If you’re producing or importing V-belts especially endless narrow V-belts for industrial use, then listen up. In India, these products fall under a specific Indian Standard IS 14261:1995 and you can’t just sell them without the Bureau of Indian Standards (BIS) ISI mark registration as they are notified under the compulsory scheme.
Before you think this is just another label, let me explain clearly why this matters, exactly what the standard is about, who must register, and how to go about it.
V-belts are essential components in machinery. They transfer power between shafts and pulleys in equipment such as:
When we say endless narrow V-belts, we mean belts that have no seams they are continuous loops. They are thin, designed for higher speed and tighter spaces, and carry power in industrial applications where reliability matters.
IS 14261:1995 is the Indian Standard that defines how these belts should be made and tested. It talks about:
These norms exist because V-belts need to be reliable under load. The standard is not about marketing or branding. It is about technical safety and performance.
BIS ISI Mark Registration for Telescopic Ball Bearing Drawer Slide IS 17954:2023
Getting the ISI mark registration is evidence that:
The ISI mark is not just a logo sticker. It is a legal certification issued by BIS under the brand–licence scheme.
This requirement applies to you if you are:
If you are just a reseller of another company’s brand, then you must check if that brand already has valid BIS registration for these products.
For imported products, the brand or manufacturer outside India must appoint an Authorised Indian Representative (AIR) to obtain the BIS licence on their behalf.
BIS ISI Certificate for Stainless Steel Vacuum Flask or Bottle: IS 17526
I’m going to break this down into clear stages so it doesn’t feel overwhelming.
Don’t guess the standard. This one is IS 14261:1995 specifically for endless narrow V-belts for industrial use.
If you classify under a wrong code, BIS simply won’t accept your application. They will return it as “non-compliant classification.”
Be precise.
You must get representative samples tested in a BIS-recognised laboratory. That’s not optional.
The lab will test:
Test reports from recognised labs are mandatory for the BIS submission.
Send units that reflect your normal production quality. Don’t send one good piece and call it a day. BIS looks for consistency in manufacturing.
Your BIS application should include:
Match details across all documents. If your model number on the lab report doesn’t match what you submit in the form, BIS can reject or delay.
Consistency matters.
BIS has an online portal.
You will:
Take care with uploads. Incorrect file formats or unclear file names cause unnecessary delays.
BIS often checks files manually after the first submission. If something is missing or unclear, they will ask for clarification.
Reply promptly.
Leaving queries unanswered only delays your certification.
When everything is in order, BIS issues your registration certificate. It will list specific product models and the ISI mark licence number.
Now you can use the ISI mark on your belts and on packaging. That’s your legal pass mark.
Getting your BIS ISI Mark registration for telescopic V-belts (endless narrow V-belts) under IS 14261:1995 is not optional if you want to sell legally in India. Yes, it takes time testing, paperwork, responses, rechecks but it protects you and your customers.
