While cleaning my microwave oven at home the other day, I noticed a little metal badge on the inside with the model number, serial number, and some other information. At the bottom, it declared in capital letters:
“THIS PRODUCT COMPLIES WITH DHHS RULES 21 CFR SUBCHAPTER J.”
So I looked it up. The rule says, among other things, that appliances have to have little badges on them that say they comply with rule requiring the little badges. Perhaps this comes from the Department of Redundancy Department?
