            RE:  Continuous Casting Plant
            Dear Mr. Givens:
                 Your letter of July 26, 1990, on behalf of Golden Aluminum
            Company, Lakewood, Colorodo, concerns the tariff status of the
            Lauener block caster/reduction/coiler plant.  Additional
            information was submitted in the form of a meeting in our
            office, supplemental brief, blueprints, color photographs, and
            a video cassette.
                 Our previous ruling to you, dated June 7, 1990 (086736),
            addressed the tariff status of the caster unit, reduction
            group, and tandem coilers.  Lacking sufficient information, we
            were unable to consider the remaining components.  You
            specifically ask that we reconsider the issue of whether the
            entire plant, the components of which you now state will be
            imported in the same shipment, is a composite machine for
            tariff purposes, and also that we address the status of the
            steel foundation parts which support the plant.
            FACTS:
                 The material appearing under FACTS in the June 7 letter is
            incorporated by reference in this decision.  The additional
            components we were unable to consider previously consist of the
            plant's hydraulics (the system of pumps and tanks containing
            fluids which supply the power for the machinery), a roller-type
            conveyor for moving the aluminum slab from the reduction group
            through the edge trimmer to the shear then to the tandem
            coilers, and the plant's programmable controlling apparatus in
            the form of a console with keyboards and CRTs, designed to
- 2 -
            control the plant's entire operation.  However, the steel
            foundation which you previously stated was to be imported
            separately, will now be imported in the same shipment with all
            the components necessary to complete the plant.
                 The steel foundation is described as a series of masts and
            tie-in frames.  The masts are vertical support elements
            consisting of a series of welded plates.  H or I beams attach
            to these masts and bear the weight of the plant's components
            which rest on them.  The bottom of each mast attaches to a
            tie-in frame which is a steel plate bolted to the concrete
            floor.  The masts and tie-in frames support and stabilize the
            beams.  The masts and tie-in frames supporting the
            tundish/caster unit also contain hydraulic lifting mechanisms
            which allow that unit to be tilted at various angles.  This
            permits the hot aluminum slab to be control cooled by adjusting
            the speed at which it passes through the chilling blocks.  The
            rate at which the slab is allowed to cool depends on the
            particular aluminum alloy being used.  Assemblies of masts,
            tie-in frames and beams run the entire length of the composite
            plant on both sides, from the tundish/caster to the tandem
            coilers.  These parallel assemblies are connected by a series
            of beams running perpendicular between them.
            ISSUE:
                 Whether the plant components, as described, constitute a
            composite machine for tariff purposes.
            LAW AND ANALYSIS:
                 Merchandise is classifiable under the HTSUSA in accordance
            with the General Rules of Interpretation (GRIs).  GRI 1 states
            that for legal purposes, classification shall be determined
            according to the terms of the headings and any relative section
            or chapter notes and, provided the headings or notes do not
            provide otherwise, according to GRIs 2 through 6.
                 Section XVI, Note 3, HTSUSA, states in part that composite
            machines consisting of two or more machines fitted together to
            form a whole and other machines adapted for the purpose of
            performing two or more complementary or alternative functions
            are to be classified as if consisting only of that component of
            as being that machine which performs the principal function.
                 The Explanatory Notes (ENs) which constitute the Customs
            Cooperation Council's official interpretation of the Harmonized
            System, at p. 1133 explain General Explanatory Note 3 to
            Section XVI and state that for the purposes of [the provisions
- 3 -
            relating to composite machines and multi-function machines],
            machines of different kinds are taken to be fitted together to
            form a whole when (1) incorporated one in the other or (2)
            mounted one on the other, or (3) mounted on a common base or
            frame or in a common housing (emphasis original).  The ENs
            continue by stating that floors, concrete bases, walls,
            partitions, ceilings, etc., even if specially fitted out to
            accomodate machines or appliances, should not be regarded as a
            common base joining such machines or appliances to form a
            whole.
                 Our June 7 ruling was predicated on the lack of evidence
            of sufficient structural interrelationship of the plant's
            components to warrant the conclusion that they were
            incorporated one in the other for purposes of note 3.  We now
            find from the additional material submitted that the components
            arriving in the same shipment are mounted on a common base or
            frame for purposes of note 3.  Therefore, we find that the
            components of the casting plant constitute a composite machine
            whose principal function is the casting of aluminum slab.
            HOLDING:
                 Under the authority of Section XVI, Note 3, the
            tundish/caster unit, shears, reduction group, edge trimmer,
            tandem coilers, conveyor, hydraulics, programmable controlling
            apparatus and steel framework, as described, all of which are
            imported in the same shipment, are provided for free of duty in
            heading 8454 as a casting machine of a kind used in metal
            foundries.  Actual classification is in subheading
            8454.30.0090, HTSUSA.
                                        Sincerely,
