ISI Mark Registration in Delhi 2026: Process & Cost

Imagine manufacturing a product, investing money in machines, arranging workers, and preparing to launch it in the market. Everything is ready, but suddenly a buyer asks for an ISI Mark Certificate. You may wonder whether the certification is compulsory, how much it costs, which documents are required, or how long the approval process will take.

These questions are common among first-time manufacturers.

ISI Mark Registration in Delhi is a process through which eligible manufacturers obtain a BIS licence to use the ISI Standard Mark on products that comply with the relevant Indian Standards. Manufacturers in Delhi NCR can obtain professional assistance from Compliance Calendar LLP for understanding BIS requirements, preparing documents, and managing certification formalities.

What Is ISI Mark Registration?

ISI Mark Registration refers to obtaining a product certification licence from the Bureau of Indian Standards under its applicable ISI Mark Scheme. The certification confirms that the manufacturer has demonstrated conformity with the requirements of the relevant Indian Standard and the prescribed certification conditions. Products manufactured under a valid BIS licence may carry the prescribed ISI Mark along with the relevant licence identification, subject to marking requirements.

For example, where a particular category of electrical appliance is covered under mandatory BIS certification, the manufacturer must obtain the required approval before supplying the product in circumstances covered by the relevant QCO.

However, not every electrical or industrial product comes under the same certification framework.

Is ISI Mark Registration Mandatory in Delhi?

ISI Mark Registration is not compulsory for every product manufactured or sold in Delhi. The requirement depends on the product category and whether the Central Government has issued an applicable Quality Control Order.

A QCO makes compliance with specified Indian Standards mandatory for the products it covers, subject to commencement dates, exemptions, and other conditions. Where mandatory certification applies, manufacturing, importing, selling, or distributing a covered product without the necessary certification may violate the applicable legal requirements.

Products That May Require ISI Mark Certification

Several industrial, electrical, construction, chemical, and consumer product categories are covered under the BIS Scheme-I certification framework.

Examples of product groups appearing in BIS mandatory certification listings include:

Product category	Certification considerations
Electrical appliances	Relevant safety standards and applicable QCOs
Industrial tools	Product-specific performance and safety standards
Electrical accessories	Applicable construction and electrical safety requirements
Building materials	Relevant material and quality standards
Chemical products	Composition, purity, and technical requirements
Safes and security equipment	Applicable construction and performance standards
Metal products and utensils	Relevant product and material specifications

These are broad categories, not a statement that every product within them requires an ISI licence. The exact product, Indian Standard, notification, and implementation date must be checked individually.

Eligibility Criteria for ISI Mark Certification

Manufacturers applying for certification must demonstrate their ability to consistently manufacture products meeting the relevant Indian Standard.

Manufacturing Infrastructure

The applicant must have suitable manufacturing facilities and machinery for the product proposed for certification. BIS may examine whether the available infrastructure is sufficient to manufacture the product according to the declared process.

Quality-Control System

The manufacturing unit should maintain appropriate quality-control arrangements. Depending on the product, these may include incoming material checks, production-stage inspections, finished-product testing, and maintenance of quality records.

Product Testing Facilities

The manufacturer should have the testing capabilities prescribed for the product and applicable certification route. Some testing may require specialized equipment or testing through approved external arrangements, subject to BIS guidelines.

Compliance with Indian Standards

The product must meet all applicable requirements of the identified Indian Standard. Simply maintaining a factory, purchasing machinery, or submitting documents does not establish compliance. These requirements form part of BIS's published manufacturer eligibility and licensing guidance.

Documents Required for ISI Mark Registration in Delhi

Documentation plays an important role in the application process. Manufacturers should generally prepare the following information, depending on product-specific requirements.

Document	Purpose
Business registration proof	Establishes applicant identity
Factory address details	Identifies the manufacturing location
Manufacturing process flowchart	Explains production stages
Machinery list	Shows available manufacturing infrastructure
Testing equipment list	Identifies product testing capabilities
Calibration records	Supports testing equipment accuracy
Product specifications	Establishes product scope
Quality-control records	Demonstrates inspection arrangements
Authorized signatory details	Identifies the application representative
Test reports, where required	Supports product conformity assessment

Additional technical information may be necessary for specific product standards.

Step-by-Step ISI Mark Registration Process in Delhi

Step 1: Identify the Applicable Indian Standard

The first step is identifying the correct Indian Standard. This decision depends on the product's nature, intended use, specifications, and technical characteristics. For instance, different varieties of electrical or mechanical products may require different testing methods and standards.

Choosing an incorrect standard can create avoidable difficulties during the certification process.

Step 2: Conduct a Manufacturing Unit Assessment

Before applying, manufacturers should review their factory infrastructure and determine whether the required production controls and testing arrangements are available. This assessment helps identify deficiencies that may need correction.

For example, testing instruments may require calibration, or additional quality-control records may need to be established.

Step 3: Prepare the Technical Documentation

The applicant must prepare relevant factory information, manufacturing details, equipment lists, technical specifications, and other prescribed records. Document consistency is important.

Details entered in the BIS application should match the supporting documents and the actual manufacturing setup.

Step 4: Apply Through the BIS Online Portal

Once the factory is prepared, the manufacturer can submit the application through the Manakonline portal. Application information and applicable fees must be submitted according to the prescribed process.

BIS provides online application guidance through its official website.

Step 5: Complete Product Testing

Product conformity must be established under the applicable BIS assessment procedure. Testing may be conducted through recognized laboratories, at the manufacturing premises, or through the combinations permitted by the relevant certification route.

A failed test may require investigation, corrective measures, and further testing.

