Import Tips
• Include end-use statement specifying laboratory analytical purposes only; avoid general chemical declarations
• Provide material safety data emphasizing extreme toxicity (LD50 10μg/kg) for proper hazmat handling
• Declare concentration (typically 1-10μg/mL in acetonitrile) to prevent classification as waste or diluent
