2928.00 - Organic derivatives of hydrazine or of hydroxylamine:

This HTS category, 2928.00, encompasses organic derivatives of hydrazine and hydroxylamine. These compounds, characterized by the presence of N-N or N-O single bonds within organic molecular structures, find applications in diverse chemical processes. Examples include their use as reagents in organic synthesis, as components in pharmaceuticals, or as precursors in the manufacturing of agricultural chemicals. It is crucial to distinguish these compounds from inorganic hydrazine or hydroxylamine salts, which would be classified elsewhere.

The classification within this chapter, Chapter 29: Organic chemicals, signifies that these are specifically organic compounds. Unlike other chemical classifications that might cover simpler inorganic salts or mixtures not based on organic structures, this heading is precisely for the organic derivatives of hydrazine and hydroxylamine.

The subcategories under 2928.00 further refine the classification based on specific chemical entities. For instance, Methyl ethyl ketoxime and Phenylhydrazine are explicitly listed, allowing for precise identification and duty rate determination for these commonly encountered derivatives. The residual "Other" category serves to capture any other organic derivatives of hydrazine or hydroxylamine not otherwise specified, requiring careful analysis against the chemical structure and functional groups.
