As far as I know, Pingdingshan Coal Group's coal is ok, but a large part of it is not exported, but processed by its own coal washing plant and coking plant. Only a few will be listed and traded in the coal trading hall of Pingdingshan Coal Industry Group at the intersection of Miner Road and Tiyu Road, and participants will bid and sign contracts according to the bidding situation. The whole process is fair. Of course, there is nothing absolutely fair now.

As for the reputation of Pingdingshan Coal Group, I can only say that it is good on the whole, but I can't deny the influence of some people's personal behavior on the company's image. Moreover, different interests will lead to such a result.

If there is a problem that your calorific value does not match, I will give you a suggestion, that is, keep the sample for future reference, and both parties are present when sealing it for future reference, so that any dispute can be recorded; If the calorific value does not match, it can be deducted and settled according to the contract to ensure its own interests.

I hope my answer is helpful to you.
