A manufacturing company receives a large purchase order for a product covered under a mandatory Quality Control Order. The factory has completed production planning, raw materials have been purchased and the buyer expects dispatch within 30 days. During the final compliance review, the company discovers that it does not have a valid BIS licence or CM/L number.
This is not a minor documentation gap. The manufacturer may be unable to dispatch the goods, use the ISI Mark or legally sell the product after the applicable Quality Control Order becomes effective. Finished stock may remain blocked, testing may need to be repeated and customer commitments may be delayed by several weeks or months.
ISI Mark Certification for Manufacturers in India should therefore be planned before commercial production begins. Manufacturers need to identify the correct Indian Standard, confirm whether the product is covered by a Quality Control Order, prepare the factory laboratory and complete testing before using the Standard Mark.
The process is governed primarily by:
ISI Mark Certification is a product conformity licence granted by the Bureau of Indian Standards under Scheme-I. It allows a manufacturer to use the BIS Standard Mark, commonly called the ISI Mark, on products manufactured at an approved factory.
The licence is issued against a specific Indian Standard. It is not a general quality certificate for the entire company or all products manufactured at the facility.
For example, if a manufacturer produces 12 different product models, the licence will cover only those grades, varieties, ratings, sizes or models approved by BIS. Any product outside the approved scope cannot automatically carry the ISI Mark.
The licence is also factory-specific. A company operating 3 factories may need separate BIS licences for each manufacturing location, depending on where the certified product is produced.
An ISI-marked product generally displays:
BIS certification is voluntary for many products. However, the Central Government can make certification compulsory by issuing a Quality Control Order.
Once the Quality Control Order becomes effective, covered products cannot normally be manufactured, imported, stored, distributed or sold without conformity to the applicable Indian Standard and a valid BIS licence.
Manufacturers should not rely only on the commercial product name. Applicability may depend on technical specifications such as:
A manufacturer should check the applicable Quality Control Order at least 3 to 6 months before the planned production or market launch date.
Before applying, the manufacturer should confirm:
| Regulation or Requirement | Main Requirement | Timeline | Applicable To | Business Risk |
|---|---|---|---|---|
| BIS Act, 2016 | Compliance with compulsory standards | Before manufacture or sale | Manufacturers and importers | Seizure, penalty and prosecution |
| Scheme-I | Factory assessment and product testing | Before use of ISI Mark | Domestic and eligible foreign manufacturers | Application rejection |
| Quality Control Order | Mandatory certification requirement | Effective date mentioned in the order | Covered product categories | Production or sales stoppage |
| Indian Standard | Product specifications and testing | Continuous | Approved product scope | Sample failure |
| Product Manual | Testing, grouping and marking requirements | During application and licence operation | BIS licensees | Non-conformity |
| Scheme of Inspection and Testing | Internal quality control and test frequency | Throughout licence validity | Factory quality team | Suspension |
| BIS licence renewal | Continuation of licence | Normally before expiry | Existing licensees | Licence expiry |
BIS certification does not replace other factory approvals. A manufacturing unit may separately require Consent to Establish, Consent to Operate, Factory Licence, Fire NOC or hazardous waste authorization.
Similarly, obtaining environmental approvals does not remove the requirement to obtain BIS certification where the product is covered under a mandatory Quality Control Order.
Manufacturers frequently use the terms BIS registration and BIS certification interchangeably. However, BIS operates different conformity assessment routes.
Selecting the wrong route can result in incorrect testing, application rejection and loss of several weeks.
| Certification Route | Main Purpose | Applicable Applicant | Factory Inspection | Approval Type |
|---|---|---|---|---|
| ISI Mark or Scheme-I | Product certification against Indian Standard | Indian manufacturer and eligible foreign manufacturer | Normally required | BIS licence with CM/L number |
| CRS or Scheme-II | Registration of notified electronic and IT products | Manufacturer | Based on CRS process | BIS registration number |
| FMCS | Certification of foreign manufacturing units | Foreign manufacturer | Foreign factory inspection | BIS licence |
| Scheme-X | Certification of notified machinery and electrical equipment | Indian or foreign manufacturer | As applicable | Scheme-X licence |
A domestic trader or importer cannot normally obtain an ISI licence in its own name for a product manufactured at a foreign factory. The actual foreign manufacturing unit generally needs to apply under the Foreign Manufacturers Certification Scheme.
The first technical step is identifying the correct Indian Standard.
Products that appear similar in the market may have different standards based on their construction, application, material or performance requirements.
For example, a wrong standard selection can result in:
After identifying the standard, the manufacturer must study the Product Manual and Scheme of Inspection and Testing.
