202 CMR, § 3.06
Any package kept, offered, or exposed for sale, or sold, at any place other than on the premises where packed shall specify conspicuously on the label of the package the name and address of the manufacturer, packer, or distributor. The name shall be the actual corporate name, or, when not incorporated, the name under which the business is conducted. The address shall include street address, city, state, and ZIP Code; however, the street address may be omitted if this is shown in a current city directory or telephone directory. The requirement for inclusion of the ZIP Code shall apply only to labels that have been developed or revised after July 1, 1968.
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 such statement would be misleading. Where 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 "Manufacture for and packed by _____," "Distributed by _____," or any other wording of similar import that expresses the facts.
