Does EIA have data on the type or quality of crude oil?

The U.S. Energy Information Administration (EIA) publishes data on the quality of crude oil produced in the United States:

EIA also publishes the sulfur content and API gravity of crude oil imported into the United States, along with the volume, source country, and name of the processing facility (refinery) that received the oil, in the data file for the Company Level Imports. Columns M and N in the data file have the sulfur and API gravity data. EIA’s crude (oil) imports tracking tool contains data on crude oil imports by crude oil grade.
