Quality and certification FAQs
What does ENF mean?
ENF is Ningfeng's formaldehyde-free bonding class, the strictest emission tier we offer, above E0 and E1. It has been in production since 2021 and is held across the full particleboard, MDF and HDF range.
What is the difference between E0 and CARB P2?
E0 and E1 are China and EU emission classes measured under their own test methods. CARB P2 is the US regulatory standard for composite-wood products sold into the United States. Ningfeng panels carry both, so the same board can ship to buyers who specify either system.
Is FSC certification available?
Yes. Ningfeng holds FSC chain-of-custody certification, alongside ISO 9001, ISO 14001, OHSAS 18001 and China Environmental Labelling.

Does every product carry every grade, or only some lines?
Every emission class on this page, from E1 through ENF, CARB P2 and JIS F★★★★, is held across the full range: particleboard, MDF and HDF, group-wide.
