Import Tips
• Store below 10°C during transit to prevent coagulation, with temperature logs for insurance and customs claims
• Declare exact chemical composition (CAS numbers) to facilitate EPA reviews for import permits
• Bundle with developer kits only if invoiced separately to avoid 'set' reclassification
