ISI 710 vs ISI 303 Plywood
IS 710 and IS 303 are the two Bureau of Indian Standards specifications behind most plywood sold in India — one for boiling-water-proof marine grade, the other for moisture-resistant commercial grade.
| Aspect | IS 303 (MR Plywood) | IS 710 (BWP / Marine Plywood) |
|---|---|---|
| Adhesive used | Urea Formaldehyde (UF) resin | Phenol Formaldehyde (PF) resin |
| Water test | Resists ambient moisture, not submersion | Passes a 72-hour boiling-water resistance test |
| Typical service life | Around 5–10 years in consistently wet conditions | Around 15–25 years, holding up under sustained moisture exposure |
| Typical cost | Lower | Higher |
| Best use | General interior furniture, dry rooms | Kitchens, bathrooms, exteriors, boat and marine work |
How to Check What You're Actually Buying
Look for the ISI Mark
A genuine ISI-certified sheet carries the ISI mark and a BIS licence number stamped on the edge of the board — ask to see it before buying.
Match the Standard to the Room
IS 303 is adequate for bedrooms and living areas; IS 710 is the right call for kitchens, bathrooms and anywhere water contact is likely.
Buy From an Authorised Dealer
An established dealer can show you the sheet's certification directly and won't substitute a lower standard without telling you.
Don't Assume Price Equals Standard
Always confirm the actual IS number stamped on the sheet — don't rely on the price or the brand name alone to infer the grade.
Both Standards, One Trusted Source
We stock both IS 303 and IS 710 certified plywood, so you can match the standard to the room rather than defaulting to one grade for the whole project. See our MR vs BWR vs BWP grade guide for how these standards map to the grade names you'll see on price lists, and our marine plywood guide for more on IS 710 grade specifically.
Frequently Asked Questions
What is IS 710 plywood used for?
IS 710 (BWP/marine grade) plywood is used wherever sustained moisture exposure is likely — kitchens, bathrooms, exterior applications and marine or boat-building work.
What is IS 303 plywood used for?
IS 303 (MR/commercial grade) plywood is suited to general interior furniture in dry rooms like bedrooms and living areas, where only occasional ambient moisture is a concern.
How do I know if plywood is genuinely ISI certified?
Check the edge of the sheet for the ISI mark along with a BIS licence number — a genuine dealer will show you this on request, and it's worth checking before you commit to a bulk order.
Is IS 710 plywood always better than IS 303?
It's more water-resistant, not universally 'better' — IS 710 costs more, so IS 303 remains the sensible, cost-effective choice for rooms that don't face regular moisture exposure.
Can IS 303 plywood be used in a kitchen?
It's not recommended for areas with regular water exposure like sinks and wet countertops — IS 710 (BWP/marine) grade is the safer choice for kitchen carcasses and cabinets.
