RE: The tariff classification of a mixer (hybrid integrated
circuit) from the Philippines
Dear Ms: Patrick
In your letter June 5, 1992, you requested a tariff
classification ruling.
Your letter describes the mixer, identified as WJ-M2E, as a
microcircuit assembly consisting of active and passive components
mounted on a ceramic substrate. The submitted literature
indicates that thin film technology is used in the assembly
process and you have advised us that the components cannot be
easily removed and replaced under ordinary manufacturing
conditions.
The applicable subheading for the mixers will be
8542.20.0080, Harmonized Tariff Schedule of the United States
(HTS), which provides for "[h]ybrid integrated circuits," 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
