Nitrile-function compounds; acrylonitrile

HS code 292610 covers the production and trade of nitrile-function compounds, with a particular focus on acrylonitrile. This class of organic chemicals plays a crucial role in the manufacturing of a wide range of industrial and consumer products, making it an essential component of the global chemical industry. Acrylonitrile, in particular, is a versatile building block used in the production of various plastics, fibers, and synthetic rubbers, which are integral to industries such as automotive, construction, and textiles.

The primary production method for nitrile-function compounds, including acrylonitrile, is the catalytic ammoxidation of propylene. This process involves the reaction of propylene, ammonia, and air over a metal oxide catalyst, typically at elevated temperatures and pressures. The resulting acrylonitrile is then purified and further processed as needed for various applications.

The key inputs for the production of nitrile-function compounds under HS code 292610 include propylene, ammonia, and specialized catalysts. Propylene, a byproduct of oil refining or natural gas processing, serves as the primary raw material. Ammonia is used as a reactant, while the metal oxide catalysts, such as those containing bismuth or antimony, facilitate the ammoxidation reaction. Additionally, energy sources, such as electricity or steam, are required to power the production process.

The primary output of HS code 292610 is acrylonitrile, which is then used as a feedstock for the production of a wide range of downstream products. These include 3906 Acrylic polymers, 3907 Polyacetals, other polyethers and epoxide resins, 3908 Polyamides, and 4002 Synthetic rubber and factice derived from oils, among others. Acrylonitrile is an essential building block for the manufacture of plastics, fibers, and synthetic rubbers, which are crucial materials in industries such as automotive, construction, and textiles.
