Mailing Compact Fluorescent Lamps
April 2008
PS-330 (601.10)
This
Customer Support Ruling (CSR) describes the conditions under which Compact
Fluorescent Lamps (CFL), also known as compact fluorescent light bulbs or
compact fluorescent tubes, are mailable.
The Domestic Mail Manual (DMM) and
Publication 52, Hazardous, Restricted
and Perishable Mail, do not address the mailability of CFLs. However, with recent increases in the use
of CFLs mailability questions have emerged.
CFLs
are manufactured articles containing minute amounts of mercury. The amount of mercury in an average lamp
does not approach the quantity that requires it to be transported as a
hazardous material under Department of Transportation regulations.
CFLs
are mailable when each article or apparatus contains 100 milligrams (mg)
(0.0035 ounce) or less of mercury and each mailpiece contains no more than
1 gram (g) (0.035 ounce) of mercury. Lamps are to be separated and cushioned to
prevent movement and breakage and must be enclosed inside a rigid outer
packaging. The package must be
marked, “Compact Fluorescent Lamps.”
