Imported Drywall -- Conditions Associated with the Problem

Conditions currently associated with the problem of premature copper corrosion possibly related to imported drywall seem most likely to occur in, though not limited to, homes constructed after 2003 (especially 2006 and 2007). These conditions are indicative of the problem, but may not be inclusive of all the factors and may change in the future.

Specific conditions include:

  1. The presence of sulfur-like or other unusual odors in the home
  2. Confirmed presence of Chinese-manufactured drywall in the home
  3. Observed copper corrosion, indicated by black, sooty coating of un-insulated copper pipe leading to the air handling unit present in the garage or mechanical closet of home
  4. Documented failure of air conditioner evaporator coils (located inside the air handling unit)
  5. Confirmation by an outside expert or professional of the presence of premature copper corrosion on un-insulated copper wires and/or air conditioner evaporator coils (inside the air handling unit)

It is unknown at this time whether or not the problem of premature copper corrosion is caused strictly by any emissions from or effects of imported drywall, or whether any health effects are caused by the presence of the drywall.

As with any potential health concern, if you have any unsual health effects or symptoms, you should call or visit your physician or other primary care provider to help determine both the cause(s) and best path for treatment.

If you have two or more of the home conditions above, you should contact your home's builder or drywall supplier (if you renovated yourself), your home's owner (if you rent), and

the U.S. Consumer Product Safety Commission for more information.
