Is there an expert of custom and VAT refund?
As you knew Trump introduced new import duties (taxes) on products imported from Italy (and the most of World countries) to USA.
On top of that Trump abolished the De Minimis limit on small shipments. Before next 29th of August every import in USA below 800$ is duty free. From next week will be taxed with a rate depending by what you are importing.
That will impact the American online purchases done around the world, but even the purchases done by tourists traveling in Italy.
So everything purchased in Italy and shipped directly to US will be charged by the duties, even if are only 100$ of bottles of wine.
But my question is: what should happen to what I bring back with me in my luggage?
If is a little souvenir I could easily skip it, but if are alcoholics that must be declared? And if is something I have required the VAT refund before leaving Italy: will be taxed when I arrive in US?
