So by that logic, there’s pretty much no animal that could be imported since the US has such a diverse environment. No fish/coral since it could be invasive to Hawaii. No tundra animals since they could be invasive to Alaska. Desert animals, no luck, Arizona and New Mexico. Even rainforest animals would likely be invasive to the redwood forests in California.
The part you miss is this applies to newly imported species....not ones we are already importing "more than a minimal amount". The only issue i have with it is they dont define "minimal amount".
