                       OF THE SARBANES-OXLEY ACT OF 2002

I, Kerry A. Shiba, certify that:

     1. I have reviewed this report on Form 10-Q of Kaiser Aluminum Corporation;

     2. Based on my knowledge, this report does not contain any untrue statement
of a material fact or omit to state a material fact necessary to make the
statements made, in light of the circumstances under which such statements were
made, not misleading with respect to the period covered by this report;

     3. Based on my knowledge, the financial statements, and other financial
information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the registrant as
of, and for, the periods presented in this report;

     4. The registrant's other certifying officers and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) [text omitted in accordance with SEC
transition instructions set forth in SEC Release No. 34-47986] for the
registrant and we have:

          (a) designed such disclosure controls and procedures, or caused such
     disclosure controls and procedures to be designed under our supervision, to
     ensure that material information relating to the registrant, including its
     consolidated subsidiaries, is made known to us by others within those
     entities, particularly during the period in which this report is being
     prepared;

          (b) [paragraph omitted in accordance with SEC transition instructions
     set forth in SEC Release No. 34-47986]

          (c) evaluated the effectiveness of the registrant's disclosure
     controls and procedures and presented in this report our conclusions about
     the effectiveness of the disclosure controls and procedures as of the end
     of the period covered by this report based on such evaluation; and

          (d) disclosed in this report any changes in the registrant's internal
     control over financial reporting that occurred during the registrant's most
     recent fiscal quarter (the registrant's fourth fiscal quarter in the case
     of an annual report) that has materially affected, or is reasonably likely
     to materially affect, the registrant's internal control over financial
     reporting.

     5. The registrant's other certifying officers and I have disclosed, based
on our most recent evaluation of internal control over financial reporting, to
the registrant's auditors and the audit committee of the registrant's board of
directors (or persons performing the equivalent function):

          (a) all significant deficiencies and material weaknesses in the design
     or operation of internal control over financial reporting which are
     reasonably likely to adversely affect the registrant's ability to record,
     process, summarize and report financial information; and

          (b) any fraud, whether or not material, that involves management or
     other employees who have a significant role in the registrant's internal
     control over financial reporting.
