Import Tips
• Specify hydrate water content in invoice (57% min) to match technical specs and prevent weight disputes
• Pharma imports need DMF filing; common error is bulk packaging mistaken for industrial grade
• Temperature-controlled shipping mandatory (<30°C) to avoid decomposition during transit
