2925.19.91.00 - Other

This HTS category, 2925.19.91.00, is designated for "Other" imide and imine-function compounds and their salts that do not fall under more specific subheadings within the 2925.19 range. It acts as a residual category for a diverse array of carboxyimide- and imine-function compounds that are not otherwise enumerated. The classification within this subheading typically relies on the absence of specific structural or functional characteristics that would place the product in a more precisely defined category.

Distinguishing this "Other" category from its sibling, 2925.19.70.00, is crucial. The sibling category explicitly enumerates N-Chlorosuccinimide and N,N'-Ethylene bis (5,6-dibromo-2,3-norbornane dicarboximide). Therefore, any imide or imine-function compound or their salt that does not possess the precise chemical structures of these two named substances will likely fall into the residual 2925.19.91.00 category, provided it meets the broader definition of the parent headings.

As this is a leaf node, there are no further subcategories to introduce. Classification into this subheading is therefore determined by exclusion of all other more specific subheadings within the 2925.19 group, and confirmation that the product is indeed an imide or imine-function compound or their salt. When classifying goods under this heading, it is essential to consult specific chemical nomenclature and ensure that the product's characteristics do not align with any preceding, more detailed descriptions within the HTS.
