There were several stamps from Belgium on the outside envelope from my Ebay vendor in Antwerp, and I looked them up in the Scott stamp catalogue.
P.S. —The stamps that I buy on Ebay from overseas still come through without getting a tariff slapped on them. The de minimis exemption* for goods purchased from overseas suppliers will end soon, though.
*Historically, the US has had a de minimis exemption that allowed goods valued below a certain amount (currently $800, subject to change) to enter duty-free. However, the US eliminated the de minimis exemption for products from China and Hong Kong on May 2, 2025, and plans to eliminate it for all countries on August 29, 2025.
