Diesel Exhaust Fluid Market Report 2026

The diesel exhaust fluid market size has grown strongly in recent years. It will grow from $39.79 billion in 2025 to $43.13 billion in 2026 at a compound annual growth rate (CAGR) of 8.4%. The growth in the historic period can be attributed to vehicle emission regulations, diesel engine dominance, commercial vehicle growth, environmental compliance mandates, scr technology adoption.

The diesel exhaust fluid market size is expected to see strong growth in the next few years. It will grow to $58.64 billion in 2030 at a compound annual growth rate (CAGR) of 8%. The growth in the forecast period can be attributed to stricter emission norms, expansion of heavy-duty vehicle fleets, infrastructure development, demand for low-NOx engines, regulatory enforcement intensity. Major trends in the forecast period include rising SCR system adoption, expansion of emission compliance solutions, bulk def supply growth, improved storage and handling systems, aftermarket demand expansion.

The diesel exhaust fluid market is poised for growth due to increasing interest in heavy-duty vehicles. These vehicles, designed for tough tasks such as long-distance transportation and industrial use, are gaining popularity for their reliability and efficiency. Manufacturers are integrating diesel exhaust fluid (DEF) systems into these vehicles to meet emissions regulations, reduce environmental impact, and improve fuel efficiency. This trend supports sustainability efforts while meeting modern transportation demands. For example, heavy truck production in April 2024 reached 9.71 million units, showing significant growth from earlier in the year, according to the Board of Governors of the Federal Reserve System.

Major players in the diesel exhaust fluid market are focusing on innovations such as specialized additives for DEF systems. These additives address specific challenges and enhance the performance of Selective Catalytic Reduction (SCR) systems in diesel vehicles. For instance, Liqui Moly GmbH launched an additive designed for AdBlue or DEF in February 2024. This additive, DEF Anti Crystal Additive Concentrate, protects the SCR system from damage due to crystallization and freezing of AdBlue, ensuring functionality even in sub-zero temperatures.

In October 2023, Cummins Inc. acquired two commercial vehicle manufacturing plants from Faurecia SE. This acquisition strengthens Cummins' position in low-emission products and enhances its capabilities in the commercial vehicle exhaust after-treatment market. Faurecia SE, known for its expertise in vehicle exhaust fluid systems, contributes to Cummins' commitment to meeting industry demands and ensuring continuity for employees and customers.
