Cyclic hydrocarbons; mixed xylene isomers

HS v2022 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 as solvents and as feedstocks for the production of various chemicals and materials. The xylene industry plays a crucial role in the broader petrochemical sector, supporting a range of downstream industries such as plastics, paints, and coatings.

Production process

The production of mixed xylene isomers typically involves the separation and purification of xylene 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 such as distillation columns, adsorption units, and crystallization tanks. Additionally, the industry relies on a range of supporting infrastructure, including pipelines, storage facilities, and transportation networks to move the 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 390210 Polystyrene, and the formulation of 320910 Paints and varnishes. The xylene industry also generates other valuable byproducts, such as toluene and benzene, which are classified under separate HS codes.
