I did notice a lot of caveats on the US listings -some saying you have to be an authorized trainer or such and some other things ...I was going to review these and copy some onto my listings
Americans are remarkably paranoid.
Don't copy their descriptions and prohibitions. Many of them have no basis in fact.
Do your own research.
And if your buyer is not a CPR trainer, just having the dummy in his den as a decoration is not illegal.
Actually, to side eye the whole question, it is the buyer's responsibility to know what can and cannot be imported. Not the seller's.
