Benelux market agreement expands Walker® exhaust business with Van Heck

The agreement includes an innovative distribution arrangement in which Tenneco Automotive will ship product pre-packaged from its European distribution centre directly to Van Heck's central warehouse, giving the distributor significant competitive advantage in inventory management, logistics and delivery lead times.

"We are very pleased to further expand our relationship with Van Heck with this incremental exhaust business," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "The ability to ship a broad range of exhaust products from one central source is a unique offering in Europe, and is the kind of differentiator that allows us to achieve new aftermarket business by bringing creative logistics solutions that help our customers better serve their customers."

Adrian Roggeveen, Chairman of the Van Heck Group, said: "Van Heck and its Business Partner Network want to work with Tenneco Automotive to achieve economies in the supply chain, which will benefit consumers. Our choice of Tenneco Automotive is clear - Tenneco is one of the largest OE suppliers. With its experience, the company can meet our Romax brand standards."

Tenneco Automotive's strength in coverage, product availability and central warehousing, combined with Van Heck's advanced e-business and data communications solutions, will be further reinforced with this new distribution system. The system will manage Van Heck's inventory and stock rotation by linking demand to Tenneco Automotive's production planning process.
