Acyclic hydrocarbons; unsaturated, buta-1,3-diene and isoprene

HS v2022 Code: 290124

About acyclic hydrocarbons; unsaturated, buta-1,3-diene and isoprene

HS code 290124 covers the classification of acyclic unsaturated hydrocarbons, specifically buta-1,3-diene and isoprene. These compounds are essential building blocks in the production of various petrochemicals and synthetic rubber products. As key raw materials for the 400300 Rubber and articles thereof industry, the global demand for buta-1,3-diene and isoprene continues to grow in line with the expanding automotive and manufacturing sectors.

Production process

Buta-1,3-diene and isoprene are typically produced through the steam cracking of naphtha or other light hydrocarbon feedstocks. The process involves heating the feedstock to high temperatures, which causes the hydrocarbon molecules to break down and rearrange into smaller unsaturated compounds. Distillation and purification steps are then used to isolate the desired buta-1,3-diene and isoprene fractions.

Production inputs

The primary inputs for the production of buta-1,3-diene and isoprene under HS code 290124 are light hydrocarbon feedstocks, such as naphtha, liquefied petroleum gas (LPG), or natural gas liquids. Specialized steam cracking furnaces, distillation columns, and other petrochemical processing equipment are also essential for the manufacturing process.

Production outputs

The main outputs of HS code 290124 are buta-1,3-diene and isoprene, which are widely used as monomers in the production of synthetic rubber and other polymeric materials. These compounds are key inputs for the 400300 Rubber and articles thereof industry, as well as the 390100 Polymers of ethylene, in primary forms and 390200 Polymers of propylene or of other olefins, in primary forms industries.
