Imports, which were very low until the 1980s, increased until the end of the following decade, but subsequently tended to gradually decline. Exports show growth from the beginning of the century with subsequent stabilization. The relationship between production and apparent consumption from 2010 onwards shows a surplus production of kaolin, suggesting that part of the exploited kaolin is not being sold. The problem is not due to an over-exploitation of resources, but probably to the need for a more selective exploitation with an impact on the quality of the kaolin and the full use of the exploited raw materials. Given the current sociopolitical situation, an increase in national exports of kaolin is expected.porKaolinProductionImportExportApparent consumptionCaulinoProduçãoImportaçãoExportaçãoConsumo aparenteconference object
