Overview
This HTS classification, 9902.03.63, specifically covers Sodium hydrogen 2-aminobenzene-1,4-disulfonate, identified by CAS No. 24605-36-5. This chemical compound, while originating from an amine-based organic compound, falls under a temporary or special classification provision rather than its primary chemical designation. Its presence in Chapter 99 indicates it is subject to specific legislative actions, such as temporary modifications proclaimed pursuant to trade agreements or additional import restrictions under Section 22 of the Agricultural Adjustment Act.
Unlike the general chemical classifications found in Chapters 29 or 30, this entry is not a standard tariff item but a placeholder for a particular product facing unique trade regulations. It is crucial to understand that the underlying chemical substance, Sodium hydrogen 2-aminobenzene-1,4-disulfonate, is also provided for under subheading 2921.42.90, which deals with aniline and its derivatives. However, this 9902 classification indicates that a specific policy or restriction is currently applied to its import.
As this is a leaf node, there are no further subcategories within 9902.03.63. Therefore, classification at this level is definitive and dependent on meeting the specific criteria for this special provision. Importers must verify the current applicability and requirements associated with this 9902 code, as these provisions are often time-sensitive and may be subject to change based on ongoing trade agreements or legislative updates.
