One new product -- we called it the Fredwriter -- was quite obviously above the Part 15 limits, and after I reported this, it was only a few weeks later that I got an angry call from a factory manager in China:

The case was upper and lower clamshells coated with copper bearing paint and snapped together, then secured with screws. The Chinese factory had some problems getting the halves to latch, so the factory manager talked to his buddy at the plastics factory and got cases made MINUS beveled interior features where the copper made contact, top to bottom...

Interestingly enough, I had, back in the day, devised a modification there, a piece of copper tape inside the case, to REDUCE the radiated power from a similar item my then-employer was importing.
