From the perspective of the United States, mechanical royalties refer to the payments made for the use of a composition outside the United States. Generally, physical mechanicals outside the U.S. are not charged at a fixed penny rate like the U.S. statutory rate. Instead, they are paid as a percentage of the wholesale price. International mechanical royalties are one of the types of royalties that are often not collected by U.S.-based songwriters who do not have a publishing administrator.
