The "qualification information verification" of State Grid Corporation of China is not a "prequalification", and suppliers voluntarily apply to participate in the verification, but it is not mandatory for suppliers to participate. The qualification information verification has nothing to do with the so-called "shortlisting", "joining" and "qualified suppliers".

the purpose of supplier qualification information verification conducted by state grid co., ltd. is to fully understand whether potential suppliers have the qualification and ability to produce qualified products, establish and improve the supplier information base, and help suppliers understand the gap between their own qualification and the requirements of the supplier qualification information verification specification of state grid co., ltd., so as to improve and improve them in a targeted manner, reduce the repetitive work of suppliers in making bidding documents, and further improve the efficiency of bid evaluation.
