Formaldehyde is considered a health hazard, hence the wood-based panels must be within the limits imposed by the strictest regulations regarding the formaldehyde release. New national and international international regulations of formaldehyde emission from wood-based panels widely used in furniture industry were investigated in this study. The results of the study can be useful for the woodbased panel factories to follow the standards and regulations in terms of formaldehyde emission.

Formaldehyde emission is one of important issues in the wood-based panel industry. Recently, many countries tighten regulations on formaldehyde emissions emitted from wood-based panels due to harmful effect of formaldehyde on the humans. Urea-formaldehyde (UF) resin is the most used synthetic resin as binder in the production of wood-based panels for indoor applications. Disadvantages of UF resin are the formaldehyde emission and low water resistance. UF resin is classified according to the formaldehyde releases, Super E0, E0, E1, and E2, which are from lowest to highest, respectively. Many researchers have focused on the synthetic and natural formaldehyde scavengers for decreasing the formaldehyde emission from the wood-based panels. In this study, recent studies for reducing formaldehyde emission from wood-based boards were reviewed.
