Introduction At S M Steels , we’ve noticed a significant decline in CRGO (Cold Rolled Grain Oriented) steel prices and demand across India as of September 2025. This downturn raises important questions for many businesses: Why is this happening now? Is this a temporary situation? What should we expect next? In this blog, we will analyze factual, up-to-date data and trends that contribute to the current market dip. Understanding these factors will empower you to make smarter purchasing or inventory decisions during these uncertain times. The Current Market Landscape What the Data Shows Imports are Falling Sharply In August 2025, steel imports into India declined by approximately 31% . SteelOrbis Simultaneously, exports rose by about 54% , although India remains a net steel importer. SteelOrbis Policy and Regulation Tightening for Steel Input Quality The Indian government has introduced stricter rules requiring imported input materials (slabs, billets, etc.) to comply with BIS (Bureau of Indian Standards) norms, not just the finished product. Argus Media These regulations reduce import flexibility and can delay shipments or increase costs for non-compliant imports. Argus Media Weak Demand and Seasonal Slowdown The monsoon period in India traditionally slows construction activity, which softens demand for steel products (flat/coil sheets, HRC, etc.). Policy Circle+1 Domestic industries such as construction, infrastructure, and consumer appliances—major users of transformer cores—are experiencing slower order inflow. Leads are not converting into purchases as quickly. Policy Circle Pressure from Cheap Imports, Especially Chinese Steel Steel from China, sold at discounted prices, has entered the Indian market, pushing down local pricing. Reuters+2Policy Circle+2 Indian steel mills are advocating for safeguard measures (temporary taxes or duties) to counter these imports. Reuters+2Policy Circle+2 Margins Under Pressure for Steel Producers Falling prices for Hot Rolled Coils (HRC) and other steel inputs are squeezing margins. Input costs (iron ore, coal, etc.) remain high while selling prices slide. The Times of India+3Policy Circle+3Reuters+3 Since CRGO is a specialized steel grade, the impact is magnified by the added costs of production, quality testing, and import constraints. The Impact on CRGO Steel CRGO, being a specialty steel material for transformers and electrical applications, experiences the effects of the above factors more acutely: There is reduced demand from industries that rely on stable, long-term procurement (power utilities, transformer manufacturers). They become cautious amid price volatility and policy changes. Import delays or higher costs for CRGO inputs due to new quality control rules (BIS compliance) can lead to non-compliant shipments being rejected or delayed. Suppliers may cut prices or offer discounts to move inventory, lowering market price benchmarks for CRGO materials (coils, laminations). Buyers are postponing purchases, expecting prices to fall further, which weakens spot demand. Implications for Buyers and Distributors If you are a buyer of CRGO steel (transformer manufacturer, distributor, etc.), or a seller like S M Steels, here are some practical implications and strategies: | Situation | Implication | Suggested Action | |------------------------------------------------|--------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------| | Declining CRGO spot prices | You may be able to negotiate better purchase terms or delay procurement if you have flexibility. | Lock in favorable quotes now for future deliveries; consider buying in smaller lots to reduce risk. | | Uncertain import quality / delays | Risk of paying for non-compliant material or having your project delayed. | Always verify BIS-certified suppliers; request documentation; do sample testing. | | Market oversupply & buyer caution | Leads may drop; some buyers may delay orders. | Maintain strong relationships with clients; offer flexible payment or delivery terms; highlight quality/durability advantages. | | Margins squeezed for suppliers | Profit margins may reduce; inventory holding costs rise. | Reduce holding costs; optimize stock; try sourcing from lower import cost channels that meet quality; highlight cost-per-performance to buyers. | Outlook: What to Watch Next To predict when the CRGO market might recover or stabilize, keep an eye on these indicators: Policy Updates — Monitor any final decisions on safeguard duties, new import-quality rules, or tax changes on steel imports. Import Data — Track monthly and quarterly steel import/export volumes. A sustained drop in cheap imports could ease pressure. Infrastructure & Transformer Tenders — Watch for government investment in power, grid upgrades, EV charging, and renewable integration. New transformer orders will drive CRGO demand. Raw Material Cost Moves — Keep an eye on costs of silicon steel inputs, electricity, and steel-making energy. If those drop, cost pressure eases. Seasonal Demand Changes — Post-monsoon and winter months usually see a pickup in construction and industrial activity. Conclusion The current downturn in the CRGO steel market is driven by a mix of import pressure, regulatory tightening, seasonal demand softening, and falling steel input prices . While some of these factors are short-term (monsoon, seasonal lag), others (policy, imports) are structural and likely to shape the market for months ahead. For businesses involved in CRGO—both buyers and suppliers—it’s a time for caution, smart negotiation, rigorous quality control, and flexible procurement strategies. At S M Steels , we are closely monitoring these trends, ensuring that our CRGO coil and lamination supplies meet the required standards, and offering steady reliability despite market volatility.

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.
