About dextrins and other modified starches (e.g. pregelatinised or esterified starches); glues based on starches or on dextrins or other modified starches

HS code 3505 covers a diverse range of modified starch products that have a wide variety of industrial and commercial applications. These materials are derived from natural starches and are used in numerous industries, including food processing, adhesives, textiles, and paper manufacturing. Their unique properties, such as improved viscosity, stability, and binding capabilities, make them essential ingredients in many products that are integral to the global economy.

Production process

The production of dextrins and other modified starches involves various chemical and physical processes that alter the structure and properties of natural starches. Common techniques include acid or enzyme hydrolysis, oxidation, esterification, and pregelatinization. These processes break down the starch molecules, creating smaller fragments with altered characteristics that can be tailored to specific applications.

Production inputs

The primary input for this industry is natural starch, which is typically derived from sources such as corn, wheat, potato, or tapioca. Manufacturers also require various chemicals, such as acids, bases, or enzymes, to facilitate the modification of the starch. Additionally, specialized equipment, such as reactors, driers, and milling machines, is necessary to carry out the production processes.

Production outputs

The main outputs of this industry are dextrins, pregelatinized starches, and other modified starches, which are used in a wide range of products. These materials may be further processed or incorporated into 3506 Prepared glues and other prepared adhesives, not elsewhere specified or included, 1901 Malt extract; food preparations of flour, groats, meal, starch or malt extract, not containing cocoa or containing less than 40% by weight of cocoa calculated on a totally defatted basis, not elsewhere specified or included, or 3809 (Finishing agents, dye carriers to accelerate the dyeing or fixing of dyestuffs and other products and preparations (for example, dressings and mordants), of a kind used in the textile, paper, leather or like industries, not elsewhere specified or included).
