Last updated: August 2026 dataCrude oil is the single largest commodity by value in US goods trade, and its classification under this heading covers unrefined petroleum oils as well as oils extracted from oil sands, oil shale, and other bituminous minerals in their crude state. API gravity and sulfur content — the two primary quality axes that define light/heavy and sweet/sour grades — determine refinery suitability and pricing differentials, making accurate quality certification essential for commercial and customs purposes. The US imports crude from a geographically diverse set of suppliers, and origin documentation is particularly important given that certain producing countries have been subject to sanctions or trade-remedy scrutiny.

API gravity determines whether a crude is classified as light (typically above 31.1° API) or heavy, while sulfur content distinguishes sweet (below 0.5% sulfur) from sour grades. These parameters drive refinery configuration requirements, pricing benchmarks (e.g., WTI, Brent, Maya), and in some cases pipeline tariff eligibility. They are declared on the bill of lading and certificate of quality and are the primary basis for commercial dispute resolution.
Country of origin for crude oil is established through a combination of the certificate of origin issued by the exporting country, the bill of lading, and in some cases a certificate of quality identifying the crude stream. Origin is particularly scrutinized when crude has been blended, transshipped, or processed in an intermediate country, as substantial transformation rules and sanctions compliance both depend on accurate origin determination. Importers should work with a licensed customs broker and legal counsel when origin is ambiguous.
