Potato Market Intelligence
Potato Price by Size
Potato price by size compares values for defined count, diameter, weight, or processing-length categories within matched physical markets. MassGain connects size premiums with crop distribution, packout, end-use demand, customer specifications, alternate origins, and substitution options so users can isolate size-specific scarcity.
Market Data
How to read this market
Potato price by size compares values for defined count, diameter, weight, or processing-length categories within the same origin, variety, grade, package, crop period, and delivery basis. The object should preserve the size convention because retail counts, processing lengths, and diameter bands describe different commercial markets.
Use size prices with crop size distribution, packout, end-use demand, customer specifications, and alternate origins. This shows whether a premium reflects genuine scarcity in one size class or a broader potato-market move and whether substitution can reduce delivered cost.

Analysis
Why this matters
A crop can be abundant in total weight while one commercially important size is scarce. Large baking potatoes, petite retail packs, and long processing tubers can therefore move independently. The decision signal comes from the intersection of size distribution and buyer flexibility: a premium matters only to customers that truly require that size.
Signal 01
Usable Crop Uncertainty Index
UCUI translates crop and market complexity into a simple uncertainty signal. Higher readings indicate greater uncertainty—not necessarily higher prices.
Understand uncertainty. Anticipate risk. Act earlier.
UCUI is designed to analyze potato-industry publications and data signals across regions, varieties, weather, disease, storage, supply, and demand.

Potato market steady for now; Russia’s smaller crop is the salient risk
Spot prices are flat and USDA terminal reports read ‘market steady,’ but a renewed forecast for a smaller Russian harvest and recent regional harvest stress leave seasonal import timing and storage losses as the key uncertainty.

Overview
Who is this for?
This page is for distributors, packers, processors, restaurant buyers, retailers, and procurement teams that need potato prices separated by size. Size-level pricing matters because tuber dimensions influence package yield, culinary use, cut recovery, processing performance, customer specification, and the volume available from a particular crop.
MassGain compares matched size categories within the same origin, variety, grade, package, crop period, and delivery basis. This reveals whether a premium reflects genuine scarcity, customer demand, or a temporary size-distribution problem. A crop can be abundant in total tonnes while large baking counts, petite retail potatoes, uniform canning sizes, or long processing tubers remain tight. The platform connects size prices with crop distribution, packout, historical spreads, alternate origins, and end-use economics.
The analysis supports supplier negotiation, package planning, menu flexibility, plant allocation, and customer pricing. Buyers can determine whether to pay the premium, substitute another size, change the package, or preserve scarce product for the accounts that value it most. MassGain does not establish official size standards or guarantee substitution. It supplies the market context needed to understand which size is setting price and whether a different specification can lower delivered cost without harming product or customer performance.
Use Case
A foodservice distributor faces a large premium for 70-count russets. MassGain shows 90-count supply is plentiful from the same origin and several customers can accept the smaller size. The buyer reserves scarce 70-count cartons for strict accounts and shifts flexible volume, limiting the systemwide increase.
FAQs
Why do potato prices vary by size?
Crop size distribution, end-use suitability, package demand, processing recovery, and customer specifications create distinct markets.
Can another size substitute for a shortage?
Sometimes, when culinary, processing, package, and customer requirements allow the change.
How does MassGain compare size markets?
It aligns origin, variety, grade, package, crop period, and delivery basis and adds historical spread and availability context.