Step 6: Factory Inspection and Verification

Under the applicable procedure, BIS assesses the manufacturer's infrastructure, quality-control arrangements, and testing capabilities. During the assessment, the manufacturer may be required to demonstrate production and testing arrangements and provide supporting records.

Step 7: Rectify Deficiencies, If Any

If BIS identifies deficiencies, the applicant may need to submit explanations or take corrective action. The required response will depend on the observations raised during processing. Responding accurately and promptly can help reduce avoidable delays.

Step 8: Obtain the BIS ISI Licence

After BIS is satisfied that the applicable requirements have been fulfilled, it may grant the certification licence. The manufacturer can then use the prescribed ISI Mark for products within the approved licence scope, subject to ongoing compliance requirements.

ISI Mark Registration Fees in Delhi

One of the most common questions manufacturers ask is: How much does ISI Mark Certification cost?

There is no single fixed total certification cost applicable to every product.

The overall expense depends on the product category, Indian Standard, testing requirements, manufacturing location, and applicable BIS fee schedules.

Fee component	Explanation
Application fee	Fee applicable to the certification application
Inspection expenses	Charges associated with the prescribed assessment
Product testing charges	Depend on tests, samples, and laboratory arrangements
Annual licence fee	Applicable according to the BIS fee schedule
Marking fee	Product-specific charges for use of the Standard Mark
Professional consultancy fee	Charged separately by the consultant, if engaged

Additional costs may arise if the factory needs testing instruments, infrastructure improvements, or corrective testing. Manufacturers should request a product-specific quotation rather than relying on a generic estimated amount. BIS publishes its applicable fee information and product-specific marking fee details through its licensing guidance.

How Long Does ISI Mark Certification Take?

The certification timeline varies depending on the product, application completeness, testing requirements, applicable licence-granting route, and readiness of the manufacturing unit. A factory with suitable testing facilities and complete documents may face fewer avoidable delays than an applicant who must first develop additional infrastructure.

Common reasons for delays include incomplete application documents, failed product tests, unavailable testing arrangements, and delays in responding to BIS queries. Manufacturers should therefore begin planning certification before their intended production launch or supply commitment. No consultant can guarantee a particular approval date because the final decision depends on BIS and completion of the prescribed assessment requirements.

Latest BIS ISI Mark Updates in 2026

1. Changes in Mandatory Certification Coverage

In 2026, BIS's compulsory certification listings include amendments and implementation provisions for various industrial and consumer products. Manufacturers should examine the latest applicable QCO instead of relying on older product lists. Some notifications have also been affected by transition facilitation and exemption provisions.

2. Household and Similar Electrical Appliances

The BIS Scheme-I list includes the household and similar electrical appliances safety framework involving IS 302 (Part 1):2024 / IEC 60335-1:2020. Relevant 2026 amendments and transition provisions appear in the official listing. Businesses dealing in vacuum cleaners, appliances for heating liquids, cooking equipment, and other potentially covered products should examine their applicable classification and notification before assuming that a specific ISI licence is required.

3. New and Revised Indian Standards

Manufacturers should track revised Indian Standards and any transition arrangements affecting their existing or proposed licences. A new version of a standard does not necessarily mean that every existing licence becomes invalid immediately. The applicable BIS transition directions and regulatory notifications must be considered.

4. Greater Importance of Product-Specific Compliance Planning

The government maintains lists of products under compulsory certification and upcoming QCO implementation dates. For manufacturers, this makes early product classification and standard identification especially important.

5. Online Application Requirements

Digital filing continues to be an important part of BIS certification. Domestic Scheme-I applicants submit applications online, and foreign manufacturers applying through FMCS have also been required to use online application submission since June 2026.

Difference Between ISI Mark and BIS CRS Registration

Many businesses confuse ISI Mark Certification with BIS CRS Registration. Although both operate under the Bureau of Indian Standards, they follow different certification frameworks.

Basis	ISI Mark	BIS CRS
Scheme	Generally Scheme-I	Scheme-II
Common focus	Products governed by applicable Indian Standards and ISI licensing	Notified electronics and IT goods, and other products covered by CRS
Certification form	Licence for use of ISI Standard Mark	Registration under CRS
Assessment	Manufacturing capabilities and conformity assessments under Scheme-I	Prescribed testing and registration procedures under Scheme-II
Application	Through applicable BIS process	Through applicable CRS process

For example, certain laptops and electronic equipment are covered under the Compulsory Registration Scheme rather than the conventional ISI Mark Scheme. Manufacturers must select the correct route before applying.

Renewal of ISI Mark Licence

Obtaining the licence is not the end of the compliance process. Manufacturers must continue to meet the relevant Indian Standard and comply with licence conditions. Renewal is required according to the applicable BIS regulations and licence validity.nBusinesses should maintain testing records, quality-control procedures, required marking practices, and supporting documents.

Any changes affecting the approved manufacturing process or licence scope should be handled in accordance with BIS requirements. A consultant can assist with renewal documentation and understanding continuing compliance responsibilities.

Common Reasons for BIS Certification Delays

Although the application process may appear straightforward, certain practical issues can slow it down. Incorrect standard selection: When the selected Indian Standard does not match the product, the application may require correction or a revised approach. Incomplete testing arrangements: The factory may lack required instruments or adequate quality-control capabilities. Product test failure: The manufactured product may not satisfy one or more technical requirements.

Document inconsistencies: Factory details, product specifications, and application records may not match. Unresolved BIS queries: Delays in submitting clarification documents or implementing corrective actions can extend processing. Understanding these issues in advance can help manufacturers prepare a stronger application.
