Potato Market Intelligence
Potato Diameter Price Schedule
A potato diameter price schedule links commercial value to defined tuber-size bands under an explicit measurement method. MassGain connects premiums and discounts with regional size distribution, packout, end-use recovery, grade, variety, and delivery terms so size pricing remains comparable.
Market Data
How to read this market
A potato diameter price schedule maps premiums, base values, or discounts to defined tuber-diameter bands under an explicit sizing method. The market object is the price differential by size distribution, variety, region, grade, package, crop period, and delivery basis.
Use the data to compare supplier schedules with regional size availability and the buyer's actual end-use value. Preserve screen, measured diameter, tolerance, and off-size rules so schedules using different methods are not treated as equivalent.

Analysis
Why this matters
Size premiums depend on both crop distribution and end-use value. A large-potato premium is less defensible when large supply is abundant or when the buyer captures little incremental recovery from the bigger tuber.
Commercial interpretation should therefore pair the schedule with actual size availability and product economics. The same diameter band can carry different value in fresh, peeling, fry, or institutional channels.
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 procurement and market-intelligence teams that need a defensible potato diameter price schedule. MassGain connects size bands with observed market prices, packout, end-use demand, grade rules, freight, and supplier terms so buyers can see how value changes as tuber diameter moves above or below a commercial threshold.
The suite preserves the original sizing method—such as minimum diameter, maximum diameter, count range, or screen size—and prevents unlike schedules from being blended. Users can compare supplier premiums and discounts, test whether a requested adjustment is supported by current size availability, and understand how crop profile, variety, and regional packout affect the spread between small, medium, and large potatoes.
Procurement can normalize bids, finance can forecast mix-driven cost, and operations can match size economics with product recovery. MassGain does not certify grade or prescribe a schedule. It provides a transparent framework for translating physical size distribution into auditable commercial pricing.
Use Case
A foodservice buyer receives a quote with premiums for potatoes above 3.25 inches and discounts below 2.5 inches. MassGain compares the schedule with regional size distribution, packout, freight, and the buyer's actual usage mix. The team negotiates a narrower premium because large-size supply is ample and the operation does not capture enough additional yield to justify the full increase.
FAQs
What is a potato diameter price schedule?
It is a table of premiums, base prices, or discounts tied to defined tuber diameter bands.
Why must the sizing method be explicit?
Screen size, minimum diameter, count, and measured diameter can produce different commercial comparisons.
How does MassGain test a size premium?
It connects the requested adjustment with regional size availability, end-use value, packout, and comparable transactions.
