NEW Self-Folded Mailer (FSM) Requirements

Understanding the new tabbing requirements is vital to a successful mailing project.

In collaboration with the mailing industry, the Postal Service engaged in a mailpiece design study to revise Folded Self-Mailer (FSM) standards for automation letter-size formats. As a result of those learning’s, the revised mailing standards introduce more creative mailpiece design options that better match with mail processing capabilities.

These revised mailing standards were presented in a Federal Register Notice of Final rules published on December 01, 2011 and were effective on January 05, 2013. Your KCI representative can help you meet all aspects of the new rules. Please contact them before producing your project.
