There are four major international mainstream environmental protection standards now.
Formaldehyde emission content standards
A relatively widely used and well-implemented quality and technical standard internationally.
Divided into three grades: E1, E0, and ENF. E1 is a national mandatory standard in China and the entry standard for environmentally friendly boards. ENF is the highest standard in the current new national standard.
Divided into four grades. F☆☆☆☆ is the highest grade of environmental protection standards in Japan.
Divided into three grades: P1, P2, and NAF. The highest level is NAF, also known as formaldehyde-free exemption certification.

Higher environmental protection grade · Lower formaldehyde emission
According to the new national standard of our country, E Grades is divided into three levels: E1, E0 and ENF. E1 is a national mandatory standard in China, which is also the entry standard for environmentally friendly boards. ENF level is the highest standard in the current new national standard.
Therefore, when it comes to environmentally friendly boards, we consider at least the national standard E1 grade and the equivalent grades of other countries' standards. The following chart (for reference only) more intuitively ranks the different standards of various countries by grade. The closer to the top of the pyramid, the higher the environmental protection grade and the lower the formaldehyde emission.

Depending on the specific usage scenario and your budget, choose the environmental grade that suits you!
