North America Market Trends
Grey Cast Iron Price Index Movement in the USA
In Q2 2025, the Grey Cast Iron Price Index in the USA rose by 9.9% quarter-over-quarter. This sharp increase highlighted the strong recovery in domestic industrial activity, with the automotive sector playing a leading role.
The U.S. automotive industry remains one of the largest consumers of grey cast iron, using it extensively in engine blocks, cylinder heads, brake components, and structural applications. The robust rebound in vehicle sales, particularly in the light truck and electric vehicle (EV) segments, spurred demand for castings. Even as technological shifts move toward lighter-weight materials, cast iron maintains its relevance due to its superior durability and cost efficiency.
Role of Automotive Demand
The automotive industry’s purchasing momentum was a key driver. Demand spikes from OEMs and tier-1 suppliers placed upward pressure on prices. In addition, the U.S. government’s infrastructure programs boosted requirements for construction machinery, which further contributed to higher consumption of grey cast iron components.
The fleet renewal cycle also played a part. Post-pandemic supply chain challenges had delayed deliveries in previous years, creating pent-up demand that materialized strongly in Q2 2025. Foundries and suppliers ramped up operations to meet orders, pushing pricing upward.
Buyer Anticipation of Tariffs
Another important factor was forward buying behavior driven by tariff concerns. Market participants anticipated potential new trade restrictions on imported castings and semi-finished materials, particularly from Asian suppliers. Importers and domestic buyers sought to secure inventory early, creating a surge in purchases that tightened availability in the domestic market.
This proactive buying cycle artificially amplified demand, further lifting the index. Even companies that typically relied on “just-in-time” supply chains shifted strategies toward stockpiling, intensifying price competition.
Energy and Raw Material Costs
Energy costs remained moderately high across the U.S. in Q2 2025, particularly electricity and natural gas, both critical for foundry operations. Pig iron and scrap iron prices also edged higher, feeding into production costs. The combination of strong demand and input cost pressures made price increases almost inevitable, reinforcing the quarter’s bullish trend.
Outlook for North America
Looking ahead, North America’s grey cast iron market is expected to remain resilient, though the pace of growth may slow in Q3 as inventory corrections occur. Tariff outcomes will be crucial in shaping price momentum. If new duties are implemented, domestic prices could remain elevated. Conversely, if tariff concerns ease, speculative stockpiling may taper off, balancing the market.
Asia-Pacific Market Trends
Grey Cast Iron Price Index Movement in China
In sharp contrast to the U.S., the Grey Cast Iron Price Index in China fell by 2.3% quarter-over-quarter in Q2 2025. This decline was largely attributed to oversupply conditions and a subdued domestic demand environment.
China is one of the largest global producers of grey cast iron, supported by its expansive foundry capacity and integrated steel sector. However, the market in Q2 2025 demonstrated the challenges of excess production and limited domestic absorption.
Oversupply Conditions
Chinese foundries continued to produce at high capacity, encouraged by government-backed industrial programs and competitive exports. However, this capacity outstripped domestic demand levels. The result was a supply overhang that weighed on prices.
Despite efforts to balance production, smaller foundries resisted shutdowns due to financial pressures, exacerbating oversupply. Inventory buildup became a recurring issue, particularly in regions serving the machinery and construction equipment sectors.
Domestic Demand Weakness
Domestic consumption remained cautious, reflecting slower growth in China’s construction and infrastructure activities. Real estate sector challenges persisted, limiting demand for grey cast iron pipes, fittings, and heavy machinery components.
Automotive production also slowed compared to earlier quarters, partly due to weaker consumer confidence and competitive pressures from international brands. EV production growth, while positive, did not fully offset reduced demand in conventional vehicle casting requirements.

Export Market Competition
Exports provided some relief but faced stiff competition from other Asian suppliers and trade barriers in Western markets. Price-sensitive buyers in Southeast Asia absorbed some volumes, but margins remained thin. Global price competition, particularly with aggressive offers from smaller producers, restrained Chinese exporters from achieving meaningful gains.
Outlook for APAC
In Q3 2025, the Chinese grey cast iron market is expected to remain under pressure unless production cuts are implemented. Government stimulus aimed at boosting infrastructure could improve demand, but without strong measures to reduce oversupply, price recovery may be slow.
European Market Trends
Grey Cast Iron Price Index Movement in Germany
Germany, one of Europe’s most significant engineering and automotive hubs, saw the Grey Cast Iron Price Index rise by 8.7% quarter-over-quarter in Q2 2025. This increase highlighted a supply-driven price rally compounded by energy input costs and robust industrial sentiment.
Limited Local Supply
Germany’s foundry sector faced restricted production availability due to maintenance schedules and operational slowdowns in Q1, which carried over into Q2. As demand picked up, local supply constraints created upward momentum in pricing. Imports could not fully compensate due to high transport costs and delivery delays, further tightening the market.
Higher Energy Input Costs
Energy costs were a decisive factor in Europe’s price trajectory. Natural gas and electricity prices, while more stable compared to the 2022–2023 crisis period, remained significantly higher than historical averages. These elevated costs directly translated into increased casting prices.
Additionally, carbon emission compliance requirements added to cost burdens for foundries, especially in Germany, where environmental regulations are stringent.
Strong Demand from Mechanical and Plant Engineering
The mechanical and plant engineering sector acted as a backbone for grey cast iron demand in Germany. Equipment manufacturers, including those in heavy machinery, pumps, compressors, and renewable energy infrastructure, demonstrated healthy order books throughout Q2 2025.
The country’s robust export-oriented industrial base amplified consumption needs, supporting higher price levels despite elevated costs. Automotive applications also contributed, though not as strongly as in the U.S., given Europe’s gradual shift toward lighter alloys and EV-oriented materials.
Outlook for Europe
For Q3 2025, Germany’s grey cast iron prices are expected to remain firm as long as energy prices stay elevated and demand from engineering sectors continues. Seasonal slowdowns during summer may provide some relief, but the overall trend points to sustained higher pricing relative to 2024 levels.
