Vinyards interested in Exporting

I am sure you are aware that every region in Italy produces wines. So, I suggest focusing on which region of Italy you want to import wines from . Then do a search on line of wine producers associations to find out which wineries is looking for distributors and, lastly , visiting them to taste their wines. I may have missed the point on how you want to import wines without get to know the producers and tasting their wines first. tasting
Another suggestion is to attend regional wine events .
A couple of years ago I attended a pre Amarone release tasting in Verona and discovered numerous wineries looking for importers. In that same city, there is VinItaly every year in April where wineries from all over Italy showcase their wines as it is attended by buyers from all over the world. So my primary suggestion in your desire to import wines from Italy would be to attend VinItaly, which is one of the largest wine events in the world where you can make connections with and taste wines of wineries across Italy.
Hopefully this helps
