The basic principles that should be followed when compiling commodity identification codes include the following three aspects: 1, the principle of uniquenessCommodities of the same commodity item should be assigned the same commodity identification code. Commodities with the same basic characteristics are regarded as the same commodity item, and commodities with different basic characteristics are regarded as different commodity items (the basic characteristics of commodities mainly include commodity name, commodity trademark, type, specification, quantity, packaging type, etc.).Commodities of different commodity items should be assigned different commodity identification codes. 2, the meaningless principle. Each digit in the product identification code does not indicate any specific information about the product. 3, the principle of stability. Once the commodity identification code is assigned, it should remain unchanged provided the basic characteristics of the commodity have not changed.
