Third Party Inspection (TPI)
Independent verification that equipment and materials conform to code, before, during and after manufacture.
What is Third Party Inspection?
Third party inspection (TPI) is the independent verification of a product or service against international standards and client requirements, carried out by a party with no commercial stake in the outcome. Every supply involves three roles: the first party (the seller or supplier), the second party (the buyer), and the third party — an independent inspection body appointed by the buyer to confirm conformity on its behalf.
The value of third party inspection rests entirely on impartiality. Arotec Quality holds no role in the design, procurement, manufacture or installation of the items we inspect — our only interest is an accurate result. Our inspections follow rigorous internal quality procedures and documented reporting protocols, giving each client a clear, defensible record of conformity at every hold point.
Building on a heritage in demanding oil & gas and energy projects, Arotec Quality combines genuine sector expertise with a European network of over 100 qualified specialists and established cooperation with leading certification bodies including TÜV NORD, TÜV Rheinland, SGS, DNV and Lloyd's Register — acting as your eyes and ears at every link in the supply chain.
