Paraformaldehyde Methanol Stabilized 94%
This 94% paraformaldehyde powder stabilized with 4-6% methanol prevents premature depolymerization during storage and transport for pharmaceutical intermediate synthesis. HTS 2912.60.00.00 classification applies per Chapter 29 note 1(f) allowing stabilizers necessary for preservation. The methanol addition qualifies as safety/transport stabilizer without changing primary aldehyde function.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If methanol content exceeds 15% of total weight
High solvent content converts product to chemical preparation of Chapter 38 rather than stabilized pure compound.
If when imported primarily as methanol with paraformaldehyde dissolved
Principal function determines classification; solvent-dominant mixtures follow alcohol headings.
If stabilizer creates saturated acyclic alcohol function predominance
Chapter note prioritizes oxygen function occurring last in numerical order.

Import Tips & Compliance
• Document methanol stabilizer percentage (<10%) per Chapter 29 note 1(f) to maintain paraformaldehyde classification
• Dual hazard declaration required for formaldehyde and methanol vapors per IMDG Code
• Include stabilizer compatibility test results preventing classification as chemical mixture
