Import Tips
• Verify purity certificate (min 99%) and ensure chemical identity confirmed by GC-MS analysis to match metaldehyde tetramer structure
• Include Safety Data Sheet (SDS) and UN 1332 classification documentation for Class 4.1 flammable solid transport
• Avoid misclassification as general pesticide formulation; technical grade remains under pure chemical heading
