It isn't plainly wrong as if they would allow much, then the share would be higher, as it is the case now for example Brazil (~9pc) or UK (>20pc).
If one think further, the share of export/import to/from non-eu countries is (rounded) 9pc of total EU's agriculture expenses. So, EU do not import much from US and others because they do not want certain techniques and methods and have their inner market and production anyway. Like it's the case with chlorine chickens and washed eggs. So, they don't allow such things to be sold to customers, which is infact not allowing import.
I guess you can claim that the 3rd-largest agriculture import source is "not much" if it is making you feel better about something. But I think that even the EU bureaucrats themselves would recognize that it is a very significant amount and continues to grow.
