RE: The tariff classification of infrared detectors from France
Dear Mr. Hofheimer:
In your letter dated January 23, 1989 you requested a tariff
classification ruling.
Your letter describes the infrared detector, identified in
the submitted literature as a photovoltaic mercury-cadmium-
telluride or indium antimonide diode housed in a dewer of glass
or stainless steel. The purpose of the dewer is to cool the
diode which is designed to operate at the temperature of liquid
nitrogen (77K). The diode can be a single or multi-element
device on a single crystal chip. The multi-element device is a
diode array in which the diodes are diffused on a single crystal
chip.
The applicable subheading for the single-element
photovoltaic detector will be 8541.40.6050, Harmonized Tariff
Schedule of the United States (HTS), which provides for "diodes,
other than light emitting diodes or solar cells," free of duty.
The applicable HTS subheading for the multi-element
photovoltaic detector will be 8541.50.0080, which provides for
"Other semiconductor devices." The rate of duty will be 1
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
