WATERLOO, Ontario — July 11, 2006 — Electronic customs compliance technology acquired recently by logistics software and services specialist The Descartes Systems Group Inc. will help DHL Express Canada expedite cross-border shipments and meet the terms of Canada Border Services Agency's new Advance Commercial Information, or ACI, program and similar legislation pending in other parts of the world.

Descartes acquired ViaSafe Inc. and Flagship Customs Services Inc. (FCS) recently to add regulatory compliance as a service of its on-demand electronic logistics network, called the Global Logistics Network or GLN. Descartes said now its GLN can expedite cross-border shipments and help transportation providers, logistics intermediaries and government agencies comply with and enforce regulations impacting cross-border shipments.

Descartes said DHL Express Canada recently became the first air parcel carrier to use ViaTrade, compliance technology developed by ViaSafe which has been traditionally reserved for trucking companies. DHL Express Canada is using its ViaTrade Web interface to the GLN to transmit cargo manifest information at least four hours before aircraft arrival or at time of push-back for flights shorter than four hours as is required by the ACI program.

DHL Logistics has been using Descartes' GLN for about 10 years to exchange airway bills and status messages with air cargo carriers. DHL Logistics also has been using Descartes' visibility system built on top of the GLN for the past four years. DHL Express Canada became a ViaSafe customer last December, about six months before Descartes acquired the company and added ViaTrade as a value-added service of its GLN.

ViaTrade is designed to connect trucking companies to the pre-arrival processing systems of customs brokers in the U.S. and Canada and manage cross-border documentation processing requirements including customs filing. Descartes said airlines and air parcel carriers can use this same technology to reduce the time and effort it takes to clear customs in Canada and potentially in other countries with legislation similar to ACI pending.

"We believe electronic filing of shipment information in advance of the shipment's arrival will be mandated by governments around the world," said Oryst Dydynsky, vice president of cross-border and regulatory affairs at Descartes. "We've demonstrated through the use of ViaTrade by DHL Express Canada that the technology is multi-modal and that our GLN can help all types of customers comply with regulations that affect the tracking of shipment chain-of-custody and overall border security."

"Our ViaTrade Web interface to Descartes' GLN gave us the capability to be compliant for a regulatory change in Canada that went in effect June 26," said Chris Sheedy, director of international operations at DHL Express Canada. "We expect that by having Descartes integrate electronic filing technology and add a direct connection with Canadian customs we will be well positioned when the rest of the world begins to roll out similar legislation."
