Re:  5-methoxy-2-mercapto benzimidazole; CAS 37052-78-1; DD
     875181 modified

Dear Mr. Thompson:

     This is in further reply to your letter dated June 5, 1992,
in which you requested from our Los Angeles office a binding
ruling on the classification of several chemical products.  In
response to that request, DD 875181 was issued.

     This is also a decision on a reconsideration of DD 875181
(June 26, 1992), which classified 5-methoxy-2-mercapto
benzimidazole under subheading 2930.90.2000, Harmonized Tariff
Schedule of the United States Annotated (HTSUSA), generally
dutiable at 6.7 percent ad valorem.

FACTS:

     The merchandise is identified as 5-methoxy-2-mercapto
benzimidazole.  It bears the CAS Registry number 37052-78-1.

ISSUE:

     What is the proper classification under the HTSUSA of 5-
methoxy-2-mercapto benzimidazole, CAS Registry No. 37052-78-1?

LAW AND ANALYSIS:

     Merchandise imported into the U.S. is classified under the
HTSUSA.  The tariff classification of merchandise under the
HTSUSA is governed by the principles set forth in the General
Rules of Interpretation (GRIs) and, in the absence of special
language or context which otherwise requires, by the Additional
U.S. Rules of Interpretation.  The GRIs and the Additional U.S.
Rules of Interpretation are part of the HTSUSA and are to be
considered statutory provisions of law for all purposes.

     GRI 1 requires that classification be determined first
according to the terms of the headings of the tariff schedule and
any relative section or chapter notes and, unless otherwise
required, according to the remaining GRI's taken in order.

     Upon reconsideration of the issue, we are of the opinion
that heading 2933, a provision for heterocyclic compounds with
nitrogen hetero-atom(s) only, is more specifically descriptive of
the product than is heading 2930, a provision for organo-sulfur
compounds.

HOLDING:

     5-methoxy-2-mercapto benzimidazole, CAS Registry No. 37052-
78-1, is classifiable under subheading 2933.90.8000, which
provides for heterocyclic compounds with nitrogen hetero-atom(s)
only; nucleic acids and their salts; other; aromatic or modified
aromatic; other; other products described in additional U.S. note
3 to section VI, HTSUSA.

     Merchandise classified under this subheading is subject to
the column 1 general rate of duty of 13.5% ad valorem.

     This decision should be considered a modification of DD
875181 pursuant to 19 CFR 177.9(d)(1).  It is not to be applied
retroactively to DD 875181 (19 CFR 177.9(d)(2)) and will not,
therefore, affect past transactions for the importation of your
merchandise under that ruling.  For purposes of future
transactions in merchandise of this type, DD 875181 will not be
valid precedent.  We recognize that pending transactions may be
adversely affected by this modification, in that current
contracts for importations arriving at a port subsequent to this
decision will be classified pursuant to it.  If such a situation
arises, you may notify this office and apply for relief from the
binding effects of this decision as may be warranted by the
circumstances.

                           Sincerely,



                           John Durant, Director
                           Commercial Rulings Division
