Harmonized Tariff Schedule

The Harmonized Tariff Schedule (HTS) is a standardized list of classification codes and corresponding duty rates used to identify imported goods for customs purposes, statistical reporting, and application of trade measures. Importers assign an HTS code to each product entry — for example, a shipment of men's cotton shirts is classified under a specific HTS code that determines the applicable duty rate and any import restrictions. Accurate HTS classification is essential because errors can lead to incorrect duties, shipment delays, or penalties.
