Overview
This HTS subcategory, 2922.49.60.00, specifically covers certain amino acids and their esters that do not contain more than one kind of oxygen function, along with their salts. The primary goods classified here are 3-Aminocrotonic acid, methyl ester, and (R)-α-Amino-1,4-cyclohexadiene-1-acetic acid. These are distinct organic compounds characterized by the presence of both an amino group and a carboxyl group (in ester form), but without additional oxygen-containing functional groups that would place them in other categories.
Distinguishing this category from its sibling, 2922.49.80.00 ("Other"), lies in the specific identification of the chemical compounds. While 2922.49.80.00 would encompass any other amino acids or their esters and salts meeting the broader criteria of 2922.49, this subcategory precisely enumerates the particular substances that fall under its purview. The specificity here ensures that these named compounds are not misclassified with broader "other" provisions when they have a dedicated entry.
As this is a leaf node within the HTS structure, there are no further subcategories for this classification. Therefore, the focus remains on the precise identification and classification of the enumerated substances: 3-Aminocrotonic acid, methyl ester, and (R)-α-Amino-1,4-cyclohexadiene-1-acetic acid. Importers and exporters should ensure these specific chemical names or their recognized CAS numbers are used for accurate declaration to customs authorities.
