HS v2022 Code: 291822

About acids; carboxylic acids, (with phenol function but without other oxygen function), o-acetylsalicylic acid, its salts and esters

HS code 291822 covers a group of carboxylic acids with a phenol functional group, including the well-known compound o-acetylsalicylic acid, commonly known as aspirin. These acids and their derivatives are widely used in the pharmaceutical, chemical, and personal care industries, playing a crucial role in the production of various medications, personal care products, and other important goods. As a key component of the broader organic chemicals industry, this code represents a significant segment of international trade and economic activity.

Production process

The production of the compounds covered under HS code 291822 typically involves chemical synthesis processes. The starting materials, such as salicylic acid or phenol, undergo a series of reactions, including acetylation, esterification, and salt formation, to create the desired carboxylic acids and their derivatives. These processes are carried out in controlled laboratory or industrial settings, often using specialized equipment and carefully monitored reaction conditions to ensure product quality and consistency.

Production inputs

The main inputs required for the production of the compounds under HS code 291822 include raw materials such as salicylic acid, phenol, acetic anhydride, and various alcohols and bases used in the synthesis and purification processes. Additionally, the industry relies on specialized equipment, including reactors, distillation columns, and purification systems, as well as a skilled workforce with expertise in organic chemistry and chemical engineering.

Production outputs

The primary outputs of the industry covered by HS code 291822 are the carboxylic acids and their derivatives, such as o-acetylsalicylic acid (aspirin), salts of these acids, and various esters. These compounds find widespread use in the pharmaceutical industry for the production of pain relievers, anti-inflammatory drugs, and other medicinal products. They are also used in the personal care industry for the formulation of cosmetics, skincare products, and other consumer goods. The outputs of this industry may be further processed or incorporated into the production of 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, 330499 Preparations for use on the hair, n.e.c. in heading no. 3304, and other related HS codes.
