2912.11.00.00 - Methanal (Formaldehyde)

This HTS category, 2912.11.00.00, specifically covers methanal, commonly known as formaldehyde. Formaldehyde is an organic chemical characterized by its simple acyclic aldehyde structure, containing a single carbon atom bonded to a hydrogen atom and an oxygen atom via a double bond. It is typically encountered in commerce as an aqueous solution (formalin) or as a solid polymer (paraformaldehyde), which readily depolymerizes to release formaldehyde. This substance serves as a fundamental building block in the chemical industry, utilized extensively in the production of resins, plastics, adhesives, disinfectants, and various other chemical intermediates.

Within the broader classification of acyclic aldehydes without other oxygen function, this HTS code is distinguished by its precise identification of methanal. Its sibling category, 2912.12.00.00, covers ethanal (acetaldehyde), which, while also an acyclic aldehyde, possesses two carbon atoms. The "Other" category at this level, 2912.19, is reserved for acyclic aldehydes that do not fall under the specific classifications of methanal or ethanal.

As a leaf node within the HTS structure, 2912.11.00.00 does not have further subcategories. Classification at this level relies on the definitive chemical identity of methanal. Practical classification considerations often involve verifying the concentration of formaldehyde in aqueous solutions or confirming the polymeric form, paraformaldehyde, which is also included under the scope of this heading when intended for depolymerization to release formaldehyde. The purity and specific presentation of methanal will not alter its classification under this code, provided it meets the definition of the chemical compound.
