Japanese regulation for formaldehyde emissions from wood panels is widely considered the most stringent in the world. Their JAS standards for plywood and Structural Panels (OSB) do not directly specify a limit for formaldehyde emissions.
However, panels meeting the F**** standard for formaldehyde emissions (the most stringent requirement level) are required to have an average emission level below 0.30mg/l as tested to Japanese Standard JIS A 1460. APA PS 1 and PS 2 panels easily meet F**** requirements.
APA member products are exempt from the ‘Airborne Toxic Control Measure to Reduce Formaldehyde Emissions from Composite Wood Products’. Section 93210 (c) (8) of the measure specifically states that this excludes:
The CARB regulation was used as the basis for the Federal (US National) Regulation that comes into effect in 2013, therefore, the same exemption exists for the Federal (US National) formaldehyde provisions.
