In other words, is an \"educated guess\"\nat the UN number acceptable, or are there specific steps and procedures that must be\nfollowed? What if the material is relatively new and has not been fully characterized?\nWhat if toxicity has not yet been determined? What sort of documentation and record\nkeeping are required?\nThank you for your assistance.\nSincerely,\nMICHAEL FiX\nMichael Fox, Ph.D.\nFounder\n9121 E.
