Items Eslpod Shipping Usps Rules Apply Small Allowed

The United States Postal Service (USPS) has a long list of "shipping restrictions" (rules about items that cannot be shipped, or may be shipped only under certain conditions) and "prohibited" (not allowed) items. Some of the rules apply only to international shipments, and a "subset" (a smaller group) of those rules apply to "domestic" (within the country) shipments.

For example, "aerosols" (cans whose contents are under a lot of pressure, released in a spray by pressing a small button) like "hairspray" (a liquid used to keep one's hair in a particular style) and "fire extinguishers" (spray bottles filled with chemicals used to put out fires) are never allowed in USPS mail, because they "carry" (have) the risk of "explosion" (blowing up; breaking into small pieces in a sudden and violent way). "Matches" (small sticks with tips used to produce a fire) and "lithium batteries" (items using a particular chemical to provide power to electronic equipment) are not allowed in the mail because they present a fire "hazard" (danger).

Alcohol and most cigarettes and other tobacco products cannot be sent through the mail. If someone reuses a box that originally was used for alcohol, all labels for the alcoholic beverage must be "removed" (taken off) before the box can be sent through the mail.

Certain live animals, like insects and "reptiles" (animals like lizards) can sometimes be sent through the mail, but there are many packaging requirements and they can be sent only when "adequate" (sufficient; meeting the minimum characteristics) is available. Finally, "perishable items" (items like food that will "spoil" (go bad) quickly) may be sent, but only "at the sender's risk" (with only the sender being responsible if the items are in poor condition when they arrive).
