Product standard numbers can be found on the website of the National Standardization Administration. Product standards are technical specifications formulated for products. In my country, there are four types of technical specifications formulated for products: national standards, industry standards, local standards and enterprise standards.

According to the "Standardization Law of the People's Republic of China", if there are corresponding national standards, enterprises should implement them in accordance with national standards; if there are no national standards, enterprises can implement enterprise standards or local standards. Each product standard will correspond to a number, which is the product standard number.

Product standards are standards established to ensure the applicability of products and set some or all of the requirements that products must meet. Product standards are the technical basis for product production, inspection, acceptance, use, maintenance and trade negotiations. They are of great significance for ensuring and improving product quality and improving the economic benefits of production and use.
