Kuehne+Nagel has expanded its Cool Corridor network for temperature-sensitive healthcare logistics by adding four new airfreight routes between Frankfurt and Atlanta, Chicago and Narita, Brussels and São Paulo, and Chicago and São Paulo. The Cool Corridor network is designed for vaccines, peptides, biologics and other temperature-sensitive pharmaceuticals. The dedicated transport routes combine GDP-compliant handling with tightly controlled transfer processes to minimise Time Out of Range (ToR) throughout the shipment journey. The company said the expansion reflects its strategic focus on strengthening healthcare logistics. Working with airlines and ground handling partners, Kuehne+Nagel will continue to expand the Cool Corridor network in response to customer demand while providing GDP-compliant end-to-end transportation.
