Polyurethanes; in primary forms

HS v2017 Code: 390950

About polyurethanes; in primary forms

HS code 390950 covers polyurethanes in their primary forms, which are a versatile class of polymers with a wide range of applications. Polyurethanes are used extensively in the manufacturing of various products, including foams, coatings, adhesives, and elastomers. This industry plays a crucial role in the global economy, providing essential materials for industries such as construction, automotive, and consumer goods.

Production process

The production of polyurethanes in primary forms typically involves a step-by-step process. The key steps include the reaction of a polyol (a compound with multiple hydroxyl groups) with a diisocyanate (a compound with two isocyanate groups) to form the polyurethane polymer. This reaction is often catalyzed and can be tailored to produce a wide range of polyurethane products with different properties and characteristics.

Production inputs

The main inputs required for the production of polyurethanes in primary forms include polyols, diisocyanates, and various additives such as catalysts, surfactants, and blowing agents. These raw materials are sourced from the petrochemical industry and are essential for the manufacturing process. Additionally, specialized equipment and machinery, such as reactors, mixers, and extruders, are necessary for the efficient production of polyurethane materials.

Production outputs

The primary outputs of the polyurethane industry covered by HS code 390950 are various polyurethane products in their raw, unfinished forms. These materials can be further processed and transformed into a wide range of end-use products, including 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392690 Other articles of plastics and articles of other materials of headings 3901 to 3914, and 401699 Other articles of vulcanized rubber other than hard rubber, among others.
