Acids; unsaturated acyclic monocarboxylic acids; methacrylic acid and its salts

HS v2022 Code: 291613

About acids; unsaturated acyclic monocarboxylic acids; methacrylic acid and its salts

HS code 291613 covers a group of unsaturated acyclic monocarboxylic acids, including the important chemical methacrylic acid and its salts. These compounds are widely used in the production of various polymers, plastics, and other industrial materials, making them a crucial part of the global chemical industry. Their versatility and applications span diverse sectors, from construction and automotive to personal care and consumer goods.

Production process

The primary production method for the chemicals under HS code 291613 is catalytic oxidation of isobutylene or other C4 hydrocarbons. This process involves the use of catalysts, typically metal oxides, to facilitate the selective oxidation of the hydrocarbon feedstock into methacrylic acid. The resulting acid is then purified and may be further processed into various salts or derivatives, depending on the desired application.

Production inputs

The main inputs required for the production of the chemicals covered by HS code 291613 include isobutylene or other C4 hydrocarbon feedstocks, as well as various catalysts, solvents, and other processing aids. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the manufacturing process. Additionally, the industry relies on a range of supporting infrastructure, including energy sources, transportation networks, and skilled labor.

Production outputs

The primary outputs of the industry described by HS code 291613 are methacrylic acid and its salts, which are widely used in the production of 390610 Polymers of methyl methacrylate, in primary forms, 390690 Acrylic polymers, in primary forms, n.e.c. in heading no. 3906, and other specialty polymers. These materials find applications in a variety of industries, such as 392010 Plates, sheets, film, foil and strip, of polymers of vinyl chloride, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 391740 (Tubes, pipes and hoses, and fittings therefor (for example, joints, elbows, flanges), of plastics), and 391800 Floor coverings of plastics, whether or not self-adhesive, in rolls or in the form of tiles; wall or ceiling coverings of plastics, as defined in Note 9 to this Chapter.
