Meaning
Air transport regulations define packaging instruction 966 as the mandate for shipping lithium ion batteries packed with equipment. This protocol applies specifically to cells and batteries that do not require an outer package containing only the power source. Shippers must ensure that the primary enclosure protects the battery from short circuits while remaining rugged enough to withstand normal handling conditions.
Equipment and batteries sit inside a strong outer container that meets international air transport standards for security and integrity.
Safety Constraint
The packing configuration mandates a maximum net quantity for each package depending on whether the batteries go via passenger or cargo aircraft. Lithium ion cells must remain at a state of charge not exceeding thirty percent of their rated capacity for air transport. Operators verify these values through documentation that accompanies the shipment from the origin to the destination.
Batteries stay secured against movement inside the outer packaging to prevent accidental activation during the transit cycle.
Compliance Mandate
Formal declarations demonstrate that the batteries comply with testing requirements found in the manual of tests and criteria. Labels on the outer surface communicate the presence of lithium ion technology to ground staff and flight crews throughout the logistics chain. Documentation must identify the specific instruction number to confirm the correct handling protocol.
Shippers bear the responsibility for providing this accurate technical information to the carrier before the aircraft departs.
Validation Protocol
Acceptance checks identify any discrepancies in the physical packaging or the accompanying dangerous goods declaration. Personnel inspect the outer box for structural damage or signs of battery leakage before moving the cargo to the aircraft hold. Proper adherence to these technical rules limits the risk of thermal events within the pressurized environment of an airplane cargo hold.
