Alcohols; acyclic, diols, other than ethylene glycol (ethandiol) or propylene glycol (propane-1,2-diol)

HS v2017 Code: 290539

About alcohols; acyclic, diols, other than ethylene glycol (ethandiol) or propylene glycol (propane-1,2-diol)

HS code 290539 covers a diverse range of acyclic diols, excluding the commonly known ethylene glycol and propylene glycol. These alcohols play a crucial role in various industries, serving as essential building blocks for the production of a wide array of chemicals, solvents, and specialty products. Their versatility and importance in the global economy make them a significant component of international trade and import/export activities.

Production process

The production of acyclic diols under HS code 290539 typically involves chemical synthesis processes. These may include hydrogenation, oxidation, or other reactions starting from various hydrocarbon feedstocks. The specific techniques employed can vary depending on the target diol and the desired purity levels, often requiring careful control of reaction conditions and purification steps.

Production inputs

The main inputs required for the production of acyclic diols under HS code 290539 include hydrocarbon-based raw materials, such as 290511 Methanol, 290512 (Propan-1-ol (propyl alcohol) and propan-2-ol (isopropyl alcohol)), and other suitable precursors. Additionally, the industry relies on specialized equipment, including reactors, distillation columns, and purification systems, as well as a skilled workforce to operate and maintain the production processes.

Production outputs

The acyclic diols produced under HS code 290539 find applications in a wide range of industries. They are used as intermediates in the synthesis of 290531 (Ethylene glycol (ethanediol)), 290532 (Propylene glycol (propane-1,2-diol)), and other specialty chemicals. These diols are also employed as solvents, plasticizers, and in the production of polyurethanes, polyesters, and other polymeric materials. The outputs from this industry are often consumed by manufacturers in the 3901 Polymers of ethylene, in primary forms, 3907 Polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms, and 3920 Other plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
