How to Check HTS Code of Your Products and Corresponding Tarriff Rate?


HTS stands for Harmonized Tariff Schedule. Based on HTS, all cargo entering USA will be subject to US import classification,Tarriff, documentation and electronic applications of US Custom. HTS is established on the basis of HS System, which is the Harmonized Commodity Description and Coding System formulated by the World Customs Organization in January 1989.

The first way to lookup for HTS code is to directly check on the HTS official website , type product name and search query. If there is no feedback of the product name, we can try to search for the product’s material, function, composition and structure.

The second way is: firstly find the first 6-digit HS code of the product, and then find the 4-digit code subdivided after HTS. The first 6 digits of HTS and Schedule-B are Same, they are both based on HS coding. So Schedule-B is a good source to refer.

Apart from Schedule-B code of the US Bureau of Statistics, there are other ways to check the first 6 digitals. You can find the accurate 6-digit product code from the UN Comtrade Database product list in the order of chapters, items, and sub-items. Commodity HS code of China’s export declaration is also a good source since China and USA are largest trading partners all over the world.

TAX, One thing to note here is that what is really valid in the US tax law is the first 8 numbers. In the 10-digit HTS code, the last two digits are the suffix numbers used for statistics, which actually have no substantial impact on the tax.

In fact, the difficulty of finding the accurate customs HTS code of a product lies in finding the last 4-digits. When the product classification category is particularly detailed, it is very easy to make mistakes. Also as mentioned before, last 4 digits varis in customs from different countries. Let’s take #NOxsensor as an example.

In China Custom, HS code of Nitrogen Oxide sensor is 9027100090. If we directly copy and paste all 10 digits into HTS website it will show empty result as below.
