Third-Party Inspection Services in China
Independent inspection and witnessing for global TIC organizations, EPC quality teams and overseas buyers — FAT and SAT witnessing, long-term resident inspectors, NDT, API-standard pipe inspection and factory audits, with English reports formatted to your template.
Eight Service Lines, One Standard of Independence
We operate as a compliant subcontractor to global TIC bodies: your ITP, your acceptance criteria, your report template — our inspectors and our on-the-ground speed. Every line below can be engaged as a one-off task or as part of a rolling program.
FAT Inspection

SAT Inspection
Site Acceptance Test witnessing during installation and commissioning across Chinese project sites — from power plants to industrial facilities — with structured punch-list and NCR management.
- Installation verification against vendor documentation
- Commissioning and functional run-test witnessing

Long-Term Site Secondment
A dedicated resident inspector stationed in your supplier's factory on a monthly retainer — your eyes on production, quality and shipping readiness every working day.
