Cellulose acetates; non-plasticised, in primary forms

HS code 391211 covers the classification of cellulose acetates, a versatile and widely-used group of materials derived from cellulose. These non-plasticized cellulose acetates are produced in primary forms, making them a crucial raw material for a diverse range of industries, from textiles and plastics to pharmaceuticals and photography. As a key component in the global supply chain, the production and trade of cellulose acetates play a significant role in the broader economy.

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 acid and other reagents are used to replace the hydroxyl groups in the cellulose structure with acetyl groups. The resulting cellulose acetate is then purified and processed into various primary forms, such as flakes, granules, or powders, ready for use in downstream applications.

The primary inputs required for the production of HS code 391211 cellulose acetates include cellulose-rich raw materials, such as wood pulp or cotton linters, as well as acetic acid and other chemical reagents necessary for the acetylation process. Additionally, specialized production equipment, such as reactors, distillation columns, and drying systems, are essential for the manufacturing of these materials in primary forms.

Cellulose acetates produced under HS code 391211 are widely used as a raw material in the manufacture of a variety of products. These include 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392069 Other plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, and 391230 Cellulose acetates; plasticised. The versatility of cellulose acetates makes them a valuable input for industries ranging from textiles and packaging to pharmaceuticals and electronics.
