Food OEM shelf life: work back from the buyer’s receiving date
A product can leave the factory within its stated life and still arrive with too little time to sell. Specify the remaining life at each handover, then ask what product and route evidence supports the proposal.
“Six months” does not define the receiving condition
A buyer orders a private-label sauce for overseas retail and asks for “six months shelf life”. The manufacturer may understand that as the total period from manufacture. The retailer may mean six months remaining when the goods enter its warehouse. Those are different commitments.
Write down the event that starts the stated life, the date marking used, the point at which the remaining period is measured and who checks it. Include factory holding, dispatch, transit, clearance, receiving and onward distribution. Identify the proposed storage conditions at each step; a transport estimate alone does not describe the product’s exposure.
Spend time on the route before promising time to sell
This fictional example starts with a product-specific, already supported 180-day life from manufacture. There are 10 days of factory holding, 35 days of transport and clearance, then 5 days before the buyer receives it: 50 days used, 130 days remaining. A receiving requirement of 120 days leaves only 10 days of scheduling margin.
The example checks calendar feasibility only. It does not establish that any sauce has a 180-day life, that these route times are reliable or that delays and temperature excursions are acceptable. Use actual dates and the applicable counting convention for the order.
- 1Manufacture → dispatch: 10 days
- 2Transport, clearance and receiving: 40 days
- 3Receipt: 130 days remain; buyer asks for 120
Illustrative only: 10 + 40 + 130 = 180 days. The 10-day margin at receipt is inside the 130 days, not an additional validated life.
Ask for the basis of the life, separately from the schedule
Food Standards Scotland’s public summary stresses evidence suited to the food and its foreseeable distribution, storage and use; it gives no single method for all products.[1] The FSA product-description guidance also brings the food, pack and handling conditions together.[2]
Ask which formulation, process, pack configuration and storage conditions the supporting work covers, and whether the proposed export route is within that scope. A trial for a different bread or a different pack cannot simply be attached to this sauce as its shelf-life evidence. Have the responsible food specialists identify gaps, suitable evaluation and acceptance criteria.
If the buyer asks for more time than the supported product and route can provide, discuss a different schedule or a product/pack development proposal for assessment. Do not solve the gap by printing a later end date. Date marking and market requirements need review for the actual destination.
Use one receiving-condition sheet for comparable quotations
Keep requirements, supplier proposals and unresolved points in separate fields. Agree who accepts the incoming lot and what happens when the remaining period or handling record does not meet the agreed condition.
| Record | Buyer specifies | Supplier substantiates or flags |
|---|---|---|
| Product and pack | Buyer specifiesRecipe reference, pack size, closure and destination | Supplier substantiates or flagsExact version and any proposed change |
| Total life | Buyer specifiesRequired period and start event, subject to assessment | Supplier substantiates or flagsSupported period, conditions and evidence scope |
| Dispatch and receipt | Buyer specifiesHandover points and minimum remaining life | Supplier substantiates or flagsPlanned manufacture/dispatch dates and feasibility |
| Route conditions | Buyer specifiesHandling, storage, route and known delays | Supplier substantiates or flagsAssumptions, records and unevaluated exposure |
| Delay or deviation | Buyer specifiesContact, hold and disposition decision owner | Supplier substantiates or flagsNotification and records needed for assessment |
Recheck the sheet when a route or pack changes
A new warehouse, longer consolidation or a revised closure may change the question the earlier evidence answered. Keep the changed condition visible rather than treating an unchanged product name as proof that all earlier work still applies.
For the first enquiry, send the product and pack reference, destination, intended handling, likely route time and minimum life required at the named receiving point. Unknown route details can stay open, with a person and date for resolving them.
