HS v2022 Code: 290491

About derivatives of hydrocarbons; trichloronitromethane (chloropicrin), whether or not halogenated

HS code 290491 covers a range of chemical compounds derived from hydrocarbons, including the important substance trichloronitromethane, also known as chloropicrin. These derivatives have a wide variety of industrial and commercial applications, making them an integral part of the global chemical industry. Their production and trade play a significant role in supporting various downstream sectors, contributing to the overall economic activity.

Production process

The production of the chemicals classified under HS code 290491 typically involves a series of chemical reactions and purification processes. The starting point is often the extraction or synthesis of specific hydrocarbon compounds, which are then subjected to various halogenation, nitration, or other chemical modifications to create the desired derivatives. Advanced techniques such as distillation, crystallization, and column chromatography are commonly employed to ensure the purity and quality of the final products.

Production inputs

The main inputs required for the production of HS code 290491 chemicals include a range of hydrocarbon feedstocks, such as 271011 Petroleum oils and oils obtained from bituminous minerals, other than crude, 290110 Saturated acyclic hydrocarbons, and 290230 Toluene. Additionally, various chemical reagents, catalysts, and specialized equipment, such as reactors, distillation columns, and purification systems, are essential for the manufacturing process.

Production outputs

The chemicals classified under HS code 290491 are widely used as intermediates in the production of other chemical compounds, pharmaceuticals, and agricultural products. Some of the key outputs include chloropicrin, which is used as a soil fumigant and a chemical warfare agent, as well as other halogenated and nitrated hydrocarbon derivatives that find applications in the 380810 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, 380830 Herbicides, anti-sprouting products and plant-growth regulators, and 300490 Medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale, n.e.c. in heading 30.04.
