Cyclic hydrocarbons; p-xylene

HS v2022 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 global chemical industry. Its widespread applications in the manufacturing of polyester, solvents, and other industrial products highlight its importance in supporting diverse sectors of the 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 purified to isolate the p-xylene fraction, which is further refined to meet the stringent quality requirements of its end-use applications.

Production inputs

The production of p-xylene relies on the availability of naphtha, a petroleum-derived liquid hydrocarbon stream, as the primary raw material. Additionally, the process requires specialized catalysts, energy sources, and various separation and purification technologies to ensure the efficient and high-quality output of p-xylene.

Production outputs

P-xylene is a versatile chemical that finds application in the manufacture of 540231 polyethylene terephthalate, a widely used plastic material, as well as in the production of solvents and other aromatic compounds. The p-xylene output from this industry is often consumed by 392010 plastic packaging and 540233 polyester staple fibers industries, among others.
