2913.00.50.00 - Other

This category, HTS Code 2913.00.50.00, encompasses "Other" halogenated, sulfonated, nitrated, or nitrosated derivatives of products under heading 2912. Heading 2912 specifically covers aldehydes, whether or not with other oxygen function, and cyclic aldehydes without other oxygen function. Therefore, this subcategory acts as a residual category for compounds that fit the description of being modified by halogenation (substitution with chlorine, bromine, iodine, or fluorine), sulfonation (introduction of a sulfonic acid group), nitration (introduction of a nitro group), or nitrosation (introduction of a nitroso group), but do not fall under more specific classifications within Chapter 29 for such derivatives.

Distinguishing this category from its siblings, "Aromatic" and "VI. KETONE-FUNCTION COMPOUNDS AND QUINONE-FUNCTION COMPOUNDS," is crucial for accurate classification. The "Aromatic" sibling would apply to halogenated, sulfonated, nitrated, or nitrosated derivatives derived from aromatic aldehydes. The "VI. KETONE-FUNCTION COMPOUNDS AND QUINONE-FUNCTION COMPOUNDS" sibling would cover similar derivatives but specifically those possessing ketone or quinone functional groups, which are not the primary characteristic of products under heading 2912. This residual "Other" category is reserved for derivatives of heading 2912 products that do not primarily exhibit aromaticity or possess ketone/quinone functions after the halogenation, sulfonation, nitration, or nitrosation process.

As this is a leaf node, there are no further subcategories. Classification within 2913.00.50.00 relies on confirming that a substance is a halogenated, sulfonated, nitrated, or nitrosated derivative of an aldehyde or cyclic aldehyde covered by heading 2912, and that it does not meet the criteria for any other more specific tariff provision. Practical classification considerations would involve examining the chemical structure and the nature of the substituent groups to ensure they are not of a type that would warrant classification under a distinct heading or subheading.
