The Composite Wood Products Regulation is a California Air Resources Board (CARB) regulation that reduces public exposure to formaldehyde through the establishment of strict emission performance standards on particleboard, medium density fiberboard and hardwood plywood (collectively known as composite wood products). Environmentally Friendly Outdoor Deck
The regulation, adopted in 2007. Cheapest Composite Decking
established two phases of emissions standards: an initial Phase I, and later, a more stringent Phase 2 that requires all finished goods, such as flooring, destined for sale or use in California to be made using complying composite wood products. As of January, 2014 only Phase 2 products are legal for sale in California. Wood Plastic Composite Wall Panel

Any composite wood products contained in flooring products �C generally the underlying platform to which the laminate or wood veneer is affixed ? are required to be certified as complying with California��s formaldehyde emission standards. The companies that make flooring are required to label their flooring or their boxes of flooring as having been made with certified compliant composite wood products, to keep records to verify that they have purchased compliant products,and to inform distributors and retailers that their flooring is compliant with California��s current requirements (referred to as CARB Phase 2).
The Composite Wood Products Regulation establishes emission standards at levels intended to protect public health. We believe most laminate flooring and engineered wood flooring labeled as complying with California��s formaldehyde emission standards (i.e., CARB Phase 2) meets those standards. However some flooring products may have been falsely labeled.Various studies have shown that laminated and engineered flooring and sealed surfaces and edges reduce the emissions from the platform materials and that the emissions generally decrease as the product ages.? As a general rule, we do not recommend removing a flooring product unless there are noticeable health effects (i.e. nose and throat irritation, a burning sensation of the eyes,wheezing, and difficulty in breathing), and other measures (see below) taken to alleviate them have failed and there is good reason to believe the flooring is the source of the problem.
