If you’re pricing out custom shipping boxes for the first time, the range you’ll see quoted online — anywhere from $0.40 to $6 a box — probably looks less like a price list and more like a shrug. That range is real, but it’s driven by a handful of specific variables: board strength, print coverage, and how many units you order at once. Once you know what’s pushing the number up or down, getting an accurate quote takes minutes instead of days.
This guide walks through what custom shipping boxes actually cost at different volumes in 2026, how minimum order quantities and lead times compare across suppliers, and how to pick a board strength that won’t fail in transit. The goal is to get you to a purchase order with the right spec the first time, rather than a reorder six weeks later.

What custom shipping boxes actually cost
Custom shipping boxes are priced per unit, and that unit price moves based on three levers: board type, print coverage, and quantity. A plain kraft mailer with a one-color logo at low volume sits toward the bottom of the range; a full-color, double-wall box ordered in a few hundred units sits toward the top. Simple corrugated mailers with minimal print run roughly $0.40-$1.20 per unit at small volumes, while printed folding cartons ordered 1,000-3,000 at a time land closer to $1.00-$3.00 each.
Quantity is the single biggest lever. Per-unit cost falls sharply between 250 and 5,000 pieces, then levels off — moving an order from 500 units to 5,000 can cut the price per box by 30-50%. That’s because tooling, plate setup, and press changeover costs get spread across more boxes; the marginal cost of board and ink barely changes. If you’re placing a repeat order, ask your supplier where their next price break sits before you finalize a quantity — rounding up to the next tier is often cheaper than ordering exactly what you need.
Custom shipping boxes cost more than generic stock cartons mainly because of print setup, not the board itself. If your run is small and margin is tight, ask about a stock-size box with a printed shipping label or a single-color hit instead of full custom tooling — it captures most of the branding value at a fraction of the plate cost.
Board strength: single wall vs. double wall
Board strength is rated two ways: Edge Crush Test (ECT), which measures stacking strength, and the older Mullen burst test, which measures puncture resistance. Both show up on box specs, and suppliers increasingly quote ECT alone since it correlates better with how boxes actually perform on a pallet.
| Board Type | ECT Rating | Mullen Burst Rating | Max Weight Capacity |
|---|---|---|---|
| Single wall (standard) | 32 ECT | 200# | 65 lbs |
| Single wall (heavy-duty) | 44 ECT | — | 95 lbs |
| Double wall (entry-level) | 48 ECT | 275# | 100 lbs |
Single wall for standard shipments
32 ECT (equivalent to 200# Mullen) is the workhorse spec for e-commerce shipping — it’s what most suppliers ship by default unless you request otherwise. It handles boxed goods up to about 65 lbs and is the cheapest board to source, since it’s the highest-volume grade mills produce. If your product is under 20 lbs and not fragile, there’s rarely a reason to pay more.
Double wall for heavy or fragile loads
Once you’re shipping dense product — books, tile samples, machined parts, multi-item bundles over roughly 40 lbs — single wall starts to show flex and corner crush in transit. Double-wall board, starting at 48 ECT and a 275# Mullen rating, holds up to 100 lbs and resists the puncture and crush damage that drives return-to-sender claims. It costs more per square foot and adds slight bulk to the finished box, so it’s worth reserving for SKUs that actually need it rather than specifying it across your whole line.
Minimum order quantities and lead times
Minimum order quantities have come down over the past few years as digital printing has made short runs viable. Several suppliers now accept orders as low as 50-100 units, though a handful still require samples-only minimums of 1-10 pieces if you just want to test fit and print quality before committing. True wholesale pricing — where the per-unit cost stops dropping meaningfully — usually kicks in around 2,500-5,000 units.
