Custom shipping containers, built to your spec at the factory.
For operators with planned demand. Doors, windows, vents, insulation, paint to any RAL code, IICL survey, branded or shipped neutral. Wholesale pricing, real lead times told before deposit, OWLU® verification at the end.
Factory production is for operators who can plan a run.
Buying from depot stock gets you containers this week. Factory production gets you exactly the containers you want — your color, your doors, your branding — across a quantity, at wholesale pricing direct from the line. The trade is time and minimum order. Real numbers on both, told before any deposit.
Adding 20 to 200 units in your fleet colors and branding. Paint goes on at the line, not in a yard.
Same door style, same vent count, same insulation R-value across every unit. Standardize the spec sheet, repeat the order.
Double doors, open sides, hard-top open tops, windows, personnel doors, insulated builds, HVAC-ready electrical. Specced at order, not retrofitted after.
IICL survey at the factory. CSC plate issued at production. ISO 6346 number under OWLU® or your prefix. Compliant out of the gate.
Standard, specialty, and modified — all factory-built.
NEW (one-trip) factory production photographed at our depots. Every standard container family (10ʹ through 45ʹ), every specialty configuration (double door, open side, open top, Duo-Con), and every modified variant we offer (side door cuts, custom hardware). Click any type for the multi-angle gallery and full ISO 6346 specs.

Every spec, told to the factory before they cut steel.
Container factories work from spec sheets. The wider the spec, the more options on the table. Here’s what we’ll spec in a typical wholesale build for an operator.
Any RAL Classic code. Single-color builds, two-tone, contrasted door panels. Paint goes on at the line — durable, factory-finished, not a yard respray.
RAL color chart →Standard cargo doors, double-door (both ends), side doors, personnel doors, lockboxes, custom hardware. Hinges, gaskets, and lock rods to spec.
Fixed or sliding. Single-glazed or double-glazed. Tempered safety glass. Positioned by spec — sidewall, front wall, in personnel doors.
Passive louvered vents, powered exhaust, condensation vents, hooded vents. Count and position to spec depending on your end use.
Wall, ceiling, and floor insulation at varying R-values. Closed-cell spray foam or rigid panel, factory-installed, with interior liner if specified.
Pre-wired outlets, LED lighting, distribution panels, GFCI circuits, HVAC-ready penetrations, mini-split A/C, generator-ready terminations.
Side-panel stencils, end-panel logos, fleet numbering, color-blocking, your BIC prefix or OWLU®. All applied at the factory.
Hardwood, bamboo, or steel floors. Plywood lining, FRP, or open steel walls. Anti-slip coatings. E-track tie-downs and dunnage strips.
ISO 6346 plate with owner prefix and check digit. CSC Safety Approval plate. IICL pre-shipment survey at the factory. Compliant from day one.
From spec sheet to your depot, in five stages.
- 01Send your spec sheet
Quantity, size, type, customization list. If you don’t have a spec sheet template, we provide one — operator-grade, no fluff. Phone or email works.
- 02Factory match
We map your spec to a factory partner who can build it — capacity, lead time, MOQ, surveyor. Different specs run on different lines. We tell you which line, why, and what trade-offs exist.
- 03Production schedule confirmed at deposit
Wholesale pricing, lead time in weeks, MOQ for your spec, container number range, surveyor and CSC vendor — all in writing before deposit. No surprises after the wire clears.
- 04Production milestones
Steel cut, panels assembled, paint applied, doors fitted, interior finished, plates installed, IICL surveyed. Status updates at each milestone if you want them.
- 05Shipment to your depot or direct
Loaded for ocean transit, vessel booked, U.S. port arrival, depot drop or direct delivery to your site. Documents, container numbers, BIC verification, CSC plate — all handed off at release.
What we tell you, in writing, before any money moves.
Factory production has more variables than depot stock. We commit to surfacing every one of them up-front. If something changes mid-build (rare, but it happens), you hear about it before you hear about it from the depot.
For the exact spec, exact quantity, exact factory.
Production + ocean transit + depot or site delivery.
Some custom builds require minimums. We tell you the floor.
The block of OWLU® or your-prefix numbers we’ll assign.
We hire Unicon BV to inspect the production process at the factory and sign off on technical acceptance and quality control before the unit ships.
Steel-cut date, paint date, survey date, ship date. Real calendar.
Three branding paths.
BIC code is the four-letter owner prefix stenciled on every container. It’s issued by the Bureau International des Containers in Paris. For a factory build, you have three branding choices.
Your build ships under our BIC prefix. Verifiable in the public registry, covered by our federally registered trademark. Fast — no BIC application wait.
You hold (or will register) your own BIC code. We coordinate with the factory to stencil your prefix at the line. Requires your BIC application cleared in advance.
No prefix at the factory — you apply branding after the fact. Faster build, fewer compliance hurdles, but requires post-build paint or vinyl. Best for short-haul or domestic-only use.
What operators ask before a factory build.
What’s the minimum order quantity?
It depends on the spec. Standard 20ʹ and 40ʹ GP units in stock colors run lower minimums. Custom paint, double doors, insulated builds, and side-door configurations have higher minimums because they require dedicated production slots. We tell you the floor for your exact spec before you deposit.
How long is the lead time?
Factory production is measured in weeks, not days — and varies by factory backlog, ocean transit windows from Asia, and U.S. port congestion. We give you a real lead time in writing before you deposit. If a factory slot opens up sooner, we’ll tell you. Current factory and depot conditions are on the lead times page.
Can I see a sample before ordering?
For paint colors, the RAL Classic chart is the standard reference — every container factory paints to RAL. For door/window/vent configurations, we can send factory specs and photos from prior similar builds. For unusual specs, a sample unit is sometimes possible at additional cost.
Do you handle import paperwork and customs?
Yes for builds shipping under OWLU® — we are the importer of record and handle entry, duties, and depot delivery. For builds under your own BIC prefix where you act as importer, we coordinate with your customs broker but the entry is yours.
What’s the warranty?
Factory builds come with the factory’s structural warranty — typically against manufacturing defects in steel, welds, paint adhesion, and floor lamination. Terms vary by factory and we surface them with the production schedule. Survey grade (IICL) is a separate guarantee of condition at handoff.
Can I cancel after deposit?
Once steel is cut to your spec, cancellation costs are real and we’ll surface them in writing. Before steel-cut, deposit may be partially recoverable depending on factory milestone. We don’t take deposits we haven’t earned the right to keep.
A spec sheet starts a conversation.
Custom builds have variables that don’t fit a form — factory selection, lead time vs MOQ trade-offs, branding compliance, surveyor selection. We’ll work through them in one conversation. Email works for the same thing — same inbox, same response time — just slower.
Or email sales@onewaylease.com with your spec — we answer same business day.
Real numbers before any deposit.