The Product Manual normally explains:
If a company manufactures 20 product sizes, BIS may not require testing of all 20 sizes. However, representative samples must be selected according to the grouping guidelines.
Incorrect grouping can result in approval for only a limited product range.
Manufacturers should not apply merely because production machinery has been installed.
The factory must be able to demonstrate consistent production, quality control and testing capability.
During the factory visit, BIS may verify:
The normal factory visit for an Indian manufacturer may be completed in approximately 1 working day. More time may be required for complex products, multiple production lines or large product scopes.
The factory should be ready to conduct an actual production run during inspection.
A factory may face delays when:
The exact document list depends on the product, business structure and Indian Standard.
However, most applications require business, factory, technical and product documentation.
Business documents confirm the legal identity of the manufacturing entity.
Common documents include:
Factory documents establish that the applicant controls the declared manufacturing facility.
These may include:
Quality documents demonstrate the factory’s ability to maintain product conformity.
These may include:
Product documents establish the requested licence scope.
These may include:
Company name, factory address and product description should remain consistent across all documents.
Even a small mismatch in the factory address may lead to a clarification query and delay the application by 7 to 15 working days.
The BIS application process should begin only after the factory and product are technically ready.
The manufacturer should review the product description, Quality Control Order, Indian Standard and implementation date.
The assessment should confirm:
This step may take approximately 2 to 5 working days.
The factory’s machinery, laboratory and quality system should be compared with the Indian Standard and Product Manual.
The assessment should identify:
Depending on factory readiness, corrective action may take 1 to 4 weeks.
A representative product sample is prepared according to grouping guidelines.
The sample may be tested in a BIS-recognised or accepted laboratory, depending on the application route.
Testing time may vary from:
The manufacturer submits the application through the BIS online system.
The application generally includes:
BIS reviews the documents and may raise queries.
Common queries relate to:
A manufacturer should respond to queries within the portal timeline to avoid closure or rejection.
The BIS officer visits the manufacturing facility.
The inspection may include:
If the factory assessment and product test results are satisfactory, BIS grants the licence.
The licence includes:
BIS provides different application processing routes under Scheme-I.
The applicable route depends on the product, applicant category and BIS instructions.
Under Option 1, BIS conducts the factory assessment and arranges sample drawal for independent testing.
Foreign manufacturers generally proceed under Option 1.
The official target for completing an eligible Option 1 application may be up to 90 days from the date of receiving a complete application.
The 90-day period is conditional. It may increase if:
Option 2 is available for eligible domestic manufacturers and eligible products.
Under this route, the manufacturer normally submits acceptable test reports before the factory visit.
The target processing period may be approximately 30 days from receipt of the complete application, provided the factory visit and product conformity are satisfactory at the first instance.
For an all-India first product case, the processing target may extend to approximately 45 days.
The latest test report should generally not be more than 90 days old when submitted. Where multiple reports are used, the oldest supporting report may need to remain within approximately 180 days.
Manufacturers should not assume that Option 2 is available for every product.
The following timeline is a practical planning estimate. Actual approval depends on product complexity, testing duration and factory readiness.
| Step | Responsible Authority | Approximate Timeline | Main Requirement | Risk |
|---|---|---|---|---|
| Product and standard mapping | Manufacturer | 2-5 working days | QCO and Indian Standard review | Wrong certification route |
| Factory gap assessment | Manufacturer | 5-15 working days | Machinery and laboratory review | Inspection failure |
| Calibration and corrective action | Factory | 1-4 weeks | Valid calibration and equipment | Application delay |
| Product testing | Laboratory | 7-30 days | Representative sample | Sample failure |
| Online application | Manufacturer | 1-3 working days | Complete technical file | Portal query |
| BIS scrutiny | BIS | 5-15 working days | Document verification | Clarification delay |
| Factory inspection | BIS | Normally 1 working day | Production and testing demonstration | Repeat visit |
| Option 2 processing | BIS | Approximately 30 days | First-instance conformity | Suspension after failed sample |
| Option 1 processing | BIS | Up to approximately 90 days | Inspection and test conformity | Long testing period |
| Licence renewal | BIS | Before expiry | Production and fee records | Expiry of licence |
Manufacturers should ideally begin preparation at least 90 to 120 days before a mandatory Quality Control Order becomes effective.
Testing is one of the most important parts of ISI certification.
The product must conform to all mandatory clauses of the applicable Indian Standard.
The manufacturer should confirm that:
Testing does not end after licence grant.
The manufacturer must continue conducting internal tests according to the Scheme of Inspection and Testing.
The required frequency may be:
The actual frequency depends on the product and test requirement.
