BIS Certification for Steel Wire Suspension Ropes for Lifts, Elevators & Hoists

Every time an elevator door closes, the people inside are trusting a handful of steel wire ropes they will never see. Elevator suspension ropes live a uniquely punishing life: they bend over the traction sheave thousands of times a day, every day, for years - so unlike a crane rope, which is sized around breaking force, an elevator rope is engineered and tested around fatigue endurance and dimensional discipline. IS 2365:2018 is the standard that governs this product, and India's high-rise construction boom is exactly why it was pulled under compulsory certification.

Diameter tolerance matters here in a way outsiders rarely appreciate: the rope must sit in the sheave groove with precisely the right contact, and a set of ropes on one car must share load evenly - which is why elevator ropes are made to closer, more consistent tolerances than general engineering rope, and why global elevator OEMs audit their rope suppliers so hard. The ISI Mark is now the legal entry ticket to that market in India.

Knowing exactly where your product sits within the standard saves time and money at the testing stage. The practical scope:

The vertical-transport backbone of urban India:

Testing reflects the rope's real enemy - repeated bending, not a single overload:

This order is strict on exemptions. There is essentially one exemption: goods manufactured domestically purely for export. There is no exemption for goods imported as a component of a finished product, and no small-unit turnover exemption - Micro and Small Enterprises were only given later compliance dates (1 June 2025 and 1 March 2025 respectively), and both of those dates have now passed. Today the order applies with full force to every manufacturer, of every size, selling into India.

BIS expects documentation in three broad groups. Getting the format right is the single biggest cause of delay for first-time applicants, which is exactly the part we take off your plate:

• Administrative: company registration, factory licence, trademark proof, and - for foreign makers - the Authorized Indian Representative appointment.
• Technical: product drawings and construction details, raw-material details (rope cores and wires are themselves checked against their own standards), machinery list, in-house test equipment list, and the recognised-lab test report.
• Quality control: the quality manual, competent QC personnel details, and the process and quality-control flow for the product.

The route depends on where your factory is. Indian manufacturers follow the domestic Scheme-I process - sample testing, documentation and a factory assessment before the licence is granted (official standard timeframe is about 30 days for a fully-prepared file; realistically plan for a few weeks to a few months). The step-by-step is on our BIS Certification for Indian Manufacturers page. Manufacturers outside India go through FMCS with an Authorized Indian Representative and typically an overseas factory audit (standard timeframe about 180 days) - see our FMCS guide.

Once the licence is granted, BIS issues a unique licence number (the CM/L number). The ISI Mark together with that CM/L number must be applied to the product and its packaging in the manner the standard prescribes - for ropes this typically travels with the reel/coil tag and test certificate that buyers and inspectors check. Selling a notified product that carries no mark, or a mark without a valid licence behind it, is treated as non-compliance.

The Bureau of Indian Standards is the certifying and enforcing authority for this product, and non-compliance is dealt with under the BIS Act, 2016:

• Seizure of stock from the factory, warehouse or distribution chain.
• Customs detention of imported consignments that arrive without a valid licence and marking.
• Fines and imprisonment as provided under the BIS Act, 2016 - for a first offence, imprisonment up to two years or a fine of at least two lakh rupees, rising steeply for repeat offences.
• Loss of tenders and contracts - mining houses, elevator OEMs, oil companies, utilities and infrastructure EPCs require the ISI Mark as a precondition.

This order spans nine very different products - crane ropes, elevator ropes, mine ropes, oil-well lines, stay strand, a nylon life-safety rope, barbed wire and gabion mesh - each under its own Indian Standard with its own test regime, and several tied to safety-critical, regulator-watched industries. We work across the entire order as specialists, prepare every document to exact BIS format, and coordinate lab testing and the factory assessment so your file keeps moving - whether your plant is in India or overseas.
