Before you quote — watch for
- Merged "D&D" lines hide which clock produced the charge — always demand the split before paying.
- Rail-bound boxes switch from demurrage to a rail storage tariff at the ramp — a frequent mis-billing.
- US import: the FMC rule (46 CFR 541) requires the charge to serve an incentive purpose and the invoice to carry 13 specific elements. A defective invoice eliminates the obligation to pay.
