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

HS v2017 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 widely used carboxylic acid with an alcohol function. Tartaric acid is a crucial ingredient in various industries, including food, beverage, pharmaceutical, and chemical manufacturing. Its versatility and importance in these sectors make it a significant player within the broader chemical industry.

Production process

Tartaric acid is primarily produced through the fermentation of grape juice or wine lees. The process involves the controlled fermentation of grape must, followed by the extraction and purification of the tartaric acid crystals. Advanced techniques, such as ion exchange and crystallization, are often employed to ensure the high purity of the final product.

Production inputs

The main inputs required for the production of tartaric acid include grape juice or wine lees, as well as various processing chemicals and equipment. Grapes are the primary raw material, and the quality and composition of the grape juice or wine lees can significantly impact the yield and purity of the final product. Additionally, the production process requires specialized equipment, such as fermentation tanks, centrifuges, and crystallization units.

Production outputs

Tartaric acid produced under HS code 291812 has a wide range of applications. It is commonly used as a food additive, where it serves as a pH regulator, preservative, and flavor enhancer in various food and beverage products. The pharmaceutical industry also utilizes tartaric acid in the formulation of certain drugs and dietary supplements. Additionally, tartaric acid finds applications in the chemical industry, where it is used as a precursor for the synthesis of other organic compounds. Other HS codes that may consume the output of 291812 include 291811 (Acids; carboxylic acids, (with alcohol function but without other oxygen function), lactic acid) and 291813 (Acids; carboxylic acids, (with alcohol function but without other oxygen function), salts and esters of tartaric acid).
