Cyclic hydrocarbons; p-xylene

HS v2017 Code: 290243

About cyclic hydrocarbons; p-xylene

HS code 290243 covers the classification of p-xylene, a critical cyclic hydrocarbon compound. P-xylene is an essential raw material in the production of various petrochemicals and plastics, making it a vital component of the broader chemical industry. Its widespread use in the manufacturing of polyethylene terephthalate (PET) for packaging, textiles, and other applications underscores its importance in the global economy.

Production process

P-xylene is primarily produced through the catalytic reforming of naphtha, a process that involves the rearrangement of hydrocarbon molecules to increase the concentration of aromatic compounds. The resulting mixture is then distilled and further purified to isolate the p-xylene fraction, ensuring a high-purity product suitable for downstream applications.

Production inputs

The production of p-xylene requires several key inputs, including naphtha, a hydrocarbon feedstock derived from crude oil refining, as well as specialized catalysts and distillation equipment. Additionally, the process may involve the use of energy sources, such as natural gas or electricity, to power the various stages of production.

Production outputs

The primary output of HS code 290243 is p-xylene, which is then consumed by other industries, such as the 390120 polyethylene terephthalate (PET industry, the 540233 polyester filament yarn industry, and the 392021 plastic plates, sheets, film, foil and strip industry, among others. P-xylene is a crucial building block for the manufacture of a wide range of products, from packaging materials to textiles and engineering plastics.
