Almost no chance of you getting product insurance unless you have thoroughly vetted the suppliers and got your testing certs checked, in order and verified.
The business model of buying things on AliExpress and reselling is full of pitfalls, especially the sell first, buy later model. Not only can you risk your customers health but also its easy to infringe on Patents, trademarks etc. That doesn't matter to the people in China, but to the reseller your at major risk. Even if you have a limited liability company, you could loose the limited liability by not taking appropriate responsibility to keep your customers safe.

Re the other comment about people not being willing to sue in the US, absolutely not the case - in the US many lawyers offer no win no fee. And if you don't mount a defence they will steam roll over you. So you'd have a criminal conviction in the US if you ever went there. They do this on a numbers basis, if 1 out of 10 pays a settlement the lawyers still make money. This is why dodgy drop shipping sites have no contact us details.
