I don't see a diagram on page 13, but I read a few pages around there. I don't see anything about it not applying to micro-enterprises. I see one diagram (PDF page 14/page num 11) that says a farmer selling "under own name or trademark to end user in another Member State" (without saying there's an exception for a micro-enterprise) means that the "Farmer is producer," which sounds like the opposite of what you said.
