Inspection
SGS
SGS — the largest third-party inspection company for physical oil cargoes.
SGS is the world's largest inspection company. In physical oil trade, SGS (or peers Intertek, Bureau Veritas, Cotecna) confirms quantity, quality, and documentation at the load port, discharge port, or both.
An SGS Q88 (vessel questionnaire) and quantity-quality certificate are non-negotiable for any serious cargo — LCs typically require SGS certificates as a payment document.
OilFlow's inspection-comparison parser extracts load-port vs discharge-port Q88 data with Claude Opus vision and flags quantity drift >0.5%.
