WAREHOUSE CONTROL & PERFORMANCE
Zone of Reasonableness
Zone of reasonableness describes a range of rates considered acceptable under a particular regulatory approach. Historical US rail discussions used it for latitude between rates considered too high or too low.
ZONE OF REASONABLENESS IN PRACTICE

- Review the standardRead the applicable rate test.
- Assess the real caseUse current official guidance.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
A concept without a universal percentage.
An old rail-rate discussion describes a zone of reasonableness. It does not establish that every modern freight rate must fall within a 25% or 50% band. The relevant law, facts and current process need to be examined before applying any threshold.
WHAT THIS MEANS FOR YOUR QUOTE
Agree the requirement before comparing quotes
Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.
