Introduction

Maintaining product quality and safety is important for both manufacturers and consumers in India. To make sure that products meet the required quality and safety standards, the Government of India has introduced different certification and compliance systems. One of the most important certifications is the BIS ISI Mark Certification.

The BIS ISI Mark Certification indicates that a product has been checked against the applicable Indian Standard under the relevant BIS certification scheme before being sold or imported in the Indian market. For manufacturers, importers, and online sellers that are planning to sell the notified products in India, understanding BIS and ISI Mark certification is essential. 

In this guide, Brand Liaison explains what BIS is, what the ISI Mark means, which products may require certification, the certification process, documents, benefits, and other important details.

Understanding BIS

BIS stands for Bureau of Indian Standards. It is India's national standards body that works under the Ministry of Consumer Affairs, Food and Public Distribution.

BIS is responsible for developing and maintaining standards for a wide range of products. These standards help ensure that products meet defined requirements related to quality, safety, performance, and reliability.

BIS also operates product certification schemes under which manufacturers can demonstrate compliance with applicable Indian Standards. Therefore, whether a product needs BIS certification depends on the product category, applicable Indian Standard, and current regulatory requirements.

What is ISI Mark Certification?

The ISI Mark is a certification mark used for notified products listed under the BIS product certification scheme based on the applicable Indian Standard. It is issued by BIS for selling and importing the notified products in the Indian market

If a product carries a valid ISI Mark, it generally ensures that the product meets the BIS certification requirements and conforms to the relevant Indian Standard. The ISI Mark is commonly seen on products such as electrical appliances, cement, steel products, pressure cookers, cables, switches, construction materials, and many other notified products.

What is the Difference Between BIS and ISI Mark?

BIS and ISI are closely connected, but they are not the same thing. Here is the difference between the two terms:

For businesses, ISI mark certification provides a structured way to ensure that their products comply with the applicable Indian Standard.

Who Needs BIS ISI Mark Certification?

BIS ISI Mark Certification is a mandatory requirement for manufacturers, importers, and online sellers who deal in the notified products in India.

1. Indian Manufacturers

3. Indian Importers

4. Brand Owners or Startups

Procedure for Getting ISI Mark in India

The BIS certification process varies for domestic and foreign manufacturers. Here is a common process that they can follow to get the ISI mark approval:

Step 1: Identify the Applicable Indian Standard

The first step is to determine the applicable Indian Standard for the notified product. It requires checking the product's specifications, technical characteristics, and applicable regulations.

Step 2: Prepare the Required Documents

The applicant should prepare the documents as per the prescribed checklist. For foreign manufacturers, an Authorized Indian Representative (AIR) must be appointed to proceed with the application. 

Step 3: Submit the Application

After preparing the required documents, the applicants have to submit the application to BIS authorities to start the registration process. BIS reviews the application and supporting documents.

Step 4: Factory Inspection by BIS Officials

BIS officials inspect the manufacturing facility. During the inspection, areas such as production facilities, quality control arrangements, testing capabilities, raw materials, manufacturing processes, and product samples may be reviewed.

Step 3: Testing of the product

The sample product is tested according to the applicable Indian Standard. Depending on the certification requirements, testing is done in a BIS-recognized or otherwise permitted laboratory. 

Step 8: Evaluation by BIS

BIS reviews the application, test results, and other relevant information. If there is incorrect or wrong information, the applicant may need to provide clarification or take corrective action.

Step 9: Grant of BIS License

If the applicable BIS requirements are fulfilled, BIS grants the BIS ISI Mark certification to the applicant. They can then use the ISI Mark on the certified product according to the applicable marking requirements and license conditions.

What are the benefits of BIS ISI Mark Registration?

BIS ISI Mark Registration ensures that certified products are safe to use in India. It is one of the main benefits of getting certified. The following are some more benefits that you must know about the BIS ISI Certification:

Eliminates the Risk of Accident

The ISI Mark helps users to identify safe products that have been certified under the applicable BIS requirements. It eliminates the risk of accidents and harm to the users.

Ensures Safety and Quality

BIS ISI Mark encourages manufacturers and importers to maintain consistent product quality and follow the applicable Indian Standard to ensure safety.

Meeting Mandatory Legal Requirements

For the notified products covered under the mandatory BIS applicable product list, BIS certification helps businesses meet the applicable legal requirements for safety and quality to sell them in the Indian market.

Improves Market Acceptance

The certified products have better acceptance among customers, distributors, institutions, and business buyers. It increases sales and market opportunities for the manufacturers and importers in India.

Reduces Legal Compliance Risks

If there is compliance with the applicable certification requirements, businesses can reduce the risk of legal problems related to selling products without the required certification.

What happens if the notified products are sold without BIS Certification in India?

Non-compliance with BIS requirements can result in legal action, depending on the applicable law and order. Manufacturers and importers may face the following issues related to manufacturing, importing, and selling the uncertified product.

For Foreign Manufacturers

  • No customs clearance
  • Financial losses
  • Loss of market opportunities
  • Product seizures

For Indian Manufacturers

  • Imprisonment up to 2 years
