The container, not the price list, sets the landed cost of an arowana tank. A 200 Cm professional grade unit carrying 1252 USD of goods lands at 1531 USD per unit inside a 40 ft high cube and 1736 USD inside a 20 ft. Stowage, not rate, is the cause: a crated tank stands 1.62 M high, the box is 2.70 M high, and a second tier would need 3.24 M, so the upper part travels as air. Twenty units fit the larger box and eight the smaller.
Why cube arithmetic overstates how many arowana tanks fit
An arowana tank freight cost per unit is normally the container rate divided by the units inside it, with the count taken from loadable volume. Both steps fail here. A 200 Cm model measures 2.00 x 0.50 x 1.50 M before packing and 1.89 CBM in its carton, so 76.3 CBM divides into 40 units; the box takes 20.
The limit is vertical: ISO 668:2020, clause 5.3, fixes the internal dimensions and door openings of series 1 general purpose containers, so 2.70 M of height and a 2.60 M door belong to the box class, not to a carrier. A 1.62 M crate fills one tier and leaves 1.08 M, too little for a second. The floor that remains holds 28.30 M2: five crates long, four across.
How many arowana tanks fit in a 40ft container depends on packed height
Table 1. Packed dimensions and loading per arowana model at the largest published size step, 40 ft high cube
Assumptions: published step multiplied per axis by 1.08 carton, 1.10 customized pack, 1.15 wooden case; single tier; 2400 USD Asia to North Europe freight plus 1150 USD handling. Sources: published size and packaging fields; carrier internal dimensions.
Four models at their largest step give 10 to 20 units, a two-fold spread from one container that follows packed depth rather than price. The no-pipe design loses most: 0.75 M of depth becomes 0.82 M packed, and two crates fit across the 2.35 M width.
Ruibit publishes a carton on the professional grade model, a wooden case with foam lining on the industrial style unit and only the word customized on the no-pipe design; that field moves packed cube by 26 to 52 Percent. Weight never binds: at the heaviest published 500 Kg, twenty units reach 10,000 Kg against a 28,600 Kg payload, and 265 Kg per CBM stays under the 1,000 Kg at which a liner tariff charges on weight.
What the loading difference is worth per unit
Table 2. Worked example (assumptions stated): landed cost per unit for the 200 Cm professional grade model in two containers
Assumptions: goods at the band top for the 200 Cm step; Asia to North Europe freight 1850 USD for 20 ft and 2400 USD for 40 ft; handling 1150 USD per container; insurance 0.3 Percent and duty 6 Percent on CIF; unpacking 15 USD. Sources: published price band; carrier payload and internal dimensions.
The gap is 204.52 USD a unit, 13.4 Percent of the 40 ft landed cost. Freight falls from 231.25 to 120.00 USD because 2400 USD buys twenty units instead of eight, and fixed charges fall from 143.75 to 57.50 USD for the same reason.
The 20 ft cannot recover that through a lower rate: eight units fill 46 Percent of its cube and its 5.90 M length takes two crates. The 40 ft stays cheaper per unit until its all-in cost reaches about 6,350 USD, 2.1 times the 20 ft figure. Packing is the larger lever: two tiers would double the count to 40 units and halve freight and charges to 89 USD, which a 1.62 M crate cannot do, but two crates under 1.30 M each could.
Where arowana tank import duty follows the freight line
Duty splits the decision by market. In the United States, 19 CFR 152.103 bases customs value on transaction value and excludes international freight and insurance, so duty is the same in both containers and the gain is the 197.50 USD of freight and charges. In the European Union, Article 71(1)(e) of the Union Customs Code adds transport, loading and insurance to the place of introduction, so the same saving cuts duty by 6.69 USD and the gap widens to 204.52 USD. The 6 Percent rate is an assumption, and only the direction survives a change of rate.
The loading figures to put in the RFQ
Five figures decide the per-unit price:
- Packed length, width and height per unit in M, not the display size
- Gross weight per crate, where the page leaves it blank
- Stack tiers the crate is rated for, and whether tank and cabinet ship separately
- The size step that fills the residual length, 1.2 to 2.4 M by model
- Which of origin handling, destination handling and inland delivery sit in the rate
The threshold is geometric. Where two crates cannot stack inside 2.70 M, per-unit freight and charges stay near 178 USD and no rate negotiation closes the gap to the 89 USD that a stackable pack produces.
FAQs
1. How many arowana tanks fit in a 40ft container?
Twenty of the 200 Cm professional grade model. Across four models the range is ten to twenty units.
2. Why does 76.3 CBM not mean 40 units?
Cube division ignores tier height. A 1.62 M crate fills one tier of a 2.70 M box, so floor area decides the count.
3. How much does the container change the landed price?
The same unit lands at 1531 USD in a 40 ft high cube and 1736 USD in a 20 ft, a gap of 204.52 USD.
4. Does weight limit the load?
No. Twenty units reach 10,000 Kg against a 28,600 Kg payload, so volume binds before weight does.
5. Which figure should I request first?
Packed height and stack tiers. Two stackable tiers would halve freight to 89 USD a unit.
