Questions Every Homeowner Should Ask Their Plywood Dealer

Author Name: Greenply Industries

Your carpenter has given you a quote, and now you are at the counter of the plywood dealer. The dealer says 'good quality, same as branded', and you have no easy way to test that. Swollen sink bases and sagging wardrobe shelves often begin with a vague answer at this moment, not with a bad carpenter.

Ten questions follow, grouped by what they settle: grade, the sheet itself, warranty and delivery. Each has a reason to ask, what a good answer sounds like and what should make you pause. Two other Greenply posts, linked below, cover the physical checks on the sheet.

Before you visit: know your zones

A zone is a place in your home plus what it faces, such as water, heat, load, children or closed air, and your zones decide the grade of plywood you need. A dealer can only advise well when you say where each board will go.

Write down each piece your carpenter will build and match it to the table below. Take the list to the shop. It turns 'what is good?' into 'what is right for a sink base?', and dealers answer the second question far more honestly.

The grades in the table are the ones your dealer should name without hunting for them. If a grade is not on your list, ask why it is being suggested for that piece.

Questions to ask your plywood dealer about grade, the sheet and warranty

The first eight questions settle what the board is, how thick it is and what the brand will stand behind. Ask them in this order, because each answer tells you how seriously to take the next one.

1. Which grade is this, and which IS standard does it follow?

Why ask: Grade is the one fact that separates a board for a dry shelf from a board for a sink base. A brand name alone does not tell you the grade.
A good answer sounds like: 'This is BWR grade under IS 303. For under the sink, let me show you the IS 710 marine sheet.' The dealer names the grade and the standard without hunting for them.
A red flag is: 'Waterproof' with no grade, or 'commercial' or 'marine type' with no IS number. MR and BWR grades resist water but are not made for standing water.

2. Is this the right grade for my kitchen, bathroom or wardrobe?

Why ask: Marine grade in a dry bookshelf wastes money. MR grade under a sink swells at the first slow leak.
A good answer sounds like: The dealer asks where the board goes, then splits your list into one grade for wet zones and another for dry zones. This post on plywood for kitchen cabinets shows that split.
A red flag is: One sheet recommended for every room. Another is the cheapest grade for the sink base because 'laminate will cover it'.

3. Where on the sheet is the ISI mark and standard number?

Why ask: The marking lets you match the bill to the board. A real grade claim can be pointed to on the sheet.
A good answer sounds like: The dealer lifts a sheet and shows the brand, grade and IS number printed on it.
A red flag is: 'The mark is on the carton, not the sheet', or a print that is smudged or missing. For the full physical check, read how to identify good quality plywood.

4. What is the actual thickness, and is it even across the sheet?

Why ask: Shelves sag and carcass sides sit unevenly when a stated 19 mm board is thinner at one end. Hinges and screws also grip less in a thin board.
A good answer sounds like: '19 mm, and the sheets are calibrated.' The dealer lets your carpenter measure with a calliper.
A red flag is: Any hesitation to be measured. Another is 'it is the same thing' when the sheet shown is visibly thinner than the one you asked for.

5. What is the core, and how many layers does it have?

Why ask: Layer count and core wood affect screw holding and sagging in wardrobes, beds and study tables.
A good answer sounds like: A specific reply, such as the number of plies and the core wood, which matches the brand's product page.
A red flag is: 'Full hardwood' with no detail. Gaps and patches visible on the edge are another warning.

6. What is the formaldehyde emission class of this board?

Why ask: Wardrobes and kids room furniture are closed spaces, so emissions linger there. Low-emission boards help keep indoor air cleaner.
A good answer sounds like: 'E0 class, with CARB certification.' E0 is the lower-emission class of the E0 and E1 pair.
A red flag is: 'No smell means safe', or no knowledge of the emission class at all.

7. What does the warranty cover, and who honours it?

Why ask: A warranty helps only if you know what counts as a manufacturing defect and whom to call. Damage from a household leak is usually outside it.
A good answer sounds like: The dealer reads the terms from the brand's page or card and says whether the brand or the shop handles a claim.
A red flag is: A spoken 'lifetime guarantee' that appears nowhere in writing, or one the brand's own page does not state.

