About heading 2912
Aldehydes, whether or not with other oxygen function; cyclic polymers of aldehydes; paraformaldehyde
Heading 2912 covers aldehydes, whether or not they carry other oxygen functions, plus cyclic polymers of aldehydes and paraformaldehyde. It splits first by structure: acyclic aldehydes without other oxygen function (2912.11 to 2912.19), cyclic aldehydes without other oxygen function (2912.21 to 2912.29), and aldehydes with other oxygen function such as aldehyde alcohols, ethers and phenols (2912.41 to 2912.49). The last two lines cover cyclic polymers of aldehydes (2912.50) and paraformaldehyde (2912.60).
