Understand your shipment’s duty stack.

Enter your product and shipment. The tool stacks each duty layer and shows the math — nothing hidden, nothing presented as definitive.

1. Product & shipment

HTS code (10 digits)

The 10-digit Harmonized Tariff Schedule code for your product. Unsure? Ask a licensed broker — only CBP rulings bind.

MFN base rate

Best-effort live lookup of the MFN (base) rate from the public USITC tariff schedule. If it can't be reached from your browser, enter the rate manually from hts.usitc.gov.
