Post-de-minimis cost estimator

Assumptions and limits

Since 12:01 a.m. EDT on August 29, 2025, low-value shipments to the US (US$800 or less) no longer enter duty-free; non-postal shipments must be entered in CBP's ACE system by a party qualified to make entry, and applicable duties, taxes and fees apply (Federal Register 2025-16802, implementing Executive Order 14324).
Merchandise Processing Fee values are CBP's fiscal-year-2026 amounts, effective October 1, 2025 (CSMS #65741993). Exemptions for USMCA-originating goods are listed in CBP's MPF table; confirm eligibility with your broker.
Option A applies duty to the order value; Option B applies it to the bulk customs value. Postal-network shipments follow different duty rules and are not modelled.
Not included: additional tariffs that may apply to specific goods or origins, US state sales tax, income tax, currency conversion, insurance, returns, inventory financing, and the cost of stock sitting in two countries.
