And more importantly\u2026<br>which one should you use for your home furniture?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>First Things First \u2013 What Is an IS Code?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In India, plywood quality is certified by Bureau of Indian Standards (BIS).<br>They create \u201cIS Codes\u201d which are basically quality rulebooks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a plywood sheet follows the rules in the code, it can proudly carry the stamp:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>IS 303 or<\/li>\n\n\n\n<li>IS 710<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Think of the IS code like a health report of plywood.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a

class=\"wp-block-heading\"><strong>What IS 303 Actually Means<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">IS 303 is the standard for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Commercial plywood (MR grade)<\/li>\n\n\n\n<li>BWR plywood (Boiling Water Resistant)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is mainly meant for areas that don\u2019t stay wet all the time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a plywood has IS 303:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It means it has passed tests for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Basic moisture resistance<\/li>\n\n\n\n<li>Some boiling water exposure<\/li>\n\n\n\n<li>Moderate strength<\/li>\n\n\n\n<li>Resistance to normal household conditions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This is the plywood used in most indoor furniture in India.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Is IS 303 waterproof?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No.<br>It has some water resistance, especially BWR grade, but it is not made to survive long-term water contact.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What IS 710 Actually Means<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">IS 710 is the standard for:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Marine Grade Plywood (BWP)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BWP = Boiling Water Proof<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is the top-most grade of plywood for water resistance.<br>If a plywood has this stamp, it means it has survived tough tests like:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Being boiled in water for hours<\/li>\n\n\n\n<li>Long exposure to moisture<\/li>\n\n\n\n<li>Strong bonding tests<\/li>\n\n\n\n<li>Humidity and temperature stress<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This is designed for <strong>wet or risky areas<\/strong>, especially kitchens and bathrooms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Is IS 710 waterproof?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yes , fully waterproof.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.duroply.in\/blog\/wp-content\/uploads\/2026\/01\/Manish-Image-Sharing-1.jpg\"><img loading=\"lazy\"

class=\"wp-block-heading\"><strong>Strength &amp; Durability \u2013 Who Wins?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">IS 303 plywood<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Strong enough for normal furniture<\/li>\n\n\n\n<li>Safe for dry areas<\/li>\n\n\n\n<li>Good for wardrobes, beds, wall units<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">IS 710

water + steam<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>&nbsp;<\/strong><\/h2>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Where Should You Use IS 303?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most homeowners overspend on plywood because they think <em>everything should be waterproof<\/em>.<br>Not true.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IS 303 works wonderfully in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wardrobes<\/li>\n\n\n\n<li>TV units<\/li>\n\n\n\n<li>Book shelves<\/li>\n\n\n\n<li>Bedroom furniture<\/li>\n\n\n\n<li>Crockery

can safely save money here without compromising quality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tip:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always prefer BWR grade (IS 303) over MR grade.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Where Should You Use IS 710?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are places in your home where water, steam, or moisture is a daily guest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use IS 710 for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Kitchen under-sink cabinet<\/strong><\/li>\n\n\n\n<li>Cabinets near the stove<\/li>\n\n\n\n<li>Cabinets near the dishwasher<\/li>\n\n\n\n<li>Washbasin counters<\/li>\n\n\n\n<li>Bathroom vanity units<\/li>\n\n\n\n<li>Any furniture touching damp walls<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For the kitchen, especially:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>One small leak from the sink<\/li>\n\n\n\n<li>One day of pipe sweating<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Cost Difference \u2013 Is IS 710 Really Worth It?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, IS 710 costs more.<br>But think of it like an insurance policy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IS 303 price:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Medium<br>Good for 70% of the house<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IS 710 price:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Higher<br>Needed only for specific areas<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IS 303 = Everyday plywood for normal furniture<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reliable, affordable, safe for dry areas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IS 710 = Heavy-duty waterproof plywood<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The best choice for kitchens and bathrooms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If someone tells you:<br>\u201cUse IS 710 everywhere,\u201d<br>they\u2019re either selling or they don\u2019t know practical
