Dear Sir:

     This is a decision on a protest filed May 6, 1991, against
your decision in the classification of merchandise liquidated
February 8, 1991.

FACTS:

     The protestant entered all goods in subheading 2916.19.5000,
Harmonized Tariff Schedule of the United States Annotated
(HTSUSA), a provision for unsaturated acyclic monocarboxylic
acids, their peroxides and peroxyacids, other, eligible for duty
free treatment as a product of Mexico, a beneficiary country
under the Generalized System of Preferences.

     The merchandise was reclassified in subheading 3815.90.5000,
HTSUSA, as a mixture of two separate chemically defined compounds
that made up a reaction initiator not elsewhere specified or
included, other, and the rate was advanced to 5% ad valorem.

     The protestant now claims that the merchandise is properly
classifiable under subheading 2915.90.5000, HTSUSA, a provision
for saturated acyclic monocarboxylic acids and their peroxides
and peroxyacids, other, dutiable at the general rate of 3.8% ad
valorem but eligible for duty free treatment as a product of
Mexico, a beneficiary country under the Generalized System of
Preferences.

     Customs laboratory report of a sample taken from the subject
importation indicates that the product has the characteristics of
t-butyl peroxyacetate in a hydrocarbon solvent matrix, that t-
butyl peroxyacetate is a saturated, non-aromatic ester derivative
of a peroxyacid and that the composition of the sample is
consistent with the manufacturer's claim of approximately 50% t-
butyl peroxyacetate by weight.  The report notes classification
in subheading 2915.90.5000, HTSUSA, as appropriate.

ISSUE:

     What is the proper classification under the HTSUSA of
Lupersol 75M, a 50% solution of t-butyl peroxyacetate and mineral
spirits?

LAW AND ANALYSIS:

     Merchandise imported into the U.S. is classified under the
HTSUSA.  Tariff classification 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.

     Generally, only separate chemically defined compounds fall
to be classified under any of the headings of Chapter 29 of the
Schedule. Note 1(a), Chapter 29, HTSUSA.  An appropriate heading,
if any, of Chapter 29 would apply, however, to separate
chemically defined organic compounds dissolved in other solvents,
provided that the solution constitutes a normal and necessary
method of putting up these products adopted solely for reasons of
safety or for transport and that the solvent does not render the
product particularly suitable for specific use rather than for
general use. Note 1(e), Chapter 29, HTSUSA.

     The U.S. Department of Transportation strictly regulates the
transportation of t-butyl peroxyacetate.  See Final Rule
published in Federal Register, Friday, December 21, 1990, 52402,
revising Part 173 to Title 49, Code of Federal Regulations.  T-
butyl peroxyacetate in concentrations of not-more-than 52% must
be diluted in solvent of not-less-than 48% when packaged and
offered for transportation, id. at 52656.

     We are of the opinion that t-butyl peroxyacetate is a
separate chemically defined compound that in this case has been
dissolved in mineral spirits in a normal and necessary method of
putting it up, solely for reasons of safety or transport, and in
such a way that the mineral spirits do not render the t-butyl
peroxyacetate suitable for a specific use.  The subject
merchandise is described under heading 2915, HTSUSA, a provision
for saturated acyclic peroxyacids.

HOLDING:

     The protest should be allowed.

     Lupersol 75M, a 50% solution of t-butyl peroxyacetate and
mineral spirits is classifiable under subheading 2915.90.5000,
HTSUSA, a provision for saturated acyclic monocarboxylic acids
and their peroxyacids; other; other; other.

     Articles classified under that subheading for the year 1991
were subject to a general rate of duty of 3.8% ad valorem and
products of Mexico classifiable thereunder were eligible for
duty-free treatment under the Generalized System of Preferences
(GSP), upon compliance with applicable law and Customs
Regulations.

     A copy of this decision should be attached to the Customs
Form 19 and provided to the protestant as part of the notice of
action on the protest.

                           Sincerely,



                           John Durant, Director
                           Commercial Rulings Division
