Strategic Analysis of the Global Medium- and Heavy-Duty Commercial Vehicle Aftermarket, 2025

The global commercial vehicle market faced significant headwinds in 2024, with declining sales in the medium-duty (MD) and heavy-duty (HD) truck segments. This trend continued into the first half of 2025. Economic uncertainty, exacerbated by trade and tariff policies in the United States, stricter emission standards, rising inflation, supply chain disruptions, and reduced consumption, among other challenges, adversely affected the global truck replacement parts aftermarket.

The overall vehicles-in-operation (VIO) of the MD and HD trucks segments stood at 49.8 million units globally in 2024, with many fleets retaining older vehicles. The majority of truck parts revenue came from engine and transmission systems; heating, ventilation, and air conditioning (HVAC) and thermal management systems; fuel management components; sensors; exhaust systems; tires; and lubricants.

The overall aftermarket is projected to grow by 4.3% in 2025, supported by countries pursuing alternative paths to ensure domestic economic stability. Despite global challenges, markets such as China, India, and select Latin American countries are showing steady growth, indicating a positive outlook for the freight and trucking sectors.
