Should special purchases be included in the material rejection rate?

Yes Special procurement is also the materials purchased under special conditions. Generally, it refers to the process of receiving materials urgently when the incoming materials do not meet the requirements or the quality is unknown.

Under normal circumstances, try not to carry out special mining, which is not only difficult to guarantee the quality of enterprises, but also troublesome to operate in the management system, because it has been operated by several departments.