There is no single fixed cost for all ISI Mark applications.
The total cost depends on:
| Cost Component | Cost Basis |
|---|---|
| Application fee | BIS processing charge |
| Factory inspection fee | Number of inspection days |
| Product testing fee | Test parameters and laboratory |
| Annual licence fee | Generally around ₹1,000 |
| Minimum marking fee | Product-specific |
| Actual marking fee | Based on certified production |
| Renewal fee | Licence period and production |
| Scope extension fee | Additional models or varieties |
| Professional support fee | Documentation and technical preparation |
Testing charges may range from a few thousand rupees to more than ₹1 lakh, depending on product complexity.
The minimum marking fee is product-specific and may remain payable even when actual production is lower than the declared quantity.
Manufacturers should prepare a separate budget for:
An initial ISI licence may generally be granted for a period between 1 and 2 years.
After the initial period, the licence may be renewed for a period of up to 5 years, subject to satisfactory performance and payment of applicable fees.
The renewal application should normally be submitted at least 2 months before the licence expiry date.
For example, if the licence expires on 31 December, the renewal process should ideally begin before 31 October.
The manufacturer should maintain a renewal calendar covering:
Failure to renew the licence on time may interrupt production and prevent continued use of the ISI Mark.
The ISI Mark can be used only after BIS grants the licence.
The manufacturer cannot print or use the ISI Mark during the application stage.
The mark can only be used on products included in the approved licence scope.
Manufacturers must not:
The marking should normally include:
An application may be rejected if the factory does not have adequate production or testing capability.
Rejection may also occur when:
A rejected applicant may need to correct the deficiencies and submit a fresh application.
A licence may be suspended when:
Under certain Option 2 cases, failure of the verification sample may lead to immediate suspension.
The manufacturer may be required to implement corrective action and submit a fresh sample within approximately 30 days.
BIS may direct a manufacturer to stop supplying and selling non-conforming products carrying the Standard Mark.
The manufacturer may also be required to recall products already supplied in the market.
This can result in:
Unauthorised manufacture or sale of compulsory products may attract imprisonment of up to 2 years.
The financial penalty may include:
Company directors, managers and responsible officers may also face liability where the violation occurred with their consent, knowledge or negligence.
A welding electrode manufacturer continued manufacturing and storing a product covered under a mandatory Quality Control Order without holding the required BIS licence.
During enforcement action, authorities reportedly found more than 250 boxes of finished products and over 50,000 units of packaging material.
The estimated value of the material was approximately ₹10 lakh.
The company faced risk not only because finished products were available, but also because packaging material was prepared for products requiring mandatory certification.
This case study highlights 4 important compliance lessons:
Most delays are caused by technical gaps rather than the online application form.
A manufacturer may have complete company documents but still fail because the factory cannot perform a mandatory test.
Another company may have adequate machinery but submit a sample that does not represent the full product range.
Common delay factors include:
A technical pre-assessment can reduce the risk of repeated testing and repeat inspection.
Manufacturers should work backwards from the expected market launch date.
If a Quality Control Order becomes effective on 1 October, the company should not wait until September to begin testing.
A safer preparation plan may look like this:
The company should assign responsibilities to:
Certification becomes difficult when the entire process is handled by an external consultant without factory participation.
ISI Mark Certification for Manufacturers in India is not limited to obtaining a certificate.
It is a continuing system covering product design, raw material control, production, testing, marking, inspection and renewal.
Manufacturers should identify the correct Indian Standard, prepare the factory laboratory, complete representative testing and maintain product conformity throughout the licence period.
The cost of early preparation is usually lower than the risk of rejected stock, repeat testing, delayed orders, licence suspension or enforcement action.
A delay of 30 to 90 days can affect production schedules, customer contracts and working capital. A penalty can begin from ₹2 lakh and may extend up to 10 times the value of the affected goods.
Early compliance planning helps manufacturers protect market access, maintain production continuity and reduce the possibility of rejection.

Manufacturers of products covered under a mandatory Quality Control Order must obtain the applicable BIS licence before manufacturing or selling the product.
Eligible Option 2 applications may be completed in approximately 30 days. Option 1 applications may take up to approximately 90 days, provided the application, inspection and testing are satisfactory.
Factory inspection is normally required under Scheme-I. BIS verifies production machinery, laboratory equipment, quality personnel, calibration and manufacturing controls.
The initial licence may generally be valid for 1 to 2 years. Renewal may be granted for a further period of up to 5 years.
An Indian importer cannot normally obtain the manufacturing licence in its own name for a foreign-produced product. The foreign manufacturer generally applies under FMCS.
