Overview
This HTS category, 9902.04.64, specifically covers N-Carbamimidoylglycine, also known as Guanidinoacetic acid (CAS No. 352-97-6). This substance is a chemical compound and its classification within Chapter 99 signifies that it is subject to temporary legislation, modifications under trade agreements, or specific import restrictions under Section 22 of the Agricultural Adjustment Act. While the primary classification for Guanidinoacetic acid would typically fall under subheading 2925.29.90 as a cyclic amide derivative, its presence here in Chapter 99 indicates a special regulatory status imposed by U.S. trade policy.
As a leaf node within the HTS database, this category does not have further subdivisions. Its unique placement within Chapter 99, a section dedicated to temporary measures, distinguishes it from its potential "sibling" categories which might include other chemical compounds or raw materials that are not subject to the same specific temporary trade provisions. The classification is highly specific, focusing on the precise chemical identity and its regulated status rather than broad product groupings.
Therefore, when encountering this HTS code, importers and exporters must pay close attention to the underlying regulations that necessitate its placement in Chapter 99. This could involve specific quotas, duties, documentation requirements, or other restrictions that differ significantly from the standard classification of Guanidinoacetic acid under Chapter 29. Understanding the "provided for in subheading 2925.29.90" note is crucial, as it clarifies the base classification to which these temporary measures are being applied.
