RE: The tariff classification of a mixer and a screening machine
from Canada
Dear Mr. Ackerman:
In your letter dated August 27, 1991 on behalf of Ingersoll-
Rand Company you requested a tariff classification ruling.
The Hi-Shear Mixer is used in pulp mills to mix gaseous or
liquid chemicals with medium consistency pulp stock. It
basically consists of a stainless steel or titanium-lined steel
housing, a rotor, mixing rings, and a motor and drive. Pulp
stock enters radially through an inlet at the periphery of the
rotor, while the chemicals are injected through a separate
inlet. The stock and chemicals are subjected to intense
turbulence as they pass between the rotor and vanes on the
stationary mixing rings, causing a rapid dispersion of the
chemicals throughout the stock. Tramp metals and other rejected
materials exit through a junk trap connection.
The Hi-Q Fine Screen is also used in pulp mills to remove
contaminants from pulp stock. It consists basically of a housing
with a rotor, a cylindrical screen plate, and compartments for
accepted and rejected materials. The stock flows into the inlet
compartment where tramp material is separated and accumulated in
a junk trap for intermittent dumping. The stock then flows over
a dam and into the screening zone between the spinning rotor and
the stationary screen basket. The rotor accelerates the stock
through myriad small holes or slots in the screen, while dirt,
shives, and other foreign matter too large to pass through are
collected in a reject compartment for discharge. The rotor is
specially designed to prevent flocculation (the tendency of the
pulp fibers to clump together) and to keep the screen plate from
clogging.
The applicable subheading for the Hi-Shear Mixer and the Hi-
Q Fine Screen will be 8439.10.00, Harmonized Tariff Schedule of
the United States (HTS), which provides for machinery for making
pulp of fibrous cellulosic material. The rate of duty will be
free.
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
