HS Code 2922.49 – Amino-acids, other than those containing more than one kind of oxygen function, their esters; salts thereof, excluding lysine, glutamic acid, anthranalic acid and tilidine, their esters and salts thereof
HS code 2922.49 is the 6-digit subheading for amino-acids, other than those containing more than one kind of oxygen function, their esters, salts thereof, excluding lysine, glutamic acid, anthranalic acid and tilidine, their esters and salts thereof. It is used for glycine, L-Alanine, L-Valine, L-Leucine and L-Isoleucine.
What HS 2922.49 covers
This broad residual HS code covers "other" amino acids, their esters, and salts, provided they do not contain more than one type of oxygen function, and explicitly excludes lysine, glutamic acid, anthranilic acid, and tilidine, which have their own specific subheadings. This category includes a vast array of amino acids, both proteinogenic and non-proteinogenic, that serve diverse functions across various industries. In international trade, these compounds are imported by pharmaceutical companies for drug synthesis, by the food and beverage industry for nutritional supplements and flavorings, by cosmetic manufacturers, and by research institutions. Exporters are typically specialty chemical manufacturers and biochemical companies worldwide. Key considerations for trade include the high purity requirements for pharmaceutical and food-grade applications, specific enantiomeric forms (L- or D-), and compliance with various industry-specific regulations. The market is highly fragmented, driven by specialized applications and ongoing research in biotechnology and medicine, making it a dynamic sector.

Codes often confused with 2922.49
Common mistake. This code is a "basket" category for amino acids not specifically listed elsewhere in 2922.41 through 2922.44. Misclassification often occurs if one of the specifically enumerated amino acids (lysine, glutamic acid, anthranilic acid, tilidine) is incorrectly placed here, or if an amino acid derivative contains multiple oxygen functions, leading to 292250.
Top exporters and importers of HS code 292249, 2025
In 2025, the largest exporter of HS code 292249 in UN Comtrade data was China, with 39% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
