Import Tips

• Ship with tamper-evident seals and include USP certificate to verify reference standard authenticity

• Declare exact quantity (typically <1g) and 'for laboratory use only' to qualify for research import exemptions

• Check DEA scheduling status as methyprylon derivatives may require import permit despite reference standard status
