Two interior estimates may name the same plywood brand and still describe different furniture. To compare prices fairly, ask for the exact product, its grade and standard, the bare-core thickness, and where each board will be used.
A brand is a starting point, not a specification
CenturyPly and Greenply each sell several BWP ranges. For example, CenturyPly lists Sainik 710, Classic Marine and Club Prime; Greenply lists Absolute BWP, Gold and Club 700. These are examples from broader ranges, not the only three BWP choices from either company, and not a ranking or endorsement. Ask which exact product and grade is in the quotation and where it will be installed.
Read grade and Indian Standard together
MR means moisture resistant; BWP means boiling water proof under specified tests. The revised IS 303:2024 includes MR, BWR and BWP grades. IS 710:2024 is the separate marine plywood specification. Therefore, “IS 303” alone does not tell you the grade, and a product name containing “710” is not proof that it carries IS 710 certification. Check the manufacturer’s current declaration for the exact range.
For instance, CenturyPly’s current Sainik 710 page declares IS 303 BWP, while its Club Prime page declares IS 710. Greenply’s Absolute BWP page lists BWP and IS 303, and its Gold brochure declares IS 710. These examples show why the full product name, grade and standard belong together in the estimate.
Where should BWP or MR be used?
BWP is a sensible starting specification for sink cabinets and bathroom vanities exposed to possible water. A suitable MR product can be appropriate for genuinely dry wardrobes or TV units with limited moisture exposure. A damp wall, plumbing risk or unusual site condition changes that assessment. BWP also needs sound edge sealing, pipe cut-out detailing and prompt leak repairs; no board makes a poorly detailed cabinet leak-proof.
What does 16 mm versus 18 mm MR tell you?
Both can be genuine nominal plywood sizes. For comparable panels, greater thickness generally improves bending stiffness, but shelf span, load, supports, joints and hardware also matter. A 16 mm sheet can be right for an appropriate design; 18 or 19 mm may be chosen where additional stiffness is needed. Thickness does not change MR into BWP.
Clarify whether the quote means bare plywood core or finished panel. A 16 mm core with 1 mm laminate on each face can be around 18 mm before adhesive and tolerances. That is still a 16 mm plywood core. Check the exact product’s offered thickness and tolerances, then ask where that thickness is used.
Five details to get in writing
- Exact manufacturer and product range.
- Declared grade and Indian Standard.
- Nominal bare-core thickness, with component-wise use.
- Finishes, hardware, installation, exclusions and GST treatment.
- How supplied sheets and any substitution will be verified and approved.
Before boards are covered, photograph product markings and match the invoices and delivery records to the approved material list. The BIS licence can be checked through BIS Care where a Standard Mark and licence are claimed. A lower quote may be entirely legitimate; the question is whether its specification matches the other one.
Video narration in brief
“CenturyPly” or “Greenply” is not enough to compare two estimates. Match the product range, grade and standard, bare-core thickness and intended component. Then compare the rest of the scope and price.
Sources and scope
Reviewed against the BIS IS 303 product manual, BIS IS 710:2024 information, and current CenturyPly and Greenply product ranges. Product claims can change; check the latest manufacturer sheet and the actual material supplied. This guide does not recommend a single grade for every room or quote an installed rate.
Ask both firms for the same written material and component schedule before judging the price gap.
