Off spec

A crude oil or refined product cargo is off spec if it does not satisfy the quality requirements set by contract or regulation.

Crude cargoes that are off spec are typically dealt with by a price adjustment.

Off-spec cargoes or batches of product must be brought back on spec, typically through adding a high-quality blend stock.
