Wheat is traded by class, grade and end use—not as one interchangeable grain. Milling wheat, feed wheat, soft and hard classes require different protein, test-weight, defect and functional specifications, while futures remain reference instruments rather than delivered physical offers.
This release uses current CME Chicago SRW contract specifications and official USDA grain standards. Contract quantities are reference-market definitions, not a live physical quote or a global crop estimate.
Chicago SRW is one reference-market contract, not a definition for all wheat. A physical lot should name class or variety, crop year, official or contractual grade, milling or feed use, protein basis, test weight, moisture, falling number where relevant, defects and contamination limits.
CME defines a 5,000-bushel Chicago SRW contract quoted in U.S. cents per bushel. A physical export offer adds origin, elevation or loading point, quality differentials, quantity, currency, Incoterm, destination and shipment window. Atlas keeps those layers separate.
USDA grain standards provide official grade architecture, while contracts may add buyer-specific requirements. Procurement evidence can include inspection certificates, phytosanitary documents, certificates of origin, fumigation or treatment records, weight evidence and testing methods tied to the lot.
No. It is a Soft Red Winter reference contract. Physical wheat varies by class, grade, protein, origin, quality differential, Incoterm and delivery period.
CME specifies 5,000 bushels, approximately 136 metric tons.
Different classes have different protein, hardness and functional properties, which affect milling, baking, feed use and commercial value.
Class or variety, crop year, grade, protein basis, test weight, moisture, defects, quantity, currency, origin, Incoterm, destination, shipment window and evidence date.
Figures retain their source, period and review date. Corroboration is not promoted to primary evidence.
