Indian Abrasives - Sector Report | Premiumization Drives the Next Upcycle

India's Abrasives sector blends capex up-cycle with structural premiumization - demand from automotive precision, aerospace, electronics, semiconductor and EVadjacent applications carrying higher margins and stickier relationships. Growth is lumpy: 2-3 muted years precede ~2 strong ones, full-cycle CAGR tracking IIP/GDP growth, lifted by premiumization. Core abrasives (~$1.1bn TAM) and refractories ($1.85bn) grow mid-to-high single digits; super abrasives ($360mn, 9.5% CAGR) and technical ceramics ($1.05bn, 8.3% CAGR) are the high-growth differentiators. China's cost dominance leaves Indian players' edge in application engineering, qualification cycles and upstream integration — moats hard to arbitrage on price. We see a nascent upcycle, preferring a pecking order of GNO, CUMI, and then Wendt on fundamentals and risk-reward.

Grindwell Norton:

GNO stands out on risk-reward with remarkable operating margin stability and strongest business quality in our coverage, supported by Saint-Gobain’s 51.6% promoter holding, resilient consolidated EBITDA margins through the cycle and a judicious mix of higher-value performance polymers and premium ceramics serving automotive, pharma, biopharma, semiconductor and data-center endmarkets. Its 1.9% stake in Saint Gobain India Pvt. Ltd (SGIPL) strongly complement its business portfolio. GNO could also benefit from easing Chinese competition as export rebates are withdrawn and Chinese prices rise. Our FY26–29E estimates imply 10.3%/11.7%/12.1% revenue/EBITDA/PAT CAGR, lower than consensus estimates by 3-4 percentage points.

Carborundum Universal:

CUMI’s moat rests on upstream bauxite/alumina/SiC integration and Ceramics, its highest EBITDA margin segment (24.7%), now riding semiconductor and defense qualification ramps — a genuine structural shift, not cyclical. Consolidated EBITDA margin fell from 14.5% in FY25 to 11.1% in FY26 reflecting operating losses at its subsidiaries ─ AWUKO, Foskor and Rhodius. With AWUKO and Foskor soon winding up, we expect these drags to fade meaningfully going forward. Another subsidiary, Russia's VAW, though profitable, is OFACsanctioned since January 2025, capping valuation; a Russia-Ukraine resolution and sanctions relief would be meaningful upside, though timing is unpredictable and excluded from our base case. Rhodius's turnaround also hasn't happened yet — achieving it is a further lever, not yet priced in. Our FY26–29E estimates imply
11.0%/27.3%/28.6% revenue/EBITDA/APAT CAGR, in-line with consensus estimates.

Wendt India:

Wendt remains the purest listed exposure to India's super abrasives category and has the best segment-level economics of any single business in the coverage — Super Abrasives alone earns a 25.7% EBITDA margin on 64% of FY26 revenue. But the loss-making Machines & Accessories segment (-35.5% EBITDA margin) has pulled consolidated FY26 EBITDA margin down to 13.6% from 22.5%. While the structural story (super abrasives growth, machine-segment turnaround optionality) is intact, the risk-reward trade off remains unattractive; Our FY26–29E estimates imply revenue/EBITDA/PAT CAGR of 10.3%/27.9%/40.5%.

Valuation and view:

We value GNO, CUMI and Wendt using a blend of P/E and EV/EBITDA, with a SOTP approach for CUMI and Wendt where appropriate. GNO offers the strongest risk-reward at current levels, supported by superior business quality and earnings visibility. CUMI is a turnaround story in the making as drag from loss-making subsidiaries fades. Wendt also looks fundamentally attractive post the parent company’s exit but valuation leaves less headroom. We would use a 10–15% correction in Wendt as an opportunity to accumulate, while GNO and CUMI remains our preferred bet at current prices. Key risks: Reintroduction of export rebates in China, increase in competition, and prolonged economic slowdown.

FAQs on Indian Abrasives sector report

India’s abrasives industry is evolving beyond conventional applications, with premiumization, capital expenditure and demand from automotive, aerospace, electronics, semiconductor and EV-linked industries becoming important growth drivers. The following FAQs explain the key sector themes and company-level factors highlighted in the report.

What is driving growth in India's abrasives sector?

Growth is being supported by the capex cycle and increasing demand for precision and higher-performance abrasives. Automotive, aerospace, electronics, semiconductor and EV-adjacent applications are contributing to premiumization and potentially higher-value demand.

What is premiumization in the abrasives industry?

Premiumization refers to the increasing adoption of higher-value, technically differentiated abrasives and related materials. Super abrasives and technical ceramics are examples of segments where specialized applications can support higher margins and stronger customer relationships.

What are the key growth segments in India's abrasives market?

Core abrasives and refractories remain important segments, while super abrasives and technical ceramics represent relatively faster-growing opportunities. The report identifies these specialized categories as key differentiators within the broader abrasives and materials ecosystem.

Why is Grindwell Norton important in the Indian abrasives sector?

Grindwell Norton has exposure to abrasives, performance polymers and premium ceramics serving industries including automotive, pharmaceuticals, biopharmaceuticals, semiconductors and data centres. Its operating-margin stability and diversified applications are key factors discussed in the report.

What are the key factors affecting Carborundum Universal?

Carborundum Universal benefits from upstream integration across bauxite, alumina and silicon carbide, along with its ceramics business. Semiconductor and defence qualification opportunities are important structural drivers, while subsidiary performance has affected consolidated margins.

Why is Wendt India exposed to the super abrasives opportunity?

Wendt India provides focused listed exposure to super abrasives. Its Super Abrasives segment has strong segment-level economics, while the Machines & Accessories business has reduced consolidated profitability. A potential turnaround in this segment represents an additional variable.
