Although CARIFTA itself was limited to trade in goods, it freed approximately 90% of intra-regional trade in manufactured goods and instituted managed intra-regional trade in some agricultural products. Between 1968 and 1973 the absolute trade, diversity of traded goods and the significance of intra-CARIFTA trade relative to external markets all increased notably. Intra-CARIFTA imports rose from EC$95 million in 1968 to EC$300 million in 1973. Whilst foodstuff and petroleum products accounted for the bulk of this trade, a range of new manufactured items (particularly from Jamaica and Trinidad & Tobago) began to be supplied for the first time. Diversification not only occurred in the types of goods sold but in the matrix of trade relationships with Jamaica's trade expanding away from the traditional markets of Belize and the northern Caribbean towards the southern and eastern Caribbean while Trinidad & Tobago's trade concurrently expanded from the traditional markets of Guyana and the Eastern Caribbean towards Jamaica, Belize and the northern Caribbean. Additionally the LDCs, particularly Saint Lucia, Dominica and St. Vincent & the Grenadines benefitted from increase exports to the More Developed Countries (MDCs - Barbados, Guyana, Jamaica, and Trinidad & Tobago) of ground provisions (like sweet potatoes), copra and raw oils (such as coconut oil) under the Agricultural Marketing Protocol and the Oil and Fats Agreement (which was initially an Agreement among some regional states that pre-dated CARIFTA but was incorporated into CARIFTA as a Protocol and extended to all CARIFTA members in 1970) respectively.
