How demurrage charges time

Demurrage is the charge for keeping a ship or a container past the time already allowed.

From the opening

Demurrage charges for time used beyond a free allowance, whether that allowance is laytime on a chartered ship or free days on a container at the terminal. The clock, not the weight of the cargo, is what the extra invoice measures. The opening covers free time ends and the clock starts, laytime is the ship's allowance, and container demurrage is inside the terminal.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
