Glues; based on starches, or on dextrins or other modified starches

HS code 350520 covers a range of adhesive products derived from starches, dextrins, and other modified starches. These glues are widely used across various industries, including manufacturing, construction, and packaging, due to their strong bonding properties, versatility, and cost-effectiveness. As a crucial component in many supply chains, the production and trade of these glues play a significant role in the global economy.

The production of HS code 350520 glues typically involves the modification of natural starches, such as corn, wheat, or potato starch, through processes like hydrolysis, oxidation, or esterification. These techniques alter the molecular structure of the starch, enhancing its adhesive properties. The modified starch is then combined with other ingredients, such as water, preservatives, and thickeners, to create the final glue product.

The main inputs required for the production of HS code 350520 glues include raw starch materials, such as 100300 Barley, 100190 Wheat, and 110812 (Maize (corn) starch). Additionally, manufacturers may utilize various chemicals and additives, such as 290511 (Methanol (methyl alcohol)), 380810 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, and 391710 (Tubes, pipes and hoses, and fittings therefor (for example, joints, elbows, flanges), of plastics). Specialized production equipment, such as mixers, extruders, and drying systems, are also essential for the manufacturing process.

The primary output of HS code 350520 is a range of adhesive products, including general-purpose glues, specialty adhesives, and industrial-grade bonding agents. These glues find applications in various industries, such as 940320 Furniture; metal, 391810 Plates, sheets, film, foil and strip, of plastics, and 481910 Cartons, boxes and cases, of corrugated paper or paperboard. The versatility of these glues allows them to be used in a wide array of manufacturing, construction, and packaging processes.
