In the early hours of February 28, 2026, Israel and the United States launched military strikes on Iranian targets, including leadership, air defense capabilities, missile sites, and the Islamic Revolutionary Guard Corps (IRGC) Navy. Iran responded with retaliatory missile and UAV attacks.

The conflict has created the most severe disruption to global energy markets since the 1970s, with the effective closure of critical shipping routes raising global recession and inflation risks. The disruptions from the U.S. and Israeli attacks on Iran spread quickly to commercial aircraft, shipping lanes, and the world‘s energy supply.

9.2 Impact on Energy Prices and Production Costs

Natural Gas and Electricity Costs

Calcination—the process of heating diatomite to 800–1,200°C—is highly energy-intensive. Natural gas is the primary fuel for calcination kilns, and electricity powers crushing, milling, and classification equipment.

The conflict has driven energy price volatility. Fuel shortages and freight surcharges: from March 2–16, 2026, the average nationwide price of U.S. gasoline spiked, reflecting broader energy market disruptions. Higher natural gas and electricity costs directly increase the production cost of calcined and flux-calcined diatomaceous earth, which together account for approximately 67–70% of the market.

Impact on Chinese Producers

China is a major producer of diatomaceous earth and a significant exporter to Asia-Pacific markets. However, China is also the world‘s largest importer of oil and natural gas, with approximately 46% of oil imports from the Middle East. Disruption to Hormuz shipping directly threatens China‘s energy security and manufacturing costs. Chinese DE producers face higher energy bills, which may be passed on to customers in the form of price increases.

Impact on European Producers

Europe relies heavily on imported natural gas, with LNG shipments passing through the Suez Canal and Red Sea routes. The conflict has disrupted these shipping lanes, contributing to natural gas price volatility. European DE producers—including Imerys (France), which operates significant calcination facilities—face elevated energy costs.

9.3 Impact on Shipping and Logistics Costs

The conflict has threatened the Strait of Hormuz, a narrow waterway between the Persian Gulf and the Arabian Sea through which approximately 20% of global oil exports and a significant portion of container traffic pass. Even without a complete closure, the threat of disruption imposes a “war premium” on shipping and insurance.

Direct Impacts on DE Logistics:

• Ocean freight costs: Shipping rates from Asia to Europe and North America have increased due to rerouting and higher insurance premiums

• Transit delays: Rerouting vessels around Africa adds 10–14 days to transit times

• Container availability: Disruptions affect the availability of shipping containers for bulk mineral exports

• Inland transportation: Higher diesel prices increase truck and rail freight costs

For a low-value-to-weight product like diatomaceous earth, increased shipping costs represent a significant percentage of final product price, potentially making exports from distant producers uncompetitive in certain markets.

9.4 Impact on Key Regional Markets

Middle East and Africa

The Middle East is a growing market for diatomaceous earth, driven by desalination, water treatment, and construction. However, the conflict:

• Deters foreign investment: International partners may delay or cancel infrastructure projects requiring DE

• Disrupts construction timelines: Project sites may be affected by military activity or civil unrest

• Increases insurance and security costs: Operating in the region requires additional measures

Asia-Pacific

Asia-Pacific is the fastest-growing DE market. However, the region is highly exposed to the conflict‘s effects through:

• Energy imports: China, India, Japan, and South Korea are major importers of Middle Eastern oil and gas

• Export shipping: DE exports from China to Europe and North America face higher costs and delays

• Raw material costs: Higher energy prices increase production costs for Chinese DE manufacturers

North America

North America is the largest DE market, with significant domestic production. The region is relatively insulated from direct shipping disruptions, as most DE consumed in North America is produced domestically (U.S., Mexico). However, U.S. producers face higher energy costs (natural gas prices are influenced by global LNG markets) and potential competition from imports facing disrupted supply chains.

9.5 Broader Economic Implications

The conflict has heightened global recession and inflation risks. The effective closure of critical shipping routes and energy market disruptions are raising costs across every sector of the economy. The disruptions are spreading quickly to commercial aircraft, shipping lanes, and the world‘s energy supply.

