2912.49.26.00 - Other

This HTS category, 2912.49.26.00, encompasses "Other" aromatic aldehydes with an additional oxygen function, excluding those specifically listed as siblings. It broadly covers a diverse range of aromatic aldehyde compounds that possess at least one other oxygen-containing functional group (such as alcohols, ethers, or phenols) in addition to the aldehyde group, and which are not specifically enumerated elsewhere within the 2912.49 subheading. The defining characteristic is the presence of both an aromatic ring and an aldehyde group, coupled with another oxygen functionality, that does not align with the preceding specific entries.

This classification serves as a residual category for aromatic aldehydes with other oxygen functions. It is distinct from the sibling categories of p-Anisaldehyde (2912.49.10.00) and p-Hydroxybenzaldehyde (2912.49.15.00), which are identified by their specific chemical structures and common names. While those specific compounds are precisely defined, this "Other" category accounts for all other aromatic aldehydes meeting the broader criteria of having an additional oxygen function that are not otherwise specified.

As this is a terminal classification node, there are no further subcategories under 2912.49.26.00. Therefore, classification into this category relies on a thorough process of elimination, ensuring the product is indeed an aromatic aldehyde with another oxygen function and does not match any of the more specific classifications within the subheading. Importers and exporters should consult detailed chemical literature and expert advice to accurately determine if their product falls within this "Other" residual category.
