Import Tips
• Lab packagings (<1kg) require child-resistant closure certification per Poison Prevention Packaging Act
• Include Lot Analysis showing trans/cis isomer ratio to prevent stereoisomer mixture classification
• Declare exact particle size distribution; ultrafine powders may trigger additional dust hazard declarations
