Tariffs explained
The tariffs that actually change your duty
Section 301, Section 232 and the 2025–26 reciprocal actions stack on top of the base HTS rate. These hubs explain each one in plain English, with every figure sourced and dated.
China tariffs: what you actually pay to import from China in 2026
Most goods from China carry a Section 301 tariff on top of the normal HTS duty — and the $800 de-minimis exemption, suspended for China and Hong Kong first, is now suspended for every origin. Here's how the stack works, with every rate sourced.
Section 232 steel & aluminum tariffs, explained
Section 232 adds a national-security tariff to covered steel and aluminum articles — and, since 2025, a growing list of derivative products. Rates and scope changed repeatedly, so the verified-on date matters as much as the number.
