BIS Certification for Welded Stainless Steel Pipes and Tubes under IS 17876:2022

BIS Certification for Welded Stainless Steel Pipes and Tubes under IS 17876:2022. Stainless steel welded pipes and tubes are widely used in engineering, oil and gas, processing plants, construction, mechanical systems and other industrial applications. Their performance depends on several factors, including the steel grade, chemical composition, welding quality, heat treatment, wall thickness and resistance to leakage.
A weak weld, incorrect grade or uneven wall thickness can affect the strength, corrosion resistance and service life of the finished product. This is why manufacturers and importers must ensure that welded stainless steel pipes and tubes meet the applicable quality requirements.
IS 17876:2022 specifies the requirements for stainless steel welded pipes and tubes intended for general services. The standard covers product classification, manufacturing methods, chemical composition, heat treatment, mechanical properties, leak-tightness, dimensions, marking and other quality requirements.
Understanding IS 17876:2022
The complete title of the standard is “Stainless Steel Welded Pipes and Tubes for General Services Specification.”
It applies to welded stainless steel pipes and tubes used for general-service applications. Products manufactured for specialised purposes and already covered by a separate Indian Standard do not fall within this standard.
IS 17876:2022 covers four broad categories of stainless steel:

Ferritic stainless steel

Martensitic stainless steel

Austenitic stainless steel

Duplex stainless steel

The standard includes several commonly used grades, such as 201, 304, 304L, 316, 316L, 410, 430, 904L, 2205 and 2507, along with other specified grades.
The manufacturing process is identified as:

WLD: Welded

HCW: Heavily cold-worked welded, wherever applicable

The licence scope normally records the steel grade, manufacturing process, pipe nominal bore or tube outside diameter, wall-thickness range and number of seams for large pipes.
Important Product-Coverage Point
Clauses 3.1 and 3.2 define both pipes and tubes as hollow products having a round cross-section. Therefore, square and rectangular hollow sections should not automatically be treated as products covered under IS 17876:2022. Their applicable standard should be separately verified before filing a BIS application.
Is BIS Certification Mandatory?
Yes. Stainless steel welded pipes and tubes covered under IS 17876:2022 are regulated under the Stainless Steel Pipes and Tubes (Quality Control) Order, 2025, issued by the Department for Promotion of Industry and Internal Trade.
The mandatory implementation date specified for stainless steel welded pipes and tubes was 1 August 2025. From the applicable date, covered products must conform to IS 17876:2022 and bear the BIS Standard Mark under a valid Scheme-I licence.
The QCO does not apply to:

Goods manufactured domestically exclusively for export.

Up to 500 kg of goods imported by stainless steel pipe and tube manufacturers each year for research and development, subject to prescribed conditions, including no commercial sale and proper record-keeping.

The Ministry of Steel also issued a temporary shipment-based import exemption for specified ITC-HS codes, including 73053190, 73053990 and 73064000, where the Bill of Lading showed a shipped-on-board date on or before 30 June 2026. This was a transitional exemption and should not be treated as a continuing exemption for later shipments.
Who Needs BIS Certification?
The BIS licence is primarily granted to the actual manufacturing unit.
An Indian manufacturer producing covered welded stainless steel pipes or tubes must obtain a Scheme-I licence for its factory. A foreign manufacturer supplying these products to India must obtain a licence under the Foreign Manufacturers Certification Scheme.
An importer, trader, distributor or brand owner generally cannot obtain the manufacturing licence merely because it sells or imports the product. It must source the goods from a manufacturing unit holding a valid BIS licence covering the relevant grade, process and size.
A separate application is generally required for each manufacturing location. However, one licence may cover multiple grades, sizes or varieties when permitted by the standard and the applicable grouping guidelines.

