p-Tolualdehyde (4-Methylbenzaldehyde)
p-Tolualdehyde, also known as 4-methylbenzaldehyde (C8H8O), is an aromatic aldehyde with a methyl group para to the aldehyde on the benzene ring. It is explicitly named in HTS 2912.29.30.00 for cyclic aldehydes without other oxygen functions, commonly used in flavor, fragrance, and pharmaceutical synthesis. Meets Chapter 29 requirements as a separate chemically defined compound.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for other unspecified cyclic aldehydes
Unnamed cyclic aldehydes without oxygen functions classify under the residual 2912.29.25 provision.
If primarily used as synthetic flavoring aldehyde
Chapter exclusion (g) directs odoriferous substances to Chapter 32 if for specific end use beyond general chemical.
If classified by parent hydrocarbon structure
Benzene derivatives without oxygen function in 2902; aldehyde group mandates oxygen-function classification in 2912.
