The Postal Service and United States Postal Inspection Service (USPIS) state they have observed an increased frequency of incidents involving containers of liquids rupturing during shipment. This typically results in damage to surrounding mailpieces and to Postal Service equipment.
When responding to incidents involving liquid spills, Postal Service employees frequently note that mailpieces containing liquids are often not marked on the outer mailing container as required by DMM 601.3.4.
Many of these leaking mailpieces contain plastic bottles or other plastic containers and shippers apparently do not consider these to be breakable.
Therefore, the Postal Service says shippers are not cushioning the plastic containers with absorbent materials or include secondary containers as specified in DMM 601.3.4.
