Does exported gypsum have higher quality?

In most cases, exported gypsum has a higher quality compared to regular domestic gypsum because the factory must adhere to stricter standards. As a result, exported gypsum is often whiter, has a finer and more uniform grain size, contains fewer impurities, has greater strength, and comes in more durable packaging. (The bags for regular market gypsum are made of polypropylene, while the exported gypsum bags are of the ADSTAR type.)
