Software developers are eligible for national AI funds, which will accelerate the rollout of defect-recognition algorithms. While component supply gaps for X-ray tubes persist, substitution schemes reduce import exposure by 1.2 percentage points of the CAGR and lay the groundwork for a stronger domestic value chain.

Certified Technician Shortage Constrains Service Capacity Expansion

China needs 15,000 additional Level-III specialists by 2030, but training pipelines add fewer than 3,000 annually, widening a skills gap that trims growth by 1.8 percentage points. ISO 9712 certification requires multi-year apprenticeships, which can delay workforce replenishment. Pay premiums siphon talent to tier-1 cities, leaving inland hubs understaffed. Smaller factories face longer wait times and higher service fees, deterring adoption of proactive inspection regimes.

High Equipment Costs Limit SME Adoption of Advanced Technologies

Industrial CT systems priced between USD 800,000 and USD 1.5 million exceed the budgets of fabricators with annual revenues under USD 10 million, hindering the diffusion of technology. Phased-array UT packages exceeding USD 200,000 also require specialized probes and software, lifting lifecycle costs. Financing hurdles persist as banks struggle to value NDT assets, and the thin secondary market curbs leasing options. Consequently, SMEs rely on third-party service providers, sustaining the dominance of the outsourced model but limiting the upside of equipment sales.
