2913.00.40.00 - Other

This HTS classification, 2913.00.40.00, encompasses "Other" halogenated, sulfonated, nitrated, or nitrosated derivatives of aromatic aldehydes or ketones originating from heading 2912, which are not specifically enumerated elsewhere within the 2913.00 subheading. These products are characterized by the presence of at least one halogen (fluorine, chlorine, bromine, or iodine), a sulfonyl group (-SO2R), a nitro group (-NO2), or a nitroso group (-NO) attached to an aromatic ring system that is also substituted with an aldehyde or ketone functional group.

It is crucial to distinguish this category from its sibling, 2913.00.20.00, which specifically classifies 4-Fluoro-3-phenoxybenzaldehyde. This distinction is based on the precise chemical structure and substitution pattern of the molecule. While both are halogenated aromatic aldehydes, the "Other" category is for any such compounds not matching the specific structure of 4-Fluoro-3-phenoxybenzaldehyde, allowing for a broader range of halogenated, sulfonated, nitrated, or nitrosated aromatic aldehydes and ketones.

As this is a leaf node in the HTS classification structure, there are no further subcategories to introduce. Therefore, classification within 2913.00.40.00 relies on a thorough analysis of the chemical composition and structure of the imported or exported good. Importers and exporters must confirm that the product meets the criteria of being a halogenated, sulfonated, nitrated, or nitrosated derivative of an aromatic aldehyde or ketone from heading 2912, and crucially, that it is not specifically provided for under any preceding subheading within 2913.00.
