HS v2017 Code: 2912

About aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde

HS code 2912 covers a diverse range of organic compounds known as aldehydes. Aldehydes are an important class of chemicals with a wide range of industrial and commercial applications. They are used in the production of various pharmaceuticals, plastics, resins, and fragrances, making them a crucial component in many sectors of the global economy. This code encompasses both simple and complex aldehyde compounds, as well as their cyclic polymers and paraformaldehyde, a key industrial chemical.

Production process

Aldehydes are typically produced through the oxidation of alcohols or the hydroformylation of alkenes. The specific production techniques can vary depending on the target aldehyde compound, but generally involve the use of catalysts, high temperatures, and controlled reaction conditions. Cyclic polymers of aldehydes, such as trioxane, are often synthesized through the condensation of formaldehyde, while paraformaldehyde is produced by the depolymerization of formaldehyde.

Production inputs

The main inputs required for the production of aldehydes and related compounds under HS code 2912 include alcohols, alkenes, and formaldehyde as raw materials. Additionally, various catalysts, solvents, and energy sources are necessary for the chemical reactions and purification processes involved. Specialized equipment, such as reactors, distillation columns, and drying units, are also essential for the manufacturing of these products.

Production outputs

The outputs of the industries covered by HS code 2912 include a wide range of aldehyde compounds, such as 2912 Aldehydes, 2912 Cyclic polymers of aldehydes, and 2912 Paraformaldehyde. These outputs are then consumed by various downstream industries, including 2924 Carboxyamide-function compounds; amide-function compounds of carbonic acid, 3907 Polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms, and 3301 Essential oils and resinoids; perfumery, cosmetic or toilet preparations, among others.
