BIS Section 232 inclusion is a rolling process under 15 CFR Part 705 -- new comment windows typically publish in the Federal Register once per quarter, each running 30-45 days. If your HTS codes were hit by the BIS-14, they're still exposed on whatever docket lands next. TariffWatch Watchlist alerts you 30 days before the next window opens on any HTS code you monitor, for $29/mo.
Between 2018 and 2026, the Bureau of Industry and Security published Section 232 inclusion-request comment notices in the Federal Register at roughly a quarterly cadence -- with individual notices typically covering 5-15 proposed HTS derivative articles per notice. The Aug 6, 2026 notice (FR 2026-15961, the "BIS-14") was the most recent in that series; the next is statistically likely to publish before end-of-Q4 2026.
The regulatory authority itself doesn't change: 15 CFR Part 705 gives BIS ongoing power to add derivative articles under Section 232, and the Apr 2, 2026 restructuring shifted the tariff basis to full customs value of the finished derivative product. Every new inclusion window uses the same statutory mechanism. Missing one window doesn't remove the exposure -- it just defers the fight to the next window.
Not just Section 232. The Watchlist $29/mo tier monitors all six of these lanes against your HTS codes -- see the full U.S. trade regulatory calendar for every deadline in the next 90+ days, with primary-source citations.
CBP publishes a Federal Register notice each quarter announcing the interest rate applicable to overpayments and underpayments of customs duties, taxes, and fees under 19 U.S.C. § 1505(d). The Q4 2026 notice is anticipated in mid-September, effective Oct 1.
Commerce publishes monthly Federal Register notices listing antidumping and countervailing-duty orders whose anniversary month falls in the current period, opening 30-day windows for interested parties to request administrative reviews. The September notice typically closes around month-end.
Under the current Section 232 framework (Proclamation 9705 as amended and 15 CFR Part 705), the Section 232 Steel and Aluminum Inclusions Process opens periodic windows for domestic producers to request that additional derivative articles be brought under the existing 232 tariffs. The mid-quarter window is typically open for 21 days.
Section 307(a)(4)(A)(i) of the Trade Act of 1974 (19 U.S.C. § 2417) requires USTR to review Section 301 actions on the four-year anniversary if a domestic representative petitions for continuation. The current review, which produced tariff modifications published in the Federal Register in May and September 2024, remains an active process — USTR continues to accept exclusion requests and modification comments on a rolling basis.

Following the Aug 27 close of the comment period on Federal Register notice 2026-15961, BIS is expected to publish a final rule adopting some or all of the 14 proposed derivative articles into Section 232 coverage. Prior 232 rulemakings have moved from comment close to final rule in the 60-to-120-day range. The exact final scope and rates may differ from the proposal.
