2922.41.00 - Lysine and its esters; salts thereof

This HTS category, 2922.41.00, specifically covers lysine, its esters, and their salts. Lysine is an essential amino acid, meaning it cannot be synthesized by the human body and must be obtained through diet or supplements. Consequently, this classification encompasses both the pure amino acid and its derivatives, which are often used in animal feed, pharmaceuticals, and food fortification.

Distinguishing this category from its siblings is crucial. While sibling categories like 2922.42 and 2922.43 address other specific amino acids (glutamic acid and anthranilic acid, respectively) and their salts, 2922.41.00 is exclusively dedicated to lysine and its related compounds. Category 2922.44.00.00 covers a distinct pharmaceutical substance, Tilidine, further delineating the scope of this chapter.

The subcategories within 2922.41.00 differentiate based on the purity and intended application of the lysine products. Subcategory 2922.41.00.10 is reserved for lysine and its derivatives that meet stringent quality standards set by recognized pharmacopeias and food codes, indicating their suitability for direct human consumption or pharmaceutical use. The residual portion, categorized under 2922.41.00.90, would include lysine products not meeting these specific standards, such as those primarily intended for industrial or animal feed applications.
