The honest answer first: no serious manufacturer can quote you a real price from a search result, because the unit price is only one of six cost blocks in a container house project. The total landed cost of buying container houses from China = factory unit price (FOB) + ocean freight + customs clearance and duties at destination + inland transport + foundation works + on-site installation. Anyone who quotes you a single number without knowing your specification, quantity, and destination port is guessing. This guide breaks down each cost block, explains why quotations between suppliers can differ by 2–3 times for a similar-looking unit, and shows you how to compare quotes on an equal basis.
Use this table to map who controls each cost block and when it should be confirmed:
| Cost Block | What It Covers | Who Confirms It |
|---|---|---|
| 1. Factory unit price (FOB) | The house itself: steel frame, wall and roof panels, floor, doors, windows, electrical | The manufacturer, based on your written specification |
| 2. Ocean freight | Container booking from the Chinese port to your destination port | Freight forwarder; rates change weekly |
| 3. Customs, duties, clearance | Import duties, taxes, documentation at destination | Your licensed customs broker — rates vary by country and change often |
| 4. Inland transport | Port to site, including any oversize handling | Local transport contractor |
| 5. Foundation | Concrete piers, pads, or ground beams depending on soil and site | Your local civil contractor, per manufacturer's foundation drawing |
| 6. Installation | Local labour and tools for assembly on site | Your crew, guided by the manufacturer's installation manual or video |
Why this matters: for multi-unit camp projects, blocks 2–6 frequently add a substantial share to the total project cost, and they scale differently than the unit price. A cheaper unit that wastes container space can cost you more per installed unit than a better-packed one.
When one supplier quotes twice as much as another for a unit with the same footprint, the difference is almost always inside the specification — not in anyone's profit margin. Before comparing any two quotations, put these items in writing:
| Specification Item | What Moves the Price | What to Ask For |
|---|---|---|
| Steel frame | Steel thickness and galvanisation quality drive both cost and structural life | Steel thickness (mm) of columns and frame in writing |
| Wall and roof panels | Core material, thickness, and fire rating differ hugely between suppliers | Panel thickness, core material, and fire class with test documentation |
| Floor | Board type, thickness, and surface layer affect load capacity and durability | Floor build-up in writing (board type + surface) |
| Doors and windows | Frame material, glazing, and lock quality vary widely | Brand level or material grade specified, not just "included" |
| Electrical system | Breaker count, socket positions, cable standard, certifications for your market | Electrical layout drawing matched to your local voltage and plug standard |
| Layout and windows-to-wall ratio | More openings = more material cost and more factory labour | Number and position of doors/windows confirmed on a drawing |
A supplier who answers all six items in writing is a manufacturer who knows its own product. A supplier who replies "don't worry, good quality" has answered your question.
Ocean freight is quoted per container, not per house. So the number of houses you fit into one container directly divides your freight cost per unit — and this is where flat-pack and foldable engineering pays for itself:

When you compare two quotations, ask both suppliers the same question: "How many units of this model fit in one 40HQ, and what is your packing plan?" The answer converts a freight quote into a freight cost per house — which is the number that actually hits your budget.
These are the baseline terms Wanbang works to on export orders — use them as a reference point when comparing suppliers:
| Term | Baseline |
|---|---|
| Minimum order | From 1 set — sample orders accepted |
| Payment terms | 50% deposit, 50% balance before shipment |
| Production lead time | Typically 10–15 days for standard flat-pack and expandable units after deposit |
| Shipping port | Nansha, Guangzhou (South China) |
| Documentation | Commercial invoice, packing list, bill of lading, certificate of origin; product test documents on request |
Two honest caveats. First, customs classification, duty rates, and local building approvals vary by destination country and change frequently — confirm them with your licensed customs broker or local certifier; a manufacturer can supply product documentation and test data, but should not be your source for duty rates. Second, lead time depends on order volume and production schedule; your project timeline should be confirmed against the factory's current schedule at order stage, not assumed from any website.
Send the manufacturer this information and you will get a number that survives contact with reality:
A manufacturer that replies to this list with a specification sheet, a layout drawing, and a packing plan — not just a price — is the one to shortlist. For how to vet that manufacturer further, our factory-selection checklist covers the eight checks to run before any deposit.

Because the unit price depends on specification, quantity, and destination. A published number would either mislead buyers or be so padded it is useless. Serious factories quote against a written specification, usually within a few working days.
For flat-pack models that ship knocked down, 14 sets per 40HQ is a realistic benchmark. Foldable models typically achieve 10 sets per 40HQ with 50 mm wall panels, or 8 sets with 75 mm panels. Fixed-width expandable units take one shipping slot per unit but expand into a full layout on site.
No. The number that matters is the landed, installed cost per unit: unit price + freight per unit (driven by packing efficiency) + duties + inland transport + foundation + installation. A better-packed unit at a slightly higher FOB price frequently wins on total cost.
Wanbang accepts orders from 1 set, so you can validate quality with a sample before committing to a camp-scale quantity. Unit pricing improves with volume.
Production of standard flat-pack and expandable units typically takes 10–15 days after deposit. Ocean freight and customs timelines depend on your destination and are confirmed by your freight forwarder — plan the site date backwards from installation day, and place the deposit at least a production cycle ahead of it.
