The union locals, the employers' association, the hiring hall they run together, and the joint committee that decides who is registered to work. Tug and barge crews belong to a separate union division.
The parties that bring a ship from the strait to the berth and out again: the pilots, the tugs, the line handlers, the ship's local agent who orders them, the Coast Guard, the traffic service it runs with Canada, and the industry body that tracks every movement.
Who owns the ground and who governs it: two county port districts, the elected commissions that run them, the alliance through which they manage the cargo business together, and the tribal government that owns land alongside.
The companies that lease each terminal, run the cranes and the gate, and sell stevedoring to the shipping lines. Four container terminals, two of them owned by the carriers they serve, plus the two Alaska and Hawaii operators.
The parties who own, book, insure and certify the cargo and the ship without handling either: cargo owners, forwarders, customs brokers, the shipping lines and their alliances, insurers, classification societies and surveyors.
The federal and state agencies with authority over some part of the work: customs and the agencies that act through it, the maritime and pilotage regulators, and the environmental agencies that permit the terminals.
What carries a container away from the terminal gate and where it ends up: two Class I railroads, the city switching line that serves the Tacoma yards, the trucks, the chassis they ride on, and the warehouses of the Kent Valley and Pierce County.
