BIS Certification for Stainless Steel Pipes and Tubes Under IS 17875 & IS 17876
By Standphill India | BIS Certification Consultants | Updated: 2026 Category: BIS Certification | FMCS | Stainless Steel | Success Story
Stainless steel pipes and tubes sold in India must meet BIS certification requirements under IS 17875 : 2022 (Seamless) and IS 17876 : 2022 (Welded). In this article, we explain the complete BIS certification process for stainless steel pipes and tubes — what these standards cover, which grades and sizes are included, what documents you need, and how the FMCS process works for foreign manufacturers. We also share how Standphill India successfully helped HYG CO., LTD — a South Korea-based stainless steel manufacturer — obtain BIS FMCS certification for both welded and seamless stainless steel pipes and tubes in India.
Introduction - Why BIS Certification Matters for Stainless Steel Pipes and Tubes
India is one of the fastest-growing infrastructure markets in the world. Construction projects, industrial plants, oil and gas pipelines, food processing facilities, pharmaceutical manufacturing units, and chemical plants — all of them use stainless steel pipes and tubes extensively. And as India's demand for high-quality stainless steel products grows, so does the government's focus on ensuring that the products entering the market — whether manufactured domestically or imported from abroad — meet strict quality and safety standards.
That is exactly where BIS certification comes in.
If you are a manufacturer or importer of stainless steel pipes and tubes in India, BIS certification is not optional. It is a legal requirement. Without it, your products cannot be legally sold in India — not in retail, not on e-commerce platforms, and not through government contracts or tenders.
For Indian manufacturers, this certification happens through the standard BIS ISI Mark licensing process. For foreign manufacturers — companies based in South Korea, China, Germany, Taiwan, Japan, or anywhere else in the world — this certification happens through a specific BIS pathway called the Foreign Manufacturers Certification Scheme (FMCS).
In this article, we are going to break down everything you need to know about BIS certification for stainless steel pipes and tubes — and we will also share a real success story of how Standphill India helped HYG CO., LTD, a South Korea-based manufacturer, successfully obtain BIS FMCS certification for two product categories in India.
What is BIS Certification?
Before we get into the specifics of stainless steel pipe certification, let's quickly cover what BIS certification actually is for anyone who is new to this.
BIS stands for Bureau of Indian Standards — India's official national body that sets quality and safety benchmarks for products sold in India. Every product category that requires mandatory certification has an Indian Standard (IS) number assigned to it. This IS number refers to a detailed technical document that defines exactly what a product must do, how it must be made, what tests it must pass, and what quality levels it must consistently meet.
When a product receives BIS certification, it means it has been independently tested and verified against the relevant Indian Standard. The BIS certification number must be displayed on the product before it can legally enter the Indian market.
For stainless steel pipes and tubes, there are two key Indian Standards:
• IS 17875 : 2022 — for Stainless Steel Seamless Pipes and Tubes for General Services
- IS 17876 : 2022 — for Stainless Steel Welded Pipes and Tubes for General Services
Both of these standards are relatively recent — they were updated in 2022 — and they define the technical requirements, dimensional tolerances, material grades, mechanical properties, and test parameters that stainless steel pipes and tubes must meet to be sold in India.

• Stainless Steel Welded Pipes and Tubes for General Service (IS 17876:2022)
- Stainless Steel Seamless Pipes and Tubes for General Service (IS 17875:2022)
IS 17876 : 2022 - BIS Certification for Stainless Steel Welded Pipes and Tubes
What is IS 17876 : 2022?
IS 17876 : 2022 is India's official standard for stainless steel welded pipes and tubes for general services. Welded pipes and tubes are manufactured by forming a strip or sheet of stainless steel into a tube shape and then welding the seam — a process known as WLD (Welded). This is a widely used manufacturing method that produces pipes suitable for a broad range of industrial and commercial applications.
Which Steel Grades are Covered?