For the diatomaceous earth market, this means:

• Weaker demand in recession-sensitive sectors: Construction, manufacturing, and automotive sectors may reduce consumption if economic growth slows

• Higher input costs: Energy, transportation, and packaging costs are all elevated

• Supply chain uncertainty: Just-in-time inventory strategies are being reconsidered, leading to increased safety stock and higher working capital requirements

• Currency volatility: A stronger U.S. dollar makes dollar-denominated DE more expensive for buyers in other currencies

9.6 Summary of Geopolitical Impact

The USA-Israel-Iran conflict has inflicted a significant shock on the global diatomaceous earth market through three primary channels:

1. Energy price volatility: Higher natural gas and electricity costs directly increase calcination costs

2. Shipping disruptions: Higher freight costs and transit delays affect international trade

3. Economic uncertainty: Recession risks may dampen demand from construction and industrial sectors

While the conflict may eventually de-escalate, the fundamental concentration of energy resources and shipping routes in geopolitically volatile regions means that supply chain vulnerability will remain elevated. DE industry participants should:

• Diversify energy sources: Invest in energy efficiency, waste heat recovery, and renewable energy to reduce exposure to fossil fuel volatility

• Build inventory buffers: Maintain higher safety stock of finished goods to buffer against shipping disruptions

• Consider regional production: Establish processing facilities in multiple regions to serve local markets and reduce shipping dependency

• Monitor geopolitical developments: Use scenario planning to prepare for potential escalations or de-escalations

• Strengthen customer relationships: Long-term contracts with price adjustment mechanisms provide stability during uncertain times

10. Quick Recommendations for Stakeholders

For Manufacturers

• Invest in energy efficiency: Calcination is energy-intensive; invest in waste heat recovery, more efficient kilns, and alternative fuels (biomass, hydrogen-ready systems) to reduce exposure to fossil fuel price volatility.

• Expand food-grade certification portfolio: Food-grade DE accounts for approximately 70% of consumption and commands premium pricing. Invest in ISO 22000, FSSC 22000, Kosher, and Halal certifications to access premium markets.

• Develop emerging application expertise: Position the company as a solution provider in high-growth segments: pet care (natural flea control, cat litter), personal care (exfoliants), and organic agriculture (pest control, soil amendment).

• Regionalize supply chains: Reduce dependency on long-distance shipping by establishing processing facilities or distribution hubs in key regional markets (Asia-Pacific, Europe, Latin America).

• Pursue vertical integration: Secure access to high-quality diatomite reserves through acquisition or long-term mining agreements. Resource depletion is a growing concern in established mining regions.

• Invest in quality and consistency: Consistent particle size distribution, permeability, and purity are critical for filtration applications. Automated process control and rigorous quality testing are competitive differentiators.

• Build strategic inventory buffers: Maintain safety stock of finished goods to buffer against shipping disruptions and energy price spikes.

For End-Users (Beverage Manufacturers, Water Utilities, Industrial Processors)

• Audit supply chain resilience: Assess your DE suppliers‘ geographic diversity, energy exposure, and shipping route dependencies. Diversify suppliers to mitigate single-source risk.

• Consider alternative filtration technologies for sensitive applications: While DE remains the most cost-effective solution for most applications, evaluate membrane filtration or other alternatives for high-value products where precision justifies higher cost.

• Lock in long-term supply agreements: The geopolitical environment is uncertain. Secure DE supply through multi-year contracts with price adjustment mechanisms tied to verifiable indices.

• Implement used DE recycling or beneficial reuse: Spent DE can be used as soil amendment, cement additive, or landfill cover. Investigate local options to reduce disposal costs and environmental footprint.

• Maintain safety stock: Given supply chain vulnerabilities, maintain 30–60 days of safety stock for critical DE grades.

For Investors

• Target companies with diverse geographic operations: Producers with mining and processing facilities in multiple regions (North America, Europe, Asia-Pacific) are better positioned to weather regional disruptions.

• Assess energy exposure: Companies with energy-efficient calcination technologies, waste heat recovery, or captive energy sources have lower exposure to natural gas price volatility.

• Evaluate reserve quality and longevity: High-quality, long-reserve-life deposits are strategic assets. Assess producer reserve portfolios and depletion timelines.

• Monitor emerging application growth: Companies positioned in high-growth segments (pet care, personal care, organic agriculture) will outperform those dependent on mature filtration markets.

• Watch geopolitical developments: The USA-Israel-Iran conflict directly affects energy prices and shipping costs. Assess portfolio companies‘ exposure to these risks.

• Consider vertical integration plays: Companies that control mining, processing, and distribution are better positioned than pure-play processors.

For Policymakers

• Support domestic mining and processing: Strategic minerals—including industrial minerals like diatomite—deserve policy support for domestic production to reduce import dependency.

• Invest in energy infrastructure: Reliable, affordable natural gas and electricity are essential for DE processing. Support energy infrastructure development and renewable energy incentives.

• Harmonize food-grade certification standards: Reduce compliance burden for DE producers by harmonizing food-grade standards across major markets (U.S., EU, Japan, China).

• Facilitate used DE recycling: Develop regulatory frameworks and incentives for the beneficial reuse of spent filter aid, reducing landfill burden and supporting circular economy.

• Address silica exposure regulations carefully: Balance worker protection with the economic importance of the diatomite industry. Evidence-based, risk-proportionate regulations support both safety and industry viability.
