About California Proposition 65

California’s Proposition 65 requires that a clear and reasonable warning be provided prior to exposing individuals in California to certain chemicals and substances, including wood dust, that are known to the State of California to cause cancer, birth defects or other reproductive harm. We care about our customers' safety and hope that the information below helps with your buying decisions.

Trex products are a wood-polyethylene composite. As a result of the wood content in the product, individuals who drill, saw, sand or machine Trex products will be exposed to wood dust. In addition, Trex products contain trace amounts of other chemicals that are on the Proposition 65 list.

Your risk of exposure to wood dust and other chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.

In compliance with California Proposition 65, we are providing the following warning concerning Trex products:


WARNING: Drilling, sawing, sanding or machining wood products generates wood dust and other substances known to the State of California to cause cancer, birth defects or other reproductive harm. Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection.
