2912.19.50.00 - Other

This HTS classification, 2912.19.50.00, encompasses "Other" acyclic aldehydes that do not possess any other oxygen-containing functional groups beyond the aldehyde group. These are aldehydes that are not specifically enumerated in the preceding subheadings within this category. The key defining characteristic is that they are open-chain (acyclic) organic compounds where the primary functional group is an aldehyde (-CHO).

This "Other" category serves as a residual classification for acyclic aldehydes not covered by more specific sibling entries such as Butanal (2912.19.25.00), Glyoxal (2912.19.30.00), or Isobutanal (2912.19.40.00). Classification into this subheading requires a determination that the aldehyde in question is acyclic and lacks any additional oxygen functional groups (like hydroxyl, ether, or carboxylic acid groups) and is not specifically listed elsewhere.

As this is a leaf node, there are no further subdivisions. Therefore, the focus for classifying goods under 2912.19.50.00 is on the precise chemical identity of the acyclic aldehyde and ensuring it does not meet the specific criteria for any other subheading at this level or higher within Chapter 29. Practical classification often involves reviewing the chemical structure and purity of the substance.
