment letter is any public input on a proposed rule and can be short, general, and non-technical. A rebuttal is a specific, targeted, HTSUS-precise submission that argues one or more of the 14 proposed derivative articles should not be added to Section 232 coverage. A well-constructed rebuttal follows a ten-section evidentiary framework and cites primary sources for every economic and national-security claim. Both are filed on the same regulations.gov docket, and both are part of the public record under the Administrative Procedure Act.
What happens if I miss the August 27, 2026 deadline?
The public comment window on Federal Register notice 2026-15961 closed at 11:59 PM Eastern Time on Thursday Aug 27, 2026, and the proposal is pending. Late-filed comments are not part of the on-time comment record. Proclamation 11021 lets Commerce and USTR add derivative articles by notice on no fixed schedule; they may seek comment on a future proposal, but are not required to. Set an alert on the regulatory calendar and be ready for the next notice.
Can I appeal a granted inclusion once it becomes final?
Appeal options are limited under the current framework. Judicial review of a Section 232 action is narrowly available under the Administrative Procedure Act at 5 U.S.C. § 706, but the Federal Circuit and Court of International Trade have historically deferred to the President on Section 232 determinations. The product-specific exclusion channel no longer exists. Practical options after finalization are duty-drawback where applicable, first-sale valuation, and country-of-origin restructuring — none of which are simple, and all of which require your customs broker and trade counsel.
How do I know if my HTS code is in the proposed inclusion?
Run your HTS list through the free TariffWatch exposure checker at /tariffwatch/checker. The checker matches your codes against the exact HTS codes Federal Register notice 2026-15961 names for its 14 proposed derivative articles; a shorter code that also covers codes the notice does not name gets a prompt to enter the full 10-digit code. For a manual check, look up your full 10-digit code at the USITC Harmonized Tariff Schedule and cross-reference it against the codes named in the Federal Register notice.
What if I am a small importer with modest volume?
Small-importer status is a legitimate rebuttal ground when the aggregate cost-impact argument is well documented. FR 2026-15961 lists five comment topics, including "the extent to which domestic production of the products can meet domestic demand" and "the effect on the economy, including domestic industry, if the products are included as derivative articles." A small importer that documents the pass-through cost onto US downstream customers, a narrow supplier base, and a plausible substitution-cost estimate produces a stronger comment than a passing reference to hardship. Aggregate the entire small-importer cohort where possible.
Can I file a rebuttal anonymously?
No. Comments filed on regulations.gov require a real name and an organization affiliation. The docket is public. Every comment, its submitter, and its supporting exhibits become part of the record and are visible to anyone who searches the docket. Confidential business information can be redacted from the public version and submitted separately under BIS confidential-treatment procedures — see the notice itself for the current instructions.
Do you offer attorney review of a rebuttal?
The template narratives and this guide are attorney-review-pending as of publication. A qualified US trade attorney or licensed customs broker should review any substantive filing before submission to the docket. TariffWatch is a data and workflow tool under 19 CFR 111, not a licensed customs broker and not a legal-advice service. The $99 concierge drafting service is closed and not for sale — the FR 2026-15961 window it filed into has closed, and we do not take payment for a filing we cannot submit. Templates stay free for DIY; the Watchlist ($29/mo) emails a Monday digest of new BIS notices whose titles match your codes. Neither the closed concierge SKU nor the free templates substitute for independent legal review of your specific facts.
