How the Section 232 inclusions process actually works

Federal Register 2025-15819 (adopted August 19 2025) codified the standing Section 232 inclusions process. Before that, changes to 232 scope came through ad-hoc Presidential proclamations with variable notice periods and no standing comment mechanism. Post-adoption, the process has two paths and two comment windows per year.

This is the evergreen explainer on the two petition paths, filing mechanics, decision criteria, first-year grant rate statistics, and how the current August 27 comment window on 14 additional derivative categories fits into the standing process.

The two paths

Path A: domestic industry petition to ADD. Filed by US producers of the covered metal (aluminum, steel, copper) or by US downstream producers of derivative articles who face import competition from foreign articles containing covered metal. The petitioner asks BIS to add one or more HTSUS classifications to Section 232 covered scope. If granted, the added classifications pay the 232 layer (50 percent general, 25 percent UK) on the metal content share via producer affidavit or on the full invoice under the default rule.

Path B: exclusion petition. Filed by US importers, US downstream users, or foreign producers seeking to have an HTSUS classification removed from Section 232 scope (or to receive an entity-specific exclusion for a particular product from a particular supplier). If granted, imports of the covered article by the exclusion holder do not pay the 232 layer for the duration of the exclusion (typically 12 months, renewable).

Both paths use the regulations.gov docket structure and file into the same standing BIS docket that tracks 232 scope determinations. Different form fields and evidentiary requirements apply.

Filing mechanics for Path A (inclusion)

The domestic industry petition requires seven items.

1. Petitioner identification. Legal entity name, US EIN, primary NAICS, production facility addresses, and standing under the process (US producer of covered metal or US downstream producer of derivative article).

2. HTSUS classifications proposed for inclusion. 8-digit or 10-digit HTSUS numbers with statistical breakout precision. BIS prefers 8-digit for scope determinations and 10-digit for narrow surgical inclusions.

3. National-security nexus evidence. Documentation showing the article at issue is critical to national security under 19 USC 1862. DoD end-use certifications, DPAS-rated program citations, or industry association white papers on strategic materiel status.

4. Domestic capacity data. US production capacity for the article, current capacity utilization rate, and projected capacity availability at the proposed inclusion rate. BIS wants to see that domestic industry can meet demand if imports are curbed.

5. Import competition data. Actual import volumes and prices from covered origins over the last 24 to 36 months, showing the pattern of import surge or price undercutting that motivates the petition.

6. Downstream impact analysis. Effect on US downstream users of adding the 232 layer. BIS wants petitioners to acknowledge downstream impact and argue that national-security benefits outweigh downstream costs.

7. Alternative measures considered. Petitioner should note whether antidumping (AD) or countervailing duty (CVD) petitions have been filed or considered as an alternative, and why 232 inclusion is the preferred remedy.

Filing mechanics for Path B (exclusion)

The exclusion petition requires six items.

1. Petitioner identification. Legal entity name, US EIN, primary NAICS, role (US importer, US downstream user, foreign producer with US representation), and standing (documented import history for entity-specific exclusion, or industry association standing for scope-wide exclusion).

2. Product identification. HTSUS 8-digit or 10-digit classification, product technical specification, end-use description, and volume/value baseline.

3. Lack-of-domestic-substitute evidence. Documentation showing no US or FTA-partner supplier can produce the article at required specification, timing, or price point. Includes RFQ history from US suppliers, technical qualification records, and supplier capacity data.

4. Downstream user hardship data. Employment, revenue, capital expenditure exposure at the petitioner's facility or the petitioner's customer base if 232 layer applies without exclusion. Working capital drag from cash deposit at higher rate.

5. National-security offset argument. Where the article is not defense-critical, argue that excluding it does not undermine the national-security objective. Where the article is defense-critical, argue that the exclusion is entity-specific and does not open the scope broadly.

6. Duration and scope of requested exclusion. Typical exclusion is 12 months entity-specific for a specific product from a specific supplier. Broader exclusions require higher evidentiary burden.

Decision criteria BIS applies

Five criteria across both paths, with weighting varying by path.

1. National-security nexus. For inclusion, does the article warrant 232 protection under 19 USC 1862 statutory basis. For exclusion, does removing the article materially undermine the national-security objective.

2. Domestic capacity. For inclusion, can US producers meet demand at the inclusion rate. For exclusion, does US supply exist that could substitute for the excluded import.

3. Downstream impact. Effect on US downstream user industries. High weight in both directions.

4. Substitution feasibility. Can US buyers pivot to domestic or FTA-partner articles at similar specification, timing, and price point.

