Why US Oil & Gas Companies Source Forgings from India
American oil and gas procurement teams are increasingly sourcing forged components from India — not as a cost-cutting measure of last resort, but as a deliberate supply chain strategy driven by quality, certification depth, and the structural advantages that Indian forge-to-finish manufacturers have built over four decades. The question for US buyers is no longer whether Indian forging manufacturers can meet API 20B, ASME, and NACE MR0175 requirements — several can and do. The question is how to identify which Indian manufacturers operate at the quality level that US oil and gas programmes require, and what the practical sourcing process looks like.

The Structural Shift in US Oil & Gas Forging Procurement
US oil and gas operators — ExxonMobil, Chevron, BP, Shell, ConocoPhillips — and their EPC contractors have been diversifying their forging supply chains since 2020. The reasons are both strategic and economic.
Supply chain concentration risk became visible.
The COVID-19 disruptions of 2020–2022 demonstrated that dependence on a small number of domestic or single-region suppliers creates programme risk. When a US Gulf of Mexico deepwater project requires 200 duplex valve body forgings on a critical path and the primary domestic supplier has a 22-week backlog, the project stalls. Operators who had pre-qualified alternative international suppliers — including Indian API 20B certified manufacturers — maintained schedule continuity.
Reshoring economics changed the calculation.
The US forging industry’s domestic capacity is heavily weighted toward high-volume automotive and commercial applications. Critical oil and gas forgings — complex geometries in duplex stainless, super duplex, and Inconel, in quantities of 10–100 units — are not the natural production volume that drives US forge shop economics. For these high-mix low-volume requirements, US domestic pricing reflects the setup cost of a forge shop optimised for different production models.
Indian manufacturers invested in the right certifications.
The meaningful change in the last decade is not that Indian forging manufacturers became cheaper — they already were. The change is that established Indian manufacturers pursued and maintained API 20B, AS9100D, ABS, and IBR certifications, built NABL-accredited in-house testing laboratories, established working relationships with internationally recognised third-party inspection companies, and built quality systems that can pass Saudi Aramco SAMSS-012 audits. A supplier that meets Aramco’s requirements meets any US operator’s requirements.
What Has Changed in the Last 10 Years
Certification Infrastructure
Ten years ago, the number of Indian forging manufacturers holding current API 20B licenses covering PSL 3 and PSL 4 with demonstrated duplex and CRA capability was very small. Today, established Indian manufacturers hold the full certification stack — API 20B (PSL 1–4), AS9100D, ABS, IBR, and NABL-accredited testing — that US oil and gas procurement requires.
The API product directory allows any US buyer to verify an Indian manufacturer’s API 20B license instantly. The license number, the covered PSL levels, the material scope, and the expiry date are all publicly verifiable. This removes the opacity that once made international forging sourcing risky.
Third-Party Inspection Presence
Bureau Veritas, DNV GL, SGS, Intertek, and Lloyd’s Register all have established operations in India’s major forging manufacturing centres — Bangalore, Pune, Rajkot, and Hosur. A US operator requiring Bureau Veritas or DNV witness inspection on every lot can specify this as a standard purchase order requirement, and Indian manufacturers with established TPI relationships will have the inspection company on-site within the agreed notification window.
This is structurally equivalent to TPI on a domestic US order. The inspection certificate from Bureau Veritas India carries the same authority as one from Bureau Veritas Houston.
Documentation Standards
Indian manufacturers who have invested in international oil and gas supply understand that documentation is not a box-checking exercise — it is the product. A US procurement team receiving a forging from India with an incomplete MTR, a heat treatment chart that shows a temperature excursion without formal disposition, or a CoC that references a superseded specification revision has a documentation problem that is indistinguishable from a quality problem until the investigation is complete.
Established Indian API 20B manufacturers now produce documentation packages — MTR, independent chemical analysis, mechanical test report, heat treatment record with furnace chart, UT and MT/PT reports, dimensional inspection report, PMI results, and CoC — that meet SAMSS-012 and equivalent demanding documentation standards. These packages are formatted for international review.
The Cost Advantage: What It Actually Means
The cost advantage of Indian API 20B forging versus domestic US supply is real but often mischaracterised. The typical range is 25–45% lower landed cost for equivalent specification forgings — after accounting for ocean freight, marine insurance, customs clearance (duty rates on steel forgings to the USA are typically 0% under most trade classifications for oil and gas equipment), and the domestic logistics cost from port to the EPC contractor’s fabrication yard.
What the cost advantage is not:
It is not a discount on quality.
An API 20B forging from an Indian manufacturer meets the same specification as one from a US manufacturer. The specification is the specification — the API license is verified the same way, the PSL level is the same, the material requirements are the same. Cost reduction comes from lower manufacturing overhead, not from specification compromise.
It is not consistent across all forging categories.
