1. Will CARB supply manufacturers with a list of certified third-party certifier (TPC) testing facilities? We maintain a list of approved TPCs on our website. Currently, we have 33 approved TPCs throughout the world. For more information, please visit our list of TPCs on our composite wood products webpage.
2.As a manufacturer of composite wood products, do I need to be concerned if my resin supplier adds a pesticide (biocide) to the resin? Yes. CARB has become aware that some manufacturers or resin suppliers add a pesticide to their resin formulation to prevent bacterial growth. These pesticides may be included as a component of the resin formulation or an additive that is included at the time of composite wood panel production. All pesticides used in the United States or present in a product imported for sale in the United States must be approved for specific uses by the U.S. EPA. CARB has found that some of the pesticides used in resins have been approved by U.S. EPA for use in adhesives or in composite wood products. However, CARB has also found that some pesticides being used in adhesives or composite wood products have not been approved by U.S. EPA for that use. CARB suggests that manufacturers should verify with their resin supplier that any pesticides used in their resins are approved by U.S. EPA for this use.
