Potato Market Intelligence
Potato Storage Stocks as of First of Month
Potato storage stocks as of first of month provide a dated view of remaining inventory by region, use, quality, and ownership. MassGain separates nominal tonnes from merchantable and committed stocks and connects each snapshot with withdrawals, shrink, inspections, and new-crop timing.
Market Data
How to read this market
Potato storage-stocks-as-of-first-of-month data records monthly inventory snapshots by region, facility, owner, variety, grade, crop use, and reporting definition. The market object is the dated storage position, with merchantable, committed, seed, processing, fresh-market, and impaired stocks separated where possible.
Use the data to compare seasonal depletion, withdrawals, shrink, inspections, and new-crop transition while preserving survey date, publication lag, coverage, and revisions.

Analysis
Why this matters
A first-of-month stock total can look comfortable while freely available premium supply is tight because quality, ownership, contracts, and end use narrow the usable pool.
Commercial interpretation should normalize for crop size and distinguish total tonnes from merchantable and accessible inventory.

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 and wholesalers using potato storage stocks as of the first of the month to assess remaining physical supply. MassGain aligns monthly inventory observations by region, facility, owner, variety, grade, crop use, storage type, and reporting definition.
It separates total tonnes from merchantable, committed, seed, processing, fresh-market, and quality-impaired stocks and links the snapshot with prior withdrawals, shipments, shrink, inspections, and new-crop timing. Users can compare the current month with historical seasonal curves, identify where depletion is faster or slower, and determine whether nominal stocks remain commercially accessible. Distributors can plan releases and customer coverage, procurement can assess late-season risk, finance can value inventory, and analysts can estimate disappearance.
The suite preserves survey date, publication lag, revisions, and coverage so monthly snapshots are not treated as exact real-time inventories. MassGain does not replace physical counts or certify quality. It provides a transparent stock-position framework that helps users understand what remains, where it is held, and how much may be usable through the next demand period.
Use Case
A region reports first-of-month stocks above last year. MassGain adjusts for a larger crop, slower quality-adjusted withdrawals, and more contracted inventory. The freely available premium-grade position is actually tighter, so a wholesaler protects late-season customer coverage.
FAQs
What does first-of-month storage stock measure?

Why distinguish total and merchantable stocks?
Quality, contracts, seed needs, ownership, and storage loss determine how much inventory can serve the market.
How does MassGain compare seasons?
It aligns crop size, date, region, use, reporting coverage, withdrawals, and quality condition.
