IT’S WHAT’S INSIDE AND HOW IT’S PACKED Make sure that your packages are safe for mailing by packing them properly. Follow these simple guidelines: Liquids, Powders and Perishables Place liquids in sealed, leak-proof containers and cushioned in material sufficient to absorb all leakage. Packages must be marked as containing liquids. Place powders in sift-proof packaging to prevent any leakage. Mail perishables only if they can reach their destination in good condition and are packaged to protect and secure the contents. Fragile Items Place glass, fine china and other fragile items in packaging cushioned to prevent breakage during transport. Hazardous Materials Few hazardous materials are permitted in the mail. Those permitted are subject to specific labeling, packaging, and quantity requirements. Prohibited Materials You may not mail items such as fireworks, fuel, alcoholic beverages and handguns.
