HS Code for Glutamic acid

Glutamic acid is classified under HS code 2922.42. This code is situated within Chapter 29, which covers organic chemicals, and heading 2922, which is reserved for oxygen-function amino-compounds. Glutamic acid is an alpha-amino acid used in the biosynthesis of proteins. The classification 2922.42 specifically includes glutamic acid, its salts, and its esters. The most common salt associated with this code is monosodium glutamate (MSG), provided it is in its pure chemical form. The classification is based on the chemical structure of the molecule, which contains one amino group and two carboxylic acid groups. Under the General Rules of Interpretation, pure chemicals are classified in Chapter 29 even if they have a specific use, such as a food additive. However, the presentation of the product is vital; it must be a separate chemically defined compound. If the glutamic acid or its salts are mixed with other substances to create a prepared seasoning or food enhancer, the classification shifts from the chemical chapter to the food preparation chapter.

Products Included

• Pure L-glutamic acid
• Monosodium glutamate (MSG) in bulk chemical form
• Monopotassium glutamate
• Glutamic acid hydrochloride
• Esters of glutamic acid used in laboratory research

Common Misclassification

The most frequent misclassification occurs with HS code 2103.90, which covers prepared seasonings and mixed condiments. If MSG is packaged for retail sale as a seasoning with other additives, it belongs in 2103. Other amino acids like lysine (2922.41) or methionine (2930.40) are also sometimes confused with glutamic acid due to their similar industrial applications.

FAQ

What is the HS code for pure Monosodium Glutamate?

Pure, chemically defined Monosodium Glutamate is classified under HS code 2922.42.

Is glutamic acid classified differently if used in pharmaceuticals?

No, as long as it is a separate chemically defined compound, it remains under 2922.42 regardless of its intended pharmaceutical or food use.
