Overview
This HTS category, 9902.04.92, specifically covers Aminoguanidine bicarbonate, identified by CAS Number 2582-30-1. This designation falls under Chapter 99, which is reserved for temporary legislation, modifications related to trade agreements, and specific import restrictions enacted under Section 22 of the Agricultural Adjustment Act. Therefore, goods classified here are subject to special provisions beyond the standard HTS tariff structure.
As a leaf node within Chapter 99, this category does not have further subdivisions. Its placement within this chapter signifies that Aminoguanidine bicarbonate is being managed under specific, often temporary, trade policies or restrictions. While the general description notes its provision under subheading 2928.00.50, this 9900 series code indicates a layer of regulatory control or a specific trade measure applied to this particular chemical compound. This distinguishes it from its "sibling" categories within Chapter 99, which would represent other goods or substances subject to similar, but distinct, temporary measures.
Understanding the classification of Aminoguanidine bicarbonate under 9902.04.92 requires awareness of the underlying trade agreements or Section 22 provisions that led to its inclusion here. This code is not a general tariff classification for the chemical itself but rather an indicator of specific import requirements or limitations imposed by U.S. trade legislation. Importers must consult the relevant proclamations and legislation associated with Chapter 99 to determine the precise conditions for importation.
