The current version is the 11th revision, effective from January 1, 2021.The classification system consists of four levels: large, medium, small, and detailed categories. The coding method uses English letters for the large category and 2, 3, and 4-digit codes for the medium, small, and detailed categories respectively. A "0" at the end of the code indicates similarity with the previous level, while a "9" indicates other categories.
