DHL Global Forwarding has been re-certified to IATA's CEIV Pharma standard.
The standard requires auditors to review certificated companies every three years.
At each location, IATA examines and compares the station's correspondence to its temperature control regulations (TCR), as well as GDP (good distribution practices) guidelines from the European Union, WHO and other regulatory bodies.
DHL began certifying its global stations according to the IATA CEIV Pharma Certification in 2016.
Following the independent audits and trainings for employees on site, DHL received the quality label for stations located around the world, including in Barcelona, Bogota, Tokyo and Chicago.
Thomas Mack, head of global airfreight at DHL Global Forwarding, said: "A resilient and highly efficient transport network, tailored to the specific needs of the Life Sciences and Health Care industry, has never been more crucial than today.
"Therefore, we are delighted to have received not only the re-certification for IATA CEIV Pharma on a corporate level, but also IATA's approval for our training program 'DHL Life Sciences Specialist'."
Nina Heinz, global head of network and quality, temperature management solutions at DHL Global Forwarding, added: "For years, the number of regulations and requirements has been steadily increased in the life sciences and healthcare industry in general, especially regarding product transportation and storage.
"Although we at DHL have been a leader in ideas and innovation in the industry for a long time, we recognise that there is always room to improve. With our renewed IATA CEIV Pharma Certification, we are both clearly demonstrating our continued emphasis on constantly enhancing our service quality and showcasing that we are a reliable partner for transporting vital and temperature-sensitive products."
