Import Tips & Compliance
• Document stabilizer type/concentration (<0.5%) in SDS to prove compliance with Chapter Note (f)
• Use nitrogen-purged packaging; oxygen exposure causes discoloration leading to rejection
• Declare 'stabilized for transport' status; unstabilized forms may require different hazard class
