The ISI standard for Boiling Water Proof (BWP) Marine Grade Plywood is referred to as ISI 710. It is made from high-quality hardwood veneers that are glued together using the Phenol Formaldehyde (PF) resin, which makes it very resistant to water and humid conditions.
The ISI 710 plywood is tested for 72 hours to see if it can withstand the effects of boiling water under the required circumstances, and it performs very well. Thus, the ISI 710 plywood is widely used where moisture is involved in the activities.
Some of the Uses
- Kitchen cabinets
- Under-sink storage cabinets
- Bathroom vanities
- Utility cabinets
- Laboratory furniture
- Hospital furniture
- Coastal home furniture
- Commercial kitchens

Differences Between ISI 710 vs ISI 303
Water Resistance Property
The main difference between ISI 710 and ISI 303 is the water resistance capability. ISI 710 wood is made up of layers with adhesive, which keeps them intact even under wet and humid conditions. It is best used in kitchens, bathrooms, and service areas. On the other hand, ISI 303 wood can only resist occasional moisture but not continuous moisture. Hence, it cannot be used in moisture-prone areas like kitchens, etc.
Type of Adhesive Used
The type of adhesive used while making wood plays a crucial role in determining its reaction during rainy and humid weather. ISI 710 wood uses phenol-formaldehyde resin, while ISI 303 wood uses urea-formaldehyde resin to make timber for dry furniture for interior purposes.
When it comes to comparing ISI 710 plywood vs ISI 303 plywood, it is one of the key aspects that develops the comparison. Another point of difference between plywoods is the durability. Marine plywood is made using specialised plywood that can face a lot of pressure placed on it. The life span of ISI 710 plywood is around 15 to 25 years or even more depending on various factors of implementation. On the contrary, the life of ISI 303 plywood is limited to 5 to 10 years if used properly in dry conditions indoors.
Differences in Durability
you are still comparing IS 303 vs IS 710 plywood, Another major difference between ISI 710 and ISI 303 wood is the dimensional stability of the plywood.
ISI 710 is made to hold its own under wet conditions, being completely unaffected by moisture or humidity. On the contrary, ISI 303 can survive well enough, but its strength weakens when exposed to moisture for a short period of time.
While ISI 710 does require a larger investment at the outset, it usually ends up being the better option in the long run, especially in places affected by moisture because of its sturdiness and lower maintenance cost.
Comparison of Plywood Grades: ISI 710 vs ISI 303. Which One to Choose?
The bigger number does not always mean the better wood. In fact, the plywood grade you should go for will depend on the specific job you plan to do. The most common question asked by homeowners is, which is better, IS 710 or IS 303?
