Not your rule, but the same shape. On the credit side the invoice description must correspond with the credit, while every other document only has to not conflict with it. So the standing description gets drafted at the level a later document cannot contradict, and shipment detail stays on the shipment's invoice.
Every particular you add is one more thing that has to match. Variety, calibre, carton and label move, so I would leave them out and keep what identifies the product in the nomenclature. I have not seen a season statement fail, my discrepancies are bank side, but that is the shape it would take: the extra detail you volunteered.
Stripped that far mine reads fresh cherries, fresh table grapes, nothing else. That is the bar the text sets: identification in the nomenclature.
Where it bites is the sheet it rides on. What gets tested is the description on the document the statement is made out on, and a grape carton has to name the variety under the European marketing rules, so ours does too. The carton is the rule, the invoice is just our habit. So the season statement goes on a proforma that says nothing else.
Your silent proforma is safe, Camila: origin is the one document that can afford to be vague. The plant health certificate cannot. One per consignment, naming the variety and counting the cartons, because the identity check is matching that certificate against the pallet, not reading it.
What gets held is two documents naming different fruit. I have watched that inbound, where the shed changed variety and the certificate did not. No seasonal version of that certificate exists down here.
