An HTS (Harmonized Tariff Schedule) code is a 10-digit number used to classify imported goods for customs and tariff purposes. Each product imported into the United States must be assigned an HTS code that determines its duty rate and eligibility under trade agreements.
The first six digits of an HTS code are based on the international Harmonized System (HS), while the final four digits are U.S.-specific subcategories. This global standard ensures consistent classification across borders.
How HTS Codes Work for Products
- Identify product attributes: Consider what your product is made of, how it’s used, and its form factor.
- Locate the appropriate chapter: Goods are organized by type — for example, textiles, electronics, or food products.
- Narrow by subheading: The subheading refines classification based on materials or use.
- Confirm the full 10-digit code: This determines the precise duty rate under U.S. customs law.
- Keep classifications current: Tariff codes change periodically, so it’s important to review them regularly.
Accurate classification ensures that duties are paid correctly and that shipments clear customs without delay.
