2922.49.49 - Other amino acids

This category, HTS Code 2922.49.49, encompasses a broad range of amino acids that do not fall into more specific classifications within heading 2922. It includes amino acids that possess a single amino group and a single carboxyl group, with or without additional oxygen-containing functional groups but not more than one *kind* of oxygen function beyond the carboxyl group. These are distinct from amino acids with multiple types of oxygen functions, which are classified elsewhere.

Distinguishing this category from its sibling, 2922.49.43.00 (Glycine), is crucial. While glycine is a fundamental and commonly traded amino acid, this current category covers all *other* amino acids that meet the general criteria of heading 2922. This means it includes a vast array of naturally occurring and synthetic amino acids beyond glycine, such as alanine, aspartic acid, glutamic acid, lysine, and methionine, among many others.

The subcategories under 2922.49.49.00 provide further refinement for specific, high-volume amino acids. For instance, 2922.49.49.10 covers Alanine, and 2922.49.49.15 covers l-Aspartic acid. These subdivisions are established to facilitate more precise classification and trade management for commonly recognized and commercially significant amino acids. The residual subcategory, 2922.49.49.50, serves as a catch-all for any other amino acids that fit the general description but are not individually enumerated in the preceding subcategories.
