Exporting second hand machine to Germany, no EORI number

[Aphrabehn]

Hi, we are a small UK manufacturer and we are selling an old second hand agricultural machine to Germany for £12,000. The customer is just a small farmer so doesn't have an EORI number.

We normally use a shipper, but not having an EORI number might cause customs problems? Or maybe not because it's secondhand? Best way of doing this?

Cheers
