（Please explain the definition of Section IA spelled out in the Introduction of PI965.）
Q.
Immediately following INTRODUCTION at the start of PI 965, the first bullet point gives the definition of Section IA. It reads;
“Section IA applies to lithium ion cells with a Watt-hour rating in excess of 20 Wh and lithium ion batteries with a Watt-hour rating in excess of 100 Wh, or to quantities of lithium ion cells or batteries in excess of those permitted in Section IB of this packing instructions which must be assigned to Class 9 and are subject to all of the applicable requirements of these regulations.”
There is a similar entry at the same location in PI 968 for Lithium metal batteries which reads:
“Section IA applies to lithium metal cells with a lithium metal in excess of 2 g, or to quantities of lithium metal cells or batteries in excess of those permitted in Section IB of this packing instructions which must be assigned to Class 9 and are subject to all of the applicable requirements of these regulations.”
Even reading PI 965 and PI 968 very carefully, you cannot find a quantity restriction or package count restriction. With PI 965, only the package limit for CAO is stated as 10kg per package, and for PI 968, 2.5kg per package. There is no limit to the number of packages. Therefore there is no quantity limits that corresponds to the statements in PI 965 and PI 968. Please guide us on what is the meaning of “quantities of batteries permitted in Section IB”? (30 Jun 17)
A.
Your assumptions are not wrong. Section IB of both PI 965 and PI 968 have no quantity limits nor package count limits. If a shipper wants to ship more than 10kg of lithium ion batteries, he can use as many number of packages each containing maximum 10kg. The same thing with lithium metal batteries. He can make as many 2.5kg packages.
This phrase is not carried in the ICAO Technical Instructions. It has been added by IATA. There are shippers who wishes to ship a large quantity of Section IB batteries and he chooses to use a UN Specification Section IA package. This phrase allows him to use Section IA packagings instead of multiple Section IB package. He would be able to ship maximum 35kg of Section IB batteries in a UN Specification package.
1) Liquid substances with a vapor inhalation toxicity of PG I cannot be transported.
2) Liquid substances with a mist inhalation toxicity of PG I may be transported by CAO aircraft provided they are packed satisfying PG I, and the net quantity per package is no more than 5 L.
3) If liquid substances with a vapor inhalation toxicity of PG I is confined to less than 5L per package, it can be transported on CAO aircraft.
