Re: The tariff classification of optical isolators from Japan
Dear Mr. Nakada:
In your letter dated June 9, 1994, you requested a tariff
classification ruling.
Optical Isolators are used in laser semiconductor devices.
An optical isolator is composed of a Faraday Rotator, a polarizer,
a permanent magnet, and an analyzer with a holder. The polarizer
is an optical element; it is a miniature glass element
incorporating a silver matrix to polarize light. The optical
isolator is designed to transmit a forward beam and shut off a
backward beam in optical communication devices and in optical
measuring instruments.
The applicable subheading for the optical isolator will be
9013.80.6000, Harmonized Tariff Schedule of the United States
(HTS), which provides for other optical appliances and instruments,
not specified or included elsewhere in this chapter, other devices,
appliances and instruments, other. The rate of duty will be 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
