RE: The tariff classification of a thermal reactor and a
hybridization incubator from Canada.
Dear Ms. Campanian:
In your letter dated October 17, 1991 on behalf of Tyler
Research Instruments Corporation you requested a tariff
classification ruling.
The TR-96 Thermal Reactor provides an easily programmable
environment for any chemical or enzyme-mediated reactions
requiring accurately controlled thermal cycling. It is capable
of a virtually unlimited number of rapid and accurate temperature
changes from 5 degrees C above ambient to 100 degrees C. The
heart of the TR-96 is the sealed combustion chamber containing an
intricate network of pressurized channels whose function is to
minimize thermal mass and, therefore, sluggish response. Paired
high performance turbines generate a controlled turbulent flow of
air, the temperature of which is precisely regulated by a
computer (not imported) operating through a series of multiple
feedback sensing loops. The reactor comes equipped with a
standard 88 x 0.5ml microfuge tube tray.
Additional tube trays that vary in position numbers and tube
capacity: TR-96.01.88, TR-96.01.60 and TR-96.01.96 will be
imported, as well as Thermal Sensing Device TSD-08, which has 8
solid state AD590JH thermal sensors.
Also imported will be Hybridization Incubator HI-12000 with
a 12 liter chamber and 6-position rotating carousel. Operating
on the same principle as the TR-96 Thermal Reactor, the HI-12000
Hybridization Incubator bathes the sample cassettes in a
controlled turbulent flow of air, the temperature of which is
precisely regulated by an integrated solid state controller.
Additional sample cylinders, HI-12000.11 and HI-12000.12, will
also to be imported.
The applicable subheading for the TR-96 Thermal Reactor and
the HI-12000 Hybridization Incubator will be 8419.89.5075,
Harmonized Tariff Schedule of the United States (HTS), which
provides for laboratory equipment, whether or not electrically
heated, for the treatment of materials by a process involving a
change of temperature such as heating. The rate of duty will be
4.2 percent ad valorem. The applicable subheading for the
reactor tube trays TR-96.01.88, TR-96.01.60 and TR-96.01.96, and
for the incubator sample cylinders HI-12000.11 and HI-12000.12
will be 8419.90.9060, which provides other parts of laboratory
equipment, for the treatment of materials by a process involving
a change of temperature such as heating. The rate of duty will
be 4.2 percent ad valorem.
The applicable subheading for Thermal Sensing Device TSD-08
will be 9025.19.0080, which provides for thermometers, not
combined with other instruments, other than liquid-filled for
direct reading. The rate of duty will be 5 percent ad valorem.
Goods classifiable under subheadings 8419.89.5075 and
8419.90.9060, HTS, which have originated in the territory of
Canada, will be entitled to a 1.6 percent rate of duty under the
United States-Canada Free Trade Agreement (FTA) upon compliance
with all applicable regulations. Those classifiable under
9025.19.0080, HTS, will be entitled to a 3.5 percent rate of duty
under the agreement.
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
Area Director
