Yes, indeed. Luckily, I worked for a computer manufacturer and we could find other vendors. Still, I have found it advisable to add wording to purchase specifications, something like: "Product shall be compliant with <insert standard here>. Product shall not, when attached to an otherwise compliant equipment, result in non-compliance." However, one cannot rely on this sort of thing. Some foresight has to be exercised in designing I/O and power connections so that they do not rely for compliance on expected suppression in another piece of equipment. I have seen engineers who relied on EMC suppression in a printer to reduce emissions associated with a driver; changing to a different printer had them scrambling to deal with problems they'd left untreated. Anyway, the question you ask contains its own answer: Can you sell non-compliant products? No. If you tested it, you certainly knew that you were placing a non-compliant system on the market, and the authorities would look very closely at those who made the decision to do so.
