DMM REVISION
New Packaging Option for Liquids in Glass Containers
Effective November 9, 2006, we are revising the Mailing
Standards of the United States Postal Service, Domestic
Mail Manual (DMM®) to allow mailers of nonhazardous liquids in breakable containers to use packaging certified by
the International Safe Transit Association (ISTA). The revised standards will provide mailers with more packaging
choices while ensuring that nonhazardous liquids in breakable containers are mailed safely.
Under the current standards, mailers must triple-package breakable containers (such as glass containers) that
contain nonhazardous liquids. Under the revised standards, mailers may continue to triple-package such material according to existing instructions, or they may use
packaging certified by the ISTA as able to withstand transportation through a parcel delivery system. Our engineers
tested packages certified as having passed ISTA Test Procedure 3A and found that those packages can be transported through the mailstream without leakage.
