Terminal 18 (Seattle)
SSA Terminals · Seattle / Tacoma · USSEA
The Northwest Seaport Alliance publishes terminal free time separately from the carrier tariff, and rail-bound boxes switch from demurrage to a rail storage tariff at the ramp — a frequent mis-billing.
Which clock is whose
NWSA terminals publish free time separately from the carrier tariff, so the terminal clock and the carrier clock rarely expire on the same day.

What is usually reversible
Rail-bound boxes move from demurrage to a rail storage tariff at the ramp — one of the most common mis-billings in the Pacific Northwest. US import: under the FMC rule (46 CFR 541) a demurrage or detention invoice must carry specified information and the charge must serve a genuine incentive purpose. A defective invoice eliminates the obligation to pay.
