Corn trades across feed, food, starch, ethanol and other industrial channels, with physical value shaped by grade, colour or type, moisture, test weight, damage, toxins, origin and delivery terms. CBOT corn is a reference contract, not a universal delivered price.
This release uses current CME corn contract specifications and USDA official corn standards. It reports stable contract and grade definitions rather than a live cash price or unsupported crop total.
Commodity corn should not be merged with sweet corn, seed corn or processed maize products. A physical record names yellow, white or other contractual type; grade; crop year; GMO or identity-preserved status where relevant; and intended feed, food or industrial use.
USDA corn grades use factors such as test weight, damaged kernels, broken corn and foreign material. Commercial contracts may also set moisture, mycotoxin, odour, pesticide-residue, fumigation and food- or feed-safety requirements. Each limit needs its sampling and test basis.
CME defines CBOT corn in 5,000-bushel contracts quoted in cents per bushel. A physical offer requires origin, grade and differential, quantity, currency, Incoterm, load point or destination, delivery window, freight and dated evidence before a delivered value can be compared.
No. It is a reference-market contract. A delivered physical price additionally needs grade, origin, basis, Incoterm, destination, freight and delivery timing.
CME specifies 5,000 bushels, approximately 127 metric tons.
Common controls include grade, test weight, moisture, damaged kernels, broken corn and foreign material, plus contractual toxin and safety limits.
Type and grade, crop year, GMO status where relevant, test weight, moisture, damage, toxins, quantity, currency, origin, Incoterm, destination, delivery window and evidence date.
Figures retain their source, period and review date. Corroboration is not promoted to primary evidence.
