How Import Duty Is Calculated
The landed-cost estimate depends on classification, origin, and the customs value used for the entry.
1. HS Code Classification
Your product classification sets the base duty rate. Small mistakes can materially change the estimate.
2. Country of Origin
Origin changes eligibility for trade programs and additional tariffs, including Section 301 for some US imports.
3. Customs Value & Fees
The estimate applies the selected FY2026 entry-processing fee and adds the harbor fee only when you select a covered-port ocean movement.
The estimate is free. The insight keeps going.
Your duty is one number. Your supply chain is the whole story.
