Import Tips
• Include manufacturer's certificate of analysis confirming the exact sulfonium compounds and aqueous formulation
• Label containers with GHS hazard pictograms and UN numbers for DOT/CBP hazardous materials compliance
• Avoid classification errors by distinguishing from polymer dispersions (3906) which lack these specific initiators
