A federally funded study has found "a strong association" between imported wallboard made in China and metal corrosion in homes in the U.S., the Consumer Product Safety Commission says. Two other preliminary studies, of electrical-component and fire safety-component corrosion also support that finding, CPSC says. But no definitive tie has been found yet between the wallboard and health problems that home owners have reported.
CPSC, which released the findings on Nov. 23, says that it has received 2,091 reports from 32 states, the District of Columbia and Puerto Rico of possible health and corrosion problems that home owners say may be linked to Chinese drywall.
