I visited a magnesium sulfate factory last year. The factory was large, the on-site management seemed good, and the products looked very nice—everything seemed perfect.
However, when I saw samples displayed in their office labeled 25-5, 25-14, and 25-18, I was actually quite worried.
Because this made me unsure: if I ordered a 25-20 content, would they ultimately deliver genuine 25-20, or 25-14, 25-18, or even a lower specification?
The factory said they can produce any specification the customer requires. However, in my view, there should really only be two main standards: General Standard – for regular use, meeting basic quality requirements. Premium Standard – for higher-end applications, with stricter quality specifications. #MagnesiumSulphate #Kieserite