IS 17876 : 2022 covers the following austenitic stainless steel grades:
• Grade 304 — also designated as X04Cr19Ni9
- Grade 304L — also designated as X02Cr19Ni10
- Grade 316 — also designated as X04Cr17Ni12Mo2
- Grade 316L — also designated as X02Cr17Ni12Mo2
These are among the most widely used stainless steel grades globally. Grade 304 and 304L are known for their excellent corrosion resistance and general-purpose versatility. Grade 316 and 316L offer superior resistance to chloride corrosion and are preferred for more demanding environments like marine applications, chemical processing, and food-grade use.
What Sizes are Covered?
Under IS 17876 : 2022, the certified size range for welded tubes covers:
• Outside Diameter (OD): 12.7mm to 152.40mm
- Wall Thickness: 0.89mm to 3.00mm
This is a broad and commercially significant size range — covering everything from small-diameter precision tubes to larger industrial pipes used in structural and process piping applications.
What Tests are Required?
The standard specifies several mechanical, dimensional, and chemical tests. For the HYG CO., LTD certification specifically, the scope covers products without Transverse Tension Test (Cl.11), Corrosion Test (Cl.19), and other tests (Cl.20) as specified in IS 17876 : 2022.
IS 17875 : 2022 - BIS Certification for Stainless Steel Seamless Pipes and Tubes
What is IS 17875 : 2022?
IS 17875 : 2022 is India's official standard for stainless steel seamless pipes and tubes for general services. Unlike welded pipes, seamless pipes and tubes have no weld seam — they are manufactured from a solid billet of steel that is pierced and drawn into a tubular shape. This gives seamless pipes superior pressure-bearing capability and a more uniform structure, making them preferred for high-pressure, high-temperature, and precision applications.
HYG CO., LTD's seamless pipes and tubes are cold finished — meaning they undergo a cold working process after the initial forming. Cold finishing gives the tubes a precise surface finish, tighter dimensional tolerances, improved mechanical properties, and a cleaner, smoother exterior. This makes cold-finished seamless tubes particularly suitable for applications where dimensional accuracy and surface quality matter.
Which Steel Grades are Covered?
IS 17875 : 2022 covers the same four high-quality austenitic stainless steel grades:
• Grade 304 — also designated as X04Cr19Ni9
- Grade 304L — also designated as X02Cr19Ni10
- Grade 316 — also designated as X04Cr17Ni12Mo2
- Grade 316L — also designated as X02Cr17Ni12Mo2
What Sizes are Covered?
The certified size range for seamless tubes under IS 17875 : 2022 covers:
• Outside Diameter (OD): 6.35mm to 25.4mm
- Wall Thickness: 0.89mm to 2.11mm
This is a precision size range — smaller diameter, tighter tolerances — perfectly suited for instrumentation tubing, heat exchangers, precision mechanical components, and other applications where exact dimensions are critical.
What Tests are Required?
For the HYG CO., LTD certification, the scope covers products without Transverse Tension Test (Cl.11), Corrosion Test (Cl.18), and other tests (Cl.19) as per IS 17875 : 2022.
What is BIS FMCS? — The Certification Path for Foreign Manufacturers
Since HYG CO., LTD is based in South Korea, they could not apply for standard BIS ISI Mark certification — that route is only available to manufacturers with production facilities in India. Instead, they applied through FMCS — the Foreign Manufacturers Certification Scheme.
FMCS is BIS's official pathway that allows manufacturers based outside India to obtain BIS certification for products they want to export and sell in the Indian market. It is the most internationally relevant of all BIS schemes, and it is the route that every serious foreign manufacturer must go through if they want legal access to India's market.
Here is what makes FMCS different from standard domestic BIS certification and why it requires extra planning and preparation.
Authorized Indian Representative (AIR)
Every FMCS applicant must appoint an Authorized Indian Representative (AIR). This is a legal entity or individual based in India who acts as the official point of contact between the foreign manufacturer and BIS. The AIR accepts legal responsibility for the certified products in the Indian market, communicates with BIS on behalf of the manufacturer, and ensures ongoing compliance after certification is granted.
