Nitrogen-function compounds; n.e.c. in chapter 29, isocyanates

HS code 292910 covers a range of nitrogen-containing organic compounds, including isocyanates. These compounds play a vital role in the production of various industrial and consumer goods, such as polyurethane foams, coatings, adhesives, and sealants. The isocyanates industry is a crucial component of the broader chemical industry, contributing to the manufacturing of a wide array of products that are essential for numerous sectors, including construction, automotive, and consumer goods.

The production of isocyanates typically involves the reaction of primary amines with phosgene (carbonyl chloride) under controlled conditions. This process results in the formation of the desired isocyanate compound, which is then purified and prepared for further processing or use in downstream applications.

The main inputs required for the production of isococyanates include primary amines, such as aniline or toluene diamine, as well as phosgene. Additionally, specialized equipment, such as reactors, distillation columns, and purification systems, are necessary to ensure the efficient and safe production of these compounds. Energy sources, such as electricity or steam, are also essential for the various stages of the manufacturing process.

The primary outputs of the isocyanates industry are the various types of isocyanate compounds, which are then used as key ingredients in the production of a wide range of products. These include 392100 Polyurethanes, 320910 Paints and varnishes, 391000 Plastics, and 401120 Pneumatic tires, among others. The specific isocyanate compounds produced under HS code 292910 may be further classified under other HS codes, such as 292910 Toluene diisocyanate or 292910 Methylene diphenyl diisocyanate.
