Production of B-grade soda ash having following characteristics is allowed : mass fraction of sodium carbonate - not less 97%, mass fraction of sodium carbonate in not incinerated product – not less 94%, mass fraction for loss of incineration at 270-300 °C  – not more 3%, mass fraction of chlorides as NaCl – not more 1.5%, mass fraction of iron as Fe2O3 – not more 0.03%. Commercial – grade soda ash is classified as moderate hazardous product. Soda ash is packed up in polypropylenes 40 kg bags . Soda ash packed up in bags is shipped by all transport means having a cover. Non-packed soda ash is loaded in bulk and shipped by specialized vehicle (soda ash carbon blank distributors, cement tank wagons).
