The Port of Portland just can’t catch a break. If it’s not a dispute between unions or a grain-terminal lockout, then it’s an ugly kernel of genetically modified wheat prompting countries to halt all exports.

And year-to-date through April, every unit and tonnage is down double digits — containers, grain, autos, break bulk — except one. Mineral bulk grew 20%.
