BIS Certification for Polypropylene Fibre Ropes IS 5175:2022

BIS Certification for Polypropylene Fibre Ropes | IS 5175:2022 | 3, 4, 8 & 12 Strand Ropes |

Introduction

Polypropylene fibre ropes are widely used in marine operations, agriculture, construction, transportation, fishing, logistics, industrial applications and other general-purpose uses. Their performance depends on factors such as the polypropylene material, rope construction, linear density, diameter and minimum breaking strength.

To establish conformity of specified polypropylene fibre ropes with Indian requirements, IS 5175:2022 provides the applicable technical requirements.

The standard is titled Fibre Ropes – Polypropylene Split Film, Monofilament and Multifilament (PP2) and Polypropylene High-Tenacity Multifilament (PP3) – 3-, 4-, 8- and 12-Strand Ropes. It is aligned with ISO 1346:2021.

The product is also covered under the Ropes and Cordages (Quality Control) Order, 2024, under which the specified goods must conform to the corresponding Indian Standard and bear the Standard Mark under a BIS licence in accordance with Scheme-I. The QCO came into force on 1 April 2025, with a separate commencement date of 1 July 2025 for Small and Micro Enterprises for domestic production. The Order does not apply to goods meant for export.

For manufacturers, exporters, importers and overseas companies supplying these ropes to India, understanding the BIS certification requirements before commercial production or import is therefore important.

What is IS 5175:2022?

IS 5175:2022 is the fourth revision of the Indian Standard for specified polypropylene fibre ropes.

The standard covers ropes made from:

Polypropylene split film
Polypropylene monofilament
Polypropylene multifilament
Polypropylene high-tenacity multifilament

The standard identifies PP2 and PP3 material categories and covers four principal rope constructions:

Type A – 3-strand hawser-laid rope
Type B – 4-strand shroud-laid rope
Type L – 8-strand braided rope
Type T – 12-strand braided rope

It also specifies requirements relating to designation, general requirements, linear density and minimum breaking strength.

Is BIS Certification Mandatory for Polypropylene Fibre Ropes?

Yes, specified polypropylene fibre ropes are covered under the Ropes and Cordages (Quality Control) Order, 2024.

The QCO includes Fibre ropes – Polypropylene split film, monofilament and multifilament (PP2) and polypropylene high-tenacity multifilament (PP3) – 3-, 4-, 8- and 12-strand ropes, corresponding to IS 5175:2022. The QCO requires conformity to the Indian Standard and the use of the Standard Mark under a BIS licence under Scheme-I.

Implementation Dates

For the Ropes and Cordages QCO:

1 April 2025: General commencement.
1 July 2025: Commencement for Small and Micro Enterprises for domestic production.

These dates are specified in the 2024 QCO.

A later amendment issued on 5 June 2026 created a temporary exemption concerning goods specified at serial number 7 that are made out of recycled plastic waste, for twelve months from publication of that amendment. Manufacturers dealing with such products should verify the precise applicability of this exemption before relying on it.

What Does the BIS ISI Mark Mean for Polypropylene Ropes?

The BIS Standard Mark, commonly referred to as the ISI Mark, is used under a valid BIS licence and indicates conformity with the applicable Indian Standard within the approved certification scope.

For covered polypropylene fibre ropes, manufacturers should not treat the ISI Mark as a general quality logo. The product must be covered by an appropriate BIS licence, and the marking must comply with the licence conditions.

The BIS Scheme-I listing currently includes IS 5175:2022 under Ropes and Cordages compulsory certification.

Which Polypropylene Ropes Are Covered?

IS 5175:2022 covers the specified polypropylene fibre ropes manufactured using PP2 and PP3 materials and four strand constructions.

3-Strand Polypropylene Rope

Type A is a 3-strand hawser-laid rope.

4-Strand Polypropylene Rope

Type B is a 4-strand shroud-laid rope.

8-Strand Polypropylene Rope

Type L is an 8-strand braided rope.

