The reason for this change was the IATA/ICAO decision to ban loose lithium metal batteries on passenger aircraft as of January 1, 2015. Following this, DHL Express decided to introduce the same ban to our network, which includes both cargo and passenger planes. As it is not possible to guarantee that a shipment will be placed on a cargo plane (due to the high amount of CAL used and the nature of the TDI handling process), the ban applies to the whole DHL Express network.
