Want to understand the full formula behind these numbers? Read our guide to how tariffs are calculated in 2026, including tariff stacking across MFN, Section 122, Section 301, and Section 232 layers. The April 2026 Section 232 restructuring moved to full customs value basis, and the Section 301 investigation may add new tariff layers — rates are changing fast. If you import from USMCA countries, check whether your goods qualify for preferential rates with our USMCA certificate of origin guide. If the total duty estimate seems high, consider a bonded warehouse to defer payment for up to 5 years. Note that Section 122 tariffs expire July 24, 2026 — the CAFC stay and statutory sunset make this a critical planning window. For UK imports, standard MFN rates apply (no FTA), while Australian imports often qualify for AUSFTA duty-free rates. To legally reduce the customs value your duties are calculated on, learn about CBP's six customs valuation methods and the first sale rule which can cut duties 10-30% by using the manufacturer's price instead of the middleman's.
