Sharp fluctuations in pig iron, ferrous scrap, and coke prices are increasing input-cost uncertainty and pressuring foundry profit margins
One of the major restraints affecting the iron casting market is the volatility of raw material prices, particularly pig iron, ferrous scrap, and coke, which directly affect the cost of production as well as the profit margin of the foundry industry. Iron casting companies rely on the constant availability of metal and energy inputs used for the melting process in order to sustain their production costs. In case the cost of inputs rises faster than that of output prices, foundries are forced to incur extra expenses or renegotiate contracts with car makers, machinery and infrastructure companies.
The raw material price fluctuations became one of the factors that restricted the iron casting industry. In April 2026, according to the Indian Foundry Association's Foundry Frontier, prices of pig iron had risen up to nearly 20% in the past two to three months even though the price of iron ore and coke was more or less steady across the globe and India. It was also mentioned in the report that 95% of foundries come under the category of MSMEs and that the order cycle is 5-6 months long. In case there is an increase in the cost of raw materials, and it takes such a long time to accept orders from customers, this might affect the profit margins of the companies in the industry.
