RE:	American Depositary Shares
evidenced by the American Depositary Receipts for
Ordinary Shares, Series B  of Sociedad Quimica y
Minera de Chile S.A. (F-6 File No.:   33-67156)


Ladies and Gentlemen:

Pursuant to Rule 424(b)(3) under the Securities Act
of 1933, as amended, on behalf of The Bank of New
York, as Depositary for securities against which
American Depositary Receipts (ADRs) are to be
issued, we attach a copy of the new prospectus
(Prospectus) reflecting the change in the number of
Sociedad Quimica y Minera de Chile S.A., Series B
Ordinary Shares represented by one American
Depositary Share (the Ratio) from one (1) ADS
represents 10 Series B Ordinary Shares to one (1)
ADS represents one (1) Series B Ordinary Share.

As required by Rule 424(e), the upper right hand
corner of the Prospectus cover page has a reference
to Rule 424(b)(3) and to the file number of the
registration statement to which the Prospectus
relates.

Pursuant to Section III B of the General Instructions
to the Form F-6 Registration Statement, the
Prospectus consists of the ADR certificate for
Sociedad Quimica y Minera de Chile S.A., Series B.
The Prospectus has been revised to reflect the new
Ratio, and has been overstamped with:

Effective March 28, 2008, One (1) ADR equals One
(1) Series B Ordinary Share.

Attached to this letter is a copy of a letter from
Sociedad Quimica y Minera de Chile S.A.,  to The
Bank of New York requesting that the Ratio be
changed.

Please contact me with any questions or comments
at (212) 815 4244.

Sincerely,


Sandra Friedrich
