Tampa Bay Home Inspections. New problems with Sulfur in drywall from China.
It has been reported that drywall imported between 2004-2006 from certain areas in China, can release sulfur-like odorous components. These compounds can corrode air conditioning coils and other copper-bearing materials, causing them to be replaced repeatedly. It has been determined that the problem is related to presence of iron disulfide. There have been reports that large quantities of drywall produced in China were kept on sea barges for months awaiting permission for importation to the USA. This drywall has a higher than typical density and a higher propensity to off-gas sulfur compounds.

Drywall is usually made of gypsum (hydrated calcium sulfate). Therefore, sulfur is one of the main components present in the sample. All drywall has sulfur in its elemental composition; therefore the odor is not explained by an analysis of the total sulfur content.