12-Strand Polypropylene Rope

Type T is a 12-strand braided rope.

These four constructions are expressly identified in the BIS Product Manual and current BIS laboratory scope.

PP2 and PP3 Polypropylene Fibre Ropes

The standard distinguishes between different polypropylene material categories.

PP2 covers polypropylene split film, monofilament and multifilament rope materials.

PP3 covers polypropylene high-tenacity multifilament.

The applicable material category should be correctly identified before testing and preparation of the BIS certification scope.

A manufacturer should not assume that certification for one material category automatically covers every other polypropylene material category.

Rope Types Under IS 5175:2022

The BIS Product Manual identifies the licence scope using Type A/B/L/T, corresponding to the four constructions. It also identifies size using the applicable reference number, which corresponds approximately to rope diameter. The material and termination configuration are also relevant to the licence scope.

Therefore, manufacturers should prepare their product range carefully before beginning testing.

Unspliced and Eye-Spliced Polypropylene Ropes

The BIS Product Manual identifies both:

Unspliced ropes
Ropes with eye-spliced terminations

as relevant scope parameters.

The proposed licence scope should therefore clearly identify which varieties the manufacturer intends to cover.

Key Requirements Under IS 5175:2022

The standard addresses several important characteristics of polypropylene fibre ropes.

General Requirements

The rope must comply with the applicable general requirements relating to its construction, constituent materials, treatment and other characteristics.

Current BIS LIMS testing scopes include checks associated with general requirements and rope construction.

Construction and Manufacture

The construction of the rope must correspond to the applicable rope type.

This includes the arrangement and construction of the strands and yarns used to manufacture the rope.

Lay or Pitch

The applicable pitch or length of lay is an identified requirement.

BIS LIMS currently lists pitch or length-of-lay testing for IS 5175:2022.

Linear Density

Linear density is an important physical characteristic specified under the standard.

The BIS LIMS scope identifies linear-density testing under the relevant tables of IS 5175:2022.

Minimum Breaking Strength

The standard specifies minimum breaking strength requirements for the applicable rope type, material and reference number.

This is one of the key performance characteristics evaluated during testing.

Marking and Labelling

The standard contains marking and labelling requirements, and current BIS laboratory scopes identify applicable marking and labelling checks.

Important BIS Tests for Polypropylene Fibre Ropes

Testing is an essential part of BIS certification.

Depending on the product configuration and applicable scope, testing may include:

Material identification
General requirements
Construction and structure
Rope type
Pitch or length of lay
Diameter/reference number
Linear density
Minimum breaking force
Workmanship
Treatment
Marking and labelling
Packaging and delivery-length requirements

Current BIS LIMS records show these types of testing parameters for IS 5175:2022.

Diameter and Reference Number

The BIS Product Manual identifies reference number as an important part of the certification scope, with the reference number corresponding approximately to rope diameter.

The manufacturer therefore needs to identify the reference numbers of the ropes intended to be covered by the BIS licence.

Linear Density Testing

Linear density is tested according to the applicable requirements of IS 5175:2022.

Current BIS LIMS listings include linear-density testing for the relevant tables covering polypropylene rope types.

The result must meet the applicable nominal value and tolerance requirements for the selected rope construction and reference number.

Minimum Breaking Force Testing

Minimum breaking force is one of the most important performance parameters for fibre ropes.

The test establishes whether the rope can meet the minimum breaking-force requirement corresponding to its applicable type, material and reference number.

Current BIS LIMS listings specifically identify Minimum Breaking Force testing under Clause 6 and the relevant tables of IS 5175:2022.

UV Treatment and Stabilization

Polypropylene ropes may require suitable treatment or stabilization for their intended service conditions.

The BIS laboratory scope identifies testing/checks associated with UV inhibitor/stabilizer identification as part of the applicable general requirements in some laboratory testing packages.

Manufacturers should ensure that the material formulation and treatment used in production are consistent with the requirements applicable to their certified product.

BIS Testing Charges for IS 5175:2022

Testing charges are not one fixed amount for every manufacturer.

