Seed Potato Conditional Defect Tolerance
Seed potato conditional defect tolerance records a limited exception that applies only under defined conditions. Growers and inspectors can preserve why a lot was accepted, held, sorted, or scheduled for reinspection without turning the exception into a blanket allowance.
Market Data
How to read this market
Seed-potato conditional-defect-tolerance data records a limited defect allowance that applies only under defined conditions, such as defect type, severity, sample basis, current lot condition, intended use, or certification program. The market object is the inspected lot together with the exact exception being applied.
Use the data to preserve why a lot was accepted, held, sorted, or scheduled for follow-up, and to compare the defect with storage history and destination requirements. The tolerance should travel with its conditions rather than become a blanket allowance for other lots.

Analysis
Why this matters
Conditional tolerances matter because a borderline defect can have different consequences depending on severity, progression, storage time, and planting use. The same observed incidence may be acceptable in one context and risky in another.
Commercial interpretation should separate a controlled exception from a weakening quality trend. If the underlying condition is changing, reinspection can matter more than the original tolerance.

Overview
Who is this for?
This page is for seed potato growers, buyers, inspectors, and certification teams that need to interpret conditional defect tolerance. A conditional tolerance allows a limited defect level under stated circumstances, often depending on severity, marketability, treatment, intended use, or whether the defect is progressive. MassGain helps users apply the correct rule to the correct lot without turning an exception into a blanket allowance.
The suite can organize defect type, severity, incidence, sample size, lot identity, inspection date, storage condition, destination, contract terms, and certification program. Growers can determine whether a lot remains eligible for sale, requires sorting, or should be redirected. Buyers can compare the accepted tolerance with planting risk and expected field performance. Inspectors can preserve the basis for the decision and track whether the condition worsens over time.
Conditional tolerance requires context and current evidence. MassGain does not determine legal eligibility or replace inspection judgment. It provides a transparent record that links the exception with the exact defect, lot, conditions, and commercial consequences, helping teams avoid inconsistent decisions and identify when reinspection or further handling is needed.
Use Case
A certified seed lot shows a borderline level of mechanical damage that may be acceptable if pieces remain sound. MassGain links the inspection sample, storage history, defect severity, and destination requirements, allowing the buyer to accept the lot with documented conditions and a follow-up check before planting.
FAQs
What is a conditional defect tolerance?
It is a limited allowance that applies only under defined conditions, defect types, and program rules.
Why must severity be recorded?
Minor and severe defects can create very different planting, storage, and certification risks.
How does MassGain preserve the decision?
It links the tolerance, inspection, defect, lot, destination, conditions, and follow-up actions.
