Idaho is the undisputed #1 US potato-producing state. The 2025 crop hit 138.4 million hundredweight on 313,000 planted acres — about 33.6% of the entire US potato crop of 412 million cwt (USDA NASS Crop Production Report, November 2025). Per-acre yields average 450+ cwt, the highest in the country. Roughly 75% of Idaho's volume moves to processing — frozen french fries, hash browns, tater tots, dehydrated, and chips — while the remaining 25% ships fresh-pack to retail.
A single Lamb Weston plant in American Falls or Boardman OR can tender 50+ truckloads of finished frozen product per day. J.R. Simplot ships continuously from Caldwell, Pocatello, Burley, and Aberdeen. McCain Foods runs Burley ID and Othello WA. Together with Cavendish Farms, these four processors control more than 95% of US frozen potato sales.
Evergreen Shippers (FMCSA MC#896325) is the Spokane-anchored transportation broker that dispatches the trucks. We handle the bulk bin reefer at 45–50°F for fresh storage moves, the 53-foot frozen reefer at continuous -10°F for finished french fry distribution to QSR DCs, the walking floor for cull and processing byproduct, and the ventilated van for cold-weather storage moves. Year-round dispatch — not just dig season.
We do not hold a PACA license, do not take title to potatoes, and do not negotiate produce sales. The potato shipper or processor retains the PACA-licensed sales relationship. Evergreen's role is freight execution — carrier capacity, dispatch, cold chain integrity, and on-time DC delivery.
Fresh potato storage and transit setpoint is 45 to 50°F. Storage below 40°F causes cold sweetening — the starch in the tuber converts to sugar, which causes dark fry color and is a processing defect. A reefer instructed at apple temperatures (32–34°F) ruins a fresh potato load. Carrier briefing and rate-confirmation setpoint matter.
Three Idaho production zones plus two Washington-side adjacent markets. Each has its own crop profile, processor footprint, and freight rhythm.
Bingham, Bonneville, Madison, Jefferson, Fremont, Power, and Bannock counties. Anchored by Idaho Falls, Blackfoot, Pocatello, Aberdeen, and Rexburg. This is the heart of the Russet Burbank belt — the variety that built Idaho's processing dominance. Freight tenders cluster around Idaho Falls outbound and the processor plants at American Falls and Aberdeen.
Twin Falls, Jerome, Gooding, Minidoka, and Cassia counties. Burley, Rupert, and Twin Falls are the freight hubs. Magic Valley is dense with processing plants — Lamb Weston Twin Falls and American Falls, McCain Burley, J.R. Simplot Burley. NewCold Burley operates one of the largest automated cold storage facilities in the region, primarily serving Lamb Weston.
Canyon, Payette, Owyhee, and Washington counties. Caldwell, Parma, Nampa, and Ontario OR. J.R. Simplot HQ is in Boise; the Caldwell processing plant anchors the area. Treasure Valley grows a more varied crop mix than the Snake River Plain — processing russets, fresh-pack varieties, seed potato, and yellows/reds.
Franklin, Grant, Benton, and Adams counties in Washington. Pasco, Othello, Quincy, Connell, Moses Lake, and Royal City. Washington produces about 120 million cwt of potatoes annually — the #2 US state. McCain Othello, J.R. Simplot Moses Lake / Othello, and (until October 2024) Lamb Weston Connell ran here. Mirror freight lanes to ID, with shorter transit times to PNW retail DCs.
Mount Vernon-anchored Skagit Valley supplies approximately 95% of Washington's red and specialty potato output. Different harvest calendar than the russet zones — a cooler maritime climate produces tighter-skinned, brighter-red product. West-side reefer lanes to Pacific Northwest and California retail DCs dominate the freight rhythm. Skagit also grows world-class seed crops (cabbage, beet, spinach seed) which is a different freight book.
Four firms control more than 95% of US frozen potato sales. Their plants drive an enormous share of regional freight volume.
Founded 1929. Major frozen french fry and dehydrated lines. Plants at Caldwell ID, Pocatello ID, Burley ID, Aberdeen ID, plus Moses Lake WA, Hermiston OR, and Othello WA. New plant under construction with planned 2026 commissioning. Simplot is a primary McDonald's supplier alongside Lamb Weston.
