What is Domestic Sweet Blend crude?

Domestic Sweet Crude Oil is the CME (NYMEX) benchmark conventionally produced light sweet crude offered for contract sale at Cushing, OK.

Domestic Sweet is a fully blended aggregate of many feeder streams and only begins its existence in blend tanks in Cushing, OK. It is often confusingly referenced on crude price reports as West Texas Intermediate (WTI), which in fact is one of the feeder streams to Domestic Sweet Crude Oil.

Existing contract quality requirements are listed in the NYMEX Rulebook Section 200. The COQA has proposed the addition of the attached specifications to CME Section 200.
