Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains impurities exceeding 1% or supplied as technical grade
Purity below analytical standards may classify as 'other' aromatic aldehyde rather than specific p-Hydroxybenzaldehyde.
If primarily considered phenolic compound without aldehyde function emphasized
Chapter notes prioritize aldehyde-oxygen function (2912) over phenol classification (2907), but impure forms may shift.
If dissolved in solvent for transport exceeding safety/handling limits
Chapter note (e) excludes solutions where solvent renders product suitable for specific use beyond general transport.

Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming purity >98% and identity via NMR/IR to verify classification as chemically defined compound
• Ensure SDS includes GHS classification (Acute Tox 4, Eye Irrit 2) and proper UN 3077 packaging for environmental hazard
• Declare exact CAS 123-08-0; misdeclaration as mixture risks reclassification to 2912.49.5000
