A duty is a customs fee charged on goods that cross a national border. Its amount may depend on factors such as the goods’ value, type, origin, or applicable import rules. In cross-border e-commerce, duties can affect the final price and must be calculated and presented accurately.
Duty is not itself a cybersecurity threat, but handling it relies on connected checkout, payment, and customs systems. Incorrect or manipulated item data can produce wrong charges, while attackers may exploit weak integrations or impersonate customs services in payment scams. Businesses can reduce risk by validating shipment data, securing interfaces between systems, limiting access to pricing rules, and clearly showing charges before purchase.
