2925.19.70.00 - N-Chlorosuccinimide; andN,N'-Ethylene bis (5,6-dibromo-2,3- norbornane dicarboximide)

This HTS category, 2925.19.70.00, specifically enumerates and classifies two distinct imide compounds: N-Chlorosuccinimide and N,N'-Ethylene bis(5,6-dibromo-2,3-norbornane dicarboximide). N-Chlorosuccinimide is a halogenated derivative of succinimide, often employed as a selective oxidizing agent and chlorinating agent in organic synthesis, particularly in the pharmaceutical and agrochemical industries. The second compound is a more complex, polycyclic imide containing bromine substituents, likely used in specialized applications such as flame retardants or advanced material synthesis due to its unique structural features.

This classification distinguishes itself from its sibling category, 2925.19.91.00 "Other," by its specific and explicit naming of the included chemical substances. While the "Other" category would encompass any imide or imine derivatives not otherwise specified, this particular heading is reserved solely for the two named compounds. Therefore, any imide derivative that does not precisely match the chemical identity of N-Chlorosuccinimide or N,N'-Ethylene bis(5,6-dibromo-2,3-norbornane dicarboximide) would fall under the broader "Other" category at this level.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific code. Classification decisions under this heading rely entirely on the accurate identification and verification of the chemical composition of the imported or exported goods. Importers and exporters must ensure that their product precisely corresponds to the chemical structures and nomenclature of N-Chlorosuccinimide or N,N'-Ethylene bis(5,6-dibromo-2,3-norbornane dicarboximide) to correctly utilize this classification.
