When handling a foreign trade order, I learned that an HS code is needed for customs clearance procedures.
After searching on Google, I finally understood what an HS code is. Haha, sorry to embarrass the experts of foreign trade.
An HS code is also known as a customs code, which stands for the Harmonized System of Coding.
The Harmonized System of Coding was developed by the International Customs Council. Its English name is The Harmonization Code System (HS-Code).
There are 22 major categories and 98 chapters in the HS coding system. The internationally recognized HS codes consist of 2-digit, 4-digit, and 6-digit codes. Codes beyond 6 digits and their corresponding goods are determined by each country individually.
Since January 1, 1992, China's import and export tariff schedule has adopted the World Customs Organization's "Harmonized System of Nomenclature and Coding" (abbreviated as HS). This system is a scientific and systematic international trade commodity classification system, using a six-digit code. It is applicable to various aspects such as tariffs, statistics, production, transportation, trade control, inspection and quarantine. Currently, over 90% of global trade volume uses this catalog, making it a standard language of international trade. China's import and export tariff schedule adopts a ten-digit code, with the first eight digits being equivalent to the HS code, and the last two digits being China's subheadings. These two digits are an extension based on the classification principles and methods of the HS system, according to the actual situation of China's import and export commodities.
