Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If analyzed as monomeric acetaldehyde
Only the specific cyclic polymer tetramer qualifies as metaldehyde; monomer acetaldehyde uses different subheading.
If contains heterocyclic ring structures beyond simple cyclic polymer
Chapter notes exclude certain ring structures from cyclic polymer aldehyde classification.
If incorporated into mineral fertilizers
Fertilizer mixtures containing metaldehyde shift to Chapter 31 classifications.

Import Tips & Compliance
• Provide flake size specifications and bulk density data; ensure packaging prevents moisture absorption which destabilizes metaldehyde
• Declare exact tetramer content via NMR or HPLC; impurities must not exceed 2% to maintain classification
• Confirm no added stabilizers beyond transport necessities per Chapter 29 note (f) to avoid reclassification
