I'm not sure how this would benefit Iceland. Just about everything needs to be imported.
If the Grapvevine is to be believed, they're importing ice cubes!

But most of Grapevines content belongs to this cute or fun news category. In this instance, they source the government radio (RÚV)[http://www.ruv.is/frett/flytja-inn-klaka-i-tonnavis], which is definitely a trusted source.
So yes, apparently we do import ice-cubes "by the tonnes". Although, personally, I didn't even know they sold ice-cubes in a plastic bags at the store.
