Import Tips
• Obtain EPA registration and fumigant labeling compliance for agricultural use; verify phosphide purity meets chemical definition standards
• Include safety data sheets (SDS) and UN hazard class 4.3 documentation for phosphine-generating compounds
• Avoid misclassification as ferrophosphorous (2848.00); confirm aluminum content via lab analysis
