Overview
This HTS category, 9902.03.78, specifically classifies "(1S)-1-Phenylethanamine (CAS No. 618-36-0)". This is a specific chiral amine, commonly used as a chiral resolving agent or a building block in the synthesis of pharmaceuticals and other fine chemicals. Its inclusion under Chapter 99 indicates that it is subject to temporary legislation or specific import restrictions, often tied to trade agreements or agricultural policies.
Unlike the numerous primary headings found in earlier chapters of the HTS (such as Chapter 01 for live animals), this category is situated within a specialized chapter designed for temporary measures. Its sibling categories, if present within Chapter 99, would also pertain to temporary or exceptional trade provisions rather than broad commodity groups. Therefore, the primary distinguishing factor is its placement within this chapter, signifying a specific trade policy or restriction rather than a general classification of goods.
As a leaf node within the HTS structure, 9902.03.78 does not have further subcategories. Classification at this level relies on the precise chemical identity of the substance, as indicated by its name and CAS number. Importers must ensure that the imported material precisely matches the chemical description and that all associated temporary legislation or restrictions under this heading are fully complied with, including any required documentation or permits.
