Introduction
In India’s furniture and hardware industry, even the smallest component—like a hinge—plays a major role in safety and longevity. A few years ago, a hardware manufacturer from Gujarat faced repeated product rejections from government tenders due to missing BIS approval. The reason? Their Steel Back Flap Hinges didn’t comply with IS 3843:1995 standards.
After obtaining BIS Certification, the brand saw a remarkable turnaround—approval for major contracts, improved credibility, and higher customer trust. This shows why BIS Certification for Steel Back Flap Hinges is not just a legal formality but a business necessity.
What is IS 3843:1995?
IS 3843:1995 is the Indian Standard Specification that defines the quality, design, materials, and performance requirements for Continuous (Piano) Hinges and Back Flap Hinges made of steel.
It ensures that the hinges:
- Provide smooth operation without distortion.
- Resist corrosion and wear during frequent use.
- Meet minimum strength and durability standards.
The standard applies to hinges used in doors, furniture, cabinets, and industrial applications where stability and longevity are critical.
Why BIS Certification for Steel Back Flap Hinges Matters
Obtaining Bureau of Indian Standards Certification assures both manufacturers and buyers that the hinges conform to national quality and safety standards.
Key Reasons It Matters:
- Market Legality: BIS Certification is mandatory for select hardware items under the Steel Products (Quality Control) Order.
- Quality Trust: The ISI mark assures customers about performance consistency.
- Tender Eligibility: Required for participation in government procurement projects.
- Export Approval: Facilitates easier acceptance in international markets.
This certification transforms a manufacturer’s reputation from “local” to “standard-compliant and globally trusted.”
Understanding the ISI Mark for Steel Back Flap Hinges
The ISI Mark on a hinge confirms that it has been tested, verified, and approved as per IS 3843:1995.
When a product bears this mark, it means:
- The product has passed mechanical performance tests and corrosion resistance evaluations.
- The manufacturer maintains a BIS-approved quality control system.
- BIS conducts regular factory inspections and random product sampling to ensure ongoing compliance.
Essentially, the ISI mark turns a simple metal hinge into a symbol of quality assurance.
Benefits of BIS Certification for Steel Back Flap Hinges
Manufacturers gain multiple operational and market benefits from BIS registration:
- Customer Confidence: Buyers prefer ISI-marked hardware for quality reliability.
- Competitive Edge: Certified products get priority in B2B contracts and exports.
- Reduced Risk: Avoids product recall and legal penalties under the Quality Control Order.
- Improved Sales: Retailers and distributors trust certified brands for consistent supply.
- Brand Credibility: Demonstrates adherence to India’s strict quality and safety protocols.
Step-by-Step Process for BIS Certification for Steel Back Flap Hinges
The certification process involves product testing, document submission, and BIS evaluation.
Step 1 – Identify Standard
Confirm the applicable standard: IS 3843:1995 – Continuous (Piano) and Back Flap Hinges (Steel).
Step 2 – Sample Testing
Submit hinge samples to a BIS-recognized laboratory for testing as per IS 3843:1995.
Step 3 – Documentation
Prepare and submit the following documents:
- Factory license and GST certificate
- Product drawings and process flow
- In-house test reports
- Details of manufacturing machinery and equipment
- Quality control plan
Step 4 – Application Filing
Submit the BIS online application along with the test report.
Step 5 – Factory Inspection
BIS officials conduct an on-site audit to verify production, testing facilities, and quality control systems.
Step 6 – Grant of License
After successful evaluation, BIS issues a license to use the ISI mark for the specific product type.

Validity and Renewal of BIS License
- The BIS License is valid for two years from the date of issuance.
- It can be renewed every two years by submitting updated documents, test reports, and renewal fees.
- If the license is not renewed within the due date, it lapses and requires re-application.
Timely renewal ensures continued market access and uninterrupted production.
Common Challenges Manufacturers Face
Even experienced manufacturers face hurdles such as:
- Testing delays due to limited BIS-approved labs.
- Documentation confusion during application.
- Non-compliance in raw material grades leading to report rejection.
- Factory audit issues if proper quality systems aren’t in place.
Addressing these early with proper guidance reduces both time and cost during certification.
Cost of BIS Certification
The total cost varies depending on production scale, testing fees, and number of product variants.
Typically, it includes:
- BIS application fee
- Laboratory testing charges
- Factory inspection and audit expenses
- Annual license fee
While the cost is moderate, the long-term returns in terms of trust, business growth, and compliance are far higher.
