European Customs Filing Complements Global Logistics Network’s Existing US and Canadian Capabilities

WATERLOO, Ontario—October 1, 2008—Descartes Systems Group, a global on-demand software-as-a-service (SaaS) logistics solutions provider, has acquired Dexx, a Belgium-based European customs filing and logistics messaging provider. Dexx adds European customs filing capabilities and a community of connected European logistics organizations to Descartes’ Global Logistics Network of over 4,000 connected members.

Dexx’s customs offerings help shippers, cargo carriers and freight forwarders manage the movement and submission of customs filings and messages to a number of customs authorities. Dexx’s commitment to automating logistics processes in Europe also resulted in its membership in EuroTradeNet (ETN), an entity designed to promote electronic trade focused on customs filings in the European region.

In addition to customs services, Dexx manages the Brucargo Community System (BCS), the cargo community system (CCS) at Brussels airport. BCS provides a comprehensive range of electronic information exchange between airlines, integrators, general sales agents, forwarding agents, ground handlers, truckers and shippers, as well as customs and other governmental bodies.

“With anticipated upcoming European Union regulations expected to mandate electronic notification to custom authorities of the contents of a vehicle, aircraft or vessel prior to the arrival at the border, we saw an opportunity to play an exciting role in this market by combining our local expertise with Descartes’ Global Logistics Network,” said Johan Deckx, president of Dexx. “Descartes and Dexx share a common vision to automate customs compliance and other logistics processes, so we’re confident that our customers will continue to receive excellent service. We’re excited about joining the Descartes team and continuing to work on these important initiatives.”

“We’re committed to helping our Global Logistics Network customers comply with existing and pending electronic customs initiatives,” said Art Mesher, CEO at Descartes. “As logistics standards and government regulations around the world continue to evolve and be adopted, we pride ourselves in helping our customers be ready before compliance is mandatory. Our combination with Dexx is true to our mission of bringing together shippers, transportation carriers, forwarders, government agencies and other logistics intermediaries to streamline the shipment management process.”