Important Test Conditions
The hardness test is not required for tubes smaller than 6.4 mm OD or having wall thickness below 0.51 mm. Such tubes are subjected to tensile testing. Small tubes with OD from 1.27 mm to 12.7 mm and wall thickness from 0.13 mm to 1.65 mm need not undergo the flanging test.
For tubes above 150 mm OD or with wall thickness of 9.52 mm and above, flattening may be performed instead of flanging. Tubes above 203 mm OD or with wall thickness of at least 9.52 mm are treated as large-size tubes for the flattening requirement. All finished pipes and tubes must undergo hydrostatic leak-tightness testing, and the test pressure must be held for at least five seconds and long enough to inspect the product.
Sample Quantity and Testing Requirements
The BIS Product Manual specifies a sample length of 2.5 metres for independent testing. The exact number of samples depends on the proposed licence scope. Under the grouping guidelines, samples are selected to cover combinations of minimum and maximum nominal bore or outside diameter and wall thickness for the relevant grade group and manufacturing process.
A manufacturer applying for both WLD and HCW varieties may therefore need separate samples for each applicable process. Where several grades and size ranges are proposed, the final sample plan should be confirmed before sending material to the laboratory. Complete samples must be long enough to prepare tensile, hardness, flanging, flattening, reverse-flattening, chemical and metallographic specimens. Hydrostatic testing also requires a suitable finished product rather than only a small cut section.
Documents Required for BIS Certification
Indian Manufacturers
Commonly required documents include:

Business registration and factory details

Factory ownership, lease or possession documents

Manufacturing-process flow chart

Factory layout and location plan

List of manufacturing machinery

List of testing equipment

Conducting a factory and testing-facility gap assessment.

Installing and calibrating the necessary testing equipment.

Preparing the technical and legal documents.

Filing the Scheme-I application with BIS.

BIS factory assessment of manufacturing and quality-control facilities.

Factory testing and selection or sealing of samples.

Independent testing through a laboratory accepted by BIS.

Resolution of any technical observations or non-conformities.

Grant of licence with an approved product scope.

Use of the Standard Mark and CM/L number only on products covered by the licence.

BIS grants a licence after successfully assessing the manufacturing infrastructure, production process, quality control, testing capability and product conformity. Foreign-manufacturer cases are handled under FMCS.
Factory Testing Facilities
The Product Manual provides an indicative list of equipment that may be required, including:

Spectrometer or chemical-analysis facilities

Vernier calipers, micrometers, steel scales and measuring tapes

Universal tensile-testing machine with extensometer

Brinell and Rockwell hardness testers

Flanging and flattening-test equipment

Metallurgical microscope and specimen-preparation equipment

Hydrostatic-testing arrangement

Corrosion-testing equipment, where applicable

Straightedge for workmanship and straightness checks

The factory must maintain a laboratory with suitable equipment and trained personnel, follow a calibration plan and retain test records. Under the Product Manual, subcontracting is permitted only where specifically allowed and through a BIS-recognised or government laboratory accepted by BIS.
Marking Requirements
Under Clause 25, each pipe or tube must be marked with:

Manufacturer’s name and trademark

Nominal bore and thickness for pipes

Outside diameter and thickness for tubes

Grade

Heat number

Lot number

Process, namely WLD or HCW

After certification, the Standard Mark and BIS licence number must also be applied in the manner approved by BIS. The ISI Mark cannot be used before the licence is granted or on varieties outside the approved scope.
Common Reasons for Delay or Rejection
Applications may face difficulty due to an incorrect product scope, insufficient testing facilities, absence of qualified technical personnel, product failure, incomplete calibration, mismatch between declared and actual machinery, unavailable samples or delayed corrective action.
Technical preparation is especially important because the proposed sizes and grades must be supported by suitable manufacturing capability, testing arrangements and conforming samples.
Official Scheme-I guidelines allow rejection where samples are not offered, repeated sample failure occurs, testing facilities or technical personnel are unavailable, major deviations are found during inspection or the applicant does not address observations within the permitted period.
Consequences of Non-Compliance
After implementation of the QCO, covered products cannot ordinarily be manufactured, imported, distributed, sold, stored or displayed for sale without conformity to the applicable standard and a valid BIS Standard Mark.
Violation may result in enforcement action, restrictions on sale or import, seizure of non-compliant goods, suspension or cancellation of an existing licence and penalties under the BIS Act, 2016.
