2912.12.00.00 - Ethanal (Acetaldehyde)

This HTS classification covers Ethanal, also known as Acetaldehyde. Ethanal is a simple acyclic aldehyde characterized by its formula CH3CHO. It is a colorless liquid with a pungent, fruity odor, highly volatile and flammable. Its primary function in this classification is as an organic chemical compound, specifically an aldehyde lacking any other oxygen-containing functional groups, and not being a cyclic polymer or paraformaldehyde.

Ethanal is distinguished from its sibling category, Methanal (Formaldehyde), primarily by its chemical structure. Methanal (2912.11.00.00) has one carbon atom in its aldehyde group, whereas Ethanal has two. This structural difference impacts their physical properties, reactivity, and common industrial applications. While both are fundamental aldehydes, their specific uses in the chemical industry, such as in the production of plastics, resins, or solvents, will differ.

As this is a leaf node within the HTS structure for acyclic aldehydes without other oxygen function, there are no further subcategories under 2912.12.00.00. Therefore, classification directly under this code will be for Ethanal itself. Importers and exporters should confirm the identity of the substance as Ethanal based on its chemical name, CAS number, and physical characteristics to ensure correct classification.
