Import Tips
• Include lot analysis certificate with impurity profile; research quantities typically exempt from pesticide registration
• Small package sizes (<1kg) reduce scrutiny but require proper lab destination documentation
• Distinguish from technical grade via HPLC purity certificate showing single tetramer peak
