The very nature of a professional intermediary is to take care of consistency in quality because that is what keeps it in business. These agencies invest a lot in creating the checks and balances that ensure consistent quality. Their experts are familiar with the nitty-gritty of materials, machinery, production processes and have access to the latest in test equipment and inspection protocols. They are well versed in the processes of welding and heat treatment, for example, or the fabrication of reactors and pressure vessels, and the need to conform to the relevant international standards in terms of safety and end use certification. Above all, all these are spelled out clearly as part of the terms and conditions right at the outset.
