HS v2017 Code: 290420
About derivatives of hydrocarbons; containing only nitro or only nitroso groups, whether or not halogenated
HS code 290420 covers a range of chemical compounds known as derivatives of hydrocarbons, specifically those containing only nitro or nitroso groups, with or without halogenation. These compounds have diverse applications across various industries, including pharmaceuticals, agrochemicals, and specialty chemicals. Their importance lies in their unique chemical properties and the critical role they play in the production of a wide array of essential products that support the global economy.
Production process
The production of derivatives of hydrocarbons under HS code 290420 typically involves a series of chemical reactions and purification processes. The starting point is often the extraction or synthesis of the base hydrocarbon compound, which is then subjected to nitration or nitrosation reactions to introduce the nitro or nitroso functional groups. Depending on the specific compound, additional steps such as halogenation, distillation, or crystallization may be employed to obtain the desired product characteristics.
Production inputs
The main inputs required for the production of derivatives of hydrocarbons under HS code 290420 include the base hydrocarbon compounds, such as benzene, toluene, or xylene, as well as various chemical reagents and catalysts necessary for the nitration or nitrosation reactions. Additionally, specialized equipment, such as reactors, distillation columns, and purification systems, are essential for the manufacturing process.
Production outputs
The derivatives of hydrocarbons produced under HS code 290420 have a wide range of applications and are consumed by various other industries. These compounds may be used as intermediates in the production of 290410 Derivatives of hydrocarbons; containing only nitro or only nitroso groups, 290490 Derivatives of hydrocarbons, n.e.c. in heading 2904, and 293090 Organo-sulfur compounds, n.e.c. in heading 2930, among others. They are also used in the manufacture of pharmaceuticals, agrochemicals, dyes, and other specialty chemicals.
