The freight bill alone says ocean always beats rail to Europe: roughly $72/cbm against $148/cbm at current levels. But cargo sitting on a vessel for 35 days is working capital you've paid for and can't sell. Add inventory carrying cost and the answer flips for a large class of goods.
Take carrying cost at 20% of cargo value per year — capital cost plus obsolescence risk, conservative for consumer electronics. A cbm of goods worth $5,000 costs about $2.70 per day in transit. Ocean's 16-day transit advantage over rail therefore costs roughly $43/cbm in carried inventory — against a rail premium of $76/cbm. Ocean still wins, narrowly.
Now double the cargo density of value: at $10,000/cbm, the 16 extra ocean days cost $86/cbm — more than the rail premium. The crossover at current rates sits near $9,000/cbm, which for typical packing densities is around $14/kg of product value.
Garments, furniture and commodity goods: ocean, always. Smartphones, network equipment, premium small appliances: rail deserves a line in every quote comparison — which is why our rate console shows it automatically for European destinations. And for genuine launches and stockouts where days equal lost revenue rather than carrying cost, air remains its own category.
