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

HS v2017 Code: 291814

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

HS code 291814 covers citric acid, a widely used carboxylic acid with an alcohol function. Citric acid is a crucial ingredient in the food, beverage, and pharmaceutical industries, playing a vital role in the global economy. Its versatile properties, including its ability to act as a preservative, flavoring agent, and pH regulator, make it an indispensable component in a wide range of products.

Production process

Citric acid is primarily produced through the fermentation of sugars, typically using the fungus Aspergillus niger. The process involves the cultivation of the fungus in a nutrient-rich medium, which converts the sugars into citric acid. The resulting solution is then purified and crystallized to obtain the final citric acid product.

Production inputs

The main inputs required for the production of citric acid include carbohydrate sources, such as molasses or glucose, as well as the Aspergillus niger fungus. Additionally, the production process requires various equipment, such as fermentation tanks, centrifuges, and crystallization units. Skilled labor and energy resources, such as electricity or steam, are also essential inputs for the efficient manufacture of citric acid.

Production outputs

The primary output of HS code 291814 is citric acid, which is then consumed by a wide range of industries. Citric acid finds applications in 200919 Fruit juices and vegetable juices, 300490 Medicaments, 330499 Cosmetic and toilet preparations, and 380899 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, among others. The versatility of citric acid ensures a consistent demand for this important chemical compound.