5. Precedent and consistency. Does the determination align with prior 232 decisions on similar articles. BIS is sensitive to setting precedent that could unravel the broader 232 regime.

First-year grant rate statistics

Aug 19 2025 through Aug 19 2026 was the first full year of the standing process. BIS docket data (as of Aug 15 2026 pull) shows:

Exclusion petitions. Approximately 1,240 filed. Grants: 223 (18 percent grant rate). Denials: approximately 1,017 including withdrawals and pending. Grant clustering by category: specialty chemicals with no domestic producer (67 grants), medical device components with FDA-qualified sole-source suppliers (48 grants), aerospace-qualified alloys (34 grants), semiconductor equipment parts (28 grants), residual specialty categories (46 grants).

Inclusion petitions. Approximately 87 filed. Grants: 41 (47 percent grant rate). Denials: 46 including pending. The higher inclusion grant rate reflects the priority on 232 scope expansion during the period and the stronger evidentiary case that domestic industry typically brings on national-security nexus. Inclusion grants tracked the two batch expansions: the Aug 2025 batch (Fed Reg 2025-15819 adopted 407 HTSUS) and the Q1 2026 batch (roughly 60 additional HTSUS across derivative categories).

Grant rate context. The 18 percent exclusion grant rate is comparable to the 2018-2020 first Trump term 232 exclusion rate (roughly 22 percent). The 47 percent inclusion grant rate is higher than historical because the standing process concentrated inclusion filings by industry associations rather than individual firms, producing better-organized petitions with stronger data.

How the current Aug 27 window fits in

Federal Register 2026-15961 (published Aug 6 2026, comment close Aug 27) is the Q3 2026 window under the standing schedule. Proposal covers 14 additional derivative categories: aluminum powder, brass-wind musical instruments plus parts, welding parts, floor safes, electric conductor cables, fire extinguishers, heat exchange parts, hydraulic engine parts, self-propelled cranes and straddle carriers, tanker trailers, agricultural trailers, other trailers, filled steel containers, and residual welding parts.

These 14 categories were surfaced by BIS based on inclusion petitions filed since the Q1 2026 window closed and internal BIS scope review. Public comment on the 14 categories closes 11:59 PM ET Aug 27. After comment close:

• BIS staff review: 30 to 60 days.
• BIS determination memo to Secretary of Commerce: within 30 days of staff review completion.
• Secretary decision: within 30 days of memo receipt.
• Presidential proclamation if adopted: typically 30 to 60 days after Secretary decision.
• CBP CSMS with effective date and Chapter 99 heading assignments: 7 to 14 days after proclamation.

Realistic effective date window: mid-October to late-November 2026 for adopted categories.

Timing of the standing windows and next opportunities

Two windows per year on the standing schedule.

Q1 window. Typically opens late February to early March, closes late March. Comment period 30 days. Cycle wrap-up (staff review, determination, proclamation, CBP CSMS) by mid to late June.

Q3 window. Typically opens late August to early September, closes late September. Comment period 30 days. Cycle wrap-up by mid to late December.

Next windows on the calendar:

• Q1 2027 window: expected to open late February 2027, close late March 2027.
• Q3 2027 window: expected to open late August 2027, close late September 2027.

Petitioners can prepare between windows and file on day one when the window opens. BIS treats early-filed petitions with the same weight as late-filed petitions within the window.

Practical guidance for importers watching the process

Three things.

One. Subscribe to the BIS 232 docket alerts on regulations.gov. Filings and Federal Register notices post to the docket with 24 to 48 hour lag. Watching the docket gives 30 to 60 day forward visibility on scope changes before they hit CBP CSMS.

Two. For any HTSUS classification you import at meaningful volume that touches steel, aluminum, or copper content, maintain a standing exclusion petition draft. If your classification gets caught in an inclusion, you can file the exclusion within 30 days of the CBP CSMS effective date and start the review clock immediately. Waiting until liquidation to challenge via protest is 12 to 18 months slower.

Three. Coordinate with your industry association on the Q1 and Q3 comment windows. Industry associations file better-organized petitions with aggregated data that BIS takes seriously. Individual firm comments carry weight when they include real economic-impact data with attached invoices, but association filings drive the framing on national-security nexus and domestic capacity.

The Aug 27 comment window is the current live cycle. Filing takes 30 minutes to two hours per comment. The next window opens in late February 2027. The standing process is now the primary mechanism for 232 scope changes and importers who ignore it are ceding the shape of their duty stack to petitioners who show up.
