Prospective Supplier Registration 

(Versión Español)

Suppliers interested in working with Oxy should begin the prospective supplier registration by following the steps outlined below. Registration is a simple process intended for use by suppliers seeking to do business with Oxy. Please note that completing the prospective supplier registration does not imply a contract, or intent to purchase goods or services from prospective suppliers by Oxy.


1. Carefully read the iSupplier Portal User Guide - Submit Prospective Supplier Registration Form.

2. Select the appropriate Oxy Subsidiary/Country and complete the Prospective Supplier Registration Form.

If you currently have operations in multiple countries under one legal entity, select only the primary Oxy Subsidiary/Country. Submit only one form for each legal entity of your organization that desires to do business with Oxy.

3. Complete the survey included in the Prospective Supplier Registration Form. Requests without completed surveys will automatically be rejected.

4. If there is interest from Oxy, you will receive an automatic email notification that your company has been registered and given access to the iSupplier Portal to provide additional information.

Registered suppliers will be inactivated if they do not provide the requested information or if they are not able to comply with Oxy’s policies and procedures.
