Understanding IS Grades — The Most Important Thing to Know
Every legitimate plywood sheet sold in India should carry an ISI certification under one of these key standards. This IS number determines the water resistance of the adhesive used.
| IS Grade | Common Name | Resin | Waterproof? | Use |
|---|---|---|---|---|
| IS:710 | BWP / Marine | Phenol Formaldehyde | ✅ Yes | Kitchen, bathrooms |
| IS:303 | MR / Commercial | Urea Formaldehyde | ❌ No | Wardrobes, beds, TV units |
| IS:1328 | Blockboard | UF | ❌ No | Long shelves, doors |

How to Spot Fake or Substandard Plywood
- Check the ISI mark — It must be physically embossed on the sheet, not just printed on a sticker.
- Check the core layers — Look at the sheet edge. Good plywood has thin, consistent veneer layers. Rejected-grade boards have thick, uneven or hollow core layers.
- Smell test — Fake or low-grade boards often have a sharp chemical smell from excessive formaldehyde.
- Weight check — IS:710 marine plywood is noticeably heavier than IS:303 (due to denser PF resin bonding).
- Request the invoice — Legitimate dealers provide a GST invoice specifying the brand model and IS grade.
Frequently Asked Questions
Which brand plywood is best in India?
CenturyPly and Greenply are both excellent choices. For kitchens, always specify the IS:710 BWP grade from either brand. For wardrobes and dry areas, IS:303 MR grade from any ISI-certified manufacturer is adequate.
How do I check if plywood is genuine?
Look for the ISI mark embossed on the sheet surface. For CenturyPly, check the batch number using the QR code on the product warranty card. Buy only from authorized dealers who provide purchase documentation.
What thickness plywood for kitchen?
18mm IS:710 BWP for carcass sides, base, and top. 12mm IS:710 for internal shelves. Back panel can be 6mm HMR (High Moisture Resistant) board.
Is MDF good for wardrobes?
Not in humid coastal cities like Bhubaneswar, Puri, or Cuttack. MDF is moisture-sensitive and will swell over time. IS:303 commercial plywood is always the safer choice for wardrobes in Odisha.
