In 2004, purchases by the EU chemical industry accounted for 74% of the sales value. The remaining 26% constitutes the gross value added of the sector, which comprises gross operating surplus and payroll. Among purchases, it is possible to single out the costs of trading and energy. Trading represents the cost of chemicals purchased from third parties and resold in their original condition, and amounts to 4% of the sales value. Energy costs from the purchase of feedstock and fuel and power currently account for 8% of the sales value. However, it needs to be underlined that this is an average.
