Unit Price Is Not the Real Cost of Packaging

The problem is that this figure tells only part of the story.

Packaging does not generate costs only when it is purchased. It also generates costs when it takes up more storage space than expected, requires additional handling, arrives late, slows down the filling line, or results in part of the batch being rejected.

That is why comparing packaging based solely on unit price can lead to decisions that appear efficient but ultimately prove more expensive.

The real question is not how much it costs to buy a packaging component. It is how much it costs to turn that component into a finished product that is ready to sell.

The Cost Starts Before Filling

In the cosmetics and fragrance industries, packaging is part of a particularly demanding supply chain. Bottles, pumps, caps, droppers and decorative components all need to be transported, stored, handled and assembled before they fulfil their intended purpose.

Each of these stages introduces costs that rarely appear in the initial quotation.

Two bottles may have a very similar purchase price and yet perform very differently from a logistics perspective. One design may make better use of the available space inside a carton. Another may require additional dividers. One component may be shipped fully assembled, occupying considerably more volume, while another can be transported in separate parts, allowing many more units to fit on each pallet.

At that point, the difference of a few cents at purchase price begins to lose its importance.

The same applies to inventory. Ordering larger quantities may secure a more attractive unit price, but it also means more warehouse space and more capital tied up in stock. If the packaging includes a bespoke decoration, a specific finish or a custom colour reserved for a single product, another risk emerges: that inventory may lose its value before it is ever used.

In packaging, buying cheaper does not always mean buying better.

Scrap Rates Have a Cumulative Impact

There is another factor that often remains hidden behind the unit price: not every component purchased ultimately reaches the market. Rejections during incoming inspection, decoration defects, cosmetic imperfections, filling issues or assembly problems can all reduce the number of finished products.

And not all scrap has the same cost.

Detecting a defect in an empty bottle has a relatively limited impact. Finding that same defect after the bottle has already been filled, labelled, fitted with its pump and packed into its carton multiplies the associated cost.

Imagine a brand that needs 100,000 finished products. With a scrap rate of 1%, it will need to purchase just over 101,000 components. If the scrap rate rises to 5%, more than 105,000 components will be required to achieve exactly the same output.

That difference can easily outweigh the savings achieved by negotiating a lower unit price. This is why rejection rates should always form part of any meaningful comparison between packaging solutions.

What Happens on the Filling Line Also Has a Cost

A packaging component may fully comply with specifications and still perform poorly during production.

It may require manual orientation before filling. The cap may need to be positioned in a specific way. Additional inspections may be necessary, or extra handling may be required to prevent scratches. The component may even force the production line to run at a lower speed because its performance is not sufficiently consistent.

When manufacturing thousands of units, a few extra seconds per product quickly become significant. The same applies to small line stoppages, machine adjustments or rework.

For this reason, packaging costs should also be evaluated from the perspective of the filling line. The components may be technically compatible, but can they also be assembled consistently, reliably and efficiently?

Industrial compatibility has real economic value.

A Single Issue Rarely Remains a Single Issue

A micro leak, a dispenser that stops working or a cap that loosens during transport may affect only a limited number of products. Yet the impact rarely ends with the cost of replacing those individual components.

Entire batches may need to be quarantined. Hundreds of products may require manual inspection. Finished goods may need to be reworked or replaced. Purchasing, quality, logistics and customer service teams may all spend valuable time managing an issue whose real cost is rarely attributed back to the packaging itself.

And if the problem reaches distributors or end consumers, the consequences extend even further. At that point, it is no longer only an operational issue. It also becomes a question of customer confidence and brand reputation.

Consistent quality is not simply a technical requirement. It is an effective way to control costs.

Delivery Times Are Part of the Equation

In industries driven by strict commercial calendars, time has a very tangible economic value. A Christmas launch, a limited edition or a product tied to a specific release date cannot simply be postponed because a packaging component failed to arrive on time.

When packaging is delayed, the solutions are rarely inexpensive: express freight, production rescheduling, partial deliveries, last-minute changes or higher safety stocks to reduce future risks.

In this context, a supplier with a slightly higher unit price but a far more reliable supply chain may well prove to be the most cost-effective option.

Lead time, therefore, should never be considered separately from price. It is part of the total cost.

Looking at the Bigger Picture

The principle is simple, but it changes the way packaging decisions should be made.

A solution priced at €0.48 per unit may ultimately be more expensive than one priced at €0.53 if it generates more waste, requires additional handling, occupies more warehouse space or creates supply chain instability.

The comparison should not be based on the cost of purchased components, but on the cost of finished products that are ready to be sold. That requires looking at packaging as a complete system.

Design, logistics, assembly, quality and supply all interact with one another. Optimising one variable while ignoring the others often means simply shifting costs from one department to another.

At Rafesa, this is the perspective from which we approach every project. Because the most competitive packaging solution is not necessarily the one with the lowest purchase price, but the one that allows brands to manufacture, distribute and sell more efficiently, more reliably and with greater consistency.

And that difference rarely fits into a single column of an Excel spreadsheet.
