RE: The tariff classification of high voltage solid state relays from
Thailand and Malaysia
Dear Ms Gill.:
In your letter dated March 30, 1994, you requested a tariff
classification ruling.
The high voltage solid state relays (SSR's) are described in your letter
as monolithic integrated circuits which function as relays. Mr. John
Rosowski, AT&T engineer, explained that the SSR's consist of a photodiode
array, one or two pairs of high voltage MOSFET transistor switches, a JFET
transistor, current limiting circuitry, a resistor, an NPN transistor, four
photodiodes, a PNP transistor, a DMOS transistor and a light emitting diode.
He explained that the SSR's do not have any discrete components. All of the
components are defused onto a semiconductor chip. Mr. Rosowski also stated
that the SSR's are not digital devices.
The applicable subheading for the high voltage solid state relays will be
8542.19.0065, Harmonized Tariff Schedule of the United States (HTSUS), which
provides for "[analog monolithic integrated circuits, other than digital],
free of duty"
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