Plants at American Falls ID, Twin Falls ID, Boardman OR (the largest), Hermiston OR, Quincy WA, Pasco WA, Richland WA (Tri-Cities). Connell WA plant closed October 2024 as part of Lamb Weston restructuring. The world's largest frozen potato processor — supplies McDonald's, Burger King, regional QSR. A single major plant tenders 50+ truckloads/day of finished product.
US plants at Burley ID, Othello WA, Plover WI, and Easton ME. Supplies QSR and foodservice channels. McCain runs both frozen french fry and specialty product lines (formed/coated fries, hash browns).
Jamestown ND plant serves the broader US market. Smaller US footprint than the big three but a meaningful share of frozen french fry and hash brown distribution.
Idahoan Foods — Lewisville ID and Idaho Falls ID. The world's largest dehydrated potato manufacturer (mashed potato flakes, hash brown granules, instant mashed). Frito-Lay chip-grade potato slip-stream draws from Columbia Basin and Idaho. Snake River Plain Foods, Sun-Glo, Magic Valley Quality Milk — specialty processors with niche freight profiles.
Fresh-pack runs about 25% of Idaho volume — the slice that tenders open-market 53-foot reefer loads to retail DCs and foodservice. The packers below originate the majority of Idaho fresh potato freight.
Wada Farms (Pingree ID — fresh, chipping, organic). Potandon Produce (Idaho Falls ID — "Klondike Brands" — the largest fresh potato marketer in the US). Eagle Eye Produce (Idaho Falls ID). Pleasant Valley Potato (Aberdeen ID — fresh and seed). Plain Spuds (Idaho Falls). Sun-Glo of Idaho (Sugar City ID). Walters Produce / Walt Bex & Sons. J.D. Heiskell (feed and byproduct streams). Floyd Wilcox & Sons (Rupert ID). Driscoll Potatoes. Spudnik Equipment Company (Blackfoot ID — fresh-pack and bin handling equipment manufacturer; generates inbound steel/component freight).
Most agricultural commodities run a single-stage origin-to-destination pattern. Idaho potatoes run a multi-stage flow — field through cellar storage, splitting into processing and fresh-pack streams, then through cold storage to the final receiver.
Flow synthesized from Lamb Weston Holdings 10-K (FY2024), Simplot corporate disclosures, Idaho Potato Commission storage reports, and USDA AMS Federal Marketing Order 945 (Idaho/Eastern Oregon potatoes).
24–26 bins per trailer, 900–1,000 lbs each (~22–26,000 lbs payload). Used for fresh-storage bulk movement and processor inbound where the carrier is not on a processor-owned dedicated fleet. Setpoint 45–50°F with 90–95% relative humidity.
Continuous-run frozen reefer for finished french fries, hash browns, tater tots, and formed product. 5–7 day cross-country runs (Idaho to East Coast) require fuel monitoring, reefer download data, and dual-driver teams on premium QSR commitments.
Live-floor trailers for cull potatoes, processing sludge, peel waste, and other byproduct streams. Not standard reefer fleet inventory — capacity tightens around processor plants when multiple lines run simultaneously. Recurring spot-market problem that benefits from broker network depth.
For fresh-pack 50-pound cartons or 10-pound bags to retail DCs. ~46–48,000 lbs payload, set 45–50°F. The open-market workhorse for the 25% of Idaho volume that runs fresh.
For storage moves during the cold-weather months when ambient is acceptable and refrigeration is unnecessary. Cost-saver for storage-pulled product on short-to-medium hauls Oct–March.
For mixed loads pairing frozen french fries with chilled product, or fresh potatoes with WA apples / Treasure Valley onions / dairy on consolidated multi-stop dispatches. Independent setpoints per compartment via moveable bulkhead.
Idaho's freight rhythm is not driven by harvest timing — it is driven by storage. The state operates hundreds of climate-controlled cellars holding potatoes at 45–50°F and 95% relative humidity. The September–October dig fills cellars; outbound shipping continues through the following August.
Long-term hold (6–9 months or more) requires sprout inhibitor. CIPC (chlorpropham) has dominated industry practice for decades, applied as an aerosol mist into sealed cellars. CIPC is under regulatory pressure — the EU banned it in 2020 and US regulatory scrutiny is rising. Maleic hydrazide, applied in the field during late tuber bulking, is the growing alternative.
