If you import aluminum powder classified under HTSUS heading 7603 and want to file a comment on the BIS-14 proposal at Federal Register notice 2026-15961, the TariffWatch template at /tariffwatch/comment-letter/aluminum-powder is a starting point sized for a real filing. This guide walks each section of the template, what the underlying regulation requires it to contain, the mistakes commenters most frequently make, and how the former file-for-me service handled them before the Aug 27 2026 window closed. Watchlist $29/mo emails a Monday digest of new BIS notices whose titles match your codes; templates stay free DIY.
Section 1: Executive summary
The template opens with a plain-language paragraph naming the article (aluminum powders of non-lamellar structure, HTSUS 7603.10.0000), the notice (Federal Register notice 2026-15961 on federalregister.gov), and the requested outcome. This section is your one-paragraph pitch. BIS reviewers read hundreds of comments per docket, and a comment that buries its ask three sections deep loses signal.
The notice does not mandate an executive summary. It says the Department is "particularly interested in comments and information on" five listed topics, ending with "(v) any other relevant factors", and a summary that names the topics you address on line one is the fastest way to signal you did.
Section 2: Article-specific impact
The template's second section walks concrete detail on your imports, HTSUS sub-headings, annual volume, supplier country, and downstream product qualification timelines. The reference to AS9100 aerospace certification and multi-year requalification cycles is specific because BIS scores comments on evidentiary weight, and volumetric claims without specifications do not score.
The most common commenter mistake here is HTSUS non-specificity. A comment that says "we import aluminum" without naming a 10-digit sub-heading is treated as an unfocused industry-position statement, not evidence about a specific article. The template's placeholder for {{HTS_CODES}} exists so that you populate real 10-digit sub-headings from your own commercial invoices. Reference for the classification structure is at the CBP rulings and classification resources on cbp.gov, the operational authority Customs uses for classification decisions.
Section 3: Alternative recommendation
The template gives three ranked asks (exclude the heading entirely, phase implementation over 18 months, or establish a product-specific exclusion process). This ranking matters. A comment that only says "please exclude us" without a fall-back position is easier to dismiss than one that gives BIS a concrete phased-implementation option to adopt.
The template's third ask is that BIS provide a product-specific exclusion in the final derivative-article rule itself. The former Section 232 product-exclusion process was terminated by Presidential Proclamations 10895 (aluminum) and 10896 (steel) on February 10, 2025, and the BIS exclusions portal is now read-only, so the template does not cite that process as authority.
Section 4: Supporting authority
The template closes with citations to Presidential Proclamation 9704 (2018, aluminum), the January 2018 Commerce aluminum report, Section 232 itself (19 U.S.C. § 1862), and Proclamation 11021 of April 2, 2026: FR 2026-15961 proposes the new derivative articles "pursuant to Proclamation 11021", with duties "imposed under Proclamations 11021 and 11032." It does not cite specific BIS exclusion determinations; add any you have located and verified yourself. A comment that cites the underlying legal framework signals to the reviewer that the commenter understands what BIS can and cannot do.
Common mistake: commenters treat this section as optional. It is not. A comment that cites no authority at all reads as advocacy rather than as evidence.
Common commenter mistakes summary
Three common failure modes: HTSUS non-specificity (already discussed), weak economic-impact framing (dollar figures without volume, or claims without contracts), and authority you have not verified. The template scaffolds the first two and leaves the third to you, and the placeholders ({{ANNUAL_VOLUME}}, {{US_EMPLOYEES}}, {{PROJECTED_COST_IMPACT}}) require your real numbers, not the illustrative examples the template ships with.
How the former file-for-me service handled this (closed)
The former $49 file-for-me service at /tariffwatch/comment-letter/file-for-me/aluminum-powder collected your placeholder values through a short form, then a licensed U.S. attorney reviewer merged them into the template, verified HTSUS specificity, tightened the economic-impact framing to match BIS's published scoring guidance, and filed the completed comment into the docket at regulations.gov before the Aug 27 2026 deadline. That window is closed; the service is not for sale. Watchlist $29/mo emails a Monday digest of new BIS notices whose titles match your codes; templates stay free DIY.
FAQ
Do I need a lawyer to file a BIS comment? No. The comment docket is open to anyone. That said, a comment that engages the five topics the notice lists is easier for BIS to use than one that does not.
Is aluminum powder really different from primary aluminum? For Section 232 purposes, yes. Primary aluminum is already covered by the original 2018 action. The Aug 6 2026 BIS-14 proposal (91 FR 50756) contemplated extending coverage to derivative articles like non-lamellar aluminum powder (7603.10.0000), which is why that comment window was separate from the 2018 action. It closed on Aug 27 2026 and is not open.
What if my Aug 27 filing is late? Late-filed comments are treated as post-docket-close submissions and are docketed for the record but not weighted in BIS's decision-making. The former file-for-me service closed after the Aug 27, 2026 window at 11:59 PM Eastern Time (03:59 UTC on Aug 28) and no longer takes commissions.
