Publisher must provide the capability to search for tariff matter by non-case sensitive text search. Text search matches for commodity descriptions must result in a commodity or retrievable commodity index list.(c)Commodities and TRIs. Retriever selection of a specific commodity from a commodity index list must display the commodity description and provide an option for searching for a rate (e.g., on the basis of origin/destination) or a TRI list, if multiple TRIs are in effect for the commodity.(d)Object groups. Retriever selection of a specific object group must result in a list of the objects within the group or present a text search mechanism to allow location of an object within the group. For example, selection of the rules object group would present a list of the rules or a text search mechanism for locating specific terms or phrases within the rules.(e)Basic ocean freight. The minimum rate display for tariffs must consist of the basic ocean freight rate and a list of all assessorial charges and surcharges that apply for the retriever-entered shipment parameters. The tariff must indicate when other rules or charges apply to a shipment under certain circumstances.(f)Displays.
