9902.04.63 - Creatine (N-carbamimidoyl-N-methylglycine) (CAS No. 57-00-1) (provided for in subheading 2925.29.90)

This HTS category, 9902.04.63, specifically covers Creatine (N-carbamimidoyl-N-methylglycine), identified by CAS No. 57-00-1. While Creatine is a chemical compound, its classification under Chapter 99 indicates it is subject to temporary legislation, modifications pursuant to trade agreements, or additional import restrictions proclaimed under Section 22 of the Agricultural Adjustment Act. This temporary designation means its tariff treatment may differ from its permanent classification under other chapters.

Unlike the broad categories of live animals found in the sibling HTS codes (e.g., 0101 for horses, 0102 for bovine animals), this entry is highly specific to a particular chemical substance. Its placement in Chapter 99 signifies a focus on regulatory controls or temporary trade policies rather than a general commodity grouping. The parenthetical reference "(provided for in subheading 2925.29.90)" further clarifies that the underlying nature of Creatine is that of an organic compound, but the Chapter 99 code supersedes or modifies its standard treatment for import purposes.

As this is a leaf node, there are no further subcategories within 9902.04.63. All goods falling under this specific code will share the same classification and the associated temporary legislative or regulatory provisions. Importers should consult the specific regulations or proclamations referenced by this Chapter 99 code to understand the exact requirements and potential duty implications for importing Creatine.
