Demurrage charges are applied to the consignee by the shipping line when a container stays in the port for longer than a set period of time. The period of time is determined by the shipping line, which varies between 5 to 7 days. This is a standard procedure at all ports across the UK.
A reason why the container might be held at the port is if it has been held to be checked by customs. The charges are applied daily, at a rate of £40 to £60 per day. In order to avoid demurrage charges on businesses in the North Cornwall constituency, the Government is minimising delays and ensuring a smooth running of the border port.
