Introduction
If you manufacture products in India or plan to sell products in the Indian market, BIS ISI Certification is an important compliance requirement for eligibility in the market. The terms BIS Certification and ISI Certification are often used together, but there is a simple way to understand the relationship between the two. Skipping the mandatory compliance can lead to risks for businesses, whereas adherence to the compliance requirements leads to smooth market entry and trade in India.
This guide explains the ISI Certificate process, cost, documents, eligibility, testing, timelines, as well as consultant services in simple language so that manufacturers can understand what to expect before applying to the BIS.
What is an ISI Certificate?
An ISI Certificate is commonly used to describe the BIS licence that permits an eligible manufacturer to use the ISI Standard Mark on a certified product. It is a mandatory certification required for all notified products to sell or import in the Indian market.
The Indian Standards Institution (ISI) became associated with the quality mark. Today, the Bureau of Indian Standards (BIS) administers this product certification system. Under Scheme-I, BIS grants certification to eligible manufacturers for using the Standard Mark on products conforming to the relevant Indian Standard.
In simple words:
Indian Standard → Product Testing → Factory Assessment → BIS Licence → ISI Mark
The ISI Mark therefore should not be treated as simply a logo that a company can print on packaging. It represents conformity with the applicable Indian Standard under a valid BIS licence, to be eligible for trading notified products in the Indian market.
Is BIS ISI Certification Mandatory for Every Product?
No. This is one of the most common misunderstandings about ISI certification. The BIS certification is mandatory only for those products that have been notified by the BIS. The BIS certification is also voluntary for other products, and manufacturers can obtain the ISI mark to ensure conformance with the BIS regulations. Therefore, there are two broad situations:
1. Mandatory BIS Certification
If your product is covered by an applicable QCO requiring BIS certification, you must obtain the relevant BIS licence before selling or importing the goods in India.
2. Voluntary BIS Certification
If certification is not compulsory for your product, a manufacturer may still seek BIS certification where the relevant certification scheme is available and commercially useful.
This can be particularly relevant when buyers, tenders, customers or market expectations require conformity with an Indian Standard.
Before applying, businesses should always check:
- Product category
- Applicable Indian Standard
- Latest QCO
- Effective date
- Certification scheme
- Product-specific BIS requirements
This prevents businesses from applying under the wrong scheme or assuming that every product needs an ISI Mark.
What is BIS Certification in India?
The BIS is the official body responsible for establishing standards and safety parameters of all notified products. It is an officiating authority that oversees the functioning of and grants the relevant licenses to the applicable products and businesses. The BIS can simply be understood as an umbrella term that grants licenses under various schemes, including BIS ISI, BIS CRS, BIS Scheme X, and more. So when a business talks about a BIS certification in India, it is important to check the applicable Scheme and compliance requirements to avoid confusion.
BIS Certification vs ISI Certification: What is the Difference?
The two terms BIS certification and ISI certification are closely connected.
| BIS Certification | ISI Certification |
| Certification issued under the BIS conformity assessment framework | Commonly refers to BIS product certification involving the ISI Standard Mark |
| Covers different BIS conformity assessment schemes | Usually associated with Scheme-I product certification |
| Can include different forms of conformity assessment | Primarily refers to products certified against applicable Indian Standards |
| BIS is the certification authority | BIS grants the licence to use the Standard Mark ISI Mark |
| Applicable scheme depends on the product and regulation (ISI, CRS, Scheme X) | Used where the product falls under the relevant ISI Mark certification route |
So, when someone searches for an ISI Certificate, they are often looking for a BIS licence to use the ISI Standard Mark for an applicable product, to make them eligible for sales and imports.
If you do not know which BIS Scheme your product falls under, check your eligibility for a BIS certification today.
Who Needs an ISI Certificate in India?
