The Lacey Act

So what exactly is this infamous Lacey Act, and how does it specifically affect reptile shipments?

I read it for the umpteenth time today, and aside from specifics on protected or endangered wildlife, I just don't see anything that actually addresses labeling, what must be labeled, and how to label, aside from "follow industry standards".

We have been shipping for 16+ years, thousands and thousands of packages, and we have never labeled a package with species info. I know hundreds of other breeders that don't label a package either. In our run up to our new business, we have encountered snake and reptile shippers that ship 500+ packages A WEEK, and they aren't labeling anything, so the very vague "industry standard" certainly seems to be met- no labeling.

I see posts and references to the "Lacey Act" but can someone give more specifics on what is legally required, and not just regurgitations of what we have all heard over the years?
