Most analysis of India's CRGO gap looks upstream, at the steelmakers, the technology, the JV structures, the policy instruments. This article looks downstream, at the transformer manufacturers who consume CRGO and convert it into the grid equipment that India's infrastructure programmes require. Their perspective is different, and their problems are immediate.
India's transformer industry includes publicly listed companies, CG Power, Hitachi Energy India, Transformers and Rectifiers India (TRIL), Voltamp Transformers, Bharat Bijlee, alongside public-sector BHEL and Siemens Energy India. Together they form the third-largest transformer market in the world, serving utilities (state DISCOMs, Power Grid Corporation), industrial customers, and export markets.
For all of them, CRGO is the single most critical input material. It constitutes 30 to 40% of a transformer's material cost. And every one of them faces the same five supply-side problems.
Where procurement goes wrong
1. BIS certification friction
The Bureau of Indian Standards Quality Control Order for IS 3024 makes BIS certification mandatory for all CRGO sold in India, imported and domestic. Foreign mills must be registered with BIS before their material can enter the Indian market. The certification process takes months, requires factory inspections (often in China, Japan, Korea, or Russia), and must be periodically renewed. A mill that loses its certification cannot supply India until it is restored.
The BIS requirement creates supply gaps that transformer manufacturers cannot predict. If a mill loses its certification (or if a new supplier has not yet completed registration) the transformer maker must either find an alternative source (often at a premium) or delay production. For Hi-B and domain-refined grades, where the global supplier base is three to six companies, a BIS disruption at one source can mean that no certified alternative exists.
The intent of BIS certification is quality assurance, ensuring that all CRGO sold in India meets IS 3024:2015 specifications. The effect, however, is also trade friction: it adds time and cost to imports, tilting the playing field toward domestic supply. When domestic supply covers 10% of the market, this tilt lands on the 90% that must be imported.
2. Foreign exchange exposure
CRGO is priced in US dollars on global markets. Indian transformer manufacturers sell to domestic utilities in Indian rupees, with contracts often fixed at bid time. The gap between CRGO purchase (USD) and transformer sale (INR) can be months, long enough for currency movements to erode margins. A 5% INR depreciation against USD on a CRGO bill of Rs 100 crore costs Rs 5 crore, often with no contractual mechanism to pass it through.
The FX exposure is structural, not hedgeable in practice for mid-size transformer makers. Large companies can use forward contracts or natural hedges (export revenue in USD). Smaller manufacturers absorb the currency risk directly. In periods of rupee weakness (such as during global risk-off episodes or oil-price spikes) CRGO procurement costs rise even when international CRGO prices are flat.
3. Hi-B and domain-refined grade scarcity
As transformer efficiency norms tighten under IS 1180 and the BEE labelling framework, the market is moving from conventional CGO toward Hi-B grades. Hi-B delivers 15-20% lower core losses than conventional CGO, and domain-refined delivers a further 5-15% improvement. But Hi-B is made by five to six companies globally, and domain-refined by three to four. No Indian producer makes either grade.
Transformer manufacturers bidding on contracts that specify low-loss cores must source Hi-B or domain-refined CRGO internationally, from Nippon Steel, JFE, POSCO, thyssenkrupp, or Cleveland-Cliffs. Lead times for these grades are longer (12 to 20 weeks), pricing is less transparent, and allocation can be constrained when global demand peaks. If anti-dumping duties are imposed on GOES from Japan and Korea (the primary Hi-B sources) the landed cost of these grades rises with no domestic alternative.
4. Inventory and working capital burden
CRGO procurement from international suppliers involves 12 to 20-week lead times (order placement to delivery at the transformer factory). Transformer makers must carry three to six months of CRGO inventory to maintain production continuity. At Rs 80,000 to Rs 1,50,000 per tonne (depending on grade), this represents a working capital commitment of Rs 50 to 200 crore for a mid-size manufacturer.
The inventory burden is compounded by uncertainty. If a BIS certification lapses for a preferred source, or if a shipment is delayed by port congestion or customs clearance, the buffer evaporates quickly. Domestic supply from JSW JFE, with shorter lead times and rupee-denominated pricing, would ease the working capital burden, but at 50,000 tonnes against 400,000+ tonnes of demand, domestic supply does not yet offer meaningful procurement diversification for most transformer makers.
5. Anti-dumping uncertainty
The DGTR investigation initiated on 22 June 2026 targets CRGO imports from all four source countries simultaneously. If anti-dumping duties are imposed, the landed cost of imported CRGO rises by an estimated 15 to 25%. This cost increase lands directly on transformer manufacturers, who must either absorb it (lower margins) or pass it to utilities (higher transformer prices, higher grid costs).
