Every packaging line is either something a supplier holds or something they make when you order. The choice has consequences for lead time, minimum quantity, specification and price, and it is usually made by default rather than deliberately.
What stock gives you
Speed. Days rather than weeks, which for a replenishment or an urgent replacement is often the whole requirement. Lower minimum quantities, too – you can buy a pallet rather than a production run.
What it costs is the specification. You buy what exists. If a standard size suits, that costs you nothing and stock is clearly right. If it does not, you are compromising on something that may matter.
What made-to-order gives you
The specification you actually want: the footprint that divides into your pallet, the thickness your span requires, the bore that matches your equipment, the colour that separates your flow.
What it costs is time and minimum quantity. Tooling where applicable, a production slot, and a minimum that reflects setup rather than a pallet.
How to decide
Ask whether your requirement is generic. A standard crate for a standard crop is generic – buy stock. A crate with a vent pattern for a specific pre-cooling setup is not – order it.
The second question is whether the compromise costs you anything measurable. A stock crate that gets you nine per pallet layer instead of ten costs you eleven per cent of every pallet forever. That is worth tooling for. A stock crate that is slightly the wrong shade is not.
The middle case
An existing tool, modified. A different bore, a modified handle, a different vent layout – these are edits within an existing mould rather than new tooling. They cost a fraction and take a fraction of the time, and suppliers do not always offer them unprompted. Worth asking.
Thresholds are covered in what the MOQ is for custom PP crates.
And the practical hybrid
Run stock for the urgent and unpredictable, made-to-order for the planned. Most operations end up there: a stock buffer for continuity, and periodic made-to-order runs for the items where specification is worth paying for.
How to price the compromise
Work out what the stock item costs you per year in wasted capacity rather than in unit price. A crate that fits nine to a layer instead of ten costs eleven per cent of every pallet, forever. A box that needs an extra strap costs a few seconds per pallet, forever. Both are larger than the tooling they would avoid.
Conversely, a stock item that is the wrong shade, or twenty millimetres taller than ideal, may cost nothing measurable. The test is whether the compromise shows up in a recurring cost, not whether it is noticeable.
When the answer changes
As volume grows, tooling becomes easier to justify – the same tool cost spread over more units. An item that should be stock at low volume frequently should be made-to-order at high volume, and it is worth revisiting the decision annually rather than treating it as settled.
Set a reminder. It is the kind of decision that is made once at low volume and never revisited.
What we can do
We make PP crates for fruit and vegetables in standard and made-to-order specifications and will tell you when a standard one suits. Tell us the pallet, the crop and the volume, and we will say plainly whether custom tooling is justified.