For standard carbon steel flanges in commodity sizes — ASME B16.5 Class 150–600 in ASTM A105 — domestic US supply is heavily competitive and the Indian cost advantage narrows significantly after all logistics costs. The Indian advantage is most pronounced in complex geometries, CRA material grades (duplex, super duplex, Inconel), and high-mix low-volume programmes where the domestic US cost structure is less efficient.
It is not guaranteed on every order.
Steel raw material prices fluctuate globally. A strong rupee narrows the cost differential. The meaningful cost advantage comes from the combination of lower labour costs, lower overhead, and the manufacturing efficiency of a forge shop oriented toward high-mix critical components rather than high-volume commercial production.
The Lead Time Reality
US buyers who ask about lead times from India receive answers that range from 8 weeks to 20 weeks — and both can be accurate for the same type of forging depending on the manufacturer’s current order book and the specific material and specification.
For standard carbon steel oil and gas forgings — ASTM A105 flanges, AISI 4130 valve bodies, ASTM A350 LF2 low-temperature components — established Indian manufacturers can typically produce and ship within 10–14 weeks from order placement. This includes forging, heat treatment, testing, TPI, documentation, and ocean freight to a US Gulf Coast port.
For CRA forgings in duplex 2205 or super duplex 2507 — where raw material procurement from Sandvik or Outokumpu adds 4–6 weeks to the front of the manufacturing schedule — the realistic total lead time is 14–20 weeks.
Compared to domestic US supply: US forge shops for equivalent CRA components in equivalent quantities typically quote 8–14 weeks ex-works. Adding domestic logistics from the forge shop to the fabrication yard brings total delivery comparable to the Indian landed timeline. For commodity carbon steel standard sizes, domestic US supply is faster. For complex CRA in moderate quantities, the timelines are comparable.
The practical implication for US procurement: Indian forging sourcing works well when it is planned into the project schedule from the outset — not when it is used as an emergency alternative after domestic supply fails. Procurement teams who include Indian API 20B manufacturers in their bid lists from the beginning of project procurement planning — treating them as qualified alternates alongside domestic suppliers — get the benefit of competitive pricing and supply chain diversity without schedule risk.
Where the Indian Advantage Is Strongest
Complex CRA Forgings in Moderate Quantities
Duplex 2205 and super duplex 2507 valve bodies, flanges, and pressure housings in quantities of 10–100 units represent the sweet spot of Indian forging supply for US oil and gas. This is where Indian manufacturers’ high-mix low-volume capability, combined with 25–40% cost advantage over equivalent domestic US CRA forging supply, creates the most compelling procurement case.
Inconel and Nickel Alloy Forgings for HPHT Applications
Inconel 625 and 718 forgings for High Pressure High Temperature well applications — choke bodies, HPHT tree structural components, downhole tool pressure housings — are a category where established Indian manufacturers with demonstrated Inconel forging history, double-ageing heat treatment capability, and ASNT Level II immersion UT qualification compete directly with the small number of US and European specialists in this material.
API 6A Wellhead and Christmas Tree Forgings
4130 and 4130M alloy steel forgings for API 6A wellhead equipment — gate valve bodies, master valve bodies, wing valves — are a high-volume category for US Gulf of Mexico and US onshore operations. Indian API 20B manufacturers with demonstrated 4130M production history, NACE MR0175 sour service capability including SSC and HIC testing, and established TPI relationships are competitive for this category.
Large Diameter Pressure Vessel Nozzle Forgings
Open die forgings for pressure vessel nozzles — ASTM A182 F22 alloy steel or F316L stainless in the 500–5,000 kg range — are produced on large hydraulic presses that are more common in India’s established forge shops than in the US’s current industrial base, which has seen significant consolidation of large press capacity. Indian manufacturers with 3,000+ tonne press capacity and documented large-section open die forging capability have a genuine advantage in this category.
Addressing the Concerns US Buyers Raise
“How do I know the quality is real?”
Verify the API 20B license in the API product directory — takes 2 minutes. Confirm NABL accreditation for the test laboratory. Review the manufacturer’s TPI track record — which companies have conducted witness inspections and on what programmes. Request a sample documentation package from a recent lot in the relevant material. Ask for the last SAMSS or ADNOC supplier audit report if available — these are the most rigorous audits in the industry, and a manufacturer who has passed one has been verified to a standard that exceeds most US operator requirements.
“What happens if there’s a quality problem?”
The same thing that happens with a domestic US supplier — a corrective action request, containment, root cause investigation. For Indian suppliers, the practical challenge is the 9,000-mile distance from the US buyer to the Indian forge shop. This is why pre-qualification — including an on-site capability assessment visit before the first order — and establishing TPI as a standard requirement on every lot are important. TPI does not eliminate quality problems but it does provide an independent verification layer at the source that catches conformance issues before the forgings leave India.
“Can they handle urgent requirements?”
