With ~70% of India's plywood market unorganised, the grade stamped on a sheet isn't always what's inside. Use this checklist to tell genuine boards from fakes.
1. Check the IS / ISI mark
Genuine boards carry the BIS/ISI mark with the correct number — IS:710 for marine/BWP, IS:303 for MR/BWR — plus a brand name and batch details. No mark, no trust.
2. Inspect the edges
Look at the core layers: they should be even, tightly packed and free of gaps or overlaps. Hollow patches mean weak spots and poor screw-holding.
3. Weigh it
A genuine hardwood-core board feels dense and heavy for its size. Suspiciously light sheets often hide soft, low-density cores.
4. Do a boiling/water test
For marine claims, a sample boiled or soaked should not delaminate or swell. Reputable dealers won't object to a small test.
5. Check the surface & warranty
The face should be smooth, crack-free and well-sanded. Genuine brands offer a written warranty — get it on the bill.

How can I tell if plywood is genuine?
Check the IS/ISI mark and number, inspect the edges for a gap-free core, feel the weight, do a water test for marine claims, and buy branded with a written warranty.
Does heavier plywood mean better quality?
Usually — a dense, heavy board indicates a solid hardwood core, while very light sheets often hide soft, low-density cores.
Can I water-test plywood before buying?
Yes. For marine/BWP claims, a soaked or boiled sample should not swell or delaminate. Reputable dealers allow it.
