California Perchlorate Label
Perchlorate Label
Some mobile phones use an internal, permanent backup
battery on the printed circuit board that may contain very
small amounts of perchlorate. In such cases, California law
requires the following label:
"Perchlorate Material – special handling may apply. See
www.dtsc.ca.gov/hazardouswaste/ perchlorate."
There is no special handling required by consumers.
