Step-by-Step Process for BIS Certification of Chipboard Screws as per IS 18508

 In the world of construction, furniture manufacturing, and woodwork, chipboard screws are indispensable. These screws, known for their ability to firmly anchor into particleboard and similar materials, must meet precise quality and safety standards to ensure durability and performance. To enforce uniformity and safety across the industry, the Bureau of Indian Standards (BIS) mandates that chipboard screws comply with IS 18508, the Indian Standard that outlines their specifications.

With the implementation of mandatory BIS certification for chipboard screws, manufacturers and importers now need to undergo a formal certification process to legally market or sell their products in India. In this blog, we’ll walk you through the step-by-step process for obtaining BIS Certification for chipboard screws under IS 18508, discuss its importance, and explain how to ensure smooth compliance.

What is IS 18508?

IS 18508: Chipboard Screws – Specification is an Indian Standard that defines the design, mechanical properties, materials, and testing methods for chipboard screws. These screws are typically used for joining chipboards, MDF, plywood, and other types of engineered wood.

The standard covers parameters like:

  • Screw dimensions

  • Head styles

  • Thread types

  • Drive types

  • Mechanical strength

  • Corrosion resistance

By adhering to IS 18508, manufacturers ensure that their screws meet performance benchmarks, reducing the risk of failure and increasing customer satisfaction.

Why is BIS Certification for Chipboard Screws Important?

With increasing demand for quality fasteners in India’s infrastructure and furniture sectors, the government has made BIS certification mandatory to:

  • Eliminate substandard or counterfeit products

  • Protect consumer and industrial safety

  • Promote the use of standardized, high-quality products

  • Support India's Make-in-India initiative

Without BIS Certification, manufacturers and importers are prohibited from selling chipboard screws in the Indian market. Compliance is not optional—it’s legally required.

Who Needs BIS Certification under IS 18508?

  • Domestic Manufacturers: All Indian manufacturers of chipboard screws must obtain certification to sell within India.

  • Foreign Manufacturers: Companies exporting chipboard screws to India must get certified under the Foreign Manufacturers Certification Scheme (FMCS).

  • Importers and Traders: Must ensure that their sourced screws are certified under IS 18508.

Step-by-Step Process for BIS Certification for Chipboard Screws (IS 18508)

Here’s a detailed guide to help you understand the certification process:

Step 1: Understand the Applicable Scheme

Depending on where the manufacturing unit is located, choose the appropriate BIS scheme:

  • Simplified Procedure for Domestic Manufacturers (SPD)

  • Foreign Manufacturers Certification Scheme (FMCS)

Each has its own guidelines, documentation, and timelines, although the evaluation criteria remain consistent.

Step 2: Prepare Required Documents

Before applying, gather the necessary documents, which typically include:

  • Factory license and incorporation certificate

  • Manufacturing process flow diagram

  • Quality control and testing equipment list

  • Test reports (if any)

  • Layout of the factory

  • Details of raw materials and suppliers

  • Authorized signatory details

  • Product drawing and specifications

Ensure your facility is ready with proper quality assurance and in-house testing setups, as these will be inspected later.

Step 3: Submit the Online Application

Visit the official BIS portal and:

  • Choose the product category: Chipboard Screws (IS 18508)

  • Fill out Form VI (for Indian manufacturers) or the FMCS form (for foreign units)

  • Pay the application fees

  • Upload all the supporting documents

Double-check for accuracy, as errors or omissions can cause delays.

Step 4: Product Sample Testing

Once your application is accepted:

  • BIS will ask you to submit samples of your chipboard screws.

  • These samples must be sent to a BIS-approved laboratory for testing.

  • The lab will test the product against all the criteria outlined in IS 18508, including:

    • Tensile strength

    • Torque requirements

    • Dimensional accuracy

    • Corrosion resistance

The testing phase is crucial, as failure here means restarting the process.

Step 5: Factory Inspection by BIS Officials

A BIS officer will visit your manufacturing facility to:

  • Inspect the production line

  • Verify the quality control process

  • Ensure the availability and calibration of test equipment

  • Review raw material sourcing

  • Examine staff training and SOPs

For foreign applicants, this inspection is part of the FMCS and includes additional logistics like visa coordination and translator services (if needed).

Step 6: Evaluation of Test Reports and Audit Findings

BIS will now:

  • Review your lab test results

  • Assess the on-site inspection report

  • Confirm if all standards are met

If any shortcomings are found, BIS may:

  • Ask for clarification

  • Suggest corrective actions

  • Reject the application (in rare cases)

Step 7: Grant of BIS License

Upon successful evaluation, BIS grants a certification license. You are now authorized to:

  • Use the ISI mark on your chipboard screw packaging

  • Commercially distribute the product in India

  • Enjoy the recognition of being a certified manufacturer

Step 8: Post-Certification Obligations

BIS certification is not a one-time process. You must:

  • Submit to regular surveillance audits

  • Maintain your quality control and production standards

  • Renew your license as required (typically every 1–2 years)

  • Keep test records and documentation ready for review

Failing to comply can lead to license suspension or revocation.

Timeline for Certification

The average timeline for completing the BIS certification process for chipboard screws is:

  • Domestic applicants: 3–4 months

  • Foreign applicants (FMCS): 6–8 months (due to travel and documentation)

Delays can occur if:

  • Testing fails

  • Documents are missing

  • Factory audit reveals non-compliance

Hence, early planning is crucial.

Role of a BIS Consultant

A professional BIS Consultant can:

  • Help with technical documentation

  • Coordinate lab testing and application submission

  • Prepare you for the factory audit

  • Reduce rejection risks

  • Ensure faster approval

Especially for foreign manufacturers, working with a BIS Consultant in India makes the process seamless and stress-free.

Conclusion

As BIS certification for chipboard screws under IS 18508 becomes mandatory, manufacturers and importers must act quickly to align with the standard. The certification doesn’t just ensure legal compliance—it demonstrates your commitment to quality, safety, and customer trust.

By following the steps outlined above and partnering with experienced consultants, your business can achieve certification smoothly and efficiently. In a market that values reliability and durability, BIS Certification is not a cost—it’s an investment in your brand’s future
