Environmental Certifications & Compliance

Meeting the toughest environmental standards! Committed to being earth-friendly. We can prove it.


Committed to a high standard of excellence, Timber Products’ commitment to quality spans more than just our products. We are proud to hold numerous reputable certifications from associations with high standards known and respected around the world.


Timber Products Company’s FSC® Chain of Custody (CoC) certification ensures that our products are made of material sourced from well-managed FSC® certified forest and other controlled sources that provide environmental, social and economic benefits. Implementation of FSC® Chain of Custody (CoC) certification provides for the production of FSC® chain of custody certified products and allows companies to label their FSC® products so consumers can choose products that support responsible forest management.


Sustainability Standard was developed by the Composite Panel Association (CPA) for manufacturers of composite wood or agrifiber-based panels made with particle board, medium density fiberboard (MDF), hardboard, engineered wood siding, and engineered wood trim. The standard includes using the CPA Carbon Calculator to assess the lifecycle and carbon footprint of composite panels made at a particular manufacturing plant. Both Ampine and Medford Particleboard meet this standard.

LEED V4 Credit Support

Leadership in Energy and Environmental Design (LEED) is the most widely used green building rating system in the world. The LEED Credit System is a global-recognized framework for healthy, efficient, and cost-saving green buildings. Timber Products qualifies for LEED Credits in the Low-Emitting Materials Category.

California Air Resources Board (CARB)

The California Air Resources Board (CARB) has set goals for attaining and maintaining healthy air quality, protecting the public from exposure to toxic air contaminants, and providing innovative approaches for complying with air pollution rules and regulations. All Timber Products facilities are CARB-Exempt, and our products meet the stringent CARB Phase 2 emission standards for formaldehyde emissions from composite wood products, including hardwood plywood, particle board and MDF.

UL Environmental Product Declaration (EPD)

An Environmental Product Declaration (EPD) measures and analyzes the carbon impacts of a product through a Life Cycle Assessment (LCA). EPDs can be used to compare environmental impacts between different products and can help decision makers select the best products for their projects. Timber Products has EPDs for our hardwood plywood, softwood plywood, softwood veneer, hardwood veneer, particleboard, Spectraboard, and MDF. Timber Products EPDs have the UL EPD certification Mark indicating that UL has independently reviewed and certified the manufacturer’s environmental impact disclosure that constitutes the EPD.
