How many office desks fit in one 20ft or 40HQ container? Almost every purchase plan starts with this question: before choosing a model, importers and contractors need to know how many units travel per sailing, because that number decides the landed cost per desk. Get the cube wrong and you pay freight for empty air.
This guide by the BG Office Furniture team in Foshan — an office furniture manufacturer supplying importers, distributors and project contractors across Southeast Asia, Central Asia, the Middle East, Africa and Latin America — covers practical CBM capacity, expected loads per product type, and how to build an efficient mixed container.
Why Container Capacity Decides Your Unit Cost
EXW or FOB is only part of the total cost. Ocean freight, terminal handling, trucking and duty are charged per container, not per unit. The only lever on cost per desk is filling the box.
- Freight is billed per container. A container loaded to 70% pays 100% of the sailing rate.
- Fill ratio matters most. Moving from 60% to 88% utilisation can cut the logistics component per unit by almost a third.
- 85–90% is a healthy target. Below that there is usually room for chairs, cabinets or partitions.
Container Basics: CBM, Payload and Real Limits
| Container | Internal volume | Practical load | Payload |
|---|---|---|---|
| 20ft (20GP) | ±33 CBM | 26–29 CBM | ±28,000 kg |
| 40ft (40GP) | ±67 CBM | 55–60 CBM | ±26,700 kg |
| 40ft High Cube (40HQ) | ±76 CBM | 64–68 CBM | ±26,400 kg |
Office furniture is volumetric cargo: CBM, not weight, is the constraint. A 40HQ packed with 130 knock-down executive desks weighs roughly 8–10 tonnes — far below payload. Space, not tonnage, is the asset you must sell out.
Calculating CBM per unit
Multiply length × width × height in metres for every carton, then add the cartons of one unit. A knock-down 1800 mm executive desk typically ships as three cartons: top 1.85 × 0.95 × 0.18 m (0.316 CBM), panels 1.25 × 0.70 × 0.14 m (0.123 CBM) and frame 1.10 × 0.45 × 0.14 m (0.069 CBM) — about 0.51 CBM per unit, or roughly 53 units in a 20ft and 129 units in a 40HQ.
Expected Loads by Product Type
| Product | CBM/unit (KD) | 20ft | 40HQ |
|---|---|---|---|
| Staff desk 1200 × 600 | 0.18–0.22 | 120–145 | 300–345 |
| Executive desk 1800 | 0.45–0.55 | 48–60 | 120–140 |
| L-shape director desk 2000 | 0.60–0.75 | 36–45 | 88–105 |
| 4-person bench workstation 2400 | 0.60–0.80 | 34–44 | 82–105 |
| Meeting table 2400 × 1100 | 0.25–0.32 | 85–105 | 200–255 |
| 4-door filing cabinet | 0.30–0.40 | 68–90 | 165–210 |
| High cabinet 2000 | 0.35–0.45 | 60–78 | 145–180 |
| Office chair (1 carton) | 0.15–0.20 | 135–175 | 330–400 |
Expect ±10–15% variation depending on board thickness, accessories and stacking.
What Changes the Number of Units
- Knock-down vs assembled: flat-packing saves 40–60% of volume, which is why almost all export office furniture ships KD.
- Board thickness: upgrading tops from 18 mm to 25 mm increases carton volume although unit counts rarely change much.
- Protective packing: foam, corner protectors and extra wrapping for long sea routes add 5–10%.
- Pallets: a standard pallet consumes 0.9–1.2 CBM; KD shipments normally skip them.
How to Maximise Container Fill
- Mix big and small items so chairs and partitions fill the gaps above desks and cabinets.
- Request a loading plan before production so the factory sequences production and carton sizes accordingly.
- Lock freight early: above roughly 15 CBM, FCL normally beats LCL per unit.
- Use preference tariffs: Form E under ACFTA brings duty to 0% on Chinese furniture into ASEAN markets.
- Standardise sizes (1200/1400/1600/1800 mm) to avoid design changes that inflate carton dimensions.
FAQ: Container Load and Office Furniture Imports
How many desks fit in a 20ft container?
As a rule of thumb, a 20ft container (26–29 CBM practical) holds about 50–55 knock-down 1800 mm executive desks, 120–145 staff desks 1200 mm, or around 40 bench workstations.
Is one 40HQ cheaper than two 20ft containers?
Almost always. A 40HQ offers about 2.3 times the volume of a 20ft while paying freight, port charges and paperwork once; on many routes the rate is only 25–40% higher, halving the cost per CBM.
Can one container hold several products and finishes?
Yes — that is how most distributors buy. A mixed container combines desks, workstations, cabinets and chairs in one shipment under one Form E.
Conclusion
Container capacity is a commercial decision, not just logistics. Calculate CBM per unit, compare it against 27 CBM (20ft) or 66 CBM (40HQ) of practical space, then build a mix that fills 85–90%. Accurate cube figures keep your landed cost per desk predictable from day one.
