IS 710 vs Fake Marine Plywood

When it comes to furniture, kitchens, bathrooms, or any area exposed to moisture, marine plywood is often the top recommendation. But not all “marine plywood” in the market is truly marine grade. Understanding the difference between IS 710 certified plywood and fake marine ply can save you from costly repairs and poor durability.

What is IS 710 Marine Plywood?

IS 710 is an Indian Standard specification defined by the Bureau of Indian Standards for Boiling Water Proof (BWP) grade plywood. This is the highest quality plywood available for moisture resistance.

IS 710 plywood is manufactured using:

• High-quality hardwood veneers
• Undiluted phenol formaldehyde resin
• High-pressure bonding techniques

This ensures:

• Excellent water resistance
• High strength and durability
• Resistance to delamination even after prolonged exposure to water

Because of these properties, IS 710 plywood is ideal for:

• Kitchen cabinets
• Bathroom furniture
• Outdoor applications
• High-humidity environments

What is Fake Marine Plywood?

Fake marine plywood is often sold under labels like “commercial marine,” “MR marine,” or simply “waterproof ply” without any certification. These products are not tested or approved under IS 710 standards.

Common issues with fake marine ply:

• Use of low-grade or mixed wood
• Weak adhesive or diluted resin
• Poor bonding and finishing
• No standard testing or certification

As a result, such plywood:

• Swells when exposed to water
• Develops cracks or bubbles
• Loses strength quickly
• Requires frequent replacement

Key Differences Between IS 710 and Fake Marine Ply

1. Certification

• IS 710: Certified by BIS with proper stamp
• Fake Ply: No valid certification or misleading labels

2. Water Resistance

• IS 710: Can withstand boiling water tests
• Fake Ply: Fails under prolonged moisture exposure

3. Durability

• IS 710: Long-lasting, even in extreme conditions
• Fake Ply: Short lifespan

4. Cost vs Value

• IS 710: Higher initial cost but long-term savings
• Fake Ply: Cheaper upfront but expensive over time due to damage

How to Identify Genuine IS 710 Plywood

• Look for the ISI mark with license number
• Check for “BWP Grade – IS 710” clearly mentioned
• Buy from trusted brands and authorized dealers
• Avoid unusually low prices claiming “marine quality”

Conclusion

Choosing between IS 710 plywood and fake marine ply is not just about price—it’s about quality, safety, and longevity. While fake marine plywood may seem economical initially, it often leads to higher maintenance costs and compromised furniture life.

Investing in genuine IS 710 certified plywood ensures peace of mind, better performance, and long-term value—especially in moisture-prone areas.
