The specification is not one document, it is one per market
The same commodity is a different product in three destinations
A container of chilli, rice or table grapes going to Rotterdam, Osaka and Jebel Ali is subject to three different sets of rules about what may be present in it and at what level. Residue limits for the same pesticide active differ by market and are revised. Treatments accepted in one destination are prohibited in another. A shipment made against the wrong sheet is not corrected at the port; it is refused, and the refusal is published where your other buyers can read it. Holding the specification against the buyer programme — thresholds, permitted treatments, the laboratory that buyer accepts — is what stops a pack-house instruction being written from the wrong memory.
Sampling and testing planned before the season, not during it
Testing has a lead time, and in a short harvest window that lead time is the whole game. When the plan for which lots get tested for what, at which lab, sits in one agronomist’s head, the tests that get done are the ones somebody remembered. Attaching the required parameters to the buyer programme and the testing task to the lot turns it into work that can be scheduled, delegated and checked before the fruit is on the water.
