Import Tips
• Verify product purity and composition via lab analysis to confirm it meets 'commercial ammonium carbonate' criteria with ammonium carbamate content
• Include safety data sheets (SDS) and end-use declarations to avoid misclassification as pharmaceuticals or industrial chemicals
• Watch for moisture content issues during shipping, as it can lead to ammonia gas release and customs holds
