not sure what really is going on with your case but currently aliexpress is stopping quite some products from being sold and shipped to the US, especially those related to covid19 like masks etc. They're quite good at doing this and basically if they decide they dont allow something to be shipped to the US, there is nothing you can do to go around it because everytime you set the shipping address back to USA, no matter what other countries you revert it from before. If this is the case for you, then you may want to contact the seller directly and see if they can arrange something for you.Sometimes you may need to contact multiple suppliers until you find one who is willing to help.
