Reminds me of when I saw the customs declaration they had to make for the Troll oil platform[1]. It was "a thing" made here in the country, and it was being transported out of the country, so of course they had to customs declare it...

The declaration essentially said "one oil platform, unpackaged".

There was a suitable tariff code for it, but the value of it was so great the electronic customs declaration system couldn't handle all the digits.

Instead they had to write the value as a free-text comment.
