RE: The tariff classification of Langmuir-Blodgett troughs from
England
Dear Mr. Dodd:
In your letter dated December 23, 1992 you requested a
tariff classification ruling.
In an earlier ruling letter issued by this office, file NY
853325 dated June 25, 1990, you were advised that certain
Langmuir-Blodgett troughs were classifiable in the provision for
other machines and mechanical appliances having individual
functions, not specified or included elsewhere in subheading
8479.89.9090, Harmonized Tariff Schedule of the United States.
In your letter of December 23, 1992 you have stated that the
name of your firm has been changed from Connecticut Technology
Consultants, Inc. to CTC Technologies, Inc. You have also stated
that the model numbers which were the subject of the earlier
ruling letter have been replaced by new model numbers. In view
of these changes, you have requested a ruling letter on the
current models of Langmuir-Blodgett troughs your from imports.
The imported Langmuir-Blodgett troughs consist of
rectangular series 600 troughs and modular system 2000 troughs.
There are three models of the series 600 troughs. Model 601S is
a manually operated student analytical film balance for
undergraduate experiments on ultra-thin organic films grown on
liquid surfaces. It consists of a trough with a manually
operated barrier, a surface pressure sensor and display unit, an
acrylic dust cover, a monolayer kit and instruction manual.
Model 601A is a computer controlled analytical film balance. It
is similar to model 601S, but also contains a temperature
controllable trough, motor driven barrier, and a computer
interface unit. Model 601M is a miniature thin film balance used
on a stage of a microscope for observation of changes during film
compression. The trough allows symmetrical compression of the
monolayer in the field of view of the microscope's objective
lens, and contains a 25 millimeter sapphire window for
transmission microscopy or illumination. These three units lack
a motorized dipping mechanism and thus are unable to deposit the
film onto a substrate.
Models 611 and 622 are troughs which contain a dipper
mechanism and thus are used to transfer the ultra-thin films onto
substrates; the former is used for the deposition of conventional
Langmuir-Blodgett layers onto substrates, while the latter
contains two trough compartments, two pressure sensors, and two
dipper mechanisms and thus can deposit any sequence of alternate
Langmuir-Blodgett layers.
Four models of the series 2000 Langmuir-Blodgett troughs
exist. Model 2001, which does not contain a dipper mechanism,
allows comprehensive analysis of isotherms. Models 2011 and 2022
are analogous to models 611 and 622 in that they are used for
deposition of single or alternate layers. Finally, model 2032
can perform deposition of either single layers or a sequence of
alternate multiple layers.
The applicable subheading for the models 611, 622, 2011,
2022, and 2032 Langmuir-Blodgett troughs will be 8479.89.9099,
Harmonized Tariff Schedule of the United States (HTS), which
provides for other machines and mechanical appliances having
individual functions, not specified or included elsewhere. The
rate of duty will be 3.7 percent ad valorem.
The applicable subheading for model 601M Langmuir-Blodgett
trough will be 9011.90.0000, HTS, which provides for accessories
for compound optical microscopes. The rate of duty will be 7.2
percent ad valorem.
The applicable subheading for the models 601S, 601A, and
2001 Langmuir-Blodgett troughs will be 9027.80.4060, HTS, which
provides for other electrical instruments for physical analysis.
The rate of duty will be 4.9 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
