Guangxi Materials Group may have belonged to a subordinate unit of Guangxi Materials Bureau. In the 1990s, the original planned material allocation function disappeared with the market economy, and the material bureau system was completely abolished, and the personnel were assigned to the commercial department. All subordinate state-owned enterprises are under the centralized management of SAAC, so according to the normal hierarchical management, the department level of SAAC and subordinate enterprises are taken as the reference department level.
Therefore, Guangxi Material Group may be at the department level.
