Can you send hairspray thru the USPS?

Answer 1

Aerosol cans cannot be mailed via airmail, per 1-800-ASK-USPS. They refered me to my local mail center for handling requirements, where my call was answered by a very friendly and helpful person. His instructions were that the can must be

• less than 33.8 oz,
• properly packaged by securing the aerosol from accidental release and/or puncture,
• packaged a box sturdy enough to withstand 70lbs stacked on top
• labeled with Surface Mail Only, ORM-D, and UN3180 on the address side (the UN3180 designation gives them an idea of what's inside the package)

see section 10 of the link below for more details on mailing Hazardous Materials:

Package Markings for Hazardous Materials

Each mailpiece containing a mailable hazardous material must be plainly and durably marked on the address side with the required shipping name and UN identification number. The UN identification number is not required on a mailpiece that contains an ORM-D material. A mailable ORM-D material must be marked on the address side with "ORM-D" or "ORM-D AIR," as applicable, immediately following or below the proper shipping name. The proper shipping name for a mailable ORM-D material is "consumer commodity." The designation "ORM-D" or "ORM-D AIR", as required, must be placed within a rectangle that is approximately 6.3 mm (1/4 inch) larger on each side than the designation. Mailable ORM-D materials sent as Standard Mail or Package Services must also be marked on the address side as "Surface Only" or "Surface Mail Only."
