FedEx Battery Shipping Practice Test 2026 – Complete Exam Preparation

The outer packaging for UN3480 lithium ion batteries under Section IB must be strong and rigid. This requirement is about providing a protective shell that can withstand the rough handling, stacking, and transit shocks that occur during air transport, helping prevent damage to the inner packaging and reducing the risk of leakage or short circuits. Flexible pouches don’t meet this rigidity standard, and while a wooden crate is a rigid option, the rule isn’t limited to crates or to any vague “protects the contents” phrasing—Section IB specifies a strong rigid outer container to ensure consistent, tested protection. By using strong rigid outer packaging, you align with the safety and regulatory criteria for these batteries.
