BIS Certification for Flexible Plywood Under IS 19952:2026 – Process, Specifications & Documents

Curved reception desks, round pillars, spiral arches and designer ceilings are now common in homes, offices and hotels. They are all made with flexible plywood, also called flexi-ply. Until recently, India had no dedicated standard for it. That has now changed. The Bureau of Indian Standards (BIS) has published IS 19952 : 2026, the first Indian Standard made only for flexible plywood. If you make, import or sell this product, you need to understand it now. Once it comes under a mandatory order, BIS certification for flexible plywood will be a must to sell in India.

This blog explains the new standard, the key flexible plywood specifications, the ISI mark process and what you should do next. It is written in simple words so that you can act without confusion.

What Is Flexible Plywood?

Flexible plywood is a bendable board made from thin veneers. Its layers and grain direction are arranged so that the sheet can curve smoothly without cracking.

It is commonly used for :

• Curved columns and pillars
• Round reception desks and counters
• Spiral arches and curved walls
• Designer false ceilings
• Curved furniture and modular interiors
• Shop displays and exhibition stands

Normal plywood is stiff. If you bend it too much, it snaps. Flexible plywood is built to bend without breaking.

What Is IS 19952 : 2026?

IS 19952 : 2026 is titled Flexible Plywood : Specification. It is issued by the Bureau of Indian Standards (BIS), under the Ministry of Consumer Affairs, Food and Public Distribution, Government of India.

Flexible Plywood Specifications Under IS 19952 : 2026

The standard sets requirements for both product quality and performance. Here are the main points.

IS 303 vs IS 19952 : 2026 : What Is the Difference?

This is why a flexi-ply board cannot be judged by old plywood tests. It needs its own standard.

Please note : Until a QCO is notified, certification for this product may be voluntary. Once it is notified, it becomes compulsory, and a transition period is usually given. Businesses that prepare early will not face a rush.

ISI Mark for Plywood : What Does It Give You?

The ISI mark certificaftion for plywood tells buyers that the product meets the Indian Standard and that the factory is checked by BIS.

Benefits for manufacturers :

1. Legal right to sell once the QCO applies
2. Higher trust from architects, interior designers and contractors
3. Better chances with large projects and tenders
4. A clear edge over uncertified grey-market products
5. Lower risk of complaints over cracking and peeling
6. Stronger brand value in a growing market

Large plywood brands already work with BIS on standards. For example, in a BIS committee meeting (CED 20) held on 20 July 2020, Greenply Industries Limited asked BIS to review the plywood standard so that it matches modern materials. This shows that standards change with the market, and that companies that follow them early stay ahead.

BIS ISI Mark Certification for Plywood : Who Needs It?

1. Domestic manufacturers of plywood and plywood-based boards
2. Plywood mills in clusters such as Yamunanagar, Perumbavoor and others
3. Importers and foreign mills that send plywood to India
4. Traders and brands who sell under their own label (the license holder must be the manufacturer, so label arrangements need care)

For flexible plywood, two groups need to act :

1. Domestic manufacturers must upgrade their testing setup and apply for an ISI license.
2. Importers and foreign mills must obtain certification under the Foreign Manufacturers Certification Scheme (FMCS) before shipping flexible plywood to India, once the product is notified.

BIS Certification for Flexible Plywood: Step-by-Step Process

The certification route is Scheme-I (ISI Mark) under IS 19952 : 2026.

Step 1 : Set Up an In-House Lab

You need your own testing facility. It should be able to run :

1. Bend radius tests
2. Glue shear tests
3. Moisture content checks
4. Size and thickness checks

Equipment must be calibrated, and trained staff must run the tests.

Step 2 : File the Application Online

Apply on the BIS Manakonline portal with Form V. You will submit :

1. Plant layout
2. Machinery details
3. Raw material details
4. Test records
5. Authorized person details

Take care here. Missing or wrong details are a common cause of delay.

Step 3 : Factory Audit and Inspection

A BIS auditor visits your plant. The auditor checks :

1. Production controls
2. Raw material handling
3. Process records
4. Testing equipment and how tests are done

The auditor may also witness your in-house tests.

Step 4 : Independent Lab Testing

Samples are drawn during the inspection, sealed and sent to a BIS-approved third-party lab. The lab checks them against IS 19952 : 2026.

Step 5 : Grant of License

If the audit and the lab tests are satisfactory, BIS grants the license. You receive a CM/L number. This allows you to print the ISI mark on each sheet.

Documents You Should Keep Ready

• Business registration and ownership papers
• Factory address proof and plant layout
• Machinery and equipment list
• Raw material and supplier details (veneer, adhesive, resin)
• In-house lab details and calibration records
• Test records for bend radius, glue shear and moisture
• Quality control manual
• Authorized signatory and contact person details

For foreign mills under FMCS, the papers also include the mill's details, an authorized Indian representative, and the required local approvals.

How Long Does It Take?

Timelines depend on how ready your factory is and how quickly BIS schedules the audit and lab results.

If everything is correct, the process runs smoothly. Most delays come from gaps in lab setup, missing records or wrong details in Form V.

Common Mistakes to Avoid

1. Waiting for the QCO and starting late
2. Using old plywood test methods for flexible boards
3. Setting up a lab without bend radius testing equipment
4. Using glue that fails after repeated bending
5. Ignoring formaldehyde limits
6. Incomplete or wrong details in Form V
7. No trained staff for in-house testing
8. Selling under a brand name without clarity on who holds the license

These mistakes can delay your license by weeks or even months, and can block your sales.

Real-World Example : Why Early Preparation Pays Off

When plywood for general purposes (IS 303) came under strict control, many mills in plywood clusters had to upgrade machines, labs and records in a short time. Mills that had already built testing systems moved faster, while others faced stock holding and delays at the start.

Flexible plywood is now at the same point. The standard is published, the product has a clear test method, and the QCO is expected to follow. Mills in clusters such as Yamunanagar, Perumbavoor and Kandla, along with interior board importers and architectural panel suppliers, can use this window to get certified first.
