Harmonized System Code

The first six digits of a US HTS code are the HS code, so they match across most countries. When shipping internationally, use the HS code on customs forms and let the destination country's longer code set the duty.

What is the difference between an HS code and an HTS code?

An HS code is the six-digit international base classification. The US HTS code adds four more digits, eight for the tariff line and two statistical, to set US duty rates.

• Harmonized Tariff ScheduleThe US system of product classification codes (based on the international Harmonized System) that determines duty rates for imports.
• Commercial InvoiceThe seller's invoice for an international shipment that lists the parties, goods description, quantity, value, currency, country of origin, and sale terms, used by customs to assess duties.
• Country of OriginThe country where goods were wholly produced or, for goods with inputs from several countries, last substantially transformed into a new article with a new name, character, or use.
• Customs BrokerA licensed professional who files entries with US Customs and Border Protection and calculates duties on behalf of importers.
