HS was officially implemented on 1988 65438+ 10/day, and revised every four years 1 time. More than 150 countries in the world have used HS, and more than 90% of the global trade goods are classified by HS. The overall structure of HS includes three parts: classification rules; Description of classes, chapters and subheadings; Codes and regulations for sequentially arranged items and sub-items. These three parts are the legal provisions of HS, which have strict legal effect and strict logic. HS first lists six general rules of classification, and specifies the classification principles and methods that must be followed when using HS to classify commodities. Many categories and chapters of the Harmonized System are marked with notes (category notes, chapter notes or subheading notes) at the beginning, which strictly stipulate the scope of goods classified into this category or chapter, and explain in detail the definition of technical terms in the Harmonized System or the technical standards and boundaries for distinguishing certain goods.
