Grains & Oilseeds and Marine Transport Thereof: Definitions, Terms and Terminology

Updated: Oct 14, 2020


Terms, Terminology and Glossary for agricultural terms and marine inland barge transportation along the river-way system in the US.


1976 Benchmark Tariff Rates—The grain industry uses weekly barge rate quotes for southbound freight, based on the of the 1976 benchmark tariff rates per short ton at 7 locations on the inland waterway system. To calculate the barge rate per short ton, multiply the rate quote by the 1976 benchmark tariff rate per short ton for a point on the inland waterway system and divide by 100. Example: $3.99 (St. Louis 1976 benchmark tariff rate) times 200 percent (a sample rate quote), divided by 100 equals $7.98 per short ton. The 1976 benchmark tariff rates are from the Bulk Grain and Grain Products Freight Tariff No. 7, issued by the Waterways Freight Bureau (WFB) of the Interstate Commerce Commission (ICC). In 1976, the United States Department of Justice entered into an agreement with the ICC and made Tariff No. 7 no longer applicable, but the industry continues to use the 1976 tariff rates as a benchmark. The WFB no longer exists and the ICC has become the Surface Transportation Board of the United States Department of Transportation.

30-day to Arrive—Bids for grain for 30-day delivery to U.S. export ports in dollars per bushel. Also known as export bid.

AAR—Association of American Railroads

Atlantic—A grain export region that includes export elevators in Brunswick, GA, Albany, NY, and Chesapeake, VA.

Auxiliary Lock—The smaller chamber of a double lock that transfer vessels from one water level to another water level. The advantage of this two-lock facility is that both chambers can be working at the same time, and more importantly while one chamber is closed for repairs, the other chamber can handle the traffic. See Main Chamber Lock.

Barge—A general name given to flat-bottomed, rigged or unrigged, craft of full body and heavy construction, specially adapted for the transportation of bulk freight such as grain, ethanol, fertilizer, coal, lumber, oil etc. A barge load of grain, as a unit of measure is 52,500 bushels, or 1,500 short tons, equivalent to 15 jumbo hopper railcars or 58 large grain hopper semi-trailers. A jumbo covered hopper barge is the type of barge most frequently used for moving grain on the rivers.

Commodities Futures—Contracted price to purchase/sell commodities at a given rate and to be delivered at some point in the future.

Co-products in ethanol dry-grind—The water and solids remaining after distillation of ethanol is called whole stillage, comprised primarily of water, fiber, protein and fat. This mixture is centrifuged to separate coarse solids from liquid. The coarse solids are also called wet cake and contain about 35 percent dry matter. Wet cake can be sold to local cattle feeders without drying, or dried to produce dried distiller’s grains (DDG). The liquid, now called as thin stillage, goes through an evaporator to remove additional moisture and the resulting co-product is called condensed distiller’s solubles which contains approximately 30 percent dry matter. Condensed distiller’s solubles can be sold locally to cattle feeders. Alternatively, the wet cake can be mixed with condensed distiller’s solubles and dried to produce distiller’s dried grains with solubles (DDGS) which has 88 percent dry matter.

Container—An intermodal uniform, sealed, reusable metal “box” (generally 40 feet in length, able to hold about 40,000 pounds) in which merchandise can be moved by either, rail, barge, truck or vessel. The use of containers (or containerization) in trade is generally thought to require less labor and reduce losses due to breakage, spoilage, and pilferage, compared to more traditional methods of shipment. Containers come in 53, 48, 45, 40 and 20 foot lengths, and are anywhere between 8, 8.5, 9 and 9.5 feet in height. Width is eight foot.

Container Load—A load sufficient in size to fill a container either by cubic measurement or by weight.

Containerizable Cargo—Cargo that will fit into a container and result in an economical shipment.

Containerization—Stowage of cargo in a container for transport in the various modes. See Container.

Contract Rate—Rate and services that are specified in a shipper’s contract. A service premium and penalty may be assessed for non--performance by either the shipper or carrier.

Corn—Corn varieties include: U.S. No. 1-5 and Sample Grade, Yellow, White, and Mixed

Corn as defined by USDA's Grain Inspection, Packers and Stockyards Administration.

Corn #1—The highest grade of corn, distinguished by the highest minimum test weight, lowest moisture and foreign material, and the fewest damaged kernels. Marketed primarily as food.

Corn #2—Most frequently traded of all grades (about 60 percent of all corn sold), and the grade on which the traded price is based. It is used primarily for animal feed. Grades 3, 4, 5, and Sample are lower grades than #2. Sample Grade is the lowest grade available.

COT (Certificate of Transportation)—BNSF Railway’s program for offering guaranteed delivery of rail cars during specific periods.

Cover Crops—Grasses, legumes, and other forbs that are planted for erosion control, improving soil structure, moisture, and nutrient content, increasing beneficial soil biota, suppressing weeds, providing habitat for beneficial predatory insects, facilitating crop pollinators, providing wildlife habitat, and as forage for farm animals. Cover crops can provide energy savings both by adding nitrogen to the soil and making more soil nutrients available, thereby reducing the need to apply fertilizer.

Crop Year (CY)—Year in which a crop is harvested, as opposed to a marketing year, which refers to the 12-month period following harvest. See marketing year (MY).

Cross-border—Refers to land based movements of grain from the United States to Mexico or Canada.

Dried Distillers Grains with Solubles (DDGS)—In dry-grind ethanol production, it is Wet Distillers Grains (WDG) that has been dried with the concentrated thin stillage to 10–12% moisture. DDGS have an almost indefinite shelf life and may be shipped to any market regardless of its proximity to an ethanol plant. Drying is costly, as it requires further energy input. In the US, it is packaged and traded as a commodity product.

Deadweight Capacity—Capacity in metric tons is determined by deducting from total deadweight the weight of fuel, water, stores, dunnage, crew, passengers, and other items necessary for use on a voyage.
