A custom box quote arrives as one number. The number is actually six costs stacked together, and two of them disappear entirely at the right order size. Buyers who understand the structure stop comparing unit prices and start comparing suppliers — which is the comparison that actually matters, because two factories quoting the same unit cost can differ by 30% in total landed cost.
This guide breaks the quote open: the six components, how the unit price curve really behaves from 100 to 10,000 pieces, why MOQ exists at all, and the five places brands consistently overspend.
The Six Cost Components
| Component | One-off or Per-Unit | Typical Range | Notes |
| Structural drawing & dieline | One-off | Included free at Qdylc; $80–300 elsewhere | Reusable across reorders |
| Cutting die | One-off | $80–300 | Only for new structures |
| Printing plates (offset) | One-off | $60–150 per color | Zero with digital print |
| Sample | One-off | $30–80 | Usually credited against production |
| Materials | Per-unit | 40–55% of unit cost | Board weight and paper drive it |
| Print & finishing | Per-unit | 20–30% | Foil, deboss, lamination extra |
| Labor & packing | Per-unit | 10–15% | Hand-assembly adds here |
Two structural facts fall out of this table immediately. First, the one-off items are fixed regardless of quantity — they’re the entire reason a 100-piece order costs more per unit than a 5,000-piece order of the identical box. Second, at Qdylc the dieline is free with every quote, which removes the biggest barrier to getting a real quote instead of a guess.
The Unit Cost Curve
Here is the same rigid box, quoted at five volumes, with the same structure and finish:
| Order Quantity | Setup Cost per Unit | Unit Production Cost | Total per Unit |
| 100 | $1.45 | $1.35 | $2.80 |
| 500 | $0.29 | $1.06 | $1.35 |
| 1,000 | $0.15 | $0.95 | $1.10 |
| 5,000 | $0.03 | $0.75 | $0.78 |
| 10,000 | $0.02 | $0.72 | $0.74 |
Read the curve correctly and three things become obvious:
- The drop from 100 to 500 is mostly arithmetic, not discount. Setup is being spread over more units. No supplier is being generous.
- The curve flattens hard after 1,000. Going from 5,000 to 10,000 saves four cents. The per-unit price stops being the interesting number.
- Between 100 and 500, the real question is cash, not cost. Paying $2.80 for 100 boxes ($280 total) to test a design beats paying $675 for 500 boxes of a design you haven’t validated.
Why MOQ Exists
Factories don’t set minimums to gatekeep small brands. Three physical constraints create them:
Machine setup time. Changing a folder-gluer or a press between jobs takes hours. A 50-piece order consumes the same setup as a 5,000-piece order — the setup has to be amortized or the factory loses money on the job.
Material minimums. Paper mills and board suppliers sell in sheets and pallets. A specialty paper often carries a 500–1,000 sheet minimum, which is why exotic materials inflate MOQ even when the box is simple.
Quality batch consistency. Color matching and finishing are calibrated per batch. Tiny batches mean more calibration runs per unit produced, and more chances for variation.
Digital printing changes the first constraint — no plates, no press setup in the traditional sense — which is how the MOQ floor drops to 100 pieces. It doesn’t change the other two, which is why 100-piece runs use stock structures and commonly available papers rather than exotic specs.
One nuance worth knowing: at some order sizes, 100 pieces is cheaper in total than 500. If the design might change after launch — and first designs usually do — $280 of validated packaging beats $675 of committed packaging. The unit price is worse and the decision is still correct.
Where Brands Overspend
Five patterns, all fixable before the dieline is cut:
- A die per SKU. Five products with five structures means five dies and five setups. Keep one internal structure and vary the printed wrap: five SKUs, one tooling cost. Saves 40–60% of setup spend.
- Full-color process print doing a two-color job. A clean two-spot-color design with a foil accent often out-performs four-color process on shelf and prints cheaper. Color discipline is a design decision with a price tag.
- Premium paper on a structure nobody sees. The customer touches the insert and the lid interior. Board upgrades on hidden panels are spend without perception.
- Air-freighting low-value packaging. Freight at 4–6× sea rates erases any unit saving on a $0.80 box. Sea freight with a reordered calendar (order 10 weeks out) is the fix — or express partial shipments for launch stock only.
- Ignoring the insert until the box is quoted. Inserts run 20–30% of total box cost and are where the customer’s hands go. Spec the insert first; the exterior follows.
How to Compare Three Quotes Properly
The unit price comparison almost everyone runs is almost useless. Run this instead:
- Demand the split. Setup plus unit, in writing. A supplier who won’t split it is hiding where their margin lives.
- Normalize the spec. Confirm all three quotes reference the same board weight (gsm), paper type, insert material, print method, and finishes. A $1.10 quote on 900gsm board is not cheaper than $1.35 on 1,200gsm.
- Check what’s included. Dieline? Sample fee? Freight? Duty? A quote excluding freight and duty isn’t a landed cost — on a DDP basis the gap between suppliers widens, not narrows.
- Ask the reorder question. “Is the reorder priced identically?” The honest answer involves the dieline staying on file and no re-charged setup for identical reorders. Suppliers who re-quote from scratch at reorder are quietly re-charging setup.
Ask those four questions and the three quotes become comparable — and the cheapest quote on paper frequently isn’t the cheapest in total.
FAQ
Why does a 100-piece order cost so much more per unit than 500? One-off setup costs — dieline, die, plates, sample — are spread across the quantity. At 100 pieces those fixed costs add $1.45 per unit; at 500 they add $0.29. The production cost itself changes far less. It’s arithmetic, not supplier generosity.
Can I order custom boxes without a 500-piece minimum? Yes, with digital printing. Because digital removes plate costs and press setup, runs from 100 pieces are viable — using stock structures and standard papers. Full custom structures with foil and specialty materials typically start at 500 pieces, where the one-off tooling amortizes reasonably.
How should I compare quotes from different packaging suppliers? Demand the setup-plus-unit split in writing, normalize every quote to the same board weight and insert spec, confirm whether freight and duty are included (landed cost, not unit cost), and ask whether identical reorders are priced without re-charged setup. The lowest unit price is frequently not the lowest total cost.
