BIS Certification Consultancy for Plywood for General Purposes | IS 303:1989

Introduction

Plywood for general purposes is one of the most widely used wood-based panel products in construction, furniture, interior work, doors, partitions, cabinetry and other applications. Consistent bonding, strength, dimensions, moisture performance, surface quality and formaldehyde control are important for ensuring reliable plywood performance.

For many years, manufacturers referred to IS 303:1989 – Plywood for General Purposes for BIS certification. However, the standard has subsequently been revised. BIS published IS 303:2024 – Plywood for General Purposes – Specification (Fourth Revision), and its implementation guidelines stated that IS 303:1989 would stand withdrawn after 14 February 2025.

The current BIS Product Manual is PM/IS 303/4/May 2025, based on IS 303:2024 with Amendment No. 1. Therefore, manufacturers starting a new certification process today should generally assess their product against the current IS 303:2024 requirements rather than relying only on the old 1989 requirements.

The product continues to be covered under the Plywood and Wooden Flush Door Shutters (Quality Control) Order framework. The 2024 QCO requires covered products to conform to the applicable Indian Standard and bear the Standard Mark under a BIS licence as per Scheme-I, subject to specified exemptions.

Qualitance India provides complete BIS Certification consultancy for plywood manufacturers, including standard applicability assessment, documentation, product testing coordination, grouping guidance, factory inspection preparation, BIS application support, licence processing and post-licence compliance.

What is BIS Certification for Plywood?

BIS Certification is a conformity assessment mechanism under which a manufacturer demonstrates that its product complies with the applicable Indian Standard and related BIS requirements.

For plywood covered by the applicable compulsory certification framework, the manufacturer must follow the relevant standard, testing requirements, quality-control arrangements and certification procedure before using the BIS Standard Mark on licensed production.

The current BIS Scheme-I listing identifies IS 303:1989 – Plywood for General Purposes in the historical listing alongside the applicable Plywood and Wooden Flush Door Shutters Quality Control Orders.

Because the standard has since been revised, the current certification route must be assessed against IS 303:2024 and its applicable amendment.

Important Update: IS 303:1989 Revised to IS 303:2024

This is an important point for plywood manufacturers.

BIS published IS 303:2024 – Plywood for General Purposes – Specification (Fourth Revision). BIS implementation guidelines issued in July 2024 stated:

• IS 303:1989 was revised as IS 303:2024.
• The last date for implementation of the revised standard was 14 February 2025.
• After the implementation date, the old standard was to stand withdrawn.

BIS subsequently published Amendment No. 1 to IS 303:2024. The implementation guideline dated 26 May 2025 stated that the amendment had to be implemented by 17 September 2025.

The latest BIS Product Manual located for this product is PM/IS 303/4/May 2025, covering IS 303:2024 with Amendment No. 1.

Therefore, businesses searching for “BIS Certification for Plywood as per IS 303:1989” should understand that the current certification requirements have moved to the revised standard.

What is Plywood for General Purposes?

Plywood is an engineered wood panel produced by bonding layers of wood veneer together, normally with adjacent veneer grains arranged in different directions.

For general-purpose plywood, product performance depends on:

• Veneer quality
• Veneer thickness
• Grain direction
• Adhesive quality
• Bonding
• Core construction
• Surface quality
• Moisture content
• Water resistance
• Mechanical strength
• Dimensional accuracy
• Formaldehyde performance

The current IS 303:2024 framework expands the classification structure compared with the older standard.

Product Classification Under Current IS 303:2024

The current BIS Product Manual classifies plywood using several parameters.

Grade

The current standard covers:

• MR – Moisture Resistant
• BWR – Boiling Water Resistant
• BWP – Boiling Water Proof

Bending Class

The revised standard, including Amendment No. 1, uses five bending classes:

• F10
• F20
• F30
• F40
• F50

Type Based on Appearance

The current Product Manual identifies:

• AA
• AB
• AC
• BB
• BC
• CC

Thickness

Specified thicknesses include:

3, 4, 5, 6, 9, 12, 15, 19, 22 and 25 mm

Other thicknesses may be agreed between manufacturer and purchaser, subject to the applicable standard provisions. The manufacturer is required to declare the thickness range intended to be covered.

Formaldehyde Class

The current framework identifies:

• E1
• E2

Steady-State Formaldehyde Emission

The Product Manual treats the steady-state formaldehyde emission test as an optional test, and the scope can indicate whether the certification includes this test.

BIS Grouping Guidelines for Plywood

Grouping is one of the most important parts of the BIS application because plywood manufacturers often produce many combinations of grades, thicknesses, appearance types and bending classes.

