Delta Cargo,who last November declared that it would no longer accept shipments containing devices powered by lithium batteries in devices operating in the cargo hold (including those in temperature-sensitive shipments), has modified its position.

In a letter dated January 27, 2009 (attached below), Delta Cargo  agreed to take only approved devices. To date, Sensitech data-logging devices are the only ones approved. Sensitech has provided Delta Cargo with sufficient documentation to demonstrate that their devices meet the exception requirements provided in Special Provision 188 of 49 CFR Part 172.102(c)(1). 

Delta goes on to say that unapproved devices will not be accepted. It will be incumbant upon each individual data-logger manufacturer to prove that the lithium batteries in their devices are in compliance with the applicable Dangerous Goods regulations for content, configuration, application, and testing and/or meet the Special Provision exception requirements.  

I have kept my ear close to the ground on this issue and no other airline has taken Delta's hard-line stance. But, as I mentioned in Pharmaceutical Medical & Packaging News ColdChain Suppliment Winter/09 published earlier this month, all data logger manufacturers using lithium batteries will need to prove that their battery type meets the UN Manual of Tests and Criteria requirements (171.7) for voltage discharge rates, robustness in packaging, and lithium metal content, by October 1, 2009. Being able to prove that the batteries in their devices meet the Special Provision exception requirements can be done anytime. Companies would be well-advised to have this documented in advance, and at the ready.
