The tax number in the tariff is the commodity code of the customs. For a country or region, the tariff code is the same as the Harmonized System code. However, different countries and regions may have different Harmonized System codes. HSCODE is a universal commodity code of the World Customs Organization, which has also been adopted by China Customs. However, the commodity code of US Customs is HTSCODE, which is the same as the first six digits of HSCODE, but the last few digits are different. That is to say, China's TARIFFCODE is the same as HSCODE, and American TARIFFCODE is the same as HTSCODE, but it is different from HSCODE. HS codes can be found on stereo search.