Choosing the right AIR is important. The AIR needs to be reliable, accessible, and capable of handling BIS communications professionally. In many cases, a BIS certification consultant like Standphill India serves as or recommends the appropriate AIR.
Overseas Factory Audit
This is the aspect of FMCS that most foreign manufacturers find most challenging. Unlike CRS registration (which is lab-report based), FMCS requires a physical factory audit at the overseas manufacturing facility by BIS officials.
BIS inspectors travel to your factory — in this case, to South Korea — and conduct a detailed inspection of your manufacturing infrastructure, quality control systems, equipment, personnel, and production records. They want to verify that your factory is genuinely capable of consistently producing products to the quality levels claimed in your application.
The cost of the BIS officials' travel and stay during this audit is borne entirely by the applicant — which is one reason why FMCS has a higher overall cost than domestic BIS certification. But for manufacturers who are serious about the Indian market, this investment is absolutely worth it.
Product Testing
Products must be tested at a BIS-approved, NABL-accredited laboratory. The test reports must cover all the parameters specified in the relevant Indian Standard — in this case, IS 17875 and IS 17876. BIS does not accept test reports from laboratories that are not on their approved list.
The Complete BIS FMCS Certification Process — Step by Step
Whether you are a stainless steel pipe manufacturer or any other type of product manufacturer outside India, the FMCS process follows these key steps:
Step 1 — Product Assessment and IS Identification
Identify the exact Indian Standard that applies to your product. For stainless steel welded pipes, that is IS 17876 : 2022. For seamless pipes, that is IS 17875 : 2022. Confirm that your product's grades, dimensions, and specifications fall within the scope of the standard.
Step 2 — Appoint an Authorized Indian Representative (AIR)
Before any application can be submitted, you must formally appoint an AIR in India. This appointment must be documented through an official letter and power of attorney.
Step 3 — Product Testing at a BIS-Approved Laboratory
Send representative product samples to a BIS-approved, NABL-accredited laboratory for testing against all applicable parameters of IS 17875 or IS 17876. Ensure test reports are comprehensive, clearly formatted, and valid.
Step 4 — Prepare and Compile Application Documents
Gather and prepare all required documentation — company registration, factory details, product specifications, manufacturing process details, quality system documents, machinery lists, and personnel details. Every document must be accurate, complete, and consistent with what BIS will verify during the factory audit.
Step 5 — Submit Application on the BIS Portal
Submit the complete FMCS application online through the official BIS portal (manakonline.in) along with all documents and the prescribed application fees.
Step 6 — BIS Document Scrutiny and Query Response
BIS officers review the application in detail. They may raise queries for clarification or additional information. All queries must be responded to promptly and accurately to keep the application moving forward.
Step 7 — Overseas Factory Audit by BIS Officials
BIS inspectors travel to your manufacturing facility for a physical audit. They verify your factory infrastructure, machinery, quality systems, and production capabilities. Thorough preparation for this audit is critical.
Step 8 — Grant of BIS FMCS Certificate
After successful document scrutiny and factory audit, BIS grants the FMCS certificate. Your products are now officially authorized for sale in India.
Step 9 — Ongoing Compliance — Surveillance and Renewal
FMCS certification requires ongoing compliance. BIS conducts periodic surveillance checks, and the certificate must be renewed at the appropriate time. Staying on top of these obligations is essential to maintaining your market access.
Documents Required for BIS FMCS Certification
Here is a comprehensive list of the documents typically required for an FMCS application for stainless steel pipes and tubes:
Company Documents
Business registration certificate of the overseas company, proof of legal existence and ownership structure, bank account details, and address proof of the registered office.
AIR Documents
Authorized Indian Representative appointment letter, power of attorney granting the AIR authority to act on behalf of the overseas manufacturer before BIS, and AIR's identity and address proof in India.
Factory and Infrastructure Documents
Factory address proof, complete factory layout plan showing all production areas, storage, quality control lab, and testing areas. List of all manufacturing machinery and equipment with technical specifications and capacity details.
