Importation of night vision optics from Germany

[R711]

So, I’m trying to import night vision optics from Germany. They have only one requirement that a letter from the govt stating it’s legal to import. Does anyone know how to get such a letter or is a import certificate is all that’s required. They export the units into the USA with no issue.

Turns out it’s way easier to export optics and night vision out of the Netherlands then Germany.
