HS Code 2922.41 – Amino-acids, other than those containing more than one kind of oxygen function, and their esters; lysine and its esters; salts thereof
HS code 2922.41 is the 6-digit subheading for amino-acids, other than those containing more than one kind of oxygen function, and their esters, lysine and its esters, salts thereof. It is used for L-Lysine Monohydrochloride, L-Lysine Sulfate, L-Lysine Base, lysine Ethyl Ester Dihydrochloride and lysine Methyl Ester Dihydrochloride.
What HS 2922.41 covers
This HS code specifically covers lysine, a vital essential amino acid, and its various esters and salts, provided they do not contain more than one type of oxygen function. Lysine is indispensable in human and animal nutrition, playing a critical role in protein synthesis, calcium absorption, and hormone production. In international trade, lysine is primarily imported by the animal feed industry as a crucial supplement to enhance the nutritional value of livestock feed, particularly for poultry and swine. It is also used in the food industry as a dietary supplement and in pharmaceuticals. Exporters are typically large-scale biochemical manufacturers, often located in regions with significant fermentation capabilities. Key aspects of trade include ensuring high purity levels, compliance with food and feed safety regulations, and managing global supply chain logistics for a bulk commodity. The market is highly competitive, with demand driven by global meat consumption and animal husbandry practices, making it a cornerstone of modern agriculture.

Codes often confused with 2922.41
Common mistake. This code is distinct from other amino acids in 292249, which covers "other" amino acids. Confusion can arise if a lysine derivative contains multiple oxygen functions, potentially leading to classification under 292250 or other organic chemical codes.
Top exporters and importers of HS code 292241, 2025
In 2025, the largest exporter of HS code 292241 in UN Comtrade data was China, with 59% of world exports; the largest importer in UN Comtrade data was the Netherlands, with 6.6% 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).
