The global Non-Destructive Testing (NDT) market is projected to grow from USD 16.3 billion in 2025 to USD 32.5 billion by 2035, registering a compound annual growth rate (CAGR) of 7.1%, according to recent industry estimates. The expansion is being driven by rising industrial safety standards, accelerated automation across production lines, and the growing importance of preventive maintenance across critical industries.
The increasing complexity of industrial systems—ranging from aerospace and defence to automotive manufacturing and energy—is driving demand for high-precision inspection solutions that ensure component reliability and structural integrity without causing damage. Advanced NDT technologies such as phased array ultrasonic testing (PAUT), digital radiography, and computed tomography (CT) are gaining prominence due to their enhanced flaw detection accuracy and compatibility with modern automation systems.
The integration of AI, machine learning, and cloud-based analytics has emerged as one of the most influential trends reshaping the sector. These technologies enable real-time defect detection, predictive maintenance, and remote asset monitoring, helping industries transition from reactive to proactive inspection regimes. In April 2025, SGS S.A. launched an AI-powered cloud analytics solution that facilitates remote inspection data exchange and predictive asset maintenance, underscoring how digital transformation is redefining quality assurance in NDT.
Market Drivers and Challenges
Growth in aircraft production and stringent safety certifications are fuelling demand for next-generation NDT techniques. Leading companies like GE Inspection Technologies are integrating high-resolution ultrasonic and radiographic systems into airline maintenance programs to ensure compliance with evolving aviation safety standards.
However, the high cost of advanced NDT systems remains a significant restraint, particularly for small and medium-sized inspection firms. The implementation of 3D X-ray and digital imaging technologies continues to challenge smaller players due to the high costs of equipment, calibration, and operational maintenance.
Infrastructure and Regional Momentum
Infrastructure investment has become a new growth avenue for NDT applications. In March 2025, TÜV Rheinland AG launched an infrastructure inspection service to assess bridges, tunnels, and rail systems for structural safety and stability—highlighting the growing intersection between NDT and large-scale public projects.
North America continues to dominate the global market due to advanced technological infrastructure, strict regulatory frameworks, and strong industrial presence. The U.S. Infrastructure Investment and Jobs Act (2024) has amplified inspection demand across civil and energy sectors, while the adoption of AI-enabled and automated NDT systems strengthens the region’s leadership.
Meanwhile, the Asia-Pacific region is witnessing the fastest growth rate globally, driven by rapid industrialization and manufacturing expansion in China, India, Japan, and South Korea. Major investments in aerospace, renewable energy, and transportation infrastructure are fueling NDT deployment. In response, Eddyfi Technologies expanded its operations in Singapore in 2025 to meet Southeast Asia’s rising demand for automated testing solutions.
Strategic Developments and Industry Moves
The NDT industry continues to consolidate through high-value collaborations and acquisitions.
- In August 2025, MISTRAS Group, Inc. secured a major contract with Bechtel to deliver essential NDT services for the U.S. Department of Energy’s Hanford Vit Plant nuclear waste project.
- In July 2025, NDT Global GmbH & Co. KG acquired Entegra, integrating ultrasonic testing and data-management platforms to enhance end-to-end pipeline integrity services worldwide.
The Path Ahead
As NDT technologies continue to evolve, the market is transitioning from conventional inspection toward intelligent, connected systems that integrate sensors, AI algorithms, and cloud-based decision platforms. The shift underscores the growing role of NDT not only as a quality assurance mechanism but as a strategic intelligence tool—enhancing asset reliability, operational efficiency, and industrial safety on a global scale.
