The US lumber tariff in 2026 is driven mainly by Section 232 — a national-security measure that sits on top of the normal HTS duty. It applies at roughly 10% on raw and semi-finished lumber. The current structure took effect 2025.
The measure applies on the full customs value of covered goods and stacks on top of the base HTS duty and any country-level tariff layer, so the effective rate depends on where the goods are made as well as what they are.
Country of origin then layers on top: the same lumber shipment can cost far more from a higher-tier origin or one subject to Section 301 than from a USMCA partner. Enter your origin and value in the calculator above to see the base duty, the lumber measure and the country layer itemised — and confirm the final number with a customs broker before filing.
