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 consumer.
