Cellulose ethers; (other than carboxymethylcellulose and its salts), in primary forms

HS v2022 Code: 391239

About cellulose ethers; (other than carboxymethylcellulose and its salts), in primary forms

HS code 391239 covers a range of cellulose-based chemical compounds known as cellulose ethers. These materials are widely used in various industries, including pharmaceuticals, cosmetics, construction, and food processing, due to their unique properties such as thickening, emulsifying, and stabilizing capabilities. As a key component in many everyday products, the cellulose ethers industry plays a vital role in the global economy.

Production process

The production of cellulose ethers typically involves the chemical modification of cellulose, a naturally occurring polymer derived from plant materials. The main production techniques include etherification, where cellulose is reacted with organic compounds to form ether linkages, and purification processes to ensure the desired purity and quality of the final product.

Production inputs

The primary inputs for the cellulose ethers industry include cellulose, which is often sourced from wood pulp or cotton linters, as well as various chemical reagents and solvents used in the etherification and purification processes. Additionally, specialized production equipment, such as reactors, filtration systems, and drying units, are essential for the efficient and consistent manufacture of these materials.

Production outputs

Cellulose ethers produced under HS code 391239 are used in a wide range of applications, including 391231 Carboxymethylcellulose and its salts, 391232 Cellulose ethers in primary forms, and 391239 (Cellulose ethers; (other than carboxymethylcellulose and its salts), in primary forms). These materials are often incorporated into formulations for pharmaceuticals, cosmetics, construction materials, food additives, and various other products that require their unique functional properties.