The uncertainty itself is damaging, even before duties are imposed. Transformer manufacturers bidding on contracts with 12 to 18-month delivery timelines cannot price CRGO procurement risk accurately if they do not know whether duties will be imposed, at what level, and for which grades. Some manufacturers have reported adding contingency margins to bids to cover the duty risk, making their bids less competitive against international transformer suppliers (from China, Korea, or Turkey) who procure CRGO without the duty burden.
Now add the grid expansion
These five problems exist against the backdrop of the largest grid expansion programme in India's history. The numbers define the scale of transformer demand that the industry must deliver.
The grid expansion is not optional. It is a prerequisite for absorbing 500 GW of renewable capacity, electrifying transport, and meeting industrial load growth. The transformer industry must deliver this capacity. And virtually every transformer it delivers needs CRGO in its core.
The collision between grid ambition and CRGO supply constraint is the central tension in India's electrical infrastructure planning. The grid cannot wait for domestic CRGO capacity to scale. But trade protection on imported CRGO raises costs for the very transformers the grid expansion requires.
Transformer makers want three things
From the transformer manufacturer's perspective, the ideal CRGO supply picture has three characteristics: multiple qualified sources (for procurement risk diversification), competitive pricing (for bid competitiveness), and grade availability (for meeting efficiency specifications).
India's current CRGO supply situation delivers none of these:
| Need | Current Reality | Impact |
|---|---|---|
| Multiple qualified sources | 1 domestic, 4 import countries (all under AD investigation) | Concentration risk; no fallback if any source disrupted |
| Competitive pricing | USD-denominated imports; potential AD duties | FX risk + duty risk = margin compression |
| Grade availability | Hi-B and domain-refined. 100% imported | Cannot meet highest-efficiency specs with domestic CRGO |
| Predictable lead times | 12-20 weeks international; BIS disruptions | High inventory carry; production planning uncertainty |
Policy, from the downstream seat
The transformer industry's requirements from CRGO policy are specific and distinct from the steelmaker's requirements. Where JSW JFE needs market protection to justify its Rs 5,845 crore expansion, transformer manufacturers need supply security and cost predictability to deliver the grid expansion pipeline.
2026 to 2028, the bridge years
During the period between now and JSW JFE's full expansion, transformer manufacturers need uninterrupted access to imported CRGO at manageable costs. Grade-differentiated anti-dumping duties, protecting conventional CGO where domestic supply exists, but exempting Hi-B and domain-refined where it does not, would balance protection with supply access. Time-bound exemptions or reduced duties for transformer makers under utility contracts could provide further relief.
2028 to 2030, and the monopoly question
The arrival of JSW JFE's full 350,000-tonne capacity changes the procurement picture significantly. Transformer manufacturers will have a domestic source for conventional CGO with rupee-denominated pricing and shorter lead times. The priority in this phase is ensuring that domestic supply is competitively priced. A single-producer domestic monopoly protected by anti-dumping duties could charge above import-parity, transferring the duty benefit from transformer makers to the steel producer.
A second domestic producer (Nippon Steel via AM/NS, or POSCO with a non-JSW partner) would create the competitive domestic market that transformer manufacturers need. Two producers competing on price, quality, and grade availability would benefit the downstream industry more than any trade policy calibration.
After 2030, the grade problem returns
The long-term need is domestic production of Hi-B and domain-refined CRGO. As BEE norms tighten further, the highest-efficiency transformers will require grades that conventional CGO cannot deliver. Nippon Steel (which invented Hi-B) entering India through AM/NS would address this directly. Without domestic Hi-B production, India remains structurally dependent on imports for its highest-performance transformers, regardless of how much conventional CGO capacity is built.
How much does the expansion really fix?
JSW JFE's expansion from 50,000 to 350,000 tonnes transforms India's CRGO supply position, but it does not eliminate the supply problems. A summary of what changes and what persists:
| Dimension | Before Expansion (~2026) | After Expansion (~2028) |
|---|---|---|
| Domestic capacity | ~50,000 t | 350,000 t |
| Import dependence | ~90% | ~50-55% |
| Number of domestic producers | 1 | 1 (still) |
| Hi-B domestic availability | None | None (still) |
| Domain-refined domestic | None | None (still) |
| FX exposure | 90% of procurement | ~50% of procurement |
| BIS friction on imports | Affects 90% | Affects ~50% |
| Single-producer risk | Yes | Yes, larger but still one company |
The expansion is necessary, import dependence falling from 90% to 50-55% is a meaningful improvement. But three structural problems persist: single-producer concentration risk, zero domestic Hi-B/domain-refined capability, and a still-significant import bill subject to FX and trade-policy uncertainty.
The transformer industry's ideal outcome is not the elimination of CRGO imports. It is the creation of a competitive domestic supply base with multiple producers offering the full grade range, alongside continued access to international supply for grades and volumes that domestic producers cannot yet match. Protection without competition creates a different vulnerability (domestic monopoly pricing) that is just as damaging to the industry as import dependence.
