Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-reacted into urea-formaldehyde resin rather than used as formaldehyde source
Completed synthetic resins containing paraformaldehyde derivatives are classified in Chapter 39 by plastic type, not chemical intermediate status.
If for other unspecified aldehydes when paraformaldehyde purity falls below 91%
Chapter 29 prioritizes specific chemical identity; impure or mixed aldehyde polymers may fall under residual aldehyde provisions.
If when supplied as aqueous solution with >10% water content
Chemical preparations in solution exceeding paraformaldehyde concentration limits are classified as mixtures in Chapter 38.

Import Tips & Compliance
• Provide manufacturer's specification sheet confirming prill size (typically 1-3mm) and formaldehyde polymer structure
• Declare exact water content as higher moisture levels may trigger reclassification from pure paraformaldehyde
• Use UN3375 or UN2210 packaging compliant with formaldehyde emission regulations and IATA dangerous goods standards
