By working with resin makers, we have developed a range of Customwood® products that meet the exacting Japanese Industrial Standards (JIS) for formaldehyde emissions. The superior grade, F4 Star (also known as Super E0), has formaldehyde levels similar to wood. Customwood® also complies with the equally rigorous California Air Resources Board (CARB) limits on formaldehyde emissions. This represents a de facto national standard for the US.
