Amino-resins; melamine resins, in primary forms

HS v2022 Code: 390920

About amino-resins; melamine resins, in primary forms

HS code 390920 covers amino-resins and melamine resins in their primary forms. These synthetic thermosetting plastics are widely used in a variety of industries, from furniture and construction to electrical and automotive applications. Their unique properties, such as high heat resistance, durability, and ease of molding, make them indispensable materials in the global manufacturing landscape.

Production process

Amino-resins and melamine resins are typically produced through a polycondensation process. This involves the reaction of formaldehyde with amino compounds, such as urea or melamine, under controlled temperature and pressure conditions. The resulting resin is then further processed, often through extrusion or injection molding, to create the desired primary forms, such as sheets, rods, or granules.

Production inputs

The main inputs for the production of amino-resins and melamine resins include formaldehyde, urea, melamine, and various catalysts and additives. Specialized machinery, such as reactors, extruders, and molding equipment, are also essential for the manufacturing process. Additionally, the industry relies on a steady supply of energy, water, and other utilities to maintain efficient production.

Production outputs

The primary outputs of HS code 390920 are the amino-resin and melamine resin products in their various forms.
