description: "Duty Diligence works out the landed cost of every product after US import duty and the margin it leaves you, from the cost, HS code and country of origin already on your products. There is nothing to look up and nothing to maintain. It reads the US tariff schedule twice a day, leaves out the duties that are still listed but no longer charged and tells you before a dated change reaches your products. Every rate opens to its working: the base duty, each layer on top and where it is written."