Honestly — less well than domestic US supply for true emergencies. If a platform is down and replacement forgings are needed in 2 weeks, Indian supply is not the answer. Indian supply works for planned procurement, not emergency response. US procurement teams who use Indian suppliers effectively plan this into their supply chain strategy — building up to 3-month safety stock for critical components sourced from India, treating Indian supply as the primary for planned procurement and maintaining a domestic US emergency source for unplanned urgent requirements.
“What about ITAR?”
ITAR (International Traffic in Arms Regulations) governs the export of defence-related articles and services. For oil and gas forgings — pressure-retaining components, structural fittings, valve bodies — ITAR does not typically apply. Standard API 20B oil and gas forgings are not ITAR-controlled items. Import of these forgings from India is a standard commercial import transaction. The ITAR question becomes relevant for dual-use items — forgings that could be used in both commercial oil and gas and military applications. For straightforward oil and gas pressure-retaining components, ITAR is not a barrier.
How the Sourcing Process Actually Works
The US buyer who wants to begin sourcing forgings from India follows a sequence that is simpler than it appears from the outside:
Step 1: Identify Indian API 20B certified manufacturers via the API product directory. Filter by PSL level, material scope, and product type.
Step 2: Request capability information — API 20B license copy, AS9100D certificate with scope, NABL accreditation certificate, recent MTRs in the relevant material grade, TPI track record summary. Allow 5 working days for a complete response from a well-organised manufacturer.
Step 3: Conduct a technical review of the capability information. For a significant programme, plan a site visit — typically 2–3 days in Bangalore or Hosur to conduct an on-site assessment.
Step 4: Place a qualification order — typically 2–5 components with full documentation package and TPI witness inspection. Review the documentation package and TPI certificate on receipt.
Step 5: If qualification is satisfactory, issue a framework purchase agreement or long-term supply agreement covering pricing, lead times, TPI requirements, documentation standards, and payment terms.
Step 6: Plan Indian supply into project procurement schedules as a qualified alternate or preferred source for the relevant forging categories.

Frequently Asked Questions – US Oil & Gas Companies Sourcing Forgings from India
What API 20B PSL levels do Indian forging manufacturers typically hold?
Established Indian API 20B manufacturers hold licenses covering PSL 1 through PSL 3 for most material families. PSL 4 — the most demanding level, requiring HIC and SSC testing per NACE TM0284 and TM0177 — is held by a smaller number of Indian manufacturers. US buyers sourcing subsea and sour service forgings at PSL 4 should specifically verify PSL 4 coverage on the manufacturer’s license before proceeding with qualification. The API product directory shows PSL levels explicitly for each licensed manufacturer.
Are there any US import duties on forged steel components from India?
For most oil and gas forging categories — carbon steel flanges, alloy steel valve bodies, stainless and duplex pressure fittings — the US import duty rate is 0% under the Harmonised Tariff Schedule classifications applicable to industrial forged components for pressure equipment. Anti-dumping duties that apply to some steel products (certain pipe and tube categories, for example) do not typically apply to custom-manufactured forgings for oil and gas applications. US customs brokers familiar with industrial equipment imports can confirm the applicable HTS codes and duty rates for specific forging categories before an order is placed.
Can Indian forging manufacturers supply to Saudi Aramco approved vendor list projects where Aramco specifies US Gulf of Mexico operations?
Saudi Aramco’s SAMSS-012 supplementary requirements apply to Aramco’s own procurement globally — including for Aramco’s US assets and joint ventures. An Indian manufacturer on Aramco’s approved vendor list can supply to any Aramco-controlled programme worldwide. For non-Aramco US Gulf of Mexico operator projects, the operator’s own vendor qualification requirements apply — typically API 20B with operator-specific supplementary requirements. Being on Aramco’s AVL provides strong evidence of quality system maturity and is referenced favourably by other operators during their own vendor assessments.
What is the typical payment term for importing forgings from India to the USA?
For initial orders with a new Indian forging supplier, US buyers typically use an irrevocable Letter of Credit (LC) against shipping documents — standard international trade practice for capital goods. This protects both parties: the seller is guaranteed payment against compliant documents, and the buyer is guaranteed shipment of conforming goods before payment is released. For established supply relationships, Documentary Collection (D/P terms) or open account terms are negotiated based on the supplier’s track record and the buyer’s credit management policy.
How should US oil and gas procurement teams structure a qualification visit to an Indian forging manufacturer?
A 2–3 day on-site qualification visit to an Indian forging manufacturer for oil and gas supply typically covers: Day 1 — quality management system review (AS9100D compliance documentation, NCR log, internal audit records, TPI coordination procedure), Day 2 — shop floor assessment (press capacity demonstration, heat treatment area including furnace calibration records, NDT area including UT and MT equipment and operator certifications, test laboratory), Day 3 — documentation review (representative lot documentation package, MTR filing system, traceability live test). The most productive visits occur when the buyer prepares a specific checklist aligned with their purchase order requirements and reviews it systematically rather than conducting a general tour.
