First, who are you purchasing the "profiler" from? I used to work for one of these companies so I can maybe give you someone to talk to.
And the regulator or government wont provide you any certificates that I know of. Here in the US the states or the NRC approve sealed source device registries submitted by the manufacturers. Its best to ask the company first for something like this, but there is really no reason for you to have it, since it gives you detailed drawings of its construction. And its been my experience that the only reason folks really want that is to perform "work" on a device they are not licensed to perform.
As for certificates for importing this device, ask specifically for the "special form" certificate for the source you are buying and it doesnt hurt to ask for the original sealed source certificate (it is a form which shows original assay date, actual activity, etc.) that is provided by the sealed source manufacturer. If you call the device manufacturer directly they will tell you all of this too and be able to get you the information you need.
