The United States shipped $45.7 million worth of goods to Iran in April. That’s a tiny sum compared with the $26.2 billion the US sent to its largest trading partner, Canada, but nonetheless interesting since most forms of trade with Iran are illegal in the US. There are exceptions for humanitarian aid, though, which presumably accounts for nearly all of the goods sent to Iran.

Among the more eyebrow-raising exports: The US sent $815,536 worth of bovine semen to Iran in April, enough to sire thousands of cows. In the first four months of 2013, the US has exported more than $1.7 million dollars worth of bull sperm, down slightly from $1.8 million over the same period in 2012.

But the majority of goods exported to Iran in April were foodstuffs: 83% of the trade ($37.8 million) was in rice, lentils, chickpeas, and butter.
