Introduction
In India’s market, product quality and safety are not consumer choices, they are obligations. With rapid industrial growth and an increasing amount of imports, the Indian Government has responded with tightening regulations for the products available for purchase in the country, making sure they are safe, reliable, and of a consistent quality.
BIS and ISI are two of the expressions that confuse the most manufacturers, importers and even consumers, because most people think they are same, however, they are interdependent and different. It is key for any business which plans to comply with Indian standards and any consumer that wants guarantees of quality to understand then differences between BIS vs ISI.
This blog will give you a detailed analysis of BIS vs ISI, how they operate, what makes them different, and why both are important within the quality system in India.
What is BIS?

Bureau of Indian Standards (BIS) – India’s National Certification Authority
The Bureau of Indian Standards (BIS) is the national standards body of India, functioning under the Ministry of Consumer Affairs, Food and Public Distribution. It develops standards, conducts quality control through its certification, and operates a certification mechanism, both for domestic products and products from overseas.
Key Functions of BIS:
- Granting ISI Marks for products
- Operating Compulsory Registration Scheme (CRS) for electronics
- Approving FMCS for foreign manufacturers
- Providing Hallmarking for gold and jewellery
- Ensuring standardization and safety across industries
BIS is like RBI in finance — the final authority that ensures everything meets the law.
What is ISI Certification?
ISI is abbreviated for the Indian Standards Institute — that was the one-time name of BIS. While BIS is the organization, ISI is widely accepted to be known as the “ISI Mark.“
The ISI mark is a certification symbol issued by BIS for specific products that conform to Indian Standards (IS codes).
ISI Mark Certification – The Trusted Symbol of Indian Quality

- It’s used on products ranging from electrical appliances to cement, PVC pipes to LPG cylinders.
- ISI Mark It is one of the oldest and popular certifications in India.
- The ISI Mark is indicative of a product being in conformance with a particular Indian Standard (IS) provided and issued by BIS.
- Consumers become accustomed to recognizing ISI with safety and reliability.
Products under ISI Certification
There are thousands of products that require the ISI Mark certification, but also products relevant to safety, health, performance. A few examples include:
- Electrical goods including switches, heaters, cables
- Kitchen utensils including pressure cookers, LPG cylinders
- Cement and Steel products
- Packaged drinking water
- Helmets and protective equipment.
If you’re buying a pressure cooker, a fan, or a helmet — look for the ISI mark. It tells you the product meets BIS-defined standards like IS 302 or IS 4151.

BIS vs ISI for Importers and Exporters
Compliance Impact on Global Trade
If you’re an importer or Amazon seller, understanding BIS vs ISI is critical.
- Without BIS approval, customs clearance is denied.
- ISI without valid BIS license = legal violation.
- FMCS mandatory for foreign exporters sending BIS-covered goods to India.
Benefits of BIS Certification
Whether you are a manufacturer, importer or exporter, getting BIS certification is more than a simple compliance box to tick, it is an investment in credibility, safety, and access to the market.
Here are some of the key benefits of BIS Certification:
1. Legal Compliance & no Penalties
- BIS is mandatory for some products; only products that have compliance to BIS standards and have been certified can be sold. Uncertified goods may be fined, seized, or imprisoned as per BIS Act, 2016.
2. Greater Market Access
- Certified products have access to government tenders, acceptance for public procurement and e-marketing sites like Amazon and Flipkart
3. Increased Brand Trust
- Consumers in India identify ISI mark and BIS Mark as quality marks and safety.
4. Further Export Opportunities
- Indian export establishments can face less regulatory and trade inertia for products related to BIS, GCC, Africa and SAARC nations.
5. Reduced Product Returns and Complaints
- With BIS-mandated product testing, your defect rate drops drastically — saving cost and brand reputation.
6. Insurance and Liability Advantage
- Insurers favour certified products. In case of damage or fire, non-BIS-certified products often void claims.
7. Support During Product Recalls or Audits
- BIS-certified companies receive better legal and technical support during investigations or quality-related litigation.
Get the License
Manufacturers often misuse the ISI mark without understanding that each product needs an individual license under a specific IS code.
Using the ISI symbol without BIS approval is a punishable offence under Section 17 of BIS Act 2016 — with imprisonment up to two years and/or a ₹5 lakh fine.
