HS v2017 Code: 3505

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 products, which include dextrins, pregelatinized starches, and starch-based glues, play a crucial role in various manufacturing processes and consumer goods. As a key component in the food, paper, textile, and adhesive industries, the 3505 product group is an essential part of the global economy.

Production process

The production of HS 3505 items typically involves the chemical or physical modification of native starches. This can include processes like acid or enzyme hydrolysis, oxidation, esterification, or pregelatinization. These treatments alter the molecular structure and properties of the starch, yielding products with unique characteristics suited for different applications. For example, dextrins are produced by the partial hydrolysis of starch, while pregelatinized starches are made by cooking and drying starch to improve its solubility and thickening abilities.

Production inputs

The main raw material input for HS 3505 products is native starch, which is typically derived from sources like corn, wheat, potato, or tapioca. Other key inputs include various chemicals and enzymes used in the modification processes, as well as specialized production equipment like reactors, dryers, and milling machinery. Energy, water, and labor are also important resources required for the manufacturing of these starch-based products.

Production outputs

The outputs of HS 3505 include a wide range of modified starches and starch-based adhesives. These products find use in numerous downstream industries, such as 1901 Food preparations, 4810 (Paper and paperboard, coated on one or both sides with kaolin (china) or other inorganic substances, with or without a binder), 5903 Textile fabrics impregnated, coated, covered or laminated with plastics, other than those of heading 5902, and 3506 Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg. The modified starches can also be used as thickeners, binders, or texturizers in a variety of consumer and industrial products.
