The contract between the customer and Arpin RI is called the Order for Service or OFS. The OFS will stipulate the loading date spread that has been agreed upon between Arpin RI and the customer. The load date spread is typically just one day, but may range from one day to several days depending on the weight of your shipment and the required extra services. Arpin of RI always tries to load the shipment on the preferred date of the customer whenever possible.
