What special procedures are required to purchase Class II DEA controlled substances?
To purchase Class II controlled substances, it is necessary for the DEA registration holder to provide original copies of a DEA-222 form with the order. This requires that all purchase orders listing Class II controlled substances must be mailed (not faxed) to the supplier. Instructions for ordering DEA-222 forms can be found at http://www.deadiversion.usdoj.gov/faq/dea222.htm.
