Magnesite should not contain any outside inclusions and objects.
Magnesite should be delivered by fractions in 1,0 TN plastic woven
containers with plastic cover, inside which there is a polythene bag.
The Magnesite should be loaded into railcars in strong serviceable
bags which must provide for the safety of the cargo during transshipment
and transportation.
