US FBA Sellers- any trouble finding insurance?

I just acquired an FBA store but I’m having an absolute bear of a time finding business insurance, which is a prerequisite for Amazon to approve the transfer. Most insurance companies balk when I tell them I have products manufactured offshore with my brand, then sell in the US.

I thought this was a super common fact pattern so I’m just surprised/annoyed that I can’t get it squared away!

What has been your experience with business insurance as a quasi-manufacturer?
