Import Tips
• Include end-user statements from accredited labs/universities to demonstrate legitimate research purposes
• Batch documentation must specify density (13.534 g/cm³) and surface tension values for quality verification
• Avoid generic 'chemical' declarations; specify 'mercury, elemental' to prevent hold at customs
