1-7 Mailability Determination

If a mailer is unsure about whether an item is mailable or its packaging is acceptable, the mailer should send a written request to the nearest business mail entry unit (see DMM G042 for addresses). To ask for an exception to Postal Service packaging requirements, the mailer should submit a written request to an RCSC (see Appendix B for addresses). The request should fully describe the item and its packaging.
