Import Tips
• Verify that the resin is in primary powder form and that thiourea and formaldehyde monomers exceed 95% by weight
• Declare the resin's end-use (e.g
• adhesives) to the CBSA, as this may affect classification
• Keep technical documentation showing the resin is not a chemically modified polymer that would fall under a different subheading
