If the labels or markings can still be read or identified, they are not sufficiently obliterated.
If labels or markings have not been sufficiently obliterated, the package must be handled as though it contains the indicated contents.
Examples of commonly reused boxes include cleaning supply boxes and liquor/wine/beer boxes. Some cleaning products are hazardous materials and alcoholic beverages are prohibited from mailing. Packages containing alcoholic beverages or with alcoholic beverage markings are prohibited in the mail.
If reusing a priority envelope or box, the postage charges will be for priority mail.
