RE:  Chemicals. L-Tyrosine;NYRL 832934 modified.

Dear Mr. Holzapfel:

     In a ruling letter (NYRL 832934), dated November 10, 1988,
our New York office provided you with a tariff classification of
certain chemicals from Taiwan and Japan under the Harmonized
Tariff Schedule of the United States Annotated (HTSUSA).

FACTS:

     Among the chemicals listed was L-Tyrosine, which was
classified in subheading 2922.50.50, HTSUSA.  That classification
was based upon an improper CAS number.  The correct CAS number
for L-Tyrosine is 60-18-4.

ISSUE:


Was our classification wrong?

LAW AND ANALYSIS:

     L-Tyrosine is an amino-acid-phenol more properly
classifiable in subheading 2922.50.40, HTSUSA, as an aromatic
compound, whose CAS number is listed in the chemical appendix to
the tariff schedules.  The corresponding rate of duty is 3.7
cents per kilogram, plus 15.6 percent ad valorem.

HOLDING:

     NYRL 832934 is modified accordingly.


                              Sincerely,



                              John Durant, Director
