In the second bullet point of DGR 10.7.1.3.2 “Excepted Packages of Radioactive Material of Class 7” the full names and full addresses of the shipper and consignee must be indicated on the surface of the packages. SAG-06 also indicates their telephone number must also be shown. Please take a note of that.
As for your question on: “Dangerous Goods as entered on the DGR includes radioactive material, excepted packages. Am I correct?” I think you meant to say “as entered on the DGD” and not “DGR”. With shipments of Magnetized Material as well as of UN3373 Biological substance, Category B where DGDs are not required, you still need to indicate on the packages the names and addresses of the shipper and consignee.
Furthermore, the name of the consignee required per SAG-06 is the name of the true consignee. In case of a consolidation, it is the name of the consignee on the HAWB and not of the forwarder or breakbulk agent. Since most shipments from Japan are consolidations, misunderstandings do occur. Shippers and consignees are meant to be the true shippers and the true consignees. It is not the name of the forwarder or breakbulk agent.
