Overview

This category, HTS Code 2931, encompasses a broad range of chemical compounds that are characterized by the presence of both organic and inorganic elements bonded together. These are referred to as "other organo-inorganic compounds" and represent a diverse group of substances not specifically classified in other more defined organo-inorganic categories within Chapter 29. The key distinguishing feature is the direct linkage between a carbon atom (organic) and a non-metallic element or a metal (inorganic).

Unlike the preceding categories in Chapter 29, which focus on specific types of organic chemicals like aldehydes, ketones, or alcohols, HTS 2931 captures compounds that do not fit those more specialized classifications. Its role is to serve as a residual category for organo-inorganic compounds. This means that if a compound contains both organic and inorganic components but doesn't meet the criteria for, for example, organo-sulfur compounds (heading 2930) or organo-halogen compounds (heading 2931.80, if explicitly listed), it will likely fall under heading 2931.

Within HTS 2931, further subdivisions exist to provide more granular classification for commonly encountered types of organo-inorganic compounds. These subcategories may include specific examples like tetramethyl lead and tetraethyl lead (2931.10.00.00) and tributyltin compounds (2931.20.00.00), which are recognized for their distinct chemical structures and applications. Other subdivisions, such as non-halogenated organo-phosphorous derivatives and halogenated organo-phosphorous derivatives, highlight the importance of the inorganic component in determining classification. The "Other" category (2931.90) acts as a final catch-all for any remaining organo-inorganic compounds that do not fit into these more specific subheadings, ensuring comprehensive coverage.
