Port free days refers to the number of days for which a port allows the importer to keep the containers in the port area for free. once the limit of port free days is exceeded, the port storage charges published in the port tariff are applied.
On the other hand, line-free days is the number of days the shipping line gives to the customer to pick up a full container, take it to their facility for unpacking and return the empty container to the concerned shipping line. After the line free days, the shipping line imposes a charge for every extra day taken by the customer to return the container.
