Import Tips & Compliance
• Require supplier CoA specifying anhydrous status to differentiate from monohydrate and avoid reclassification
• Package in moisture-proof containers; declare as corrosive solid (UN2679) for IMDG/IATA compliance
• Monitor for impurities exceeding 0.5% which could shift to 2825.90 if considered complex
