India's Mandatory Plywood Certification (QCO) Explained
India's Quality Control Order (QCO) for plywood makes BIS certification mandatory for covered products, aiming to push substandard, unlabelled plywood out of the market.
Four Things to Know About the Plywood QCO
What QCO Requires
Manufacturers of covered plywood products must hold a valid BIS licence and mark their sheets with the ISI mark before sale.
Why It Was Introduced
To curb the amount of substandard, mislabelled or untested plywood reaching consumers, and to bring manufacturing quality up to a consistent national standard.
What's Covered
General-purpose, structural and decorative plywood, along with marine, waterproof, fire-retardant and E-0 emission plywood, plus blockboard and flush doors.
What It Means for Buyers
It becomes easier to verify that a sheet has actually been tested to the grade it claims, rather than relying purely on a dealer's word or a brand name.
How to Identify Genuinely Certified Plywood
Look for the ISI mark and a BIS licence number stamped on the sheet's edge, and buy from an established dealer who can show this certification on request rather than taking a label at face value. As certification requirements phase in across the industry, buying from a dealer with a long, verifiable track record remains one of the most reliable ways to avoid substandard stock.
