Citing a CRBA certificate (not obtained from a repository)

I live in Ireland and my recently born son was registered as a US citizen via a CRBA (Consular Report of a Birth Abroad). It's evidence of US citizenship. It results in a certificate that looks like [removed].

Now, I am very familiar with citing records that come from repositories (BMD records). But this recently received ceritifcte was sent to us from the US Embassy. I did not get it from an archive. 

How can I best cite this record? I'm also using Family Tree Maker.

Incidentally, I removed the image you supplied before publishing this, since we would not want that image publicly available to bad actors.
