Show HN: Lookup U.S. import duties and tariffs in seconds

2 points by minhtripham 7 months ago · 2 comments · 1 min read

The official U.S. tariff database is hard to navigate.

I built a simple tool to help importers look up duty rates and stay on top of the ever-changing tariff landscape.

TariffMath lets you look up U.S. import duties by HTS code and country of origin. It includes Base MFN duty rates and Overlay tariffs like Section 301, Liberation Day, fentanyl-related penalties etc.

Would love feedback on what’s missing or confusing. You can try it at https://tariffmath.com

Thanks!
