A federal consumer protection agency has established limits on the use of sulfur in drywall.
Effective July 22, the U.S. Consumer Product Safety Commission stipulates that drywall manufactured or imported in the U.S. must not exceed 10 parts per million of orthorhombic cyclooctasulfur. That cap is currently a voluntary industry standard.
The commission began investigating drywall in 2009 following homeowner complaints, finding sulfur content in excess of the that threshold led to accelerated corrosion of copper and silver in homes.
The sulfur limit was required as part of the federal Drywall Safety Act, which was signed into law in early 2013.
