How Volume Price Tiers Actually Work
Unit price steps down as quantity steps up, and the reason is not sales pressure. What drives each tier, and how to compare two quotes fairly.
A volume price tier is not a sales gesture. On an iPhone case order, the unit price steps down because fixed work is spread across more units, and the costs inside the run change shape as quantity grows. Here is what drives each tier, and how to compare two quotes fairly.

A Tier Is a Band With a Basis
A price tier is a quantity band with one unit price attached, quoted on a named material, finish, and packaging basis. Change the basis and the table describes a different product.
Retail trains buyers to read a larger pack as a promotion. A factory run does not work that way. The tier is where a supplier's fixed work gets divided, and that division is arithmetic rather than generosity. Two runs of the same case, one short and one long, are not the same production job, even though the case inside is identical.
This is why a tier table is not a price list. We do not publish a price list, because a tier means nothing until the model, the finish, and the packaging are fixed for that quote. A band copied off another supplier's sheet describes their product, not ours.
Four Costs That Move Between Tiers
Changeover comes first. A run opens with a machine setup, a color change, and a print or logo setup, and that time is spent once whether the run lasts hours or weeks. Spread across a longer run, the same setup hours sit on more units.
Material is the second cost, and it moves for a different reason. A short run draws from stock bought in mixed lots; a longer band can be planned as one material batch, and one batch carries one price and one color story. Mixing is what a small order pays for. A factory that plans its material weeks ahead can feed a larger band from one purchase instead of several.
Startup scrap sits behind the third. It exists while the machine settles and the color matches, and the reject rate tends to fall once the line is warm. That startup cost is close to fixed per run, so a long run divides it across more units while a short run carries it on fewer.
Packaging and labeling close the list, because both stay manual until the count justifies a batch routine. We print and apply labels in-house, and a larger band is what turns labeling from a bench task into a step in the schedule.
None of the four is a sales lever. Each is a real cost that behaves differently at different run lengths, which is why the unit price steps down without anyone conceding anything. The minimum order decides whether a run is possible at all; the tier question starts after that, and it asks how the cost of one run divides.
Read Every Tier on the Same Basis
Most tier tables that look wrong are being read wrong, because the bands were quoted on different bases. A figure that includes a printed logo is not the same offer as a blank case at the same band, and a band priced in a retail box is not the poly bag line beside it. Rank those numbers and you have compared packaging, not suppliers.
Read two cases side by side and the point lands. Compare a mainline design at volume with a premium build at a lower tier and the higher figure on the second tracks its build, metal buttons and armor protection, before quantity enters the picture. That is a product difference, not a tier effect.
So ask for the basis in writing next to each band: material, finish, print method, packaging, labeling, and trade term. Ask what the band counts, too. Some suppliers count pieces per model and per color; others count the total across a mixed order. The mixed-count table can look cheaper at the same band while asking you to buy more of what you did not plan.
Compare the Step, Not the Total
The table tempts you to find the lowest unit price and work backward. Read the step instead.
Take the band you can actually sell, then the next band up, and look at two things: how far the unit price falls between them, and how many extra units that step adds to your stock. The saving applies to every unit in the band, which is real money. The extra units beyond your sell-through are the ones that carry storage, cash, and markdown risk. When the step's saving on the whole band does not cover the cost of holding the surplus until it sells, the lower unit price has bought you a worse deal.
Freight belongs in the same comparison. A larger band changes the carton count and the chargeable volume, and on bulky cases the volume is what bills, so a gain on the case line can shrink by the time the container is planned. We have written separately about volumetric weight for that half of the math.
A tier table prices goods at the factory. It does not price the journey, and it does not price the stock you carry. If you want your own bands read against these four costs, our team will walk through them with you.
Common Questions From Buyers
Why Does a Short Run Cost More Per Unit?
Because the fixed work has fewer units to sit on. Setup, color matching, startup scrap, and the first labeling pass all happen once per run, and a short run divides them across a small count. The case itself may be identical to a long-run unit; the difference sits in the overhead around it.
Should I Ask for One Price or the Full Tier Table?
Ask for the full table, then read it as a set of offers rather than a menu. A full table shows where the price stops moving, and that is often the more useful fact: past that point, a larger band buys little and ties up stock. A single figure hides the shape of the whole offer.
How Do I Compare Two Suppliers' Tier Tables?
Normalize first. Match the model, the material, the finish, the print, the packaging, and the trade term, then compare band to band on the same basis. If one table counts pieces per color and the other counts the whole mixed order, restate both in the unit you actually buy. A comparison you had to build is worth more than a comparison you were handed.
What to Do Next
Start with your sell-through, not with the deepest band on the sheet. Work out how many units you can move before the next reorder cycle, then ask for the bands that sit around that number, so every tier you consider is one you could actually use.
