Can someone explain to me how do trade companies operate? They claim they have bought allocations in mills accross the world or special contracts with the supplier mills and are able to offer cement with prices 60-80 usd/mt CIF ASWP.  Please explain to me in details how this is possible and how such business operates? The companies really do exists and claim to have many successful deliveries and decades of history in the market. Hope comone will give me a comment soon.
