The Code of Federal Regulations, 21CFR Part 1301.74(b) requires distributors of controlled substances to design and operate a system to identify suspicious orders. Suspicious orders may include those of unusual size, deviating substantially from a normal historical pattern, and/or orders of unusual frequency. The following “Know Your Customer” Due Diligence Form allows MWI to obtain the necessary data to reasonably review your controlled substance activities and to assist you in protecting your interests as well. Because this is a requirement of the DEA, controlled substance orders may not be placed until this one page form has been completed in full and reviewed by the MWI Credit Department which handles account maintenance.
