70 Pa. Code § 21.11
(b) If a person manufactures, packs or distributes a commodity at a place other than his principal place of business, the label may state the principal place of business in lieu of the actual place where the commodity was manufactured or packed or is to be distributed, unless the statement would be misleading. If the commodity is not manufactured by the person whose name appears on the label, the name shall be qualified by a phrase that reveals the connection such person has with such commodity, such as ‘‘Manufactured for and packed by
’’, ‘‘Distributed by ’’, or other wording of similar import that expresses the facts.
