DMM Revision: Minimum Paper Basic Weight Standards

Effective June 6, 2016, the Postal Service™ will revise Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®), section 201.3.2, to provide the minimum paper basis weight for envelopes or letter-size mailpieces sealed along all four sides.

On April 15, 2009, the Postal Service published a Federal Register final rule (74 FR 17399–17403) to revise section 201.3.0. In this revision, the minimum paper basis weight for envelopes or letter-size mailpieces sealed along all four sides was omitted. For clarification, the Postal Service is adding the 50-pound minimum paper basis weight or equivalent standard to section 201.3.2. We will also revise section 201.3 for consistency.

Additionally, we will revise sections 505.1.4.1 for consistency and 505.1.6.1a to correct a DMM reference error.

Although this clarification will not be published in the DMM until June 6, 2016, this revision is effective immediately.
