Third party inspection services for equipment and products

What third party inspection covers

Third party inspection means an independent inspector, working for neither the buyer nor the supplier, checks goods or equipment against the purchase order, drawings, specifications and agreed standards. It gives buyers evidence before they pay, ship or install, and gives suppliers an independent record that they delivered what was ordered.

Inspections are used in two broad areas. For industrial equipment and materials, such as pressure vessels, piping, steel structures, valves, pumps and electrical panels, inspectors review documents and witness key steps during manufacture. For consumer and industrial products made in series, such as textiles, furniture, electronics, tools and household goods, inspectors check quality at set stages of production against agreed criteria.

Each inspection ends with a written report, with photos and measurements, that states what was checked, what was found and whether the results met the agreed criteria.

• Pre-production inspection of materials and components
• During-production inspection of first output and processes
• Witness of factory acceptance tests, pressure tests and performance tests
• Review of material certificates, welding records and NDT reports
• Final inspection before shipment, with sampling where applicable
• Inspection reports with photos, measurements and clear results

The inspector works to your criteria. A good inspection starts with clear acceptance rules: tolerances, defect definitions, required tests and the documents the supplier must provide. Where these are missing, we help you put them on paper before the first visit.

Inspection types compared

A pre-production inspection checks raw materials, components and the readiness of the factory before mass production starts. It is the cheapest point to catch problems, because nothing has been built yet.

A during-production inspection checks the first finished units and the processes producing them, usually when a share of the order is complete. It finds systematic defects while there is still time to correct the rest of the order.

Vendor inspection for engineered equipment follows an inspection and test plan agreed between buyer and supplier, with hold points the inspector must attend, such as material identification, weld inspection, hydrostatic tests and final dimensional checks.

A final inspection checks finished goods before shipment. For series products this is often a random sample inspection, which we describe on our pre-shipment inspection page.

Document reviews can be done without a factory visit in some cases, for example checking material certificates, test reports and dossiers before shipment. They cost less but cannot replace seeing the goods when the risk is high.

What decides the price

Third party inspection with EUROTECH starts at $1,500. Your written quote shows exactly what is included for each visit.

• Type of inspection: production check, witness test or document review
• Number of inspector days and visits
• Location of the factory and travel
• Technical specialism required, such as welding or electrical inspection
• Report format and any specific client templates

Recurring inspection programmes for regular orders are usually planned as a schedule of visits, which makes each visit more efficient.

Clear purchase specifications lower cost too: inspectors work faster and give clearer results when the acceptance criteria are written down before the visit.

Inspections that need specialist skills, such as certified welding inspectors or electrical test engineers, usually cost more per day than general product inspections.

Reports can follow your own template if you prefer, which helps when several suppliers are compared.
