About amino-resins; n.e.c. in heading no. 3909, in primary forms, other than poly(methylene phenyl isocyanate) (crude mdi, polymeric mdi)

HS code 390939 covers a category of synthetic resins known as amino-resins, which are widely used in various industries. These resins are valued for their versatility, durability, and ability to impart specific properties to the final products. They find applications in coatings, adhesives, molded parts, and a range of other industrial and consumer goods, making them an essential component of the global manufacturing landscape.

Production process

Amino-resins are typically produced through a condensation reaction between an amino compound, such as urea or melamine, and an aldehyde, commonly formaldehyde. This process involves carefully controlling temperature, pressure, and reaction time to ensure the desired molecular structure and properties are achieved. The resulting resin is then further processed, often through additional polymerization or modification steps, to meet the specific requirements of the target application.

Production inputs

The primary raw materials required for the production of amino-resins under HS code 390939 include amino compounds (e.g., urea, melamine), aldehydes (typically formaldehyde), and various catalysts and additives. Additionally, specialized production equipment, such as reactors, mixing vessels, and drying systems, are essential for the manufacturing process. The availability and cost-effectiveness of these inputs can significantly impact the overall competitiveness of the amino-resin industry.

Production outputs

Amino-resins produced under HS code 390939 are versatile materials that find applications in a wide range of industries. They are commonly used as binders, coatings, and molding compounds in the production of 390120 Polymers of ethylene, in primary forms, 390190 Polymers of propylene or of other olefins, in primary forms, n.e.c. in heading no. 3901, and 390950 Amino-resins, in primary forms.
