What Is BIS ISI Mark Certification?

BIS ISI Mark Certification is a product certification scheme under which eligible manufacturers receive a licence to use the applicable BIS Standard Mark on products that conform to the relevant Indian Standard.

BIS, or the Bureau of Indian Standards, is India's national standards body. It develops Indian Standards and administers conformity assessment schemes to support product quality, safety, and reliability.

The ISI Mark indicates that a product covered by the relevant certification scheme conforms to the applicable Indian Standard within the scope of the licence.

BIS certification is generally voluntary unless made mandatory for a particular product under a Quality Control Order (QCO) or another applicable legal requirement. Manufacturers should verify whether their products are subject to mandatory certification before manufacturing, importing, or selling them in India.

Why Is BIS ISI Mark Certification Important?

BIS ISI Mark Certification is important for manufacturers because it provides a recognized framework for demonstrating conformity with relevant Indian Standards.

Key benefits include:

Product conformity: Helps demonstrate that a certified product meets the applicable Indian Standard.
Regulatory compliance: Supports compliance with mandatory certification requirements where applicable.
Consumer confidence: Provides an identifiable Standard Mark for products covered by the licence.
Market access: Helps eligible manufacturers meet relevant product certification requirements before marketing regulated products.
Quality management: Encourages appropriate production controls, quality checks, and testing capabilities.
Business credibility: Supports a more structured approach to product quality and compliance.

Certification does not eliminate the need for ongoing quality control. Licence holders must continue meeting applicable requirements, including those relating to production, marking, and surveillance.

Which Products Require BIS ISI Mark Certification in India?

The products covered by BIS certification vary by Indian Standard and applicable regulatory notification. Certain products are subject to mandatory certification, while others may fall under voluntary certification arrangements.

Steel products and specified metal materials.
Pressure cookers and certain household products.
Automotive components covered by applicable standards.

BIS ISI Mark Certification Process in India

The BIS ISI certification process depends on the product, applicable Indian Standard, and procedure selected under the relevant BIS scheme. The general stages are outlined below.

Step 1: Identify the Applicable Indian Standard

The first step is to determine which Indian Standard applies to the product. The standard defines the relevant technical and quality requirements.

The manufacturer should also verify whether certification is mandatory and identify any applicable QCO or implementation date.

Brand Liaison can assist with understanding the relevant standard and certification pathway.

Step 2: Assess Manufacturing and Quality-Control Capabilities

The manufacturer must have the infrastructure and capabilities required to produce products conforming to the relevant standard.

Depending on the product, this may include:

Appropriate manufacturing machinery and equipment.
Documented production processes.
Quality-control procedures.
Testing equipment and competent personnel.
Facilities for maintaining product quality.
Records required under the applicable product manual or scheme.

The exact requirements depend on the Indian Standard and the applicable BIS certification procedure.

Step 3: Prepare the Required Documents

The applicant prepares the relevant business, factory, technical, and quality-control documents.

The documentation should be consistent with the product details, manufacturing location, and scope of the application.

Step 4: Submit the BIS Application

Applications for BIS product certification are submitted through the official online application system, subject to the applicable procedure.

The applicant must provide the prescribed information and pay the applicable fees.

Step 5: Arrange Product Testing

Product samples are tested according to the applicable Indian Standard and certification procedure.

Testing may be conducted through an appropriate BIS laboratory, a BIS-recognized laboratory, or through an approved testing arrangement, depending on the applicable process.

The product must meet the relevant requirements before a licence can be granted.

Step 6: Complete the Applicable Factory Assessment

Where required, BIS assesses the manufacturing premises and the manufacturer's ability to maintain conformity with the applicable standard.

The assessment may cover manufacturing infrastructure, production controls, quality assurance, and testing capabilities.

The precise assessment requirements depend on the product and certification procedure.

Step 7: Resolve Queries and Complete Requirements

If additional information, corrective action, or further testing is required, the applicant must address the outstanding requirements.

Timely responses and accurate documentation can help avoid preventable delays.

Step 8: Obtain the BIS Licence

After the applicable requirements have been fulfilled and the application is approved, BIS may grant the licence to use the Standard Mark within the specified scope.

The manufacturer must comply with the licence conditions and ongoing surveillance requirements. The ISI Mark must not be used as though a licence has been granted before the required authorization is obtained.

Brand Liaison can assist clients with procedural guidance and coordination throughout these stages, but the final certification decision rests with BIS.

BIS ISI Mark Certification vs. BIS CRS Registration

BIS ISI Mark Certification and BIS CRS Registration are different certification routes. The correct route depends on the product category and the applicable regulatory requirements.

BIS ISI Mark Certification generally refers to licensing under the applicable product certification scheme, commonly Scheme I, for products conforming to their relevant Indian Standards.

BIS CRS Registration refers to the Compulsory Registration Scheme, which applies to notified product categories under its specific requirements.

Manufacturers should not assume that one certification can replace the other. They should verify the product's applicable standard, notification, and certification scheme before applying.

Brand Liaison assists businesses with both ISI Mark Certification and CRS Registration, helping them understand the relevant compliance pathway.

Common Challenges in BIS ISI Mark Certification

Manufacturers may face several challenges during the certification process.

Incorrect Standard Identification

Selecting an incorrect Indian Standard can lead to application and testing complications. The product's specifications and intended use should be evaluated carefully.

Incomplete Documentation

Missing technical details, manufacturing records, or quality-control information may result in queries and additional work.

Product Testing Issues

If the product fails to meet a requirement, the manufacturer may need to investigate the cause, make corrections, and follow the applicable retesting procedure.

Factory Readiness

Manufacturers must be prepared to demonstrate the necessary infrastructure, quality controls, and testing capabilities where required.

Ongoing Compliance

Obtaining the licence is not the end of the process. Manufacturers must continue complying with licence conditions, product requirements, marking rules, and applicable surveillance activities.

Professional guidance can help businesses prepare for these requirements, but the manufacturer remains responsible for ensuring that its products and production processes comply with the applicable rules.
