If the shipment is based on a groupage (shared) service, we will complete a warehouse measure once returned to our depot to confirm the volume, if additional items have been added or the volume is difference from the estimated we will advise the additional costs and invoice accordingly. If you are thinking of adding additional items above the agreed volume it is wise to talk first with your move manager prior to collection day, as additional items can cause extra charges. If your service is based on an exclusive use container, then we will add space permitting, please note additional charges may be applicable as these additional items will affect the quoted rate.
