Acids; carboxylic acids, (with alcohol function but without other oxygen function), tartaric acid

HS v2022 Code: 291812

About acids; carboxylic acids, (with alcohol function but without other oxygen function), tartaric acid

HS code 291812 covers the classification of tartaric acid, a versatile carboxylic acid with an alcohol function. Tartaric acid is a key ingredient in various industries, from food and beverage production to pharmaceutical and chemical manufacturing. Its importance extends across a wide range of applications, making it a vital component in the global economy.

Production process

Tartaric acid is primarily produced through the fermentation of grape juice or wine. The process involves the natural precipitation of tartaric acid crystals, which are then harvested, purified, and refined to meet the desired purity and quality standards. Advanced techniques, such as ion exchange and crystallization, may also be employed to further refine the final product.

Production inputs

The main inputs required for the production of tartaric acid include grape juice or wine, as well as various processing chemicals and equipment. Specialized fermentation tanks, filtration systems, and crystallization equipment are essential for the efficient and high-quality production of tartaric acid.

Production outputs

The primary output of HS code 291812 is refined tartaric acid, which is widely used in the food and beverage industry as a pH regulator, flavor enhancer, and preservative. Tartaric acid is also a key ingredient in the production of 291815 Salts and esters of tartaric acid, 291816 Salts and esters of citric acid, and various pharmaceutical and chemical products.
