Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If paraformaldehyde (solid polymer)
Cyclic polymers of aldehydes like paraformaldehyde fall under later heading 2912.60 per Chapter 29 classification note.
If contains >50% other substances for specific end-use
Mixtures exceeding simple solutions may classify as chemical preparations under Chapter 38 if not meeting pure compound criteria.

Import Tips & Compliance
• Provide Certificate of Analysis confirming formaldehyde content and purity to verify classification under 2912.11.00.00
• Include stabilizer documentation if present; stabilizers are allowed per Chapter 29 note (f) but must not change essential character
• Ensure proper UN-approved packaging for hazardous goods; formaldehyde solutions are regulated under DOT hazmat rules
