TariffWatch maps your HTS codes against Section 232 derivative-article categories and estimates duty exposure. The 60-second free exposure check needs no account. Watchlist is $29/mo and emails a Monday 09:00 UTC digest of BIS Federal Register notices that touch your codes. Not a licensed customs broker under 19 CFR 111, not a filer of record, not legal advice. Built by Digital Empire Holdings LLC / EnforceIntel.
BIS keeps opening Section 232 derivative-article windows on a roughly 90-day cadence. The Aug 27 2026 window closed; the next one will not wait for anyone who is not watching the Federal Register. TariffWatch is the keep-watching subscription for importers who already know their HTS codes.
