Morphology
The meaning 'a tax based on a ship's tonnage' is directly derivable from combining 'tonnage' (the ship's carrying capacity/weight measure) with 'duty' (a tax or levy). Although somewhat technical and domain-specific, the noun+noun composition follows a transparent tax-naming pattern that a learner who knows both constituents can readily interpret.
Etymology
The term tonnage duty comes from old port taxes that were set by a ship's tonnage, or how much it can carry. Because bigger ships could carry more goods, they paid a larger 'duty', so the phrase means a tax that depends on the ship's size.
