If he does decide to add some labeling he would be well advised to meet all legal requirements for it. So whether he has to legally or decides to as a gesture of good will to *some* customers, the method by which the labeling is done is exactly the same. Personally, I don't care if he labels, but I would care if the cost goes up because he does.
