First phase to expand Synthetic Iron Oxide Pigment capacity by 50%, introducing new value-added products and strengthening operating efficiencies at Sahupuram
MUMBAI, India, Aug. 14, 2026 /PRNewswire/ -- DCW Limited announced a strategic investment programme of approximately ₹250 crore, marking the first phase of its next growth cycle.
The programme will focus on expanding Synthetic Iron Oxide Pigment (SIOP) capacity, introducing new value-added pigment products and strengthening captive power infrastructure at its Sahupuram manufacturing complex.
DCW plans to increase SIOP capacity by 50%, from approximately 30,000 tonnes per annum to 45,000 tonnes per annum, through a phased expansion. The investment follows record SIOP sales volumes in FY26, with the business operating at effectively full capacity, and is expected to support further growth across domestic and international markets.
Expanding into a Large & Growing Addressable Market
The expansion is supported by a sizeable global market and diversified end-use demand. Recent industry estimates place the global iron oxide pigments market at approximately US$2.5–2.7 billion in 2025 projected to reach approximately US$3.9 billion by 2033, representing a 4.6% CAGR. Asia-Pacific is the largest regional market, accounting for approximately 41.5% of global revenue as of 2025.
Iron oxide pigments are widely used across construction materials, paints and coatings, plastics and other industrial applications, providing a broad underlying demand base. These are also established end-markets for DCW's SIOP portfolio, which serves applications including construction, paints, paper, laminates, packaging, furniture, plastics and rubber.
The programme builds on DCW's multi-year shift towards higher-value chemicals. Over FY21–FY25, the Specialty Chemicals segment registered a 26% CAGR, while FY25 Specialty Chemicals EBITDA was 1.9x FY21 levels. Over the last five years, Specialty Chemicals have become the major contributor to the Company's profitability, providing a more resilient earnings base against swings in Basic Chemicals. DCW enters this investment cycle with a stronger balance sheet which turns Net Cash Positive at the exit of FY27, before any additional leverage for the proposed capex.
Alongside increasing capacity, DCW plans to introduce newer, value-added pigment grades, broadening its product portfolio and improving its ability to address higher-value applications and additional customer requirements. Management had previously indicated that product development in SIOP would increasingly focus on value-added grades alongside volume growth.
The Company will also invest in captive power infrastructure at Sahupuram to improve energy efficiency and strengthen the cost competitiveness of both its Basic and Specialty Chemicals businesses. This builds on DCW's existing renewable energy investments, the benefits of which have already begun to reflect in power costs.
Management Commentary
Mr. Saatvik Jain, President, DCW Limited, said:
"Over the last few years, we have strengthened our balance sheet, scaled Specialty Chemicals and improved operating efficiency. Specialty Chemicals are now a major contributor to profitability, providing a stronger base for our next phase of growth.
The ₹250 crore investment programme is focused on areas where we see clear opportunities to scale. With SIOP operating at high utilisation, an established customer base and growing end-market demand, the expansion will increase capacity while moving us further into value-added pigment products.
Alongside this, investments in energy efficiency will strengthen manufacturing competitiveness. Our balance sheet provides the flexibility to fund growth while maintaining financial discipline, with a continued focus on sustainable returns and long-term value creation."
