Sodium carbonate (soda ash)
HS code 283620Formula Na₂CO₃
Soda ash is a base chemical for glass, detergents and water softening. Dense soda ash suits glass furnaces, light soda ash suits detergents and chemicals. In drilling it treats out calcium from the mud. We trade both, with a minimum purity of 99 %.
- Glass manufacturing
- Detergents and cleaners
- Water softening
- Chemical synthesis
