Yes, corn is a commodity. Federal law says so directly: the Commodity Exchange Act lists corn among the enumerated agricultural commodities at 7 U.S.C. § 1a.1Office of the Law Revision Counsel. 7 USC 1a – Definitions That statutory classification is what allows billions of bushels to change hands each year through regulated futures exchanges, priced transparently and backed by federal quality standards. In practical terms, calling corn a commodity means it is a standardized, interchangeable good that can be bought, sold, hedged, and financed in bulk anywhere in the world.
Why Corn Qualifies as a Commodity
The trait that makes corn a commodity is fungibility. One bushel of a given grade is treated as identical to every other bushel of that grade, so a buyer does not have to inspect each truckload from each farm. A complex biological product gets reduced to a few measurable properties — test weight, moisture, kernel condition, color — and once graded, corn from Iowa is interchangeable with corn from Indiana.
That interchangeability is what turns a crop into a financial asset. Because every bushel of a particular grade is equivalent, contracts can represent large quantities of grain without being tied to specific physical lots. The value of the crop can be priced and traded independently of where it physically sits, which is why corn moves so easily between exchanges, grain elevators, ethanol plants, and livestock operations worldwide.
The USDA Grading System That Makes It Work
The grading standards behind that fungibility come from the USDA’s Federal Grain Inspection Service. Under 7 U.S.C. § 76(a), the Secretary of Agriculture sets official standards for corn covering quality, condition, and class.2Federal Register. United States Standards for Corn A purchase order can specify a grade, and both parties know exactly what physical properties come with it.
Yellow No. 2 is the benchmark. It is the delivery standard for futures contracts on the Chicago Board of Trade and the default for most commercial transactions. Under 7 CFR § 810.404, Yellow No. 2 corn must have a minimum test weight of 54 pounds per bushel, no more than 3.0 percent broken corn and foreign material, no more than 0.2 percent heat-damaged kernels, and no more than 5.0 percent total damaged kernels.3eCFR. 7 CFR Part 810 Subpart D – United States Standards for Corn
There are five numbered grades overall. U.S. No. 1 is the strictest, at 56 pounds per bushel minimum. U.S. No. 5 is the loosest, at 46 pounds per bushel with up to 10 percent broken corn and foreign material.3eCFR. 7 CFR Part 810 Subpart D – United States Standards for Corn Corn is also sorted into three color classes: Yellow, White, and Mixed.4United States Department of Agriculture. Subpart D – United States Standards for Corn Moisture matters too, because damp grain spoils in storage and transport. Corn delivered above the standard moisture level typically gets docked in price or has to be dried commercially, which cuts into net volume.
How That Status Shows Up in the Market
Because corn is a commodity, it trades as a standardized futures contract. Corn futures trade primarily on the Chicago Board of Trade under CME Group. Each standard contract represents 5,000 bushels of No. 2 Yellow corn, quoted in cents per bushel, with a minimum price movement of one-quarter cent, or $12.50 per contract.5CME Group. Chapter 10 Corn Futures A futures contract is a binding agreement to buy or sell that quantity of corn at a set price on a specified future date, giving producers and buyers a way to lock in prices months before harvest.
Entering a futures position requires posting margin, an upfront deposit that represents a fraction of the total contract value. If the account balance falls below a maintenance threshold, the trader gets a margin call and must add funds. Most corn futures positions are closed out financially before delivery by taking an offsetting position, though physical delivery remains available under the contract terms.6CME Group.

Basis: What the Farmer Actually Gets
The futures price is a national reference point, not the price a farmer receives at the local elevator. The gap between the two is called the basis. Basis reflects local supply and demand, transportation costs, and available storage. A farmer who tracks their local basis pattern can use the futures price to estimate what the crop will actually fetch at the elevator, which is what makes futures prices useful as planning tools even for producers who never trade a contract themselves.
Federal Oversight That Comes With the Classification
Corn’s status as an enumerated commodity puts it under the jurisdiction of the Commodity Futures Trading Commission. The CFTC’s authority flows from the Commodity Exchange Act, 7 U.S.C. § 1 et seq., which explicitly lists corn among the agricultural commodities subject to federal regulation.7eCFR. 17 CFR Part 1 – Definitions The CFTC registers and supervises the exchanges where corn trades, watches for manipulation, and enforces the rules meant to keep pricing transparent.
Fraud and manipulation in commodity markets are felonies, punishable by up to $1,000,000 in fines and up to 10 years in prison.8Office of the Law Revision Counsel. 7 USC 13 – Violations Generally; Punishment; Costs of Prosecution Civil penalties for manipulation exceed $1.48 million per violation, with lower amounts for non-manipulation violations, all adjusted annually for inflation.9eCFR. 17 CFR 143.8 – Inflation-Adjusted Civil Monetary Penalties
Position Limits Prevent Cornering the Market
To keep any one trader from cornering corn, the CFTC imposes federal speculative position limits. Under the final rule adopted in January 2021, a single trader may hold no more than 2,000 contracts in the spot month and no more than 15,000 contracts in any single non-spot month or across all months combined.10Federal Register. Position Limits for Derivatives At 5,000 bushels per contract, the all-months cap works out to 75 million bushels.
These limits target speculators, not producers. Farmers, grain merchandisers, and others who use futures to offset genuine commercial exposure in physical corn can apply for a bona fide hedging exemption. The applicant has to show real activity in the cash or swaps markets and demonstrate that the futures positions offset that commercial risk.11eCFR. 17 CFR 150.5 – Exchange-Set Speculative Position Limits and Exemptions Therefrom
Tax Consequences of Trading Corn as a Commodity
Because corn futures trade on a regulated exchange, they qualify as “Section 1256 contracts” under the Internal Revenue Code. That triggers two rules that don’t apply to ordinary investments. Open positions are marked to market on the last business day of the tax year, so unrealized gains and losses are taxed as if the contracts were sold that day. And all gains and losses on Section 1256 contracts are automatically split 60 percent long-term and 40 percent short-term, no matter how long the position was actually held.12Office of the Law Revision Counsel. 26 USC 1256 – Section 1256 Contracts Marked to Market
The 60/40 split is generally favorable, because long-term capital gains are taxed at lower rates. A trader who held a corn futures contract for only a few weeks still gets 60 percent of the gain taxed at the long-term rate. These gains and losses go on IRS Form 6781, which calculates the net figure and then allocates it to Schedule D.13IRS.gov. Gains and Losses From Section 1256 Contracts and Straddles (Form 6781)
One important limit: the 60/40 rule and mark-to-market treatment cover speculators and most financial traders. Farmers and grain businesses using futures to hedge their physical crop may instead qualify for hedging treatment under IRS regulations, which changes how the gains and losses are characterized. The line between hedging and speculation turns on the specific facts of the business, and picking the wrong treatment can create unexpected tax liability, so it is worth working through with a tax professional before filing.
