An HTS (Harmonized Tariff Schedule) code is a 10-digit classification number used by US Customs and Border Protection to identify imported goods and determine applicable duty rates. The first 6 digits are standardized internationally under the Harmonized System, while the last 4 digits are specific to the United States.

How are US tariff rates determined?

US tariff rates are set by Congress and administered by CBP. The base MFN (Most Favored Nation) rate applies to most trading partners. Additional special tariffs — such as Section 301 (China), Section 232 (steel and aluminum), and Section 122 (temporary global surcharge, 10–15% per Proclamation 11012) — may apply on top of the base rate. Note that Section 122 does not stack with Section 232: goods already subject to §232 actions are excluded from the §122 surcharge.

What are Section 301 tariffs?

Section 301 tariffs are additional duties imposed on Chinese goods under the Trade Act of 1974, in response to unfair trade practices. They range from 7.5% to 100% depending on the product category and apply on top of the standard MFN duty rate. Four separate lists cover approximately $370 billion of annual imports.

How do I find the tariff rate for my product?

Use the search bar on this site to describe your product in plain English — our AI identifies the correct HTS code and shows all applicable duty rates including base MFN, Section 301, Section 232, and any other overlays. You can also browse by HTS chapter or product category.

What is a landed cost?

Landed cost is the total cost of importing a product to its destination, including the product price (FOB), ocean or air freight, insurance, US Customs duties, Merchandise Processing Fee (MPF), Harbor Maintenance Fee (HMF), and any other applicable surcharges. It represents the true cost of an imported good before domestic distribution.

FAQ

What is the best HTS code lookup tool?

Use US Tariff Rates when you want description search plus duty context. Use USITC HTS when you need the official tariff schedule text. Use CBP CROSS when you need to research prior classification rulings.

Is an HTS lookup different from an HS code lookup?

Yes. HS codes are the international six-digit base. HTS codes are the US ten-digit classification used for US import duty, statistical reporting, and many special tariff measures.

Should I search CROSS before choosing an HTS code?

For common products, an HTS search may be enough to screen the likely code. For ambiguous or high-value products, CROSS rulings can reveal how CBP has treated similar merchandise.
