What is BIS Certification for Domestic Products?
The Bureau of Indian Standards (BIS) is India’s national standards authority responsible for setting quality, safety, and performance benchmarks for products sold in the Indian market. BIS Certification for Domestic Products ensures that a product complies with these prescribed Indian Standards (IS) before it is manufactured, sold, or distributed in India.
This certification acts as an official assurance that the product is safe for consumers, reliable in performance, and legally compliant with government regulations.
Key Highlights of BIS Certification
- Confirms compliance with applicable Indian Standards (IS)
- Ensures consumer safety, quality, and product reliability
- Mandatory for specific domestic products under the Product Certification Scheme (PCS)
Authorizes manufacturers to use BIS license numbers (CM/L) and approved certification marks
What is BIS ISI Mark?
The BIS ISI Mark is an official certification mark issued by the Bureau of Indian Standards (BIS) to indicate that a product complies with the applicable Indian Standards (IS). It is a key part of product safety certification in India and helps ensure that only BIS-approved domestic products reach consumers.
Originally introduced in 1955 by the Indian Standards Institute (now BIS), the ISI mark has become a widely trusted symbol of quality assurance, safety compliance, and regulatory conformity for domestic and household products.
The ISI mark is mandatory for several products, especially electrical appliances, building materials, and consumer goods, where safety and performance are critical. Each ISI-marked product carries a BIS license number (CM/L) along with the relevant IS standard number, allowing easy verification of BIS compliance for domestic products and ensuring traceability.
Difference Between BIS Certification and ISI Mark
Although the terms are often used together, BIS Certification and the ISI Mark serve different purposes in the certification process for domestic products.
Feature | BIS Certification | ISI Mark |
Purpose | Certifies that a product meets overall quality, safety, and regulatory requirements | Confirms that a product conforms to a specific Indian Standard (IS) |
Issuing Authority | Bureau of Indian Standards (BIS) | Bureau of Indian Standards (BIS) |
Scope | Applies to both voluntary and mandatory certification schemes | Applies only to products covered under the mandatory Product Certification Scheme |
Nature | Certification process and legal approval | Physical conformity mark displayed on the product |
Product Marking | BIS license number issued to the manufacturer | ISI mark with CM/L license number and IS standard number |
BIS Certification is the official approval process carried out by BIS, while the ISI Mark is the visible symbol of compliance placed on the product. In simple terms, BIS certifies the product, and the ISI mark shows that certification to consumers.
