RE: The tariff classification of the "Transfluid" hydraulic shaft
coupling from Italy
Dear Ms. Brown:
In your letter dated December 22, 1992, on behalf of your
client, Kraft Power, Division of W.A. Kraft Corp., you requested
a tariff classification ruling.
The items involved in this request are a series of hydraulic
transmission couplings. They consist of a driving impeller (pump)
mounted on the input shaft; a driven impeller (turbine) mounted on
the output shaft; and a cover, flanged to the output impeller, with
an oil-tight seal. This coupling functions by using the input
torque from an external power source (electric motor or diesel
engine) to rotate the driving impeller. The impeller transmits
kinetic energy to the oil in the coupling. The oil moves by
centrifugal force across the blades of the driven impeller
(turbine) toward the outside of the coupling. The turbine absorbs
the force of the oil and develops its own rotational torque,
thereby turning the output shaft.
The purpose of the coupling is not to alter speed or torque,
which it can not do, but to provide a rotational buffer between a
motor and its output shaft (or transmission). In other words, it
provides a "soft" start that places less stress on both the motor
and the transmission.
The applicable subheading for the Transfluid coupling will be
8483.60.8000, Harmonized Tariff Schedule of the United States
(HTS), which provides for other shaft couplings. The rate of duty
will be 5.7 percent ad valorem.
This ruling is being issued under the provisions of Section
177 of the Customs Regulations (19 C.F.R. 177).
A copy of this ruling letter should be attached to the entry
documents filed at the time this merchandise is imported. If the
documents have been filed without a copy, this ruling should be
brought to the attention of the Customs officer handling the
transaction.
Sincerely,
Jean F. Maguire
