Questions, corrections, or feedback — we'd like to hear from you.
This site is maintained by a small, independent team, so we read every message that comes in. Before writing in, it may be worth checking whether your question is already covered:
- General questions about how duty, MPF, and HMF are calculated are answered in ourhomepage FAQ.
- Questions about what this tool is (and isn't) — including its limits as an estimate rather than an official customs determination — are covered in ourCustoms Compliance Disclaimer.
Email us
For everything else — a duty rate that looks wrong, a bug in the calculator, a partnership inquiry, or general feedback — reach us by email:
We aim to respond within a few business days. Please note that we can't provide binding guidance on your specific shipment's classification or duty rate — for that, consult a licensed customs broker.
Reporting a data error
If you spot an incorrect baseline duty rate, trade-program status, or Section 321 note on one of ourcountry-specific calculator pages, please include the country name and a link or citation to the source you're comparing against — that helps us verify and correct it quickly.