8. Will the bill name the brand, grade, thickness and quantity?

Why ask: The bill is your proof of what you bought. It protects you if the sheets delivered differ from the sheets shown.
A good answer sounds like: A GST bill that lists brand, product, thickness and number of sheets, issued without fuss.
A red flag is: A handwritten slip that says only 'plywood 19 mm', or a cash discount that skips the bill.

Questions about delivery and storage

Delivery questions protect the board after you have chosen it, because good plywood can still be spoiled between the shop and the carpenter's workshop. Ask these two before you pay, and keep the answers in the quote.

9. Will the sheets arrive in original packing?: Ask for sheets strapped from the same batch you were shown. A good answer is a clear yes, with the brand and grade visible on the stack when it lands.
Check on arrival: Count the sheets against the bill and look at the marking on two or three of them before the delivery person leaves. Note any mismatch on the bill.
10. How should I store the sheets?: Boards soak up monsoon humidity when they stand on damp floors, which later shows as warping or swollen edges. A good dealer says keep them flat, off the floor, in a dry room.
Ask about timing: Ask your carpenter to start soon after delivery, so sheets are not left in a humid corner for weeks. If work is delayed, ask the dealer to hold the order instead.

Red flags at the counter

Three things should slow you down at any counter: pressure, vague answers and a refusal to put things in writing. A dealer who trusts the product shows the mark, names the grade and gives you a bill. For more on what to look for on the sheet, read warning signs of low-quality plywood.

Rush to decide: 'Rates go up tomorrow' is a push, not a reason. Ask for a written quote and compare it at another shop.
Grade-free answers: 'Best quality' and 'export quality' are not grades. Ask for the IS number and the grade name.
Sample and order do not match: Ask that the delivery match what you were shown, and have the brand written on the bill.
Discount for skipping the bill: It also removes your proof for any warranty claim. Take the bill, even if the rate looks slightly lower without it.

Greenply options to name at the counter

Once you know your zones, these are Greenply boards worth naming at the counter. At Greenply, each product page lists the grade and standard, so you can check the dealer's words against the page.

Greenply 710 Marine Plywood: IS 710 certified and made with BWP-grade resole resin. Its page recommends it for internal uses such as kitchens, bathrooms and cabinets, with a 25 years warranty on manufacturing defects.
Greenply Platinum Plywood: IS 5509 certified fire retardant plywood, preservative treated as per IS 5539, with a 30 years warranty on manufacturing defects. It suits kitchens and kids rooms.
Greenply Club 700 Plywood: Structural grade, IS 10701 certified, with 15 layers. It fits wardrobes, beds and study tables.

Look Beyond the Grade: Ask About TermiVax Protection

Choosing the right plywood grade is important, but long-term protection matters too. Termites, borers, and fungi can affect wooden furniture over time, making it worth asking your dealer about the protective technology used in the plywood.

Greenply’s TermiVax technology uses proprietary nanotechnology to protect plywood against termites, borers, and fungi. When comparing options, ask about the Greenply products featuring TermiVax technology and the protection they offer.

Frequently Asked Questions

How do I find a trustworthy plywood dealer?

A trustworthy dealer names the grade and IS standard without hesitation and shows the marking on the sheet. The dealer also issues a proper bill with brand, thickness and quantity. Ask your carpenter and neighbours about recent purchases, and compare answers at two shops before you place an order.

What is the difference between MR, BWR and BWP plywood?

MR, BWR and BWP are grades with rising water performance. MR is moisture resistant and suits dry rooms. BWR is boiling water resistant under IS 303. BWP follows IS 710 for marine use. Choose BWP for sink bases and splash zones, and MR only for dry rooms.

What should a plywood bill include?

A plywood bill should list the brand, product name, grade, thickness and number of sheets. It should also carry the dealer's GST details and the date. This record backs any warranty claim and lets you confirm that the sheets delivered match what you ordered.

How should I store plywood at home before the carpenter starts?

Store plywood flat, off the floor, in a dry room with good airflow. Rest it on level battens and keep it away from damp walls and bathrooms. Sheets left leaning in humid corners pick up moisture, which can show later as warping at the edges.

Which plywood is best for furniture?

The best plywood for furniture depends on the piece and the room. Use BWP-grade marine plywood for sink bases and wet zones, BWR or fire retardant grades for kitchens, and MR grade for dry-room shelves and wardrobes. Match the grade to the zone instead of buying one sheet for the whole house.
