（Question on Overpacking Lithium ion Batteries prepared per PI 965.）
Q.
Is it permissible to overpack multiple packages containing Lithium ion Batteries prepared following stipulations of PI 965?
According to IATA DGR, packages containing either Section IA or Section IB under PI965 must not be overpacked with dangerous goods of Class 1 (except Div. 1.4S) , Div.2.1, Class 3, Div. 4.1 and Div. 5.1. Similar restriction is spelled out in DGR 5.0.1.5.1.
We understand that Lithium ion batteries prepared under PI 965 are not permitted to be overpacked with dangerous goods listed above, but we would like to know if we can put multiple packages of PI 965 in one single overpack. We would appreciate your guidance. (31 Jan 22)
