Over the past decade, the rapid growth of the global logistics industry and the trend towards stricter emissions regulations have driven up the demand for its use. DEF solution (Diesel Exhaust Fluid) Explosive growth. DEF – with its main components being 32.5% pure urea and 67.5% deionized water – plays a central role in the system. SCR (Selective Catalytic Reduction)This helps trucks and container vehicles meet Euro 5, Euro 6 emission standards and similar regulations in other countries.

The period 2025–2030 is projected to be the “golden age” of DEF as logistics continues to expand and environmental policies become increasingly stringent. So how will DEF demand change? What factors will drive growth? And what opportunities exist for manufacturing and distribution businesses in Vietnam?
Global Trends: Green Logistics and the Driving Force for DEF
Growth in the logistics industry
-
According to market reports, global road transport volume is expected to grow at an average rate 5–6% per year during the period 2025–2030.
-
In the Asia-Pacific region in particular, the growth rate is even higher due to the boom in cross-border trade and e-commerce.

Strict emissions requirements
-
Europe continues to maintain Euro 6 and is studying Euro 7 (which could be implemented from 2027).
-
North America is implementing regulations equivalent to EPA 2027, further tightening the permitted levels of NOx.
-
Vietnam, along with many other Southeast Asian countries, will also adopt the standard. Euro 5 comprehensive from 2025, progressing towards Euro 6 in the following years.
These two driving forces are what transformed DEF has become an indispensable product , for trucks, container vehicles, and passenger buses using diesel engines.
Global DEF demand forecast 2025–2030
Market research organizations are presenting positive growth figures:
-
The global DEF market size has reached approximately $50 billion by 2030, nearly double the figure for 2024.
-
The projected average annual growth rate (CAGR) ranges from 8–10%/year.
-
The Asia-Pacific region will occupy trên 40% nhu cầu toàn cầu nhờ lượng xe tải hạng nặng tăng mạnh và nhu cầu logistics xuyên biên giới.
Vietnam Market: Demand for DEF is booming.
Main motivation
-
Euro 5 standards to be implemented from 2025: Newly manufactured and imported trucks and buses must meet the regulations.
-
The logistics industry is growing rapidly.: Vietnam is among the top 10 fastest-growing logistics markets in the world, with an average growth rate of 14–16% per year.
-
Expanding heavy truck fleet: The demand for container and cargo transportation through seaports is constantly increasing.

Forecast scale
-
In 2025, the demand for DEF in Vietnam is estimated to reach approximately 300–350 million liters.
-
By 2030, this number could exceed 700 million liters, equivalent to the average growth rate 15–18%/ year – higher than the global average.
Challenges and risks
Despite its promising market potential, DEF in Vietnam still faces many challenges:
-
Counterfeit goods, substandard goods: This affects vehicle performance and the confidence of transportation businesses.
-
Costs of producing and importing industrial urea: Global urea price fluctuations can impact DEF prices.
-
Lack of standardized and consistent monitoring: Market quality control remains limited, creating loopholes for counterfeit products to circulate.
Opportunities for domestic manufacturing businesses
The development of the market opens up great opportunities for domestic brands:
-
DEF production meets ISO 22241 standards being produced right here in Vietnam helps reduce import costs and stabilize the supply.
-
Building a professional distribution chain to control quality and build trust among transportation businesses.
-
Investing in research and automation to optimize costs and enhance competitiveness.
For example, businesses such as BlueOne we are pioneering the production of internationally standardized DEF in Vietnam, contributing to shaping the market and gradually replacing imported sources.
Forecast of DEF demand in the logistics industry 2025–2030
By considering all growth factors, we can make the following forecast:
-
2025–2027: During the period of explosive growth directly impacted by Euro 5, transport businesses were required to use DEF that met the standards.
-
2028–2030: Demand continues to grow steadily thanks to fleet expansion combined with stricter emissions controls. Vietnam could become one of the largest DEF (Device Fuel Oil) markets in Southeast Asia.
During the period 2025–2030, DEF solution will become a vital element for the logistics industry. Demand is growing strongly not only in major transportation hubs like the US, Europe, and China, but also in Vietnam. Manufacturing and distribution businesses that seize this opportunity, ensure quality, transparency, and a stable supply will gain a sustainable competitive advantage.
A green and sustainable logistics industry is indispensable. DEF meets international standards – a small product with a huge impact on operational efficiency and environmental protection.
