How do I calculate import duties on my products?

Duty = Taxable Value × Duty Rate. The taxable value depends on valuation method (FOB or CIF) and the rate depends on your HS code in the destination country. Rates vary hugely: US clothing 10-32%, electronics 0-5%. Swap's Tariff Calculator lets you estimate landed cost before entering a market, and Swap Global calculates automatically at checkout.
