Understanding the CRGO Supply Gap in India
India has faced a persistent CRGO supply gap through 2024–2025. This situation makes compliance and sourcing efficiency critical. According to BusinessWorld and GTRI, the demand for Cold-Rolled Grain-Oriented (CRGO) steel is on the rise, especially in the power sector.
CRGO used in transformer cores must comply with IS 3024:2015 under the Steel & Steel Products (Quality Control) Order, 2020. BIS marking and licensing (or CoC) is mandatory. You can find more details in the Internet Archive.
Chennai: A Hub for CRGO Steel Trade
Chennai remains a strategic trading location. Its proximity to Chennai Port and Kamarajar (Ennore) Port enhances logistics for imports and domestic distribution. The dedicated Sathangadu Iron & Steel Market (203 acres) streamlines these processes. This market is crucial for traders and buyers alike, making it easier to access quality materials. More information can be found on Wikipedia, IBEF, and the Chennai Municipal Corporation.
The Growing Demand for CRGO Steel
Downstream demand is supported by India’s growing transformer market. New core-processing capacity additions in 2025 will further drive this demand. According to GlobeNewswire and Transformer Magazine, the market is expected to grow significantly.
Why CRGO Matters—and Where Chennai Fits
CRGO (Cold-Rolled Grain-Oriented electrical steel) is engineered for optimal performance. Its magnetic domains align in the rolling direction, which reduces core losses in transformers. India’s transformer build-out and grid modernization have kept CRGO in high demand. Multiple analyses through late-2024 estimate that India required ~400,000 tonnes of CRGO in FY 2024, with only ~50,000 tonnes produced domestically. This shortfall is primarily met through imports, as highlighted by BusinessWorld.
Chennai is one of the country’s most efficient places to trade electrical steels due to several factors:
Blue-water access: Chennai Port (INMAA) handles iron & steel among its major cargoes. Kamarajar Port (Ennore), located just north of the city, serves bulk and break-bulk streams.
A purpose-built market yard: The Sathangadu Iron & Steel Market spans approximately 203 acres and connects to ports and railheads. This concentration of steel traders in one zone enhances efficiency.
For CRGO buyers and OEMs, this combination reduces lead time from berth to shop floor and improves access to testing, slitting, and lamination services through local partners.
Compliance: BIS & IS 3024:2015—Non-Negotiable in 2025
Under India’s Steel & Steel Products (Quality Control) Order, 2020, CRGO sheet and strip must meet IS 3024:2015 and carry the BIS Standard Mark under license or a Certificate of Conformity. Authorities have reinforced QCO coverage and enforcement windows over 2020–2025. Practically, this means:
Import consignments without BIS compliance (or applicable exemptions) risk clearance delays.
OEM audits increasingly require documentary proof, including license/CoC, mill TC, and traceability to IS 3024 grades.
If you specify by IS 3024 designations (e.g., 23CG110, etc.), you align with the Indian standard’s grade system for core loss and thickness ranges. Always keep your MTCs, BIS license numbers, and batch traceability ready for tenders.
Demand Drivers (2024–2025): Why Availability Still Feels Tight
Transformer CAPEX & replacements: India’s power and distribution transformer market is growing. Recent reports peg the 2025 value at ~$4.5 billion, with a CAGR in the mid-single digits to 2031. This growth pulls steady volumes of CRGO grades for distribution and power transformer cores.
New core-processing capacity: In 2025, Toshiba TTDI inaugurated a CRGO core processing centre (12,000 t/yr). This move signals that OEMs are localizing steps like slitting, stacking, and annealing, which supports regional demand in South India.
Import-dependent reality: With domestic CRGO output limited compared to need, buyers must stay sharp on import lead times, documentation, and port logistics. Public import dashboards and trade data sites show CRGO shipments entering India across major ports through 2024–2025.
Import Routes & Chennai Logistics (Buyer Notes)
Ports: CRGO often enters via the west coast (JNPT/Nhava Sheva), but Chennai/Kamarajar are key for South-bound supply. Chennai Port lists iron & steel among major imports, with its 2023–24 throughput surpassing 51.6 million tonnes across cargo types.
Market access: The Sathangadu Iron & Steel Market provides traders and OEM buyers quick access to multiple stockists in one ecosystem. Public listings show numerous steel businesses operating inside the market. Always verify CRGO-specific capability and BIS documentation.
Quality and Grades: What to Ask Your Supplier
Standard: Ensure compliance with IS 3024:2015 (BIS), equivalent to global GOES conventions. Insist on BIS license/CoC particulars on documents.
Grade & core loss: Specify by IS grade (e.g., 23CG110) and maximum W/kg at test flux (per IS 3024 tables). Mill TCs should state thickness, coating type, Epstein test results, and lot traceability.
Processing history: For lamination sheets (mitered, step-lap, V-notch), confirm whether strips were slit locally and whether stress-relief anneal is needed for your build spec (distribution vs. power transformer).
Market Realities (2024–2025) to Budget For
Structural shortfall: Analyses in late-2024 highlight a ~350 kt gap between demand and domestic production. This gap periodically tightens availability and keeps grade-wise pricing sensitive to global cycles.
Policy & compliance friction: Ongoing QCO expansions and BIS tightening mean non-compliant shipments face more scrutiny. Plan for documentation buffers.
Trade flows: India’s broader steel imports (not CRGO specifically) surged in FY 2025. Authorities even weighed safeguards on certain categories. While CRGO is a niche within HS 72, overall customs vigilance can still affect lead times.
Chennai Buyer’s Checklist (S M STEELS’ Perspective)
Ask for IS 3024:2015 proof: Ensure you receive the BIS license/CoC along with the MTC, which should include grade, loss values, and coating details.
Verify origin & routing: Confirm the port of discharge (Chennai/Ennore vs. JNPT) to estimate inland freight and delivery windows.
Plan around demand cycles: Coordinate orders before peak tender seasons for utilities to avoid grade shortages (e.g., 23CG110 in thin gauges).
Local processing partners: For laminations (mitered, V-notch, gapping), align with a processor that can meet your stacking factor and burr specs. Ensure they provide anneal certification where required. Capacity expansion news from OEMs signals more local options in 2025.
About Sathangadu, Chennai—Why This Market Yard Helps
The Chennai Metropolitan Development Authority (CMDA) describes the Sathangadu Iron & Steel Market as ~203 acres, strategically located close to Chennai Port and railheads. This makes it an ideal aggregation point for import lots, secondary sheets, and scrap movement. Public listings show multiple wholesalers operating inside the complex. For buyers, this density means better grade discovery and faster truck turnarounds.
