ISI Mark vs BIS Registration: 7 Easy Differences for 2026

ISI Mark vs BIS registration comes down to one thing: the factory inspection. The ISI Mark is granted under Scheme I after product testing and a factory audit, and carries a CM/L number. BIS registration is granted under Scheme II on a laboratory test report, with no audit, and carries an R number. You rarely choose between them, because the notified product category decides. For help confirming which route applies, see our BIS Certification Services.

Where ISI Mark vs BIS registration really matters is planning. One route needs an in house laboratory at the plant, and the other does not.

Who This ISI Mark vs BIS Registration Guide Applies To

This guide is for manufacturers and importers deciding how to certify a product, and for buyers reading a supplier’s certificate. It compares the two routes across every dimension that affects cost, timing and eligibility. Deep rules for each scheme sit in separate guides. If you are weighing ISI Mark vs BIS registration for the first time, start with the comparison table below. For wider help, review our Import Export Consultancy Services.

ISI Mark vs BIS Registration in One Table

Dimension	ISI Mark, Scheme I	BIS Registration, Scheme II
Legal instrument	Licence	Registration
Mark	ISI Mark	Standard Mark
Number format	CM/L and ten digits	R and digits
Factory inspection	Required	Not required
In house laboratory	Required	Not required
Basis of grant	Testing plus factory assessment	Test report and declaration
Foreign factories	Must apply through FMCS	Apply directly under Scheme II
Typical timeline	30 to 60 days	4 to 8 weeks
Relative cost	Higher	Lower
Surveillance	Factory inspection and market samples	Market and customs samples

Everything else in ISI Mark vs BIS registration follows from one row. The factory inspection is the fork in the road.

ISI Mark vs BIS Registration: Which Route Applies to Your Product

Product family	Route
Cement, steel, pressure cookers, cylinders	ISI Mark
Household electrical appliances under their orders	ISI Mark
Footwear, furniture, hand tools under their orders	ISI Mark
Mobile phones, laptops, adaptors, power banks	BIS registration
LED lighting, luminaires, street lighting	BIS registration
CCTV, set top boxes, audio video equipment	BIS registration
Solar photovoltaic devices and inverters	BIS registration

ISI Mark vs BIS Registration: Why the Marks Are Not Interchangeable

An ISI Mark implies a factory has been assessed. A registration does not.

That is why a CM/L number carries more weight in tenders and in business to business supply. The law treats both as valid compliance.

It also explains a common mistake. A manufacturer with an R number sometimes advertises the product as ISI certified, which creates enforcement risk.

What changed in 2026: the BIS (Conformity Assessment) Amendment Regulations, 2026, notified on 25 February 2026, applied to both sides of ISI Mark vs BIS registration. Validity extended to up to five years, fees became payable annually in advance, and non payment now triggers a ninety day suspension. Scheme II was also framed around self declaration of conformity, with electronic labelling permitted for products with an integrated display.

ISI Mark vs BIS Registration: Cost and Effort Compared

Registration costs you a test report. A licence costs you a test report plus a factory that can pass an audit.

Under Scheme I you need manufacturing machinery, in house test equipment with current calibration, quality personnel and records. Building that capability is often larger than the certification cost itself.

Under Scheme II the outcome rests on the test report and the model list. Fee detail sits in BIS certification fees India.

Foreign Manufacturers Face a Split

If the product is an ISI category, the foreign factory must use FMCS. That means an Authorized Indian Representative, a Performance Bank Guarantee of USD 10,000, and an overseas inspection.

If the product is a CRS category, the foreign factory applies under Scheme II directly. The basis is the same as for an Indian factory, so ISI Mark vs BIS registration turns on the category, not on where the plant sits.

One company can therefore face a four to six month route for one product. Another of its products may take four to eight weeks. See BIS FMCS Registration.

ISI Mark vs BIS Registration: Surveillance Compared

Aspect	ISI Mark, Scheme I	BIS Registration, Scheme II
Routine oversight	Surveillance inspections at the factory	Market and customs sampling
Trigger for action	Inspection findings or complaints	Sample failure or complaint
Practical exposure	Continuous factory discipline	Production consistency against the tested sample

Registration looks lighter at application stage. It is not lighter afterwards, because a market sample can be drawn at any time.

Reading a Supplier Certificate Correctly

Buyers are shown certificates constantly, and most never read them properly. Four fields decide whether the document means anything.

• The number format. A CM/L prefix means a licence with a factory audit behind it. An R prefix means a registration on a test report.
• The factory address. The certificate covers one plant. Goods shipped from a second plant are not covered by it.
• The standard reference. Confirm the IS number, including part and section, and check it has not been superseded.
• The model list. A certificate naming one model does not extend to a variant, however similar.

Verify the number itself rather than the image. A scanned certificate proves only that a scanner was used, and the prefix settles ISI Mark vs BIS registration faster than any logo on the page.

ISI Mark vs BIS Registration Decision Table

If this is true	Then
Product is in a MeitY notified electronics or IT category	Scheme II registration
Product is in another ministry’s Quality Control Order	Scheme I ISI Mark
Factory is outside India and product is an ISI category	FMCS
Factory is outside India and product is a CRS category	Scheme II
Product appears in no live order	Certification is voluntary
You are an importer, not a manufacturer	Neither, the factory applies

That last row is the most common misconception. See BIS certification for importers in India.

Common ISI Mark vs BIS Registration Errors

• Printing an ISI Mark while holding only a registration: improper use of a Standard Mark is a contravention.
• Mixing number formats: a CM/L format shown alongside an R number confuses customs and buyers.
• Reusing a supplier’s number: the licence is not yours to display.
• Assuming a scheme never changes: categories are re notified, and a move is a fresh application.
• Assuming registration is lighter after grant: market sampling continues throughout.
• Ignoring tender wording: many tenders name the ISI Mark specifically.

Frequently Asked Questions

Q1. Is the ISI Mark the same as BIS certification?

No. The ISI Mark is one output of BIS certification. Registration under the CRS is another. Both are BIS certification.

Q2. Can I choose between the ISI Mark and BIS registration?

Generally no. In ISI Mark vs BIS registration the notified category decides the route. Where a product is voluntary, the scheme still follows the standard and product type.

Q3. Which is cheaper, ISI or CRS registration?

Registration, because it removes factory inspection and the in house laboratory requirement.

Q4. Which is faster?

Registration, typically four to eight weeks against thirty to sixty days for an ISI licence.

Q5. Does an R number allow me to print the ISI Mark?

No. The marks and the numbers are different. Using an ISI Mark without an ISI licence is a contravention.

Q6. Do both routes need annual fees now?

Yes. Following the 2026 amendment, both carry annual advance fee payment and production statement obligations.

Q7. Which one do tenders prefer?

Many tenders name the ISI Mark specifically, because it implies a factory assessment. Check the tender wording rather than assuming equivalence.

Q8. How do I confirm ISI Mark vs BIS registration for my product?

Send the product description and the HS code. The live Quality Control Order or CRS notification settles ISI Mark vs BIS registration before any test report is booked.
