2929.90.50.95 - Other

This HTS code, 2929.90.50.95, represents a residual category for compounds with other nitrogen functions that do not fit into the more specifically defined subheadings within the "Compounds with other nitrogen function" group. It serves as a catch-all for various organic chemicals containing nitrogen in functional groups not otherwise enumerated. The classification hinges on the absence of the specific structural characteristics described in preceding sibling categories.

To distinguish this category from its siblings, it's crucial to note what is *not* included. For example, it does not cover N,N-Dialkyl phosphoramidic dihalides, dialkyl phosphoramidates, or the specific phosphonamidic fluorides and phosphoramidofluoridates outlined in codes 2929.90.50.20 through 2929.90.50.40. Those subheadings detail precise chemical structures involving phosphorus and specific alkyl or amino substitutions, which are excluded from this general "Other" classification.

As a leaf node, 2929.90.50.95 has no further subcategories. Therefore, the focus for classification into this code is to confirm that a compound contains a nitrogen function and does not meet the criteria for any of the more specific nitrogen-containing organic chemicals listed elsewhere in Chapter 29. This often involves careful examination of the compound's chemical structure to ensure it doesn't possess the defining characteristics of other nitrogen-functional groups, such as amines, amides, nitriles, nitro compounds, or specific organophosphorus nitrogen compounds that have dedicated HTS classifications.
