CBP fees & fallback overlays (editable)

Duty rates (MFN, Section 301/232/122) come live from the US Tariff Rates API via this site's proxy. The fees below are added on top and computed locally; the overlay rates are only used if the live API is unreachable.

MPF rate (%) MPF minimum ($) MPF maximum ($) HMF rate (ocean only) (%) Fallback: Section 301 China (%) Fallback: Section 232 steel/alum (%) Fallback: Section 122 reciprocal (%)

Landed Duty Estimate

Enter an HTS code and shipment details, then click Calculate Duties.

Duty rates are pulled live from the US Tariff Rates API through this site's own secure proxy — the API key stays on the server and is never exposed. Rates stack the MFN base with Section 301 (China), Section 232 (metals), and Section 122 reciprocal surcharges, each cited to its Federal Register source. CBP user fees (MPF, HMF) are added on top using the editable assumptions. If the live API is unreachable, the tool falls back to the free USITC schedule plus the editable overlay rates. All figures are estimates for planning only and depend on product-specific exclusions, AD/CVD orders, and entry date. Not for filing — confirm with a licensed customs broker or CBP.
