Q&A(FAQ) About HS Codes (Statistical Classification Numbers)
1. Overview of HS Codes
In international trade, HS codes (Harmonized System codes) are used as a global standard for customs duties, regulatory requirements, and statistical processing in each country.
HS codes are part of a universally recognized classification system. Incorrect classification can lead to the misapplication of tariff rates and potential customs clearance issues. Therefore, it is important to ensure a proper understanding and accurate use of these codes.
The HS code is a product classification system based on the Harmonized Commodity Description and Coding System established by the World Customs Organization (WCO).
- The first 6 digits are standardized worldwide
- Additional digits (typically 8 to 10 digits) are defined by each country
- The system is revised approximately every five years
Example: 8504.xx: Electrical equipment such as transformers and power supplies

3. Important Notes for Practical Use
HS codes are not merely classification numbers; they are critical information that affect tariffs, regulations, and overall trade operations. In particular, for power supply equipment, classification may vary depending on the application and configuration, requiring accurate determination from a technical perspective.
In addition, HS codes may be used to determine whether a product is subject to various regulations, such as China CCC certification or EU CE marking directives.
When customers export or import products, the final determination of the applicable HS code is the responsibility of the exporter. Therefore, it is recommended to consult with customs brokers or the relevant authorities as necessary.
