Between 2004 and 2006, a shortage of drywall products forced many U.S. companies to purchase drywall from China. While this helped American companies continue to construct houses, buildings and apartments, the drywall was eventually deemed defective.

After the Chinese drywall was used in many new houses throughout South Florida and Virginia, home owners began complaining of a rotting egg stench. Unfortunately, the odor was unable to be eliminated and many were forced to leave their homes. In addition to causing this sulfur-like smell, the drywall also reportedly ruined wiring and air conditioning coils. Many homes were severely damaged, forcing owners to seek expensive repairs.

Many home owners are also concerned about the health effects associated with the defective drywall. While health officials are still determining any health problems the fumes may cause, some residents have reported headaches, irritated eyes, trouble breathing, sneezing and coughing.

Knauf Plasterboard Tianjin Co. Ltd. of China is at the center of the drywall problems. Reports have shown that the drywall may not have been immediately imported into the United States. Some of the drywall may have been held at the barges for months, where the humidity may have damaged the material.
