About HS Code 290123
This category covers butene and its various isomers, such as 1-butene, 2-butene (cis and trans), and isobutylene. These unsaturated acyclic hydrocarbons are vital intermediates in the production of a wide range of chemicals and polymers. They are primarily used as co-monomers in polyethylene production, for manufacturing synthetic rubber (e.g., butyl rubber), and in the synthesis of fuel additives and specialty chemicals. International trade involves chemical companies and refiners, with major exporters often being countries with large petrochemical complexes or advanced refining capabilities, such as the United States, Saudi Arabia, and the Netherlands. Key importers include industrial nations like China, Germany, and Japan, which have significant downstream manufacturing industries. Transport typically involves specialized tankers or rail cars for liquefied gases. Market prices are influenced by crude oil and natural gas prices, as well as demand from the automotive and plastics sectors.
Products Under This Code
1-Butene, Isobutylene, Cis-2-Butene, Trans-2-Butene, Butene-1, Isobutene, Mixed Butenes
Real World Examples
ExxonMobil Chemical (producer of isobutylene), LyondellBasell (producer of 1-butene), SABIC (producer), INEOS (producer), BASF (producer)
Common Misclassification
Can be confused with other C4 hydrocarbons like 290124 (butadiene) or even 290110 (butane) if the unsaturation is overlooked. The presence of a double bond and the specific C4 structure are key.
Products Classified Under 2901.23
