Why Does Haiti Import Cement When Haiti Is Rich In Limestone?

If there is any cement tagged as 'made in Haiti', the clinker (the nodule produced by sintering limestone and clay during the cement kiln stage) is actually imported to Haiti to make the final product. In other words, the limestone in Haiti is not being used at all to manufacture cement.
