Sunflower oil importing Spain

My name is D*********z and I represent a Cuban company that is looking for suppliers to import into Cuba.
As a first step, we will purchase 25 tons of sunflower oil, but we believe that according to demand we will reach 50 tons per month. The containers we need are 1 liter bottles.
At this moment we are contacting different suppliers and starting negotiations to find our best option in terms of quality, safety and price of the merchandise.
If it is not too much trouble we would like to receive a quote for 25 tons of sunflower oil with CIF price
