No. International and federal regulations, as well as FedEx policy, prohibit leaving dangerous good packages at a drop box. Dangerous good packages must remain in a secure area, or under direct supervision of a responsible person until collected by the carrier/transport company. It is recommended to make arrangements in advance, as most carriers and transport companies provide two-hour pick up windows. FedEx will pick up the package directly from your lab or office free of charge. To schedule a pickup, contact FedEx: (800) 463-3369 or http://www.fedex.com/
