HTS Code Lookup: US Tariff Codes and Duty Rates

The Harmonized Tariff Schedule of the United States (HTS or HTSUS) is the list of codes and duty rates for every product imported into the US. Every entry needs a 10 digit HTS code, and that code decides the duty you pay. Search it here by product words or by code.

How an HTS code is built

Digits	Name	Example (6109.10.00.12)	Set by
2	Chapter	61: knitted clothing	World Customs Organization (HS)
4	Heading	6109: T-shirts, singlets, tank tops	HS, the same in every country
6	Subheading	6109.10: of cotton	HS, the same in every country
8	Tariff rate line	6109.10.00: where the duty rate is printed	United States
10	Statistical suffix	6109.10.00.12: men's	United States, for trade statistics

The first six digits are the international HS code that your supplier abroad may already use. The AI HS code finder suggests those six digits from a plain description; this lookup then gives you the US digits and the rate.

The three rate columns

• General (column 1): the normal rate for goods from most countries.
• Special: lower rates for goods that qualify under a free trade agreement or a preference program. The letters in brackets say which, for example S for USMCA, KR for Korea, AU for Australia. The goods must meet that program's rules of origin.
• Column 2: higher rates for countries without normal trade relations, currently Cuba, North Korea, Russia and Belarus.

Extra duties in chapter 99

On top of the HTS rate, chapter 99 adds duties for particular origins or goods: Section 301 duties on many goods from China, Section 232 duties on steel, aluminium and other products, and other trade actions. When a code's footnotes point to chapter 99 headings, they are listed with their extra percent. Many of these measures apply by country of origin without a footnote, and they change often, so check the current position before you ship.

Getting the classification right

The importer is responsible for the code. Classify by what the product is made of, what it does and how it is presented, read the section and chapter notes, and for a doubtful product ask a licensed customs broker or request a binding ruling from US Customs and Border Protection (CBP). Put the final code on your commercial invoice. Exporting from the US? Export codes (Schedule B) share the same first six digits.
