Usually when a corporation is involved, criminal enforcement goes out the window. That aside, it would be an issue for regulators if they were marketing to consumers, but the "spec" in this case is usually part of the vendor contract and isn't legally binding except between the original supplier and customer. Putting up a bunch of rebinned "automotive grade" battery cells on eBay doesn't count because for many items it is assumed by default that the customer is qualified to use the equipment and raw battery cells fall squarely into that category.