The BIS ISI Certification is mainly required by business entities as follows:
- Indian manufacturers
- Foreign manufacturers under applicable BIS schemes
- Manufacturers producing products covered by compulsory QCOs
- Businesses voluntarily seeking BIS certification for eligible products
- Manufacturers whose customers or market requirements require BIS-certified products
The important point is that BIS certification is manufacturer- and product-specific. An importer cannot simply obtain a BIS licence for a foreign manufacturer's product under the ordinary domestic manufacturer route. They may request a BIS licence copy from the manufacturer to ensure continued compliance in the Indian market.
BIS Certification for Foreign Manufacturers
For foreign manufacturers, BIS has the Foreign Manufacturers Certification Scheme (FMCS), under which BIS grants licences to foreign manufacturing premises for products conforming to relevant Indian Standards.
Under the FMCS process, the foreign manufacturer must nominate an Authorized Indian Representative (AIR) as required by BIS. Therefore, foreign manufacturers should not assume that an Indian importer can simply apply for a domestic manufacturer licence on their behalf. Following the BIS guidelines is important for Indian market compliance.
Which Products Require ISI Certification?
The list of products that require a mandatory ISI mark certification is extensive and continues to change as new standards and QCOs are introduced. Therefore, it is better to identify the exact product and Indian Standard instead of relying on a general list of "ISI products."
Examples of product categories where ISI certification is mandatory generally include:
- Cement and construction materials
- Electrical appliances
- Electrical cables
- Steel and metal products
- Pressure equipment
- Chemicals
- Automotive components
- Pipes and fittings
- Safety-related products
- Household products
- Industrial equipment
What is the step-by-step BIS ISI Certification Process?
The BIS ISI certification process may appear complicated at first, but it can be understood as a series of practical steps as follows:
Step 1: Identify the Product and Applicable IS
The first step is to identify the exact product and determine the relevant Indian Standard.
The standard should cover the product, its specifications, as well as applicable requirements.
Step 2: Check Whether BIS Certification Is Mandatory
Once the standard is identified, determine whether the product is:
- Covered by a mandatory QCO
- Eligible for voluntary BIS certification
- Covered under another BIS certification scheme such as CRS, Scheme X, or other
Step 3: Review the BIS Product Manual
BIS provides product-specific technical manuals in order to help manufacturers understand infrastructure, testing, inspection, as well as various other certification requirements. The product manual can help a manufacturer understand the following:
- Manufacturing facilities
- Testing equipment
- Quality control
- Sampling
- Inspection
- Scheme of Inspection and Testing
- Product-specific requirements
Step 4: Check Manufacturing Infrastructure
BIS does not only look at paperwork. The manufacturer needs to demonstrate that it has the appropriate infrastructure to consistently produce products that will conform to the applicable BIS regulations.
As per BIS, the manufacturers who are applying for a licence must have the manufacturing infrastructure, appropriate process controls, quality control as well as testing capabilities for the relevant product.
Step 5: Arrange Testing
Testing is a major part of BIS ISI certification. The purpose is basically to establish that the product conforms to the relevant Indian Standard. The testing for notified products has to be done only in laboratories that have been accredited by the BIS.
Step 6: Prepare the BIS Application
Once the applicant is ready, the application and supporting documents can be prepared.
Step 7: BIS Factory Inspection
Factory assessment is an important part of the BIS certification process. BIS may visit the manufacturing premises to check:
- Manufacturing infrastructure
- Production process
- Quality control
- Testing facilities
- Technical manpower
- Raw material controls
- Compliance with the applicable Indian Standard
Samples may also be collected for testing.
Step 8: Product Sample Testing
The product samples may be tested according to the applicable certification procedure.
The purpose is to verify whether the product actually meets the relevant Indian Standard.
Step 9: Address BIS Queries and Non-Conformities
During application scrutiny, inspection, or testing, BIS may identify issues that need clarification or correction by the applicant. The manufacturer may need to take corrective action and submit the required evidence on time to prevent further delays.
A top BIS ISI certification consultant in India can help the manufacturer understand the issue and prepare an appropriate response in a timely manner.
