SGS’s global network of analytical laboratories has specialized capabilities for independent party analyses and umpire assays of commercial settlement samples.

Construction detail

Party analyses (also known as commercial settlement assays) determine the quality of a commodity or cargo and thus its value and the payment due. The major or payable elements and all minor or impurity parameters are measured. Party assays use commodity specific methodology and require rigorous quality control steps.

Umpire assays are used to resolve a dispute between a buyer and seller. Samples of the parcel or cargo are analyzed in triplicate using established methods and quality control protocols to provide the highest level of accuracy and precision.

SGS has highly trained and professional staff with many years of experience handling complex samples. We employ uniform analytical and operational methodologies, follow industry-leading quality assurance and quality control practices, and use standardized documents for presentation of results.  Our professional experts from our global network collaborate closely to share best practices and expertise, ensuring we remain at the leading edge of technical developments. Partner with SGS for transparent, third-party party settlement and umpire assay services.
