Resin-treated laminates made from compressed wood, also known as Compregs, which are relatively new classes of engineered wood with excellent performance attributes, which have not only found market acceptance but are widely being used in various industries. These laminates involve the use of wood veneers or fibers of aspects bonded together with synthetic resins at high temperature and pressure and turns out to also be very strong and has a capability of resisting moisture and warping. In India, Quality Control Orders (QCOs) have been framed by the Bureau of Indian Standards (BIS) for compregs to conform to standard norms of safety and quality. The setting up of this kind of regulatory framework is important for the manufacturer's drive to offer quality goods to the consumers as well as protect end users. Moreover, in cases where composite materials are used as a solution for sustainable and high-performance demands as a material, it requires careful knowledge about the compregs manufacturing process, performance requirements, testing, and certification procedure.
In this blog, more information about the applications of resin-treated compressed wood laminates in the market, the reason behind BIS certification, and the compliance process involved in getting the same. Regardless of whether you are a manufacturer, a consumer, or an industry expert, this information-packed guide will prove helpful when it comes to understanding compregs.
BIS Registration Sample
Compregs are among the various wood products fabricated from layers of wood veneers or strands of fibers that have been bonded together with synthetic resins. This process improves the physical characteristics of the wood, the most notable being increased density making it more decay resistant, moisture resistant, and for use in a variety of uses. Compregs are especially prized for their high strength-to-weight ratio, low tendency to warp, and the fact that they can be easily integrated into a range of designs.
Manufacture of compregs involves putting these layers through high pressure and temperature in order to both cure the resin and ensure compregs density and strength. It is important for use in situations that may otherwise be vulnerable to rot, thanks to water or any other natural conditions or pressure from mechanical forces that are common in the industry.
The manufacturing process of resin-treated compressed wood laminates consists of several key steps:
This method yields a material that exhibits superior mechanical properties than traditional wood products.
It is imperative that Compregs exhibit specific performance characteristics to be applied effectively in applications. Key performance indicators include:
Many of the testing methods applied to compregs are as per tests prescribed by some organizations of testing such as the Bureau of Indian Standards (BIS). Common testing methods include:
This standard provides procedures for evaluating the physical characteristics of wood composites including compregs.
This standard outlines procedures for determining the moisture content, and the floors’ ability to resist changes in dimension.
This standard describes procedures for fire-resistant testing of building elements, products, and structures.
These standardized tests make sure that compregs meet necessary legal standards and are dependable in their sold uses.
To conduct testing on the Resin treated compressed wood laminates (compregs) – For general purposes effectively, laboratories must adhere to specific requirements:
Labeling and markings are fundamental requirements of BIS standards regarding specifications for Resin-treated compressed wood laminates (compregs)– For general purposes. Each product must include:
The following are the given documents for BIS Certification:
| General Documents | Technical Documents |
|---|---|
| Business License | Plant Layout |
| Trademark License | List of Manufacturing Equipment |
| Application Form | Manufacturing Process Flow Chart |
| Authorization Letter | Product Literature |
| Laboratory Test Reports | List of testing equipment and machinery |
| MSME certificate | Product’s technical Specification |
| List of calibration certificate |
The BIS certification process for Resin treated compressed wood laminates (compregs) – For general purposes involves several steps:
Applications are filled including relevant documents that outline the production processes of the manufacturers.
A BIS officer pays a visit to the manufacturing company in order to assess the levels of compliance with set regulations.
The samples from the production batches are analyzed at the BIS-accredited laboratories.
As a result of the evaluation of these facilities and products, BIS grants permission to the manufacturers to use the ISI mark on their products.
To sustain the standards practice, normal assertions are carried out.
This is a process that the manufacturers need to understand so that they can get an efficient certification process.
Importance of BIS Certification
BIS certification is crucial for several reasons:
Conclusion
Specifically, compressed wood laminates with resin treatment are important to many industries because they have physical-mechanical properties superior to most wood products. Realizing their production process, performance characteristics, testing procedures, laboratory requirements, labeling standards, documentation needed for certification, certification procedures, and general relevance highlights their role in quality control and consumer protection in India.
While manufacturers seeking BIS certification for products under QCOs are enhancing the success of their businesses, they are also enhancing consumer protection as well as the stability and integrity of markets.
At Professional Utilities, we leverage our industry knowledge and expertise to help businesses navigate complex regulations, minimize risks, and optimize operations for maximum efficiency and profitability.
Compregs are widely employed in furniture manufacturing, construction materials, flooring choices, and miscellaneous other uses because of their stability in breaking down from moisture.
Depending on the completeness of documentation or inspections to be carried out, it can take as little as a few weeks or as long as a few months.
Some small-scale manufacturers may be allowed to supply QCO-free products under special circumstances though they depend on the type of product that is being supplied.

They've been very helpful in our registration with ICEGATE. It was a small thing with a small amount paid which somehow escalated to a very painful procedure. Never did they say "You've only paid so much. It's too much effort for us.".
Very pleased with their service. Prompt, professional and great communication. Definitely recommend. Special mention for Ms. Razia - she handled our case.
Professional Utilities is fully professional in their work, Rates are too low and genuine. Services and satisfaction are high so I highly recommended Professional Utilities.
They are one of the most genuine and reasonable people. I applied for lmpc certificate through them and they charged me a very nominal amount as compared to what other firms asked .
