The requirement (to have the Type A paperwork) originates with the USDOT regulations. See 49CFR173.415(a) which states, in part "Each offeror of a Specification 7A package must maintain on file for at least one year after the latest shipment, and shall provide to DOT on request, complete documentation on tests and engineering evaluation or comparative data showing that the construction methods, packaging design, and materials of construction comply wit that specification." Your state inspectors are just trying to verify that the shipping container meets the USDOT requirements for shipping hazardous materials.

Thanks for the replies on this, but I am not looking for the IAEA
Certificate of Competent Authority. What is needed is the DOT 7A paperwork
on the Gulf Nuclear transport container used with the 71-1 three and five
Curie AmBe well logging neutron sources.
I think I have seen this document at one time or another, but cannot now
locate same. Our state regulators are upset since nobody seems to have a
copy, yet apparently a copy must be with the shipping papers to be legal.
Scores of these transport containers are in daily use all over the US. Has
anybody else run into this problem?
This is the cylindrical "pig" with an inner and outer steel wall and
containing either WEP or borated foam. The older spherical version
contained paraffin, and it is my understanding these devices are no longer
permitted as 7A containers.
