Overview
- The Bureau of Industry and Security added 407 HTS codes to the list of derivative products subject to Section 232, applying a 50% duty to the steel and aluminum content of entries from 12:01 a.m. ET on Aug. 18 with no in‑transit exemptions.
- The expanded list spans wind turbines, mobile cranes, bulldozers, railcars, appliances, compressors, pumps, furniture, baby gear, tableware, and specific auto and EV components such as exhaust parts and electrical steel.
- Officials published the additions only as 10‑digit customs codes, creating immediate compliance challenges for importers and brokers and raising questions about how these levies interact with country‑specific tariffs.
- Analysts estimate roughly $320 billion of imports are now affected, with research notes warning of higher production costs that could filter into prices across autos, construction, electronics and household goods.
- U.S. steelmakers including Cleveland‑Cliffs praised the move as closing loopholes, while automakers and Tesla flagged limited domestic capacity for certain specialty steels and the Treasury signaled tariff revenue will rise substantially.
