Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing other oxygen functions beyond simple dialdehyde structure
Chapter notes require classification in the numerically later heading; compounds with additional oxygen groups go to 'other' acyclic aldehydes.
If formulated as industrial mixture with additives exceeding Chapter 29 tolerances
Solutions with functional additives rendering them suitable for specific uses fall under prepared chemical mixtures, not pure compounds.
If imported specifically as synthetic tanning agent preparation
End-use preparations of synthetic organic products as tanning agents are excluded from Chapter 29 per chapter note exclusions.

Import Tips & Compliance
• Verify concentration labeling meets Chapter 29 note (e) requirements for aqueous solutions to avoid reclassification as mixtures
• Include Material Safety Data Sheets (MSDS) showing glyoxal purity >95% base content to confirm classification under specific subheading
• Ensure DOT-compliant packaging for hazardous dialdehydes to prevent customs holds due to transport safety violations
