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
