Marine Plywood
IS 710 BWP marine plywood, dispatched from a port city.
The one grade where a buyer is right to be paranoid — it is going somewhere wet, and a wrong spec shows up years later as delamination. Kerala's boatbuilding belt is what trained us.

Our BWP marine plywood is produced under the BIS licence of the mill that makes it. We work with several approved mills and each holds its own licence, so the CM/L number that applies to your order is named on the quotation — check its status and scope in BIS Care before you confirm. IS 710 requires an adhesive conforming to the BWP type of IS 848; it does not mandate one resin chemistry. The licence number and test documentation are stated on the quotation.

Why this board
Marine ply fails at the glue line and the gaps. We close both.
Kerala's boatbuilding belt — Beypore, the Vembanad houseboat yards, the Tuticorin repair sheds — is what trained us, and FOB Cochin puts a Gulf marine refit order one container hop from the water.
Boiling-waterproof glue line
A true 100% phenolic bond that holds through boil test, humidity and the wet life a marine panel actually leads.
Full hardwood core
Gap-free hardwood veneers — no soft fillers, no voids to hold water or collapse under a fixing.
Boatyards supplied by our group since 1986
Marine grades exported FOB Cochin to boatbuilders and joinery shops on five continents.
Questions buyers ask
Marine plywood, answered.
What is IS 710 marine plywood?
IS 710 is the Indian Standard for BWP (boiling-waterproof) marine plywood — a board bonded with a BWP-type adhesive conforming to IS 848, which resists water, steam and humidity without delaminating.
What is the difference between IS 710 and IS 303?
IS 710 is boiling-waterproof marine grade; IS 303 is moisture-resistant commercial grade. Different glue, different water resistance, different use. Full comparison →
What thickness should I use for a boat?
It depends on the part — thin for bending, thicker for decks and bulkheads. See the thickness guide →
Do you supply BS 1088 and what is the minimum order?
BS 1088 grade is available on request. Supply is by the container load (FCL), FOB Cochin Port.
Can I choose Okoume or Gurjan face on your marine plywood?
Yes — both face veneers are available on our IS 710 marine plywood. Okoume face is the traditional marine choice: pale, fine-grained, takes paint and varnish smoothly, and is noticeably lighter for the same panel. Gurjan/keruing face is the harder-wearing hardwood option, slightly heavier and better where the surface will see knocks before finishing. Either way the BWP/IS 710 phenolic glue line is the same — face veneer is a surface choice, not a waterproofing choice. Quote with your finish and use-case and we'll recommend.
Is marine plywood fully waterproof?
Marine plywood is IS 710 BWP, bonded with a boil-proof phenolic glue that withstands prolonged water and humidity. The panel is highly water-resistant; exposed edges and end-grain should still be sealed in wet installations.
What core does your marine plywood use?
A hardwood core — rubberwood or eucalyptus — with full BWP glue lines through every ply. That construction is what lets the panel hold up to moisture.
Where is marine plywood used, and how is it priced?
Bathrooms, kitchens, humid exteriors, and boat and furniture work exposed to moisture. We quote per specification rather than a shelf rate — send thickness, grade and volume for a written quote.
What thickness of marine plywood should I use for a boat?
It depends on the part - thinner for bending, thicker for decks and bulkheads. Cochin Wood supplies 4-25 mm.
Do you supply BS 1088 marine plywood and what is the minimum order?
BS 1088 grade is available on request. Supply is by the container load (FCL), FOB Cochin Port.
