Every shipment that is being exported needs a commercial invoice so customs will be able to assess both the content and value of your shipment. A commercial invoice can be made on your department letterhead. The invoice must state a ship to and from address, description of what you are shipping, quantity, value of shipment and the reason for shipping. Environmental Health and Safety can help evaluate export requirements involving research materials prior to shipping. Please process these shipments through eShipGlobal. For assistance with exports not involving research materials please contact Don Deyo, Director of Corporate Contracts and Export Control Licensing, at 203-785-3817.
