The tricky thing is that these are "temporary". It takes a month+ to ship (pack, load, cross the Pacific, unload) something from China and clear customs in the US. If there isn't clarity on how long the 30% tariff is in place it'll still be tough for companies to pull the trigger on importing things.
I know bigger companies like Hasbro *might* have import/export holding companies in China where items could technically clear customs before they ship, but I have no idea if Hasbro does this or if their stuff clears customs at the final destination.
Let's hope Hasbro has a bunch of stuff they can clear quickly and keep prices reasonable.
