Under statutory restrictions in Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®), subsection 703.1.6.11, products that are mailed at the Nonprofit USPS Marketing Mail® prices must meet at least one of three exceptions. A low-cost item is one of the exceptions referenced in the Internal Revenue Code. Each year, the Internal Revenue Service determines the value of a low-cost item — the actual cost to the authorized nonprofit organization — and adjusts the value for the cost of living. For 2018, the value of a low-cost item is $10.90 or less.
