Tariff rates change fast in 2026. If something on this site looks stale or wrong, we want to hear about it — a sourced correction is the fastest way to get it fixed.

Report a rate error

Email [email protected] with the subject line "Rate correction". Please include the page URL, the rate you believe is wrong, and a link to the official source (USITC HTS, Federal Register, CBP CSMS, or a carrier's published fee schedule). Sourced corrections are typically updated within a week.

Suggest a category or corridor

We expand the category and country matrix based on demand. If you buy something we don't cover — toys, supplements, watches, a new origin country — tell us what and where from.

Business and partnerships

For forwarding services, customs brokers, or affiliate partnership inquiries, use the same address with the subject line "Partnership".

Please note: we cannot advise on your specific shipment, dispute a customs charge on your behalf, or classify a specific product. For that, contact your carrier or a licensed customs broker.
