Competent authority approval
Written permission from a national authority designated under dangerous-goods law to ship what the standard provisions do not allow. By air under the IATA DGR, prototype lithium batteries not yet tested to UN 38.3, or batteries over 35 kg on cargo aircraft, need approval from the State of Origin; by road, an authority can authorise conditions for critically defective batteries.
- Also called
- competent authority, State of Origin approval
Example
Vehicle and transport standards: an example situation
Shipping tests and vehicle battery approval tests address different uses; passing one does not automatically satisfy another.
Read Competent authority approval alongside Damaged and defective battery transport in this context. The dangerous-goods rules for moving lithium batteries that are damaged, defective or sent for disposal, set in ADR special provisions 376 and 377: specific packagings, and for batteries liable to react dangerously, packaging approved for that risk. A swollen or crashed pack is never shipped as an ordinary battery.