The current Product Manual provides grouping based on:

• Grade
• Bending Class
• Appearance type
• Thickness
• Formaldehyde class
• Optional steady-state formaldehyde emission test

Grouping by Bending Class

Plywood of each bending class must be tested to cover that particular bending class in the licence scope.

The manufacturer should ensure that samples cover the grades and formaldehyde classes intended for inclusion in the licence.

Grouping by Thickness

The Product Manual allows plywood of any thickness to represent the declared thickness range, provided the manufacturer has the necessary manufacturing and testing infrastructure and the required range is appropriately demonstrated through sampling.

Grouping by Appearance

The highest appearance type tested can cover lower appearance types.

For example, testing AA can cover lower types such as:

• AB
• AC
• BB
• BC
• CC

Similarly, testing BB can cover:

• BC
• CC

Formaldehyde Emission Grouping

One sample is required for the optional steady-state formaldehyde emission test to include that test in the licence scope.

The manufacturer must declare the varieties intended to be covered, and the final licence scope can be restricted according to manufacturing and testing capabilities.

BIS Sample Size for Plywood

The current Product Manual specifies:

Sample Quantity: 1 sheet of plywood.

Correct sample selection is essential because one sheet may be used to establish a significant portion of the proposed licence scope under the applicable grouping provisions.

Raw Material Requirements

The current May 2025 Product Manual does not specify a separate raw-material sample quantity in its sampling table and notes that this section addresses raw-material requirements where specified in the Indian Standard.

The older IS 303:1989 product manual identified:

• Adhesive – IS 848
• Extenders – IS 1508

For current certification, the manufacturer should follow the material requirements of IS 303:2024 and its amendment, rather than relying solely on the historical 1989 material provisions.

Manufacturing Process for Plywood

A typical plywood manufacturing process may include:

Log Selection → Timber Conversion → Veneer Peeling/Slicing → Veneer Clipping → Drying → Grading → Glue Preparation → Glue Application → Lay-Up → Pre-Pressing → Hot Pressing → Trimming → Sanding → Surface Inspection → Dimensional Inspection → Testing → Marking → Packing

The exact process can vary according to the manufacturer’s equipment, timber species, veneer construction, adhesive system and product specification.

Important Manufacturing Controls

A plywood manufacturer should maintain control over:

• Timber quality
• Veneer thickness
• Veneer moisture
• Grain direction
• Core construction
• Glue mixing
• Glue spread
• Pressing conditions
• Temperature and pressure
• Pressing time
• Panel thickness
• Edge quality
• Surface quality
• Final conditioning
• Product testing

Proper production controls help maintain consistent plywood quality.

Main BIS Tests for Plywood

The testing requirements depend on the applicable grade, type, bending class, formaldehyde class and other declared characteristics.

Important testing areas under the current framework include the following.

1. Classification by Appearance

Surface appearance is assessed according to the permitted categories and defects.

The current LIMS test scopes identify appearance classification and defect categories including:

• Blisters
• Checks
• Discolouration
• Dote
• Insect holes
• Joints
• Dead knots
• Dead pin knots
• Live pin knots
• Tight knots
• Patches
• Splits
• Swirl

2. Veneer Thickness

Veneer thickness is checked against the requirements of the applicable standard.

3. Grain Direction

Grain direction is controlled to ensure the correct construction and orientation of veneers.

4. Gaps in Cores and Cross-Bands

The panel is checked for gaps in internal veneer construction.

5. Splits and Overlaps

Construction defects such as splits and overlaps are controlled according to the standard.

6. Dimensions

Important dimensional checks include:

• Length
• Width
• Thickness
• Squareness
• Edge straightness

7. Moisture Content

Moisture content is an important property affecting panel performance and dimensional stability.

8. Glue Adhesion / Water Resistance

Glue adhesion and water resistance are key requirements, particularly for MR, BWR and BWP products.

9. Mycological Test

Applicable plywood grades may require mycological testing related to glue adhesion and biological resistance.

The current LIMS entries identify mycological testing as part of the test scope.

10. Static Bending Strength

The revised IS 303 framework places significant importance on mechanical strength.

Bending strength is linked to the five bending classes:

• F10
• F20
• F30
• F40
• F50

The amendment modified the MOE and MOR requirements based on these bending classes.

Tests can include:

• Modulus of Elasticity
• Modulus of Rupture
• Along face grain
• Across face grain
• Average values
• Minimum individual values

11. Formaldehyde Content

Formaldehyde content testing is included in the current testing framework for the declared formaldehyde classes.

12. Steady-State Formaldehyde Emission

This is an optional test under the current Product Manual.
