Ladies and Gentlemen:

      Pursuant to Rule 477 promulgated under the Securities Act of 1933, as
amended (the "Act"), Phibro Animal Health Corporation (the "US Issuer") and
Philipp Brothers Netherlands III B.V. (the "Dutch Issuer" and with US Issuer,
the "Issuers"), and Prince Agriproducts, Inc., Phibro-Tech, Inc., Phibro Animal
Health U.S., Inc., Phibro Animal Health Holdings, Inc., Phibrochem, Inc., C P
Chemicals, Inc., Phibro Chemicals, Inc., Western Magnesium Corp., and Phibro
Animal Health SA (collectively the "Guarantors" and with the Issuers, the
"Registrants"), hereby make this application to withdraw the Registration
Statement on Form S-4 (Registration Nos. 333-112942 and 333-112942-01 through
112942-10), together with all exhibits thereto (the "Registration Statement").
The Registration Statement was originally filed by the Registrants with the
Securities and Exchange Commission (the "Commission") on February 18, 2004.

      The Registration Statement relates to a proposed exchange offer by the
Issuers for units consisting of 13% senior secured notes due 2007. The
Registrants are requesting withdrawal of the Registration Statement because they
do not currently intend to conduct the exchange offer as contemplated by the
Registration Statement due to changed circumstances since the filing of the
Registration Statement. The financial statements contained in the Registration
Statement are stale and it has not been declared effective by the Commission. No
securities have been sold or exchanged in connection with the transactions
contemplated by the Registration Statement. The



Registrants may undertake a subsequent private offering of securities in
reliance on Rule 155(c) of the Act.

      Accordingly, the undersigned, on behalf of the Registrants, hereby
respectfully requests that a written order granting the withdrawal of the
Registration Statement be issued by the Commission as soon as possible.

      The undersigned also requests on behalf of the Registrants, in accordance
with Rule 457(p) promulgated under the Act, that all fees paid by the Issuers to
the Commission in connection with the filing of the Registration Statement be
credited to the account of the Issuers for future use by the Issuers or any
majority-owned subsidiary of the Issuers. Please fax a copy of the written order
as soon as it is available to the undersigned, at (212) 754-0330. It is our
understanding that this application for withdrawal of the Registration Statement
will be deemed granted on the date that it is filed with the Commission unless,
within fifteen (15) days after such date, the Registrant receives notice from
the Commission that this application will not be granted.

      If you should have any questions regarding this application, please do not
hesitate to contact me at 212-907-7300.

                                                     Very Truly Yours,

                                                     /s/ Richard S. Kaplan
