Overview
This HTS category, 9902.02.96, specifically covers Himic anhydride, also known by its IUPAC name 1,2,3,6-tetrahydro-3,6-methanophthalic anhydride. This chemical compound, identified by CAS Number 826-62-0, is a particular anhydride used in various chemical synthesis processes. Its inclusion within Chapter 99 signifies its treatment under temporary legislation or specific trade agreement provisions, diverging from its standard classification under Chapter 29.
Distinguishing this category from its siblings within Section XXII is crucial. While Section XXII generally pertains to temporary legislation, trade agreements, and agricultural import restrictions, the specific codes within Chapter 99, such as 9902.02.96, address particular commodities under these special provisions. Unlike general tariffs that might apply to broader chemical categories, this code is reserved for Himic anhydride when subject to these unique regulatory circumstances.
As a leaf node in the HTS database, HTS 9902.02.96 has no further subcategories. Classification under this code is definitive for Himic anhydride when imported under the conditions outlined in its accompanying temporary legislation. Importers must ensure that the specific import scenario aligns with the provisions triggering this classification, as its primary chemical classification is provided for under subheading 2917.20.00, and this chapter 99 code represents an exceptional treatment.
