What is an HS code, and how it differs from HTS

Six digits are shared by most countries, and the rest is national. Type six digits to see what the US adds.
| Code | Line | General | Column 2 |

An HS code is the six-digit number in the Harmonized System, a nomenclature of the World Customs Organization. Past those six digits, the tariff is national. The United States adds four for imports, in the Harmonized Tariff Schedule, known as the HTS code, and uses another extension for exports, called Schedule B. So a code printed on a foreign invoice is a hint and not an answer, and only the US line carries a US rate. As an example, 6109.10 is a T-shirt of cotton worldwide, and the US adds 6109.10.00 with a rate of 16.5%. Under 19 U.S.C. 1484, the importer of record must use reasonable care in entering goods, whoever suggested the number. Rates are from 2026 HTS Revision 22.

Why the code matters
It sets the ordinary rate and the lists. For example, a cotton knit T-shirt is $3,650 (36.5%) on $10,000 from China in this calculator. A similar shirt in man-made fibers is $5,200 (52%). These two lines start with the same four digits and differ in fiber.
How to go from a foreign code to a US one
Take the first six digits of the code your supplier gave you. Enter them in the search above. Read each US line below that family, and pick the one that matches your goods in every word. If none fits, your supplier’s six digits may be wrong, or the two countries may classify the good differently. Go back to the heading text and the notes. In a close case, CBP’s rulings database shows how similar goods were treated.
Rights in the nomenclature
The World Customs Organization’s site marks its content as its copyright, and we could not read its terms. What we show comes from the US tariff, which is US law.
