Various methods are used to obtain the data used in the Ocean Freight Rate Bulleti n. Websites such as The Pacific Shipper and The Journal of Commerce are used to determine transit times for each shipping line and trade route. Individual shipping line websites are also used. The rates, along with the surcharges, are calculated for the representative shipment. If a rate is not retrievable from either system or when a rate appears inconsistent, the shipping line is contacted directly by fax or telephone.
Rail freight is generally available through tariff and guaranteed programs.
Tariff car orders are placed directly with the rail carrier and are filled at published rail tariff rates. Generally, there are no on-time delivery guarantees by rail carriers for tariff freight orders. A venue of guaranteed rail freight programs offers shippers options to purchase freight with certain on-time delivery guarantees. This market may serve as an alternative for shippers seeking to source or divest rail freight. Data collection for each delivery month is collected for 6 months, ending on the 15th day of the delivery month.
