Agri Supply Chains, Traceability and Food Exports

How an agricultural supply chain works

Every farm product passes through roughly the same stages. Inputs such as seed, fertilizer and feed come in; the farm grows the crop or raises the animals; the harvest is gathered at a first collection point (a grain elevator, packhouse, dairy plant, gin or mill); it’s processed, stored and graded; and it moves through wholesalers and distributors to retailers, restaurants or export buyers. Each handoff is a point where value is added, where quality can slip and where records can get lost.

How that chain is run depends mostly on how long the product keeps. Grains, oilseeds and cotton can be stored for months, pooled from many farms and traded as commodities. Fresh fruit, vegetables, milk and meat have days or weeks, so they need a cold chain from field to shelf and tight scheduling at every step. Our overview of agriculture supply chain solutions looks at the tools used at each stage.

The agriculture supply chain in the USA

In the United States, bulk crops travel a well-worn route. Grain and soybeans go by truck from the farm to a country elevator, then by rail or by barge down the Mississippi and its tributaries to export terminals on the Gulf, or by rail to the Pacific Northwest for shipment to Asia. Fresh produce from California, Florida, Arizona and Mexico moves mostly in refrigerated trucks to distribution centers across the country. The USDA’s Agricultural Marketing Service tracks this movement and publishes a weekly Grain Transportation Report covering rail, barge, truck and ocean freight.

The weak points show up when one link is squeezed: low water on the Mississippi that limits barge loads, a rail service problem at harvest, a shortage of truck drivers or refrigerated containers. Our guide to agricultural logistics costs and tools walks through truck, rail and barge costs, and the piece on California agricultural exports shows what moves out of the largest farm state.

Food traceability rules and records

Traceability means being able to say where a product came from and where it went, fast enough to matter in a recall. In the US, most food businesses have long had to keep records one step back and one step forward. The FDA’s Food Traceability Rule under the Food Safety Modernization Act goes further for foods on its Food Traceability List, such as leafy greens, fresh-cut fruit and vegetables, shell eggs and some seafood, requiring specific records at each critical tracking event. The FDA has said it won’t enforce the rule before July 20, 2028, following a directive from Congress (FDA).

Paper and spreadsheets break down as the number of farms and lots grows, which is where software comes in. A shared digital ledger such as a blockchain lets each party add its records without being able to change anyone else’s. Our agricultural traceability software uses a Hyperledger Fabric ledger, RFID tagging and farm-level QR codes, and we ran a two-year cotton traceability project with a German textile client. Our explainer on blockchain food traceability covers how it works and what it costs to build.

Deforestation rules and the EUDR

The EU Deforestation Regulation (Regulation (EU) 2023/1115, amended by Regulation (EU) 2025/2650) covers cattle, cocoa, coffee, oil palm, rubber, soya and wood, plus products made from them. Companies placing them on the EU market have to collect the geolocation of every plot where the commodity was produced and show it wasn’t deforested after 31 December 2020. Under the amended timeline, the rules apply from 30 December 2026 for large and medium operators and from 30 June 2027 for micro and small ones (European Commission). Check the Commission’s site for any later changes before you plan around these dates.

For exporters, the practical work is building a plot register: boundaries for each farm, checked against satellite imagery from before and after the cutoff, linked to the lots that leave each farm. That evidence backs the due diligence statement an operator files in the EU information system before the goods go on the market. Our traceability software includes EUDR compliance reports built on that kind of farm-level record.

Exporting farm products

Exporting adds paperwork on top of logistics. The buyer’s country sets the rules on grades, labels, residue limits and plant or animal health, and most fresh produce, grain and plant products need a phytosanitary certificate, issued in the US by USDA’s Animal and Plant Health Inspection Service, saying the shipment has been inspected and meets the importer’s requirements. Contracts spell out who pays for freight and insurance and where the risk passes to the buyer, usually with an Incoterm such as FOB or CIF. Our guide to the agricultural export process goes from on-farm grading to the ship, and the Canada agriculture exports piece shows how one major exporter’s trade is changing.
