Amino-resins; urea and thiourea resins, in primary forms

HS v2022 Code: 390910

About amino-resins; urea and thiourea resins, in primary forms

HS code 390910 covers the production of amino-resins, urea resins, and thiourea resins in their primary forms. These synthetic thermosetting plastics are widely used in a variety of industries, including construction, automotive, and furniture manufacturing. They offer excellent thermal and chemical resistance, making them a popular choice for applications that require durable and long-lasting materials.

Production process

The production of amino-resins, urea resins, and thiourea resins typically involves a polycondensation reaction between formaldehyde and various amine compounds, such as urea, melamine, or thiourea. The specific reaction conditions, including temperature, pressure, and the use of catalysts, can be adjusted to produce resins with different properties and characteristics.

Production inputs

The main raw materials required for the production of these resins are formaldehyde, urea, melamine, and thiourea. Additionally, various additives and modifiers may be used to enhance the resins' performance, such as fillers, plasticizers, and curing agents. The production process also requires specialized equipment, including reactors, mixing tanks, and drying or curing ovens.

Production outputs

The primary outputs of HS code 390910 are the amino-resins, urea resins, and thiourea resins in their primary forms, such as powders, granules, or liquids. These resins are then further processed and used as raw materials in the production of a wide range of products, including 392010 Laminates, 392020 Plastic plates, sheets, film, foil and strip, and 392030 Plastic monofilament, among others.
