A number of strict minimum standards must be met by manufacturers in order to receive ISI Certification. These specifications form the cornerstone of an effective certification procedure and guarantee product quality, safety, and conformity with Indian Standards. It is quite important that you comprehend them before you start the process. For your thorough knowledge, below is a complete explanation to the requirements for ISI Certification.
-
Production Site:
Make sure your production plant follows the Indian Standard's recommended quality control procedures.
-
Testing Facility:
Determine if some tests require cooperation with outside testing laboratories or if you have testing facilities on-site.
-
Procedures for Quality Control:
In your manufacturing process, establish and record all procedures for quality control.
-
Product Compliance:
Check to see whether your product meets the Indian Standard's performance requirements and technical specifications.
-
Factory Inspection:
Ascertain that your facility, along with the required staff, equipment, and infrastructure, is prepared for a factory inspection by BIS authorities.
-
Calibration of Testing Equipment:
Ensure that every testing equipment in your establishment is accurately calibrated and satisfies the necessary accuracy requirements. Ensuring reliable testing findings is crucial for the ISI Certification process.
-
Keeping Record:
Maintaining test results, quality control protocols, product specifications, and other information requires the establishment of an orderly record-keeping system.
Difference Between ISI and BIS
These two terms get used all the time interchangeably, and that mix-up is worth clearing up properly:
| |
ISI Mark
|
BIS
|
|
What it is
|
A specific certification mark
|
The regulatory body that issues it
|
|
Full form
|
Indian Standards Institute
|
Bureau of Indian Standards
|
|
Scope
|
One certification scheme (Scheme-I) among several BIS runs
|
Governs all schemes: ISI, CRS, FMCS, Scheme-X, Hallmarking
|
|
History
|
India's original standards body, founded in 1947
|
BIS Act, 2016, reconstituted the same authority with wider powers
|
|
Basis of approval
|
Factory audit + lab testing + ongoing surveillance
|
Varies by scheme (self-declaration for CRS, audit-based for ISI/FMCS/Scheme-X)
|
BIS ISI mark certification is what most people mean when they say "BIS certified," but BIS itself runs several schemes, and ISI is just one of the schemes built around a physical factory audit rather than a paperwork-only declaration.
Timeline, Cost, Validity and Renewal
Below, we have discussed the timeline, cost, validity, and renewal:
Timeline:
|
Procedure
|
Duration
|
|
Simplified Procedure
|
35–40 days
|
|
Normal Procedure
|
60–65 days
|
|
Foreign manufacturers (FMCS route)
|
4–8 months
|
Domestic manufacturers who already have testing infrastructure and clean documentation in place tend to land closer to the Simplified Procedure timeline; first-time applicants and those needing to build lab capability often take the longer route.
Cost: ISI mark certification cost is made up of a few separate pieces rather than one flat fee:
-
BIS application fee, paid at submission
-
Product testing charges at a BIS-recognised laboratory
-
Factory audit and inspection charges
-
Annual license/marking fee, payable once certification is granted
The total varies by product category, the number of models covered, and whether in-house testing equipment already meets BIS's expectations or needs to be added first. A product-specific quote from an ISI mark certification consultant is the most reliable way to budget accurately.
Validity: An ISI license is generally granted for one year from the date it's issued. Some product categories carry different terms as specified in their applicable Indian Standard, so it's worth checking the specific IS code a product falls under.
Renewal: File the renewal application, along with the required documents and fees, within 90 days before the one-year term ends. Renewal doesn't usually require a fresh factory audit, though BIS may conduct a surveillance visit as part of the process. Renewed terms can run up to five years at a time, though many manufacturers still prefer annual renewal simply to stay flexible as standards and regulations evolve.
