Typical grain transshipment rates in Ukrainian ports: $8–15/t depending on terminal and volume. Survey (independent weighing/quality) ~$0.5–1/t. Vessel demurrage — $5,000–20,000/day! Underloading a barge = deadfreight — you pay for empty space. 'Port-stevedore-customs' splits are calculated separately at each terminal.
