2923.20.10.00 - Purified egg phospholipids, pharmaceutical grade meeting requirements of the U.S. Food and Drug Administration, for use in intravenous fat emulsion

This HTS category encompasses purified egg phospholipids that have achieved pharmaceutical grade status and meet the stringent requirements set by the U.S. Food and Drug Administration (FDA). These phospholipids are specifically intended for use in the formulation of intravenous fat emulsions, critical components in parenteral nutrition. The classification hinges on the purification standards and intended pharmaceutical application, distinguishing these high-purity lecithin derivatives from other forms.

The primary distinction of this HTS code lies in its specificity for pharmaceutical-grade egg phospholipids destined for intravenous fat emulsions. Its sibling category, 2923.20.20, covers "Other" lecithins and phosphoaminolipids. This means that any lecithin or phosphoaminolipid not meeting the rigorous pharmaceutical grade and intended use criteria of 2923.20.10.00 would likely fall under the broader "Other" classification, potentially including those for food additives, industrial applications, or less refined grades.

As a leaf node, this classification does not have further subcategories. Therefore, the focus remains on the precise definition of the product. Classification within this code requires verification of the material's origin (egg-derived), its purity and compliance with FDA pharmaceutical standards, and its documented intended use in the manufacturing of intravenous fat emulsions.
