Classification of Supermizer - SMX
Circular No. 45 dated 19th
May 1995
Please refer to
correspondence regarding the classification of the above-mentioned apparatus
under Schedule - I, CTA '75 (Customs House File No. S/26-Misc - 3336/ 94 VB).
On the basis of
technical write-up/ literature submitted, it is observed that the article is an
induction motor control apparatus comprising of a convertor, and inverter, a
current detection device, a voltage detection device, an overheating device, a
Central Processing Unit, a Pulse Width Modulation circuit and an operating
panel. It controls the power factor of a three-phase induction motor when
converting electrical energy in order to drive the said motor. The converting
function is performed by rectification of the input alternating current to
direct current, which is subsequently inverted to alternating current of
variable frequency and voltage. The controlling function is performed by
controlling the power factor of the controlling function is performed by
controlling the power factor of the induction motor by comparing the actual
against a preset power factor.
The Board has
examined the classification of the above-mentioned product.
Heading
85.04: This
heading provides, in part, for "electrical static converters". The
"Supermizer- SMX" however, besides having the function of a static
convertor also contains measuring devices, control devices and operating devices
and therefore, it is more than a static convertor. Hence its classification
under Heading 85.04 is not appropriate.
Heading No.
90.32: In
accordance with Note 6(B) to Chapter 90, Heading 90.32 covers, inter alia, the
"Automatic regulators of electrical quantities". Furthermore, as per
Explanatory Note to Heading 90. (Page 1535-1536) "The automatic regulators
of this heading are intended for use in complete automatic control system which
are designed to bring a quality, electrical or non- electrical, to and maintain
it at, a desired value stabilised against any disturbances, by constantly
measuring its actual value."
The apparatus in
question meets the term of heading 90.32 and note 6 (B) to Chapter 90 since it
contains measuring devices, control devices and switching devices and controls
the power factor of the induction motor. Accordingly, the Board is of the view
that this item would be classifiable u/h 90.32 (sub-heading 9032.89). Since the
apparatus is classifiable under heading 9032.89, its classification under
heading 85-43 is ruled out by application of rules 1 and 6 of the General
Interpretative Rules.
