The daily copper quotation is determined on the stock exchange.
Based on the stock exchange quotation, the DEL quotation valid in Germany is formed. The DEL quotation is the basis for the calculation of cables with copper content at bda connectivity.
Due to large fluctuations in the copper price, the price of components with a high copper content usually consists of a basic price plus copper surcharge. This surcharge results from the difference between the daily price and the copper base (1.50 €/kg).
Unless otherwise agreed, the copper surcharge is calculated at the daily price (price of the day before the clarified order receipt). The daily price of the copper quotation is published every working day on our website www.bda-connectivity.com.
The product of the copper price and the difference between the daily price/kg and the base price (1.50 €/kg) results in the copper surcharge; this is shown separately on the invoice.
Copper sales factor [kg/m] * ( daily price – 1.50) [€/kg]) = Copper surcharge [€/m])
1000m cable with 0.1 kg/m copper content costs 2500€ plus copper surcharge, this price is based on a copper base of 1.50€/m. With a current copper quotation of 6.20 €/kg, this results in a copper surcharge of 370 € and a total price of 2870 €.
(calculation: 2500€ + (6,20€/kg – 1,50€/kg) x 0,1 kg/m x 1000m = 2870 €)
Copper Sales Factor
The copper sales factor is defined by the use of copper per meter of cable [in kg/m].
The German Electrolytic Copper Listing for conducting material (DEL listing) is a price quotation for copper for conducting purposes (purity 99.5 %) which is dependent on the stock exchange. In cable and wire production, it is an important parameter for calculating the current daily price.
