HS v2017 Code: 291821

About acids; carboxylic acids, (with phenol function but without other oxygen function), salicylic acid and its salts

HS code 291821 covers a group of carboxylic acids with a phenol function, including the important compound salicylic acid. These acids are widely used in the production of various pharmaceutical, personal care, and industrial products. They play a crucial role in the chemical industry and have applications across diverse sectors, contributing to the broader economy.

Production process

The primary production technique for the compounds covered under HS code 291821 is chemical synthesis. This typically involves the reaction of phenol with various carboxylic acid precursors, often in the presence of catalysts and under controlled temperature and pressure conditions. The specific steps may vary depending on the target compound, but the general approach is to facilitate the formation of the desired carboxylic acid structure with the phenol functional group.

Production inputs

The main inputs required for the production of the compounds under HS code 291821 include phenol, various carboxylic acid precursors, catalysts, and energy sources (such as heat or electricity) to power the chemical synthesis processes. Additionally, specialized equipment like reactors, distillation columns, and purification systems are necessary to ensure the efficient and high-quality production of these carboxylic acids.

Production outputs

The primary outputs of the industry covered by HS code 291821 are the carboxylic acids with a phenol function, including salicylic acid and its salts. These compounds find widespread use in the production of 300410 Medicaments; containing antibiotics, not put up for retail sale, 330499 Cosmetic and toilet preparations; not elsewhere specified or included, and 380899 (Pesticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, put up in forms or packings for retail sale or as preparations or articles (e.g. sulphur-treated bands, wicks and candles, and fly-papers)), among other industries.
