L-Aspartic Acid USP Grade
Pharmaceutical-grade L-aspartic acid meeting USP standards, a chemically defined amino acid used in drug formulations and nutritional supplements. It falls under HTS 2922.49.49.15 as a pure L-isomer of aspartic acid, an oxygen-function amino-acid other than those with multiple oxygen functions. This non-essential amino acid plays a key role in protein synthesis and metabolic pathways.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as a salt like magnesium L-aspartate
Salts of amino acids are classified under 2922.50, following Chapter 29 note prioritizing salt headings over acids.
If pre-mixed as immunological product or vaccine buffer
Chapter 29 excludes immunological products of heading 3002, shifting classification to finished pharma preps.
If imported as diagnostic reagent solution >5% concentration
Prepared lab reagents not purely Chapter 29 compounds fall under 3822 as composite diagnostic goods.

Import Tips & Compliance
• Provide Certificate of Analysis (COA) confirming L-isomer purity >98% and USP compliance to avoid reclassification
• Declare exact enantiomeric purity as impurities may trigger Chapter 29 note exclusions
• Include end-use documentation for pharma/food to prevent misclassification as industrial chemical
