Import Tips
• Require detailed monomer analysis certificates proving allyl content >95% to match uncompounded allyl resin definition
• Declare as 'primary form, uncompounded' on entry docs to prevent confusion with finished monomers
• Avoid pitfalls by excluding shipments with initiators or stabilizers that could classify as compounded