Cellar ownership is fragmented: grower-owned cellars selling to processors or fresh shippers, processor-controlled cellars (Simplot and Lamb Weston run long-term grower-supply contracts), and shed-controlled cellars at the fresh packers. The freight implication: tenders come in every week of the year. Demand spikes around the post-Labor Day school foodservice ramp, October–November new-crop fresh pull, December holiday volume, the March–April storage clears, and the summer storage tail.
Five major lane categories run out of Idaho. Frozen french fry is the highest-volume long-haul category — cross-country to QSR DCs — while fresh-pack runs shorter West Coast distances.
| Lane (Origin → Destination) | Primary Mode | Typical Transit |
|---|---|---|
| American Falls / Twin Falls / Boardman → National QSR DCs (Dallas, Atlanta, Charlotte, NJ/PA, FL) | 53' frozen reefer (-10°F) | 4–7 days, dual-driver on premium lanes |
| Idaho Falls / Burley → PNW retail/club (Walmart Olympia, Costco Sumner, Fred Meyer) | 53' reefer 45–50°F or frozen | 1–2 days |
| Idaho Falls / Aberdeen → California (Mira Loma, Tracy, Compton) | 53' reefer 45–50°F | 2–3 days |
| Snake River Plain → Texas QSR (Dallas, Houston, San Antonio) | 53' frozen reefer (-10°F) | 3–4 days |
| Snake River Plain → Northeast / Mid-Atlantic (PA, NJ, NY) | 53' frozen reefer or reefer intermodal | 5–7 days OTR / 7–9 days IMC |
| Treasure Valley → Mexico seed potato (cross-border) | 53' reefer or ventilated van | 2–3 days + USDA APHIS / SENASICA |
| Columbia Basin WA → PNW retail / mirror ID lanes | 53' reefer 45–50°F or frozen | Shorter haul vs ID origin |
| Skagit Valley WA → West Coast retail (red/yellow specialty) | 53' reefer 45–50°F | 1–3 days |
Lane distances and modes from DAT Freight & Analytics 2025 reefer rate index and lane benchmarks. National DAT reefer averaged $2.47/mi October 2025 and reached approximately $3.13/mi through April 2026 (+25% YoY).
Idaho frozen french fry freight terminates at specific QSR distribution networks — not at the QSR restaurants themselves. Knowing the network matters for appointment scheduling and compliance.
Idaho ships every week of the year, requiring carrier networks built for 52-week consistency rather than seasonal surge. Many produce-focused brokers can't deliver reliable capacity outside harvest.
Carrier rolodex weighted toward year-round reefer capacity, not just produce-season specialists. PNW asset-based sister fleet for continuity.
Bulk bin pickup demand spikes during dig; rain delays compound; reefer + flatbed + walking floor demand collide. Many shippers find capacity disappears mid-dig.
We work with returning shippers ahead of dig start to scope carrier capacity against expected weekly tender volume.
Fresh potato setpoint is fundamentally different from apple, cherry, or berry setpoint. Carriers crossing produce categories sometimes default to the colder setpoint, ruining the load via cold sweetening.
Reefer setpoint, continuous vs. cycling run, and humidity target are explicit on every potato rate confirmation. Pre-cool verified before pickup.
QSR distribution OTIF penalties are often stricter than retail. 5–7 day cross-country at continuous -10°F demands fuel monitoring, reefer download data, and dual-driver teams on premium lanes.
Appointment confirmed against carrier ETA. Dual-driver dispatch on premium QSR lanes. Reefer download data available on request for QSR cold-chain audits.
Walking floor capacity around processor plants tightens when multiple lines run. Not standard reefer fleet inventory — spot-market shopping load-by-load is the typical workflow.
Carrier network built specifically for byproduct outbound. Recurring tender capacity rather than load-by-load shopping.
DAT national reefer index ran up ~25% YoY through April 2026. Long-haul Idaho-to-East-Coast frozen french fry economics are tighter than the 2024 baseline.
DAT lane-level data plus committed-capacity rates. Honest pricing rather than stale assumptions. Continuous-move bundling for carriers protects rate stability.
