Frequently Asked Questions

Q: How do I become a Cerrejón supplier?
A:Cerrejón does not store a list of potential suppliers on its system. This information is managed by purchase analysts on each area. You can send information about your company through our website to the analyst responsible for each purchase line by filling in the purchase lines form.

Q: How do I know if I am on the Cerrejón supplier list?
A: Cerrejón only enters into the system those suppliers that have been approved through the purchasing and contracting processes. If your company has been approved through the purchase and contracting process within the last 12 months, you are entered into the system, and your details are active. If you are not entered in the system, or your details are not active, it does not mean that you will not be considered for the purchase and contracting process as this entry and activation is solely for placing orders for purchases/contracts and for the payment of invoices.
