Exactly. In many devices, including switching supplies, a bit of attention (and a few very low-cost parts) will bring the devices into compliance. RFI suppression steps are in the data sheet / example circuit for nearly all components used in switching supplies, FWIW.

But just as firms want to be able to import steaks that have been made from cattle raised near polluted foreign rivers, firms import power supplies made with RFI-suppression parts omitted because someone along the way wants that $0.15 as profit and US regulators don't care.

Incidentally, a law was passed fairly recently that allows agricultural firms to remove information about where food items were produced, so quite possibly the steaks we eat will soon be made from cows who drink the water runoff from the polluting factories that make the low quality switching supplies.

Our "first world" environmental regulations (food quality, air and water quality, RF noise floor) are only as good as our regulation of imported products that commit fraud by selling products that do not comply. By failing to enforce these laws, US regulators have helped foreign firms cheat their way into the US market, putting US firms out of business and harming consumers indirectly by polluting their environment.

I'm not arguing that all of those regulations make sense, just that it is silly to have laws that we don't enforce when the health consequences and RFI consequences harm everyone.
