Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied ready-formulated as finishing agent with catalysts
Textile finishing preparations containing glyoxal as active ingredient but with functional additives classify in Chapter 38.
If paraformaldehyde content exceeds trace levels
Cyclic polymers of aldehydes fall under separate heading 2912.60, distinguished from acyclic glyoxal.
If diluted and perfumed for cosmetic preservation use
Mixtures with odoriferous substances for specific consumer applications excluded per Chapter 29 note (g).

Import Tips & Compliance
• Provide end-use statement confirming textile crosslinking application to distinguish from excluded tanning preparations
• Test for stabilizer content (<1%) to ensure compliance with Chapter 29 note (f) preservation-only additives
• Declare exact glyoxal concentration via HPLC certificate to avoid undervaluation penalties
