The NDT and inspection market size was USD 14.2 billion for 2025, and it will grow by 9.6% during 2026–2032, to reach USD 26.9 billion by 2032.
The market is driven by tightening asset-integrity mandates across the oil & gas, aerospace & defense, and manufacturing industries, along with an industry-wide shift from schedule-based inspections toward condition-based maintenance and AI-enabled defect detection. Ultrasonic testing, radiographic testing, eddy current testing, magnetic particle testing, visual testing, and liquid penetrant testing remain the core non-destructive inspection techniques supporting the integrity, reliability, and safety of ageing industrial infrastructure worldwide.
Persistently high capital investment in energy infrastructure continues to reinforce demand for non-destructive testing and inspection services. According to the International Energy Agency (IEA), global energy investment is projected to reach approximately USD 3.3 trillion in 2025. This investment is supporting continued development and maintenance of pipelines, refineries, power facilities, and offshore assets that rely extensively on ultrasonic and radiographic testing for asset integrity management. Parallel growth in precision manufacturing is expanding demand for advanced inspection technologies. According to the National Bureau of Statistics of China, China's equipment manufacturing value-added increased by 9.2% year over year in 2025. This growth is accelerating the adoption of eddy current testing and phased-array ultrasonic testing (PAUT) across electronics, automotive, and aerospace component inspection and quality assurance.
Inspection delivery is shifting from manual, schedule-based fieldwork toward automated, data-centric workflows. NDT service providers are integrating artificial intelligence (AI)-based defect classification, drone-enabled visual inspection, and robotic inspection platforms into ultrasonic, radiographic, and visual testing programs. This integration is enabling larger asset coverage with fewer on-site labor hours, and it is generating comprehensive digital inspection records. This transformation is particularly evident in confined and hazardous environments, including offshore platforms, nuclear facilities, storage tanks, and pipelines, where robotic systems reduce personnel exposure while improving the consistency and repeatability of ultrasonic and eddy current inspections.
As cloud-based asset integrity managementv platforms become more widely adopted, inspection data is increasingly integrated with predictive maintenance and digital asset management systems. This integration is enabling operators to move from periodic inspections to condition-based maintenance strategies. In July 2025, Waygate Technologies introduced the Krautkramer WheelStar RPS, a fully automated robotic ultrasonic testing system utilizing phased-array matrix technology for railway wheel inspection. The system automates the inspection process, generates standardized digital inspection reports, and reduces inspection cycle time to approximately six minutes per wheelset. This performance demonstrates the industry's shift toward intelligent, AI-enabled, and robotic NDT solutions. This evolution is strengthening long-term service relationships between asset owners and inspection providers through continuous monitoring, analytics, and lifecycle asset management. This trend is expected to continue as industries accelerate digital transformation and expand the use of electronic inspection documentation.
Decades-old refineries, pipelines, and pressure vessels across mature industrial economies require recurring structural verification to remain within design safety margins. This structural verification requirement is driving demand for ultrasonic, radiographic, and magnetic particle testing. Codes such as the ASME Boiler and Pressure Vessel Code (BPVC) mandate periodic nondestructive examination for covered equipment, and compliance with these design and inspection requirements has become a baseline cost of operation rather than a discretionary expense. According to the ASME Boiler and Pressure Vessel (BPV) Certification Program, more than 7,000 organizations across 95 countries hold BPV certification.
This widespread adoption reflects standardized pressure equipment manufacturing, inspection, and quality assurance requirements that sustain baseline demand for non-destructive testing services. As aging fleets of pressure equipment continue operating beyond their original design life in North America and Europe, operators are shifting from calendar-based inspection intervals toward risk-based inspection programs that combine more frequent NDT assessments with predictive analytics. This trend is expected to reinforce steady demand for NDT inspection services through 2032.
A persistent shortage of technicians holding ASNT- or ISO 9712-certified qualifications is constraining the growth of the NDT and Inspection market by limiting service capacity and slowing the execution of inspection projects. Level II and Level III certification requires extensive training, qualification examinations, and documented supervised work experience that cannot be rapidly expanded to meet short-term demand. The American Society for Nondestructive Testing (ASNT) certification framework requires candidates seeking Level II and Level III certification to demonstrate both practical experience and technical competency before independent inspection responsibilities can be undertaken.
The lengthy certification pathway, combined with increasing demand from the oil & gas, aerospace & defense, power generation, manufacturing, and renewable energy sectors, continues to limit the availability of qualified inspection personnel. NDT service providers are increasingly investing in automation, artificial intelligence, remote visual inspection, and robotic inspection platforms to improve productivity and reduce dependence on on-site certified technicians. Nevertheless, the shortage of experienced personnel is expected to remain a key constraint on inspection capacity expansion as demand for asset integrity management and regulatory compliance continues to grow.
The rapid global buildout of renewable energy capacity is creating a fast-growing inspection niche beyond traditional oil & gas and manufacturing end uses. Wind turbine blades, towers, and solar photovoltaic (PV) installations require specialized ultrasonic, thermographic, and visual inspection techniques to detect delamination, corrosion, fatigue damage, and micro-cracking that conventional maintenance practices may not readily identify. According to the International Renewable Energy Agency (IRENA), global wind power capacity grew by 14% in 2025, with record additions of 158.7 GW, while total renewable power capacity additions reached 692 GW. The expanding installed base of utility-scale wind assets is increasing demand for recurring blade, tower, and structural integrity inspections throughout their multi-decade operating lifecycles.
In response, NDT providers are developing drone-based thermographic imaging, robotic inspection platforms, and advanced ultrasonic testing solutions purpose-built for wind turbine blade inspection. This is positioning specialized inspection service providers and equipment manufacturers to benefit from continued renewable energy deployment through 2032.
The services category holds the larger market share of 75%, in 2025, driven by the need for certified inspection expertise and compliance with stringent industry regulations. The extensive training, qualification examinations, and documented supervised work experience required for ASNT and ISO 9712 certification make it more cost-effective for industries such as oil & gas, aerospace & defense, manufacturing, and power generation to engage certified third-party inspection providers. The American Society for Nondestructive Testing (ASNT) administers personnel qualification and certification programs that require candidates to demonstrate technical competency before achieving Level II or Level III certification, reinforcing the continued reliance on specialized NDT service providers.
