Cyclic hydrocarbons; mixed xylene isomers

HS v2017 Code: 290244

About cyclic hydrocarbons; mixed xylene isomers

HS code 290244 covers the classification of cyclic hydrocarbons, specifically mixed xylene isomers. Xylenes are a group of aromatic hydrocarbon compounds that are widely used in the chemical industry as solvents, fuel additives, and as feedstocks for the production of other chemicals. The xylene industry plays a crucial role in the broader petrochemical sector, supporting a range of downstream industries and contributing to the global economy.

Production process

The production of mixed xylene isomers typically involves the separation and purification of xylene compounds from crude oil or natural gas. This is commonly achieved through a combination of distillation, adsorption, and crystallization processes. The specific techniques used may vary depending on the source material and the desired purity of the final product.

Production inputs

The main inputs required for the production of mixed xylene isomers include crude oil or natural gas, as well as various processing equipment and utilities such as energy, water, and catalysts. The industry also relies on a range of supporting infrastructure, including transportation networks and storage facilities, to ensure the efficient movement and handling of raw materials and finished products.

Production outputs

The primary output of HS code 290244 is mixed xylene isomers, which are then consumed by a variety of downstream industries. These include the production of 290243 Xylenes for use as solvents, the manufacture of 290420 Benzene, toluene and xylenes for fuel additives, and the synthesis of 291736 Terephthalic acid and its salts and esters for the production of polyester and other polymers.
