US Tariff Rate Calculator

Chinese imports face multiple layers: (1) MFN base rate (varies by HS code, typically 0-20%), (2) Section 301 tariffs on listed goods (7.5%-100% depending on the list), and (3) Section 122 tariff at 10%, effective February 24, 2026. Use the tariff calculator to get the exact stack for your HS code.

Section 122 of the Trade Act is a 10% tariff on most US imports, effective February 24, 2026 and expiring July 24, 2026 (150-day authority). It replaced the IEEPA tariffs struck down by the Supreme Court on February 20, 2026. USMCA partners (US, Mexico, Canada) are exempt, as are products already subject to Section 232 (steel, aluminum, and their derivatives).

Yes. Goods manufactured in Mexico or Canada that qualify under USMCA rules of origin are fully exempt from the Section 122 tariff. USMCA qualification requires meeting the applicable rule of origin, which varies by product and HS code. The tariff calculator shows the full duty stack for USMCA-origin goods, including whether the exemption applies.

Section 301 is a China-specific tariff authorized under the Trade Act of 1974. It applies only to goods manufactured in China, with rates of 7.5%-100% depending on which list the product appears on. Section 122 is a global tariff of 10% that applies to imports from most countries, with exemptions for USMCA partners and Section 232 products. Both can apply simultaneously on China-origin goods.

MFN stands for Most Favored Nation. It is the base tariff rate that the US applies to imports from any WTO member country that has not negotiated a separate free trade agreement with the US. The MFN rate is the floor before any policy surcharges (Section 301, 232, 122) are added. Free trade agreement partners such as USMCA countries get preferential rates below the MFN rate.