They depend on:

Laboratory
Rope type
Material category
Reference number
Testing scope
Applicable parameters
Number of varieties being evaluated

Current BIS LIMS listings show different testing packages. For example, one current listing shows ₹9,600 excluding taxes for an indicated testing scope, while another laboratory lists ₹7,250 excluding taxes and other current laboratory entries show different amounts.

Another current BIS laboratory scope lists a testing package of approximately ₹14,900 excluding taxes for IS 5175:2022.

Therefore, manufacturers should obtain the applicable laboratory quotation after finalizing the proposed BIS product scope.

BIS Product Sampling and Grouping

The grouping and sampling strategy is particularly important for polypropylene ropes because the standard covers multiple materials, constructions, reference numbers and termination configurations.

The BIS Product Manual specifies scope parameters including:

Type A/B/L/T
Reference number
Material
Unspliced ropes
Eye-spliced termination ropes

The Product Manual states that the licence scope is to be established using these product characteristics.

Manufacturers should therefore avoid selecting samples randomly without first preparing a complete product-scope matrix.

Can One Sample Cover Multiple Rope Sizes?

The applicable grouping provisions should be reviewed carefully.

The earlier BIS grouping guidance for this product family established that testing a higher reference number could allow coverage of lower reference numbers, subject to the applicable manufacturing and testing facilities. The revised Product Manual should be followed for current applications.

Therefore, manufacturers should have the current BIS Product Manual reviewed before finalizing their sample-selection plan.

BIS Factory Inspection for Polypropylene Rope Manufacturers

Because the product is covered under Scheme-I, BIS certification involves assessment of the manufacturer's manufacturing infrastructure, process controls, quality-control system and testing capabilities.

BIS explains that certification involves assessment of manufacturing infrastructure, process controls, quality control and testing capabilities, together with establishing product conformity through applicable testing.

During factory assessment, manufacturers should be prepared for evaluation of:

Raw-material storage
Polypropylene yarn/fibre control
Rope-making machinery
Twisting/braiding equipment
Treatment facilities
Cutting and coiling facilities
Testing equipment
Calibration records
Quality-control procedures
Finished-product inspection
Product identification
Batch records
Internal testing
Marking arrangements

Manufacturing Process for Polypropylene Fibre Ropes

The manufacturing process can vary depending on the rope type and material.

A typical manufacturing operation may involve:

Raw Material → Yarn/Fibre Preparation → Treatment/Stabilization → Strand Formation → Twisting/Braiding → Rope Formation → Finishing → Cutting/Coiling → Inspection & Testing → Packing

The actual process must be appropriate for the rope construction and conform to the requirements applicable to the manufacturer's certified product.

Scheme of Inspection and Testing

The Scheme of Inspection and Testing (SIT) is an important part of BIS certification.

The BIS Product Manual for IS 5175:2022 refers to the applicable Scheme of Inspection and Testing and testing-equipment requirements.

The manufacturer should maintain appropriate controls for:

Incoming raw materials
Production
Rope construction
Linear density
Breaking force
Dimensions/reference number
Marking
Finished-product inspection
Calibration
Non-conforming products
Records and traceability

Documents Required for BIS Certification

A manufacturer applying for BIS certification for polypropylene fibre ropes may need:

Company registration documents
Factory address details
Manufacturing process flow
Factory layout
Machinery list
Testing-equipment list
Calibration certificates
Raw-material specifications
Supplier documents
Product specifications
Rope construction details
PP2/PP3 material details
Reference-number/size details
Internal test reports
Quality-control procedures
Technical personnel details
BIS application documents
Brand/trademark documents, where applicable
Undertakings and declarations required by BIS

The exact documentation should be confirmed according to the current BIS application procedure and the manufacturer's specific circumstances.

BIS Certification Process for Polypropylene Fibre Ropes

Step 1: Identify the Applicable Standard

Confirm that the product falls under IS 5175:2022.

