Section 232 Exposure Checker

Preliminary, automated exposure estimate — not a compliance determination and not customs classification advice under 19 CFR 111. Full disclaimer below.

Enter up to 10 HTS codes and your estimated annual customs value for a preliminary Section 232 exposure estimate, including the 14 proposed BIS derivative articles.

The BIS-2026-0331 comment window closed Aug 27, 2026.

Keep watching the codes you just checked

The checker above is free and stays free, but it is one snapshot of today. The scheduled BIS inclusions windows ended when Proclamation 11021 terminated that process on April 6, 2026; new Section 232 derivative notices now come from Commerce and USTR on no fixed schedule. TariffWatch Watchlist is the paid product that re-checks your codes against newly published notices every week.

TariffWatch Watchlist — $29/mo or $290/yr

Annual is the same product on one invoice (2 months free).

Up to 20 HTSUS subheadings per subscription. That is the honest cap — there is no per-code overage on this SKU.
Monday BIS digest, 09:00 UTC — the last 7 days of BIS Federal Register notices whose titles match your codes, with comment deadlines flagged. That email is the weekly digest, not a same-day alert.
A silent-week confirmation when nothing hit, so you can tell “nothing happened” from “the monitor died.”
7-day reverse trial on checkout — cancel before day 8 and you should not be charged.

Start Watchlist — $29/mo →Or pay annually — $290/yr

Both links open the same checkout page at /tariffwatch/watchlist and preselect the billing interval; monthly is the default. You enter an email there before Stripe — nothing is charged from this page. $58 is the difference between the $290 annual invoice and twelve monthly payments of $29 ($348); it is invoice arithmetic, not duty saved. We do not promise a dollar amount of duty saved, and neither the checker nor the Watchlist is legal advice or customs classification advice under 19 CFR 111.
