Which cement plants in Pingxiang produce PO425?

I sell cement. According to my actual purchasing experience, there are mainly four cement plants that produce PO425.

Pingxiang taichang cement manufacturing co., ltd

Pingxiang sinoma cement co., ltd

Pingxiang south cement co., ltd

Pingxiang yinshantai cement co., ltd.

Among them, Sinoma and the South are central enterprises, and Yinshan Taihe Taichang Cement is a private enterprise.

In fact, the quality is comparable, but the price is quite different. Taichang cement is the cheapest, followed by Yinshantai. Central enterprises are very cattle, and ordinary people can't buy them directly from factories, but only through dealers, so they are very expensive.
