Adhesives; prepared, based on polymers of heading 3901 to 3913 or on rubber

HS code 350691 covers a wide range of prepared adhesives based on polymers or rubber. These adhesives play a crucial role in various industries, from manufacturing and construction to packaging and consumer goods. They are essential for bonding materials, sealing joints, and providing strong, durable connections. The adhesives industry is a significant contributor to the global economy, with a growing demand driven by technological advancements and the increasing need for efficient and reliable bonding solutions.

The production of adhesives under HS code 350691 typically involves a multi-step process. Manufacturers begin by selecting and combining the appropriate polymers, rubbers, and other raw materials to create the desired adhesive formulation. This is often done through mixing, blending, and chemical reactions to achieve the required properties, such as viscosity, tack, and curing time. The adhesive mixture is then processed, which may include steps like emulsification, dispersion, or solvent evaporation, depending on the specific adhesive type. Finally, the adhesive is packaged and prepared for distribution to various end-use industries.

The main inputs required for the production of adhesives under HS code 350691 include polymers (such as 3901 Polymers of ethylene, 3902 Polymers of propylene, and 3913 Polymers of natural polymers), rubbers, solvents, and various additives like plasticizers, thickeners, and curing agents. Manufacturers also rely on specialized machinery and equipment, such as mixers, extruders, and packaging lines, to ensure efficient and consistent production.

The adhesives produced under HS code 350691 are used in a wide range of applications, including 3506 Prepared glues and other prepared adhesives, not elsewhere specified or included, 3907 Polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms, and 4016 Other articles of vulcanized rubber other than hard rubber. These adhesives are essential for bonding materials in industries such as construction, automotive, packaging, and consumer goods, among others.
