            RE: Classification of Dipyridamole from China

            Dear Mr. Ranieri:

                 Your letter of April 13, 1989, concerns the classification
            of Dipyridamole.

            FACTS:

                 Dipyridamole, a coronary vasodilator, is described as
            containing two pyrimidine rings and two hydrogenated rings.

            ISSUE:

                 The classification of Dipyridamole under the Harmonized
            Tariff Schedule of the United States (HTSUS).

            LAW AND ANALYSIS:

                 Although Dipyridamole contains two pyrimidine rings, it is
            not considered an aromatic chemical for classification purposes
            under the HTSUS.  Additional U.S. Note 2(b), Section VI, HTSUS,
            in defining the term "modified aromatic" states that the term
            does not include any molecular structure in which one or more
            pyrimidine rings are the only modified aromatic rings present.
            Therefore, because of it structure, Dipyrimidine would not be
            considered an aromatic drug for tariff purposes.

                 Dipyridamole is classifiable under the provision for other
            heterocyclic compounds containing a pyrimidine ring (whether or
            not hydrogenated) in the structure: drugs, in subheading
            2933.59.3000, HTSUS.















                                         - 2 -

            HOLDING:

                 Dipyridamole is classifiable in subheading 2933.59.3000,
            HTSUS.  The rate of duty is 3.7 percent ad valorem.

                                        Sincerely,




                                        John Durant, Director