Step 10: Grant of BIS Licence
BIS can grant the licence to use the Standard Mark for the applicable products that are covered by the licence. However, it is important to note that the licence is not a single approval for every product made by the company. It is connected to the manufacturer, manufacturing premises, applicable standard, as well as the product categories covered.
Step 11: Use the ISI Mark Correctly
Once the licence is granted, the manufacturer can use the Standard Mark/ISI Mark according to the licence conditions and applicable marking requirements.
The manufacturer should not use the ISI Mark:
- Before receiving the applicable licence
- On products outside the licence scope
- On unrelated products
- In a way that violates BIS marking requirements
BIS specifically provides conditions governing the use or application of the Standard Mark.
It is relevant to note that the process of BIS certification for domestic manufacturers is different from the BIS FMCS process for foreign manufacturers entering the Indian market.
What Documents are Required for ISI Certification?
The exact document checklist depends on the product as well as the applicable Indian Standard. However, manufacturers should generally prepare commonly asked documents like:
- Legal address proofs of the factories
- Product specification
- Details of raw material, machinery, and testing equipments
- Details of QC Staff and other basic details of the factory
- Lab test reports of the product
- Main Application Form V
- ISI Application Fee
How much does an ISI Certificate Cost in India?
There is no single fixed ISI certification cost for every product. The total cost depends on several factors like type of product, testing requirements, additional compliance needs, technical specifications, consultancy appointed, etc. However, here is a simple breakdown of the general BIS certification cost in India:
| Component | Domestic Manufacturers | Foreign Manufacturers |
| Application Fee | ₹1,000 | ₹1,000 (Equivalent USD) |
| Sample Testing | As per the product & IS standard | As per the product & IS standard |
| Audit Fee | ₹7,000 per man-day | ₹7,000 per man-day |
| Minimum Marking Fee | Depends on product & IS | Depends on product & IS |
| License Fee | ₹1,000 | ₹1,000 (Equivalent USD) |
| Visiting Fee | Not applicable | As actual (airfare, visa, stay, etc.) |
| Additional Charges | May vary | May vary |
| Consultancy Fee | Varies | Varies |
What Happens After Getting the ISI Certificate?
Obtaining the licence is an important requirement for staying compliant, but compliance continues even after approval. A BIS licence holder may need to maintain the following even after getting the BIS ISI certification:
- Production controls
- Testing facilities
- Quality records
- Calibration
- Inspection and testing
- Product conformity
- Marking practices
- Records required under the applicable certification scheme
BIS also has procedures covering renewal, factory surveillance, market surveillance, retesting as well as dealing with product non-conformity. Manufacturers must know how to renew BIS certification on time, to ensure continued compliance in India and keep accessing market opportunities in an uninterrupted manner.
In simple terms:
Getting the BIS licence is the beginning of certified production, not the end of compliance in the Indian market.
Common Mistakes That Delay ISI Certification
Many businesses experience delays because of avoidable issues. Such common mistakes generally include:
Choosing the wrong Indian Standard
The entire application can become problematic if the product is linked to the wrong IS. It is important to check the Indian Standard and certification requirements and comprehensively understand BIS certification in detail before beginning the licensing process application.
Applying before the factory is ready
BIS checks the manufacturing and testing capabilities. Applying too early can create problems during inspection, especially if quality control measures and production systems are not in place.
Missing testing equipment
If the applicable product manual requires particular testing facilities, the manufacturer should be prepared accordingly to ensure compliance in the Indian market.
Incomplete documents
Missing or inconsistent documents can result in queries from BIS officials, leading to further delays in BIS certification.
Incorrect product varieties
The licence scope is connected to the varieties that have been covered under the BIS for mandatory certification. Manufacturers should carefully plan which products they want to include.
Test report mismatch
The tested sample as well as the submitted product should correspond appropriately in the BIS application.
Poor calibration records
Testing equipment as well as the measurement controls should be properly maintained where applicable, to prevent unavoidable delays in the grant of a BIS license.
Treating certification as only paperwork
BIS certification is based on manufacturing capability as well as product conformity, not just submission of the required documents.
