The raw materials are the first products on which financial transactions are made. It is a deliverable that has futures trading desk and spot trading desk with physical delivery of the products as is the case with our company. We know that since the contracts of purchase and sale of raw materials to delivery of finished products (ingots and ingots) to end customers can spend 3 or 4 months in which there is a fluctuation in prices that can ruin an operation sign success. Within Neiman Group we have a wide expertise in conducting financial transactions on commodities as well as privileged access to all major platforms and markets for them.
