Calculate import duties with full tariff stacking breakdown
Tariff data as of March 2026Get a quote from a licensed customs broker for binding HTS classification and duty optimization.
US import duties in 2026 are not a single rate. They are multiple layers of tariffs added together (not compounded). Your goods may be subject to a base MFN duty, plus Section 301 surcharges (China), Section 232 (steel/aluminum), and the new Section 122 global surcharge (10%, post-SCOTUS). This tool calculates all layers for you.
De minimis (19 USC 1321) allowed packages valued at $800 or less to enter the US without paying any import duties. This exemption was widely used by e-commerce platforms like Shein, Temu, and AliExpress. In 2025-2026, the exemption was first suspended for China, then for all countries, and finally permanently repealed by Congress.
With Section 301 tariffs adding up to 25% on Chinese goods and the new Section 122 applying 10% globally, many importers are evaluating alternative sourcing countries like Vietnam, India, Thailand, and Mexico. This comparison helps you quantify the cost difference for the same product from different origins.
Section 122 of the Trade Act of 1974 authorizes the President to impose temporary import surcharges of up to 15% for up to 150 days to address balance-of-payments emergencies. After the Supreme Court struck down IEEPA tariffs on Feb 20, 2026, the administration invoked Section 122 to impose a uniform 10% surcharge on all imports. Unlike the previous IEEPA tariffs (which had different rates per country), Section 122 applies a flat rate globally.
Section 301 of the Trade Act of 1974 authorizes the US Trade Representative to retaliate against unfair foreign trade practices. The China Section 301 tariffs were first imposed in 2018 across four "Lists" of products. These tariffs remain in effect because they have separate legal authority from the IEEPA tariffs struck down by SCOTUS.
Section 232 of the Trade Expansion Act of 1962 authorizes tariffs on imports that threaten national security. Currently, 25% tariffs apply to steel imports and steel derivative products face 50% tariffs. Some countries (Australia) have full exemptions, while others (EU, Japan, UK) have tariff-rate quotas.

Rates are based on HTS (Harmonized Tariff Schedule) codes and country-specific trade agreements, executive orders, and Section 301/232 actions. The final rate is often a stack of a base MFN rate plus one or more additional tariff layers.

Previously, packages valued under $800 entered the US duty-free under the de minimis rule. This exemption was eliminated for goods from China in May 2025, and for all countries in August 2025. All shipments now require formal entry and duty payment.
