About acyclic hydrocarbons; unsaturated, n.e.c. in heading no. 2901

HS code 290129 covers a diverse range of unsaturated acyclic hydrocarbons that are not classified elsewhere under heading 2901. These compounds play a crucial role in the chemical industry, serving as essential building blocks for the production of a wide array of products, from fuels and solvents to plastics and pharmaceuticals. Their versatility and importance in the global economy make them a significant focus of international trade and regulatory oversight.

Production process

The production of the unsaturated acyclic hydrocarbons classified under HS code 290129 typically involves various petrochemical processes, such as catalytic cracking, dehydrogenation, and oligomerization. These techniques aim to selectively convert saturated hydrocarbons, often derived from natural gas or crude oil, into the desired unsaturated compounds through the manipulation of temperature, pressure, and the use of specialized catalysts.

Production inputs

The primary inputs for the production of HS code 290129 compounds include various hydrocarbon feedstocks, such as 270111 Natural gas, liquefied and 270900 Petroleum oils and oils obtained from bituminous minerals, crude. Additionally, the industry relies on specialized equipment, including reactors, distillation columns, and catalysts, as well as a skilled workforce to operate and maintain the production facilities.

Production outputs

The unsaturated acyclic hydrocarbons classified under HS code 290129 are widely used as intermediates in the production of a diverse range of downstream products. These compounds may be further processed and incorporated into the manufacturing of 290230 Benzene, 290240 Xylenes, and other aromatic hydrocarbons, which are then utilized in the production of fuels, solvents, plastics, and a variety of other industrial and consumer goods.
