Cellulose acetates; non-plasticised, in primary forms

HS v2017 Code: 391211

About cellulose acetates; non-plasticised, in primary forms

HS code 391211 covers the classification of cellulose acetates, a type of thermoplastic polymer derived from cellulose. These non-plasticized cellulose acetates are widely used in various industries, including textiles, plastics, and pharmaceuticals, due to their unique properties such as transparency, dimensional stability, and chemical resistance. As a key component in many consumer and industrial products, the cellulose acetates industry plays a vital role in the global economy.

Production process

The production of non-plasticized cellulose acetates typically involves a multi-step process. First, cellulose is extracted from natural sources, such as wood pulp or cotton linters. The cellulose is then chemically modified through an acetylation process, where acetic anhydride and acetic acid are used to replace the hydroxyl groups in the cellulose structure with acetate groups. The resulting cellulose acetate is then purified, dried, and extruded or molded into the desired primary forms, such as pellets or sheets.

Production inputs

The main inputs required for the production of non-plasticized cellulose acetates include cellulose raw materials, such as wood pulp or cotton linters, as well as chemical reagents like acetic anhydride and acetic acid. Additionally, specialized production equipment, such as reactors, extruders, and molding machines, are necessary to transform the raw materials into the final cellulose acetate products.

Production outputs

The primary outputs of HS code 391211 are non-plasticized cellulose acetate products in various primary forms, such as pellets, sheets, or flakes. These cellulose acetates are then consumed by a wide range of industries, including 54 Man-made filaments, 55 Man-made staple fibres, 39 Plastics and articles thereof, and 30 Pharmaceutical products.
