Import Tips
• Obtain proper hazardous materials certification as calcium hydride is pyrophoric and generates flammable hydrogen upon moisture contact
• Provide detailed chemical purity analysis and safety data sheets (SDS) to avoid misclassification as a metal or waste product
• Ensure packaging complies with UN standards for reactive solids to prevent customs delays
