How much does exporting crops cost?

Potential yields differ across regions, sometimes drastically. What if we just grow crops where they grow best and ship them out to the rest of the world? (This isn't practical, of course, because putting farmers out of work, especially in developing countries which tend to have lower yields, is bad.)

Here are a bunch of ocean transportation costs from the US Agricultural Marketing Service's reports:

Date Source Destination Cost
Oct24 US Gulf Japan $55
Oct24 US Pacific Northwest Japan $30
Oct24 US Gulf China $62
Aug24 Brazil China $45
Jul24 Ukraine Indonesia $55
Jul24 Ukraine China $50
May24 US Gulf Colombia $30
Apr24 US Gulf Japan $70
Dec23 US Pacific Northwest Thailand $23
Nov23 US Pacific Northwest China $30
Nov22 US Gulf Japan $80
Aug22 US Gulf China $70

So prices fluctuate but that's probably a demand issue and we can build more ships. The lower end for US to China is like $30-50 per ton. US to China is a pretty long journey, so I'd expect that to be near the higher end of ocean transportation costs.

How expensive is producing these crops and getting them to their origin ports? The International Grains Council says the cheapest staple crops are $200/ton:

  • wheat: $250/ton
  • maize: $210/ton
  • rice: $500/ton
  • barley: $200/ton

So the cost to transport crops can be 10-20% of the production cost. That's not too expensive.
