Can I carry the liquid I bought at the duty-free shop on the plane?

pu1. It's okay that I bought it at the duty-free shop. It's completely sealed, so you don't have to open it and carry it in

OK

pu2. Sometimes duty-free items are restricted when passing through diesel, but it is rare. Even though it's a duty-free item, I've seen some restrictions on transit through Doha
