See every featureDuty 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.
MarginGuard helps merchants see whether promotions are still profitable. It combines product inputs, packaging, fulfillment, payment fees, discounts, ad spend, refunds, and shipping subsidies into order- and SKU-level margin views. Use the analytics center, profit analysis, simulator, and trend dashboards to spot untracked items, risky promotions, low-margin products, and profit leaks before campaigns go live.
