The NOPA Monthly Crush Report aggregates soybean crush reported by members of the National Oilseed Processors Association, a United States trade group.
The group was organized in 1930, and the report is a member census, not a government survey. Its publisher page cites data from 20 member companies covering 99% of the United States soybean crush. A January 2013 announcement cited 12 members running 57 plants in 19 states, about 95% of processing.
Each Statistical Report prints quantities only, with no prices, forecasts or commentary. It is not total United States crush, since non-members are excluded; the full industry count is the USDA Oilseed Crushings report about two weeks later. It does not measure bean production, farm stocks or whole-bean exports. The Bureau of Labor Statistics publishes no such report.
