FREIGHT, INSURANCE PROPOSED FOR CCC SALES - USDA the U.S. Agriculture Department is proposing to permit coverage of freight cost and marine and war risk insurance for sales of all agricultural commodities sold on credit terms under the Commodity Credit Corporation's, CCC, credit guarantee programs. The proposal only applies to commodities that are sold by exporters on a cost and freight, C and F, or cost, insurance and freight, CIF, basis, since these costs would be included in the exporter's sale price to the foreign buyer, it said. Under current programs, freight costs can be covered only for export sales of U.S. breeding animals. It asked for comments on the proposal by April 20.
