11 C.F.R. § 100.148
The payment by a candidate for any public office (including State or local office), or by such candidate's authorized committee, of the costs of that candidate's campaign materials that include information on or any reference to a candidate for Federal office and that are used in connection with volunteer activities (such as pins, bumper stickers, handbills, brochures, posters, and yard signs) is not an expenditure on behalf of such candidate for Federal office, provided that the payment is not for the use of broadcasting, newspapers, magazines, billboards, direct mail or similar types of general public communication or political advertising. The payment of the portion of the cost of such materials allocable to Federal candidates shall be made from contributions subject to the limitations and prohibitions of the Act. For purposes of this section, the term direct mail means mailings by commercial vendors or mailings made from lists that were not developed by the candidate. But see11 CFR 100.24 , 104.17(a) , and part 300, subparts D and E for exempt activities that also constitute Federal election activity.
