Adjustments to the tariff on corned beef are made at the beginning of the beef marketing year in April. Supplies of canned fish and canned fruit from the non-associable Commonwealth will face the first step towards the CCT on 1st January. Supplies from the developing Commonwealth which have been offered association will continue duty free. Tariff changes are not necessarily reflected in retail prices; however, it is estimated that all the tariff changes due to take place on 1st January 1974 will result in an increase of only between ¼ per cent. and ½ per cent. on the retail food price index next year.
