ITEM 4.01  Change in Registrant’s Certifying Accountant

(a) Previous independent registered public accounting firm

On December 14, 2006, the Board of Directors of California Steel Industries, Inc. (“Company”) dismissed PricewaterhouseCoopers LLP (“PwC”) as its independent registered public accounting firm.

PwC will continue as the independent registered public accounting firm for the Company until PwC completes its procedures on (i) the financial statements of the Company as of and for the fiscal year ending December 31, 2006 and (ii) the Company’s Form 10-K in which such financial statements will be included.

PwC’s reports on the Company’s financial statements for the fiscal years ended December 31, 2005 and 2004 did not contain an adverse opinion or disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principle.

During the fiscal years ended December 31, 2005 and 2004 and through December 14, 2006, there were no disagreements with PwC on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of PwC, would have caused PwC to make reference thereto in connection with their reports on the Company’s financial statements for such years.

During the fiscal years ended December 31, 2005 and 2004 and through December 14, 2006, there have been no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided PwC with a copy of the above disclosures and has requested that PwC furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of the PwC letter dated December 14, 2006 is attached to this report as Exhibit 16.1.

(b) New independent registered public accounting firm

On December 14, 2006, the Board of Directors approved the appointment of a new registered public accounting firm as the Company’s independent registered public accounting firm for the year ending December 31, 2007, however, acceptance of such appointment is subject to completion of such firm’s client intake procedure. The Company will announce the appointment upon formal acceptance by such firm via an amendment to this Form 8-K. During the years ended December 31, 2005 and 2004 and through December 14, 2006, there were no consultations with such firm pursuant to Item 304(a)(2)(i) and (ii) of Regulation S-K.