Step 2: Prepare the Product Range

List all:

PP2 products
PP3 products
3-strand ropes
4-strand ropes
8-strand ropes
12-strand ropes
Reference numbers
Unspliced ropes
Eye-spliced ropes

Step 3: Determine the Certification Scope

Review the current BIS Product Manual and grouping provisions to determine representative samples and proposed licence varieties.

Step 4: Review Factory Facilities

Check whether the factory has the required manufacturing machinery, testing equipment and quality-control arrangements.

Step 5: Conduct Product Testing

Samples are tested against the applicable requirements of IS 5175:2022 through the appropriate BIS-recognized testing route.

Step 6: Prepare and Submit BIS Application

The manufacturer submits the application and supporting documents through the applicable BIS certification process.

Step 7: Factory Assessment

BIS assesses the manufacturing facility and verifies production and quality-control arrangements.

Step 8: Address Non-Conformities

Any non-conformity identified during testing or assessment must be addressed according to the applicable BIS procedure.

Step 9: BIS Licence Grant

After successful completion of the applicable requirements, BIS may grant the licence for the approved product scope.

Step 10: ISI Marking

The manufacturer may use the BIS Standard Mark according to the licence conditions and approved scope.

BIS Certification for Foreign Manufacturers

The Ropes and Cordages QCO applies to specified goods supplied in India, while the QCO itself excludes goods meant for export.

Therefore, an overseas manufacturer producing polypropylene ropes exclusively for export outside India is not brought within this particular QCO merely because the product conforms to IS 5175:2022.

However, an international manufacturer exporting polypropylene fibre ropes to India needs to consider BIS certification because the product is covered under compulsory certification for the Indian market.

BIS operates the Foreign Manufacturers Certification Scheme (FMCS) for eligible foreign manufacturers. BIS states that FMCS provides a route for a foreign manufacturer to obtain a BIS licence for products conforming to an Indian Standard.

BIS FMCS for Overseas Polypropylene Rope Manufacturers

Foreign manufacturers supplying IS 5175:2022 polypropylene ropes to India can require BIS certification under FMCS, subject to the applicable requirements.

This is relevant for manufacturers located in:

China
Vietnam
Thailand
Indonesia
Taiwan
South Korea
Japan
Germany
Italy
Turkey
United Arab Emirates
United Kingdom
United States
Other countries exporting polypropylene ropes to India

BIS requires a foreign applicant to nominate an Authorized Indian Representative (AIR) as part of the FMCS process.

BIS also states that, from 1 June 2026, FMCS applications are accepted only through the online portal rather than offline/hard-copy submission.

BIS Certification for Imported Polypropylene Ropes

Importers should understand that purchasing polypropylene ropes from an overseas supplier does not itself replace the manufacturer's BIS certification obligations where a QCO applies.

BIS's FMCS FAQ explains that for products covered by compulsory certification, imports into India require the applicable Standard Mark under a valid BIS licence.

For this reason, international manufacturers planning to supply polypropylene ropes to India should review BIS requirements before shipping commercial consignments.

Can an Importer Apply for the BIS Licence?

Under FMCS, the application is made by the foreign manufacturer, not simply by an importer acting on behalf of the manufacturer. BIS's FMCS FAQ specifically states that an importer cannot apply for the licence on behalf of the foreign manufacturer.

This is an important point for international suppliers and Indian importers planning a new product launch.

Common Reasons for BIS Certification Delays

Manufacturers may face delays because of:

Incorrect product classification
Incomplete product range
Incorrect reference numbers
Wrong grouping strategy
Inadequate testing facilities
Missing calibration certificates
Incomplete raw-material records
Non-conforming breaking-force results
Incorrect linear-density results
Incomplete marking arrangements
Missing quality-control records
Unprepared factory inspection
Incomplete BIS application documents

For foreign manufacturers, additional issues can include:

AIR documentation
Incomplete FMCS documents
Factory inspection coordination
Sample transportation
Testing arrangements in India
Delays in responding to BIS queries

Proper preparation before application can reduce avoidable delays.
