The box is priced by volume, not by weight
Most buyers treat packaging as a marketing item that gets settled after the product is finished. It is not. It is the single variable that decides how much air you ship, and on consumer electronics air is usually what you are paying for.
Freight is billed on chargeable weight: the greater of the actual weight and the volumetric weight. A light product in a slightly oversized carton is billed as if it weighed several times more. A switch that weighs 200 grams in a box that is 4 centimetres too tall across a pallet can cost more to move than the difference between two suppliers' unit prices.
This is why the packaging drawing belongs in the cost conversation, not in the artwork conversation. A two-centimetre reduction on one dimension, multiplied across a container, is a real number, and it is a number that repeats on every reorder for the life of the product.
Custom packaging has its own minimum, and it fights your first order
On our ladder, custom packaging starts at 500–1,000 pieces. Standard models start at 500 pieces per colour. Those two numbers are the same order of magnitude, which is the problem: on a first order the packaging minimum and the product minimum arrive together, and if you are testing the market with 500 units you are committing to a full print run before you know whether the product sells.
There is a cheaper path and it is not a compromise. Plain white box plus a printed label or a sleeve gives you branded retail presence with a fraction of the minimum and a fraction of the lead time. You move to a printed carton at the second or third order, when the volume justifies the run and the artwork has stopped changing.
The buyers who insist on a full colour carton at 500 pieces usually discover two things: the unit cost of the box is high at that quantity, and the artwork is wrong by the time the second order arrives.
Lead time lives in the box too
Sampling runs 7–15 days and tooling 25–40 days, and those numbers describe the product. The packaging has its own clock: artwork approval, plate or plate-less digital setup, print run, and then assembly. A print house will not start without approved artwork, and artwork revisions are the most common cause of a shipment slipping after the product itself is ready.
Practically this means packaging artwork should be locked while the product is still in sampling — not after the confirmation sample is approved. Doing it in parallel removes a week or two that otherwise lands at the worst possible moment.
Three things that fail on the packing line
Packaging failures are almost never aesthetic. They are mechanical. The carton closes in the design file and does not close on the line because the cable bundle is thicker than the drawing assumed. The insert holds the product in the render and lets it shift in the drop test. And the master carton quantity does not divide the pallet, so the last layer is half full and ships badly.
None of these show up in a photograph of a nice box. All of them show up in a damage rate three months after launch.
What packaging actually has to do
Four jobs, in order: survive the drop and vibration test for the channel it sells through, hold the product and its accessories without movement, present the brand at shelf or in the listing photograph, and carry the compliance markings the destination market requires.
That last one is the one people forget. Country of origin, disposal symbol, importer address, rating labels, and in some markets a local-language requirement. The markings have to be on the box, and they have to be correct for each destination, which is another reason to keep the first run simple: a label is easy to change per market, a printed carton is not.
Where this sits against the other cost lines
Packaging is one of four costs that quietly decide landed cost, together with the tooling amortisation, the certification file, and the freight mode. Buyers optimise the unit price and then discover the box, the mould, the file and the air freight. None of those are hidden — they are just decided in different documents by different people.
Settling packaging early, in the same conversation as MOQ and lead time, is the cheapest way to avoid a container of product arriving with a carton that costs more to ship than it did to print.
