HS v2022 Code: 290551

About alcohols; acyclic; halogenated, sulphonated, nitrated or nitrosated derivatives thereof, ethchlorvynol (inn)

HS code 290551 covers a range of acyclic alcohols that have been chemically modified through halogenation, sulphonation, nitration, or nitrosation. These specialized alcohols have a variety of industrial and pharmaceutical applications, making them an important part of the broader chemicals and pharmaceuticals sector. As a key input for many downstream products, this code plays a crucial role in supporting economic activity across multiple industries.

Production process

The production of the alcohols covered under HS code 290551 typically involves a multi-step chemical synthesis process. This often begins with the extraction or synthesis of the base alcohol compound, which is then subjected to one or more chemical reactions to introduce the desired functional groups. Common techniques include halogenation using halogens or halogenating agents, sulphonation using sulfuric acid or sulfur trioxide, and nitration or nitrosation using nitric acid or nitrite compounds.

Production inputs

The main inputs required for the production of HS code 290551 alcohols include the base alcohol compounds, as well as various chemical reagents and catalysts needed for the modification reactions. Specialized production equipment such as chemical reactors, distillation columns, and purification systems are also essential. Additionally, reliable supplies of energy, water, and other utilities are necessary to facilitate the manufacturing process.

Production outputs

The alcohols classified under HS code 290551 are used as intermediates and building blocks in the production of a wide range of downstream products. These may include 290559 Alcohols, acyclic, and their halogenated, sulphonated, nitrated or nitrosated derivatives, n.e.c., 293723 Hormones, prostaglandins, thromboxanes and leukotrienes, natural or reproduced by synthesis; derivatives and structural analogues thereof, including chain modified polypeptides, used primarily as hormones, and 300490 Medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale, n.e.c., among others.
