That is precisely what a Profomia invoice is.
It’s item description, serial number, country of origin, value.
It’s pretty much an internationally accepted shipping declaration.
Once again I suggest you google the specifics.
I lived in Friboug Switzerland for 2yrs and bounced around Europe rolling out new IS infrastructure in chemical plants. We had locations in: Netherlands, Germany, France, Italy, Turkey, Sweden, UK. I then moved to Tokyo and did the same job in Asia.
I have shipped to all of those countries and more. I do know what I am talking about here.
