Independent third-party inspection · Since 2015
Quality is not inspected on delivery. It is verified at the source.
PSPP is an independent third-party inspection and QA/QC agency. We put a qualified inspector inside your supplier's factory — witnessing FAT, checking welds, dimensions and coatings, reviewing the manufacturing dossier — so nonconformities are raised before the equipment ships, not after it lands on your site.

The cost of assuming
A supplier's own QC report is not verification
Every weld rejected on site was already wrong in the factory. The only thing that changed is who pays to cut it out, and how much of your schedule it costs.
Unwitnessed manufacturing
You find out on site
The equipment arrives, the dossier looks complete, and the problem surfaces during installation or commissioning.
- Nonconformities appear after shipping, when correction costs a multiple of factory rework
- The supplier's own QC department signs off on the supplier's own work
- Hold points and witness points in the ITP pass unattended
- Material certificates and heat numbers are reconciled too late to act on
- Manufacturing slippage is reported to you as a delay, not as a warning
With PSPP at the source
You find out in the factory
An inspector with no commercial stake in the purchase order stands in front of the equipment while it is still being made.
- Nonconformities are raised while the equipment is still on the supplier's floor
- Release is recommended by an independent party, not by the party being paid to ship
- Every hold and witness point in the approved ITP is attended and recorded
- Certificates, heat numbers and test reports are verified against the purchase order
- Progress is expedited and reported early enough that the schedule can still be recovered
Inspection scope, standards and acceptance criteria are always agreed with you in advance and recorded in the Inspection and Test Plan.
What you can engage us to do
Five service lines, all of them verification work. Everything we offer sits inside our registered activity — technical testing and analysis — and inside the competence of the inspectors we can actually assign.
Documentation Review & Compliance
Review of quality and manufacturing records against project requirements — ITP/QCP, WPS/PQR/WPQ, material certificates, NDT records, and final dossiers, with traceability verification.
02Expediting & Progress Monitoring
Desk and field expediting that keeps equipment and materials on schedule — milestone verification, schedule monitoring, bottleneck identification, and progress reporting.
03QA/QC & Project Quality Support
Quality assurance and control support across the project — QA/QC supervision, quality surveillance, NCR/CAPA follow-up, and welding, coating, and E&I quality control.
04Technical Audits & Supplier Assessment
Independent assessment of supplier capability and quality systems — supplier and capability audits, process and quality-system audits, and project-specific compliance audits.
05Testing & Technical Verification
Witnessing and verification of factory and site testing — FAT/SAT, functional and performance tests, pressure testing, and NDT supervision — against approved procedures.
06Third-Party Inspection (TPI)
Independent third-party inspection of equipment at vendor works and project sites — from vendor and source inspection through in-process, final, and pre-shipment stages.

From your inquiry to the released report
The customer-facing half of our quality management system, in the order it actually happens.
- 1
Inquiry and requirement review
We log your inquiry and clarify the scope, location, applicable standards, ITP and schedule before quoting anything.
- 2
Feasibility and quotation
We check we can genuinely resource it — competence, availability and impartiality — then issue a quotation and review your order against it.
- 3
Inspector selection and approval
An inspector is selected internally or from our approved external network, and their CV, certifications, independence and confidentiality are verified for your job.
- 4
Coordination and execution
Access, safety, documents and dates are coordinated with the vendor, then the inspection, expediting or audit is performed and the evidence collected.
- 5
Report review and release
Every report is reviewed internally for completeness, accuracy and compliance before it is submitted to you — followed by feedback review and formal project closure.
Sectors we inspect for
The equipment changes; the discipline does not. These are the project types our inspection assignments have come from.
Agriculture
Storage, handling and drying equipment — silos, conveyors and structural steel supplied into agricultural and grain-handling projects.
Bioprocess Facilities
Bioreactors, fermenters and the clean utilities around them, where Pre-FAT coverage testing and dimensional verification precede Final FAT.
Data Centres
Power, cooling and containment equipment for data halls — switchgear, UPS systems, chillers and generator sets, usually on a compressed schedule.
Food Processing
Processing, filling and packaging lines — stainless fabrication and hygienic design verified before the line is shipped and commissioned.
Industrial Buildings
Structural steel, cranes and building services for plants and warehouses, inspected against structural welding and coating requirements.
Industrial Components
Valves, fittings, instrumentation, electrical panels and packaged units — high-count, multi-vendor scopes that need one consistent inspection standard.
Recent assignments, in the client’s own terms
Client and vendor identities are withheld — we publish the technical work, never the commercial relationship.
Featured Project
Bioreactor Pre-FAT and Riboflavin Coverage Testing — Slovenia
PSPP provided independent Pre-FAT inspection and expediting support for four stainless-steel bioreactor vessels manufactured for an international pharmaceutical expansion project.

Questions buyers ask us first
If yours is not here, ask it directly — the answer is usually short.
What is Third-Party Inspection (TPI) and why is it important?
Third-Party Inspection (TPI) is an independent verification service performed by a qualified inspection body that is independent of both the buyer and the seller. TPI is critical in industrial projects to ensure that equipment and materials conform to applicable engineering specifications, codes, and standards — protecting the client from receiving non-conforming equipment that could cause failures, delays, or safety incidents. PSPP acts as a neutral, independent TPI body operating a Quality Management System aligned with ISO 9001:2015.
What quality standards does PSPP inspect against?
PSPP's inspectors and engineers work to internationally recognized codes and project specifications — reviewing mill certificates, witnessing welding qualification and NDT results, and verifying dimensions and performance data against the manufacturing drawings and contractual requirements for each piece of equipment.
In which countries does PSPP operate?
PSPP is headquartered in Ljubljana, Slovenia, with Asia coordination offices in Xi’an, China and Changwon, South Korea. Our inspection coverage spans 61 countries across Europe & Eurasia, Asia, the Middle East, Africa, and South America — including markets such as Germany, Italy, Turkey, the UAE, Saudi Arabia, China, South Korea, and India. We mobilise qualified inspectors close to your suppliers, on short notice.
What is Expediting and how does it benefit my project?
Expediting is a proactive service that monitors supplier manufacturing schedules and resolves delays before they impact your project delivery dates. PSPP expeditors visit vendor facilities, track fabrication milestones, identify risks early, and work with suppliers to recover schedule slippage. This prevents costly project delays and keeps procurement on track.
What industries does PSPP serve?
PSPP specializes in serving the Oil & Gas, Petrochemical, Refinery, Power Plant, Pharmaceutical and general Industrial Plant sectors. Assignments are staffed with inspectors and approved external providers verified for the relevant discipline, standard and certificate requirements — including welding, NDT, mechanical, electrical and coating inspection — before assignment.
What is the difference between QA and QC?
Quality Assurance (QA) is a proactive, process-oriented approach that prevents defects by establishing and maintaining quality management systems, procedures, and audits. Quality Control (QC) is a reactive, product-oriented activity that identifies defects through inspection and testing. PSPP provides both: QA through supplier qualification, audit programs, and ITP development; and QC through hands-on inspection, testing witness, and dimensional verification.
