Outsourced Logistics

WATERLOO, Ontario—November 26, 2008—Descartes Systems Group, a global on-demand software-as-a-service (SaaS) logistics solutions provider, has extended its relationship to provide Delta Cargo with technology underlying Delta Cargo’s electronic air freight booking portal at deltacargo.com.

Delta Cargo has selected Descartes’ GF-X Private Label solution to support deltacargo.com, a Delta-branded electronic booking portal for major freight forwarders and known shippers working with Delta Cargo. Deltacargo.com has been enhanced to offer full international route and product offerings in addition to Delta Cargo’s domestic freight booking service. Shippers may also book dangerous goods, human remains and pets through the portal.

Delta Cargo customers can use the private-label solution to book cargo through the www.deltacargo.com web site and query their shipment needs. The system responds with details on available cargo capacity and rates. When a cargo reservation is made online through the Delta Cargo web site, an electronic confirmation is delivered to the customer. Freight allocations can also be booked through deltacargo.com.

“We have been a long-time customer of the GF-X Exchange. Extending our relationship with Descartes to include a private-label portal is a natural progression for Delta and a commitment of our brand and service to our customers,” said Neel Shah, Vice President of Delta Cargo “Descartes’ GF-X Private Label allows us to provide advanced electronic booking functionality, any time day or night, for our customers using a cost effective and proven solution. This is an important part of our continued commitment to service our customers.”

“Delta Cargo is a global carrier with a long and established brand in air cargo,” said Ed Ryan, Executive Vice President, Global Field Operations for Descartes. “As operational costs increase and international trade grows, the need for automation and access to booking information and services in real time also grows. With Descartes’ GF-X Private Label, Delta can provide electronic booking capabilities via its web portal to reach forwarders throughout the world.”

Descartes GF-X Exchange is one of the largest electronic information and reservation systems in the airfreight industry. Airfreight carriers can distribute real-time product, routing, capacity and rate information to their forwarders worldwide. Airfreight forwarders can access carrier information, make electronic bookings and track shipments via a web browser, 24 hours a day, 7 days a week.

The Descartes GF-X Private Label service is a unique way for carriers to deploy a fully-featured electronic bookings channel without the higher costs and risks associated with in-house development in a way that utilizes existing processes and interfaces to the Descartes GF-X Exchange.

WATERLOO, Ontario— November 25, 2008 — Descartes Systems Group, a global on-demand software-as-a-service (SaaS) logistics solutions provider, responded to the new U.S. Customs and Border Protection (CBP) Importer Security Filing (ISF) “10+2” rule by forming a Descartes “10+2” Workgroup. The Descartes “10+2” Workgroup is designed for leading importers, customs brokers, carriers, freight forwarders, non-vessel operating common carriers (NVOCCs), and shippers — including representation from the top 5 integrators and leading international freight forwarders — to standardize and develop best practices across this global logistics community for this new rule.

Today, CBP officially released its long-awaited interim final rule on the Importer Security Filing, also known as the “10+2” rule. Under this rule, beginning January 26, 2009, importers will be required to provide CBP with additional data elements 24 hours prior to lading for all ocean shipments inbound to the United States. This security measure is often referred to as “10+2” because the regulation requires the collection of 10 new data elements from importers or their agents and two message sets from the ocean carriers. The goal is to have these data elements submitted 24 hours prior to vessel departure and the two new message sets from ocean carriers within 48 hours of vessel departure, however, CBP has allowed for some flexibility in this timing and submission of the data elements.

Descartes’ “10+2” Workgroup objectives are to:

• Automate and standardize this business process across all parties involved

• Provide the interpretation and understanding of the final ISF rule and its impact on the industry

• Provide insight on optimal data and work flow options between the importer, forwarder, broker, carrier, other agents and CBP

• Provide guidance on future complementary solutions to assist in further streamlining international trade

“The ISF 10+2 requirement is a multiparty process. The business process and work flows will need to be defined as they will be different across the multiple parties and therefore will not be a one size solution that fits all,” said Ed Ryan, Executive Vice President, Global Field Operations at Descartes. “Descartes’ role is to enable our global logistics community to help manage this process in the most effective and efficient manner.”

Descartes previously announced the availability of its Importer Security Filing (ISF) “10+2” Service to address the CBP interim final rule.

For importers, customs brokers, carriers, freight forwarders, non-vessel operating common carriers (NVOCCs), and shippers, the Descartes ISF Service offers a complete solution to help them comply with the new regulations. To accommodate customers’ varying technical capabilities, Descartes offers options that range from a user-friendly Web solution that permits manual entry of data information to a tightly integrated system-to-system electronic data interchange (EDI) connection. Regardless of the option chosen, Descartes ISF Service submits required data information electronically to CBP and gathers the status of that filing in real-time.

Descartes offers three different ISF Service delivery options accommodate varying customer needs:

• DESCARTES ISF: This simple web user interface (UI) enables customers to login via the Internet and enter all the data required for an ISF filing (5 or 10). This service sends the data directly to CBP and provides a view of the filing status. Customers have the option of receiving the status updates via EDI if they choose. E-alerts can also be used to notify the customers via email if there is a problem with the filing.

• DESCARTES ISF - CONNECT: This service enables customers to gather the complete data set for the ISF filing in their own systems for submission to CBP. The service transmits the data for each ISF filing and provides a status of the filing via electronic message for posting in the customer’s own system. All transmissions are made via the Descartes Global Logistics Network’s secure connection to CBP.

• DESCARTES ISF - PREMIER: This service enables the customers to collect the data needed for the ISF filing from multiple electronic document submissions or parties, including data sources such as a Purchase Order or ASN. Once the data is collected for the partial ISF filing, the customer can complete the remaining required fields and submit the filing to customs via the user interface as needed.

Descartes’ ISF Service is a part of the Descartes’ Global Logistics Network (GLN) Customs Filing & Compliance suite. The GLN helps automate, manage and streamline the end-to-end shipment process, from source to consumer, with ongoing real-time visibility. Descartes’ customs filing and compliance services help companies meet regulatory requirements for international shipments for both international customs agencies and security initiatives.
