About the Duty Diligence: Landed Cost
Duty Diligence calculates the actual landed cost of every product after US import duty, showing you the real margin on each item. The app automatically reads the US tariff schedule twice daily and works out costs using the HS code, country of origin, and product cost already in your store.
No manual lookups or maintenance needed. The system excludes duties that are listed but no longer charged, and alerts you when dated changes will affect your products before they take effect. Click any duty rate to see the complete breakdown: base duty, additional layers, and exactly where each rate is set in the tariff schedule.
Launched: July 24, 2026
