About amino-resins, phenolic resins and polyurethanes, in primary forms

HS code 3909 covers a diverse range of synthetic resins that are widely used in various industries. These materials, including amino-resins, phenolic resins, and polyurethanes, are essential building blocks for a multitude of products, from construction materials to automotive components. Their versatility and unique properties make them indispensable in the global economy, contributing to the development of innovative solutions across numerous sectors.

Production process

The production of amino-resins, phenolic resins, and polyurethanes typically involves a series of chemical reactions and polymerization processes. Amino-resins are commonly synthesized through the condensation of formaldehyde with urea, melamine, or other nitrogen-containing compounds. Phenolic resins are produced by the reaction of phenol or other phenolic compounds with formaldehyde. Polyurethanes are created by the reaction of polyols (such as polyether or polyester) with isocyanates, often in the presence of catalysts and other additives.

Production inputs

The primary inputs for the production of HS code 3909 materials include a variety of raw materials, such as formaldehyde, urea, melamine, phenol, polyols, and isocyanates. Additionally, manufacturers may utilize specialized equipment, including reactors, mixing vessels, and extrusion or molding machines, to facilitate the production processes. The availability and cost-effectiveness of these key inputs can significantly impact the competitiveness of the industry.

Production outputs

The outputs of HS code 3909 are diverse and find applications in a wide range of industries. Amino-resins, phenolic resins, and polyurethanes are used in the production of 3920 Plastics and articles thereof, 3921 Other plates, sheets, film, foil and strip, of plastics, 3912 Cellulose and its chemical derivatives, not elsewhere specified or included, in primary forms, and 3914 Ion-exchangers based on polymers of headings 3901 to 3913, in primary forms, among others. These materials contribute to the manufacturing of adhesives, coatings, foams, and a variety of molded or extruded products, making them essential components in the global supply chain.
