I work in th food industry. We are missing products from China that are hard to replace (price wise and other factors). For the other products I see a slight increase in demand but nothing we can't handle.
I visit most of Brooklyn's Kosher groceries every week, I see some items missing. We can expect all products from overseas where a Mashguiach is needed to fly to (a restricted country), to be oos which put some challenges to replace because we got use to the globalization (the way it should be).