On timing, budget 7-10 business days for standard production after you approve a proof, plus 2-5 business days for ground shipping, so 2-3 weeks door to door is a realistic baseline. Rush production, when offered, can compress that to 4-6 business days but usually carries a surcharge and may exclude specialty finishes like foil stamping or soft-touch lamination, which each add 2-3 days on their own. First-time orders also need to account for proof turnaround — expect 1-5 additional days for artwork review before production even starts, longer if your die line needs structural changes.
| Supplier | Minimum Order | Starting Price | Standard Lead Time |
|---|---|---|---|
| Teal Packaging | 50 units | $0.44/unit | ~7 business days |
| EcoEnclose | 100 units | Quote-based | Quote-based |
| Box Genie | 100 units | Quote-based | Quote-based |
| Plus Printers | 100 units | Quote-based | 12–15 business days |
| Packlane (mailers) | 1–10 units | Quote-based | 7–10 business days |
Flute type and print method
Flute profile affects both strength and how crisp your print looks. C flute is the default for shipping cartons — about 5/32 inch thick, giving a practical balance of cushioning, stacking strength, and material cost. B flute is thinner and prints more cleanly, which is why it shows up more on retail-facing folding cartons than transit boxes. E flute is thinner still and best suited to small, light items where shelf presentation matters more than drop resistance.
Flexo vs. digital printing
Flexographic printing uses physical plates and is the cheaper option once you’re past a few hundred units — plate cost is fixed, so it amortizes down as volume climbs. Digital printing skips the plate entirely, which makes it the better choice under roughly 500 units or when you need multiple SKU variants (seasonal designs, regional language changes) without paying for new tooling each time. Color accuracy on digital has closed most of the gap with flexo in the last few years, though very large solid color fields still print more evenly off a flexo plate.
What print coverage adds to the price
A single-color logo hit on kraft board is the cheapest option and barely moves the per-unit price. Full bleed, multi-color graphics increase cost noticeably because they require more plates (flexo) or more pass time (digital), and they narrow your board options — some recycled or heavily speckled kraft stocks don’t hold fine detail or bright white backgrounds well.
Before you submit a purchase order
Get a physical sample before committing to a full production run, even if it costs a small sample fee — screen renderings of box color and print saturation are consistently off from the finished product. Confirm the interior dimensions, not just the outer footprint, since wall thickness on double-wall board eats more interior space than single wall at the same outer size. Ask your supplier directly what their price break points are; many won’t volunteer that ordering 10% more hits the next pricing tier and actually lowers your total cost.
Finally, check what’s included in the quoted lead time. Some suppliers quote production time only and treat freight as a separate line; others give you a door-to-door estimate. Get it in writing if you’re working against a launch date or a retailer’s inbound deadline.
Frequently asked questions
What’s the minimum order quantity for custom shipping boxes?
Most suppliers set minimums between 50 and 100 units for short-run digital printing, with true wholesale pricing starting around 2,500-5,000 units. A few suppliers accept sample orders as small as 1-10 units so you can test the box before a full production run.
How long does it take to get custom shipping boxes made?
Standard production runs 7-10 business days after you approve a proof, plus 2-5 business days for shipping — roughly 2-3 weeks door to door. Rush options can shorten production to 4-6 business days but often add a fee and may exclude specialty finishes.
Should I choose single wall or double wall board?
Single wall at 32 ECT (200# Mullen) handles most e-commerce shipments up to about 65 lbs and is the cheapest option. Double wall, starting at 48 ECT and 275# Mullen, holds up to 100 lbs and is worth the extra cost for dense, heavy, or fragile products where crush and puncture damage are a real risk.
Do custom shipping boxes cost more than plain stock boxes?
Yes, mainly because of print setup rather than the board itself — plate costs (flexo) or artwork setup (digital) add a fixed cost that stock boxes don’t carry. That gap shrinks a lot at higher volumes, since setup costs spread across more units.
What’s the difference between ECT and Mullen ratings?
ECT (Edge Crush Test) measures how much stacking pressure the board can take before crushing, which correlates closely with real-world pallet performance. Mullen measures burst/puncture resistance. Most suppliers now quote ECT as the primary spec, though both numbers often appear together on a box certificate stamp.
The bottom line
The fastest way to get an accurate quote on custom shipping boxes is to walk in with three numbers already decided: your target weight capacity, your realistic order quantity, and your deadline. Those three inputs determine board strength, price tier, and whether standard or rush production fits your timeline — everything else is a variation on those choices. Request a physical sample before your production run, confirm what’s actually included in the quoted lead time, and ask about the next pricing break before you finalize a quantity.
