How do I know if I have Chinese drywall in my home ?

Most drywall from China is labeled “Made in China.” However, it is possible that drywall from China may not have any markings. It is also possible that a home could contain both drywall made in the U.S. and drywall made in China. Homes that contain Chinese drywall were built after 2003 and meet two of the following criteria:

• The presence of sulfur-like or other unusual odors.
• Drywall labeled “Made in China”.
• Observed copper corrosion, indicated by black, sooty coating of un-insulated copper pipe leading to the air-conditioning unit. *

Professional confirmation / documentation of premature corrosion of air conditioning evaporator coils.

* Note: Freon, an agent commonly used in refrigeration and air-conditioning units may leak due to corrosion of the lines. Leaks common to this application do not typically pose any severe health risks.

Does Chinese drywall pose a health risk ?

Having Chinese drywall in your home does not mean you will certainly see effects on your property or health; however, preliminary data indicates that some lots of Chinese drywall emit gases that contain sulfur and other chemicals. These gases smell like rotten eggs and may irritate the respiratory system. Additionally, Chinese drywall is not known to cause any additional immediate or chronic health problems.

Some of the gases emitted from Chinese drywall can corrode metals, particularly copper. Corroded metals such as brass fittings, copper coils, and electrical wires may pose an immediate health risk because it could cause gas pipes to leak. NOTE: If you suspect you have a natural gas leak, contact your local gas company immediately. An extended safety issue would result as corroded electrical wires may cause smoke and carbon monoxide detectors not to function.

How can I treat my home if it is affected by Chinese drywall ?

There is currently no remedy other than complete removal and replacement of the drywall. Painting the drywall or using ozone generators or other masking agents/equipment are not effective remedies.

Who do I contact for more information on Chinese drywall ?

We would encourage anyone interested in more information on Chinese drywall to contact the U.S. Consumer Product Safety Commission via its toll-free consumer hotline: 800-638-2772.
