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

HS v2017 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 organic compounds are essential building blocks in the production of various petrochemicals, plastics, and synthetic rubbers. As key intermediates in the chemical industry, they play a crucial role in the manufacturing of a wide range of consumer and industrial products, making this code an important part of the broader economy.

Production process

Buta-1,3-diene and isoprene are typically produced through the steam cracking of naphtha or natural gas liquids. This process involves heating the feedstock to high temperatures, causing the hydrocarbon molecules to break down into smaller unsaturated compounds. The desired products are then separated and purified through a series of distillation and separation techniques.

Production inputs

The main inputs for the production of buta-1,3-diene and isoprene under HS code 290124 include naphtha, natural gas liquids, and other hydrocarbon feedstocks. Specialized equipment such as steam crackers, distillation columns, and separation units are also essential for the manufacturing process. Additionally, energy sources, such as natural gas or electricity, are required to power the production facilities.

Production outputs

The primary outputs of HS code 290124 are buta-1,3-diene and isoprene, which are then consumed by various downstream industries. Buta-1,3-diene is a key raw material for the production of 400210 (Styrene-butadiene rubber (SBR)) and 400220 (Butadiene rubber (BR)), while isoprene is used in the manufacture of 400111 Natural rubber and gums, in primary forms or in plates, sheets or strip. These outputs are further processed and incorporated into a wide range of products, including tires, automotive parts, and consumer goods.
