Manuals – Media Mail
UPDATED August 2012
This Customer Support Ruling discusses
the eligibility of manuals at the Media Mail rates of postage.
Domestic Mail Manual (DMM) 173.4 provides that books
mailed at the Media Mail rate may contain no advertising matter other than incidental
announcements of books. In the past, some shop manuals and auto repair manuals
were not accepted at the Media Mail rate as books because brand name references
were viewed as advertising or because they were produced by the manufacturer of
the product. The parts references and manufacturers' names are essential to
the accuracy of the service instructions. They are not referenced for advertising
purposes. The product and brand names are not disqualifying for this rate,
nor is the fact that they may be produced by the manufacturer of the product.
