What's to stop other countries from using this as a precedent to "inspect" USA businesses?
First up, China. Want to sell widgets or computer chips to China? Sorry, you will need an inspection.
The USPS for many years has had a presort verification auditor going up to Quebecor to verify processes they use to prepare mailings for the American market ~ if they pass that means the tens of millions of dollars in postage they pay in postage are being correctly computed (given the type, class, indicia and weight of the mail involved in a given mailing).
Believe it or don’t but I do it all the time. Foreign governments routinely inspect stuff before shipment
