The rates in this summary are the full program rates as the calculator computes them; one or more may not apply to your shipment — the conditions are noted below.
Imports from China carry a combined tariff of approximately 50%, driven entirely by the Section 301 (sector) tariff that took effect January 1, 2025. The MFN base rate is free, so the Section 301 (sector) charge makes up the full duty. This 50% rate replaces rather than stacks on any earlier Section 301 List rate for the same code. On a $1,000 shipment, duties run approximately $500.
