Industrial Bases from China

Sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, ammonia solutions, and other industrial bases.

Industrial bases are the alkaline workhorses of industrial chemistry, caustic soda (sodium hydroxide) for pulp and paper, soap and detergent, alumina production, and chemical synthesis; potassium hydroxide for biodiesel, soft soap, and battery electrolytes; soda ash (sodium carbonate) for glass, detergent, and chemical manufacturing; sodium bicarbonate for food, pharmaceuticals, and animal feed; ammonia solutions for refrigeration, fertilizer chemistry, and water treatment.

Most industrial bases are Class 8 DG corrosive cargo. Caustic soda in flake or pearl form (50% NaOH equivalent in solid) and in 32 to 50 percent aqueous solution are both Class 8 PG II, strict UN packaging requirements (Y-coded drums or IBCs), full DG documentation chain, careful loading supervision. Soda ash and sodium bicarbonate are non-DG and ship in 25 kg paper bags or 1 MT jumbo bags.

China is the dominant global producer of caustic soda and soda ash, with the major factory clusters in Shandong, Jiangsu, Tianjin, and Hebei. Producer selection drives quality consistency, caustic soda spec parameters (NaOH content, sodium chloride impurity, iron content, sodium chlorate residue) vary materially between producers, and certain end uses (rayon production, alumina precipitation, food-grade applications) need producer-specific qualification.
