Glycerol, crude; glycerol waters and glycerol lyes

HS v2017 Code: 1520

About glycerol, crude; glycerol waters and glycerol lyes

HS code 1520 covers the trade and production of glycerol, a versatile chemical compound with a wide range of industrial and commercial applications. Glycerol is a colorless, odorless, and viscous liquid that is commonly derived as a by-product of the soap and biodiesel manufacturing processes. It plays a crucial role in various industries, including food, pharmaceuticals, personal care, and industrial chemicals, making it an important component of the global economy.

Production process

The primary production technique for glycerol involves the saponification of fats and oils, which is the chemical process of breaking down triglycerides into fatty acids and glycerol. This process is commonly used in the production of soaps and biodiesel. Glycerol can also be produced through the fermentation of carbohydrates or the hydrolysis of fats and oils. The crude glycerol obtained from these processes is then further refined and purified to meet the specific requirements of different industries.

Production inputs

The main inputs required for the production of glycerol include fats, oils, and other triglyceride-rich feedstocks, as well as water, chemicals, and energy sources for the saponification, fermentation, or hydrolysis processes. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the production and refining of glycerol.

Production outputs

The primary output of HS code 1520 is crude glycerol, which can be further refined and processed for use in a variety of applications. Refined glycerol is used in the production of 2905 Acyclic alcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives, 3823 Industrial monocarboxylic fatty acids; acid oils from refining; industrial fatty alcohols, and 3824 Prepared binders for foundry moulds or cores; chemical products and preparations of the chemical or allied industries, not elsewhere specified or included.
