The Consumer Product Safety Commission (CPSC, or Commission) is announcing that, pursuant to the requirements of the Drywall Safety Act of 2012 (DSA), the Commission has determined that: ASTM C1396-14a, "Standard Specification for Gypsum Board," is a voluntary standard for drywall manufactured or imported for use in the United States that limits sulfur content to a level not associated with elevated rates of corrosion in the home; ASTM C1396-14a became effective less than two years after the enactment of the DSA; and ASTM C1396-14a was developed by Subcommittee C11.01 on Specifications and Test Methods for Gypsum Products of ASTM International. Based on these determinations, the sulfur content limit in ASTM C1396-14a shall be treated as a consumer product safety rule promulgated under the Consumer Product Safety Act (CPSA). Drywall manufactured or imported for use in the United States shall be subject to the general conformity certification (GCC) requirements of the CPSA.
