RE: The tariff classification of mercury-cadmium-telluride
wafers from France
Dear Hofheimer:
In your letter dated January 23, 1989 you requested a tariff
classification ruling.
Your letter describes the subject merchandise as single-
crystal and poly-crystal, mercury-cadmium-telluride wafers which
are doped for use in electronics. The wafers are not extensively
worked by a process of selective diffusion or a similar process.
The applicable subheading for the mercury-cadmium-telluride
semiconductor wafers will be 3818.00.0000, Harmonized Tariff Schedule
of the United States (HTS), which provides for "Chemical compounds
doped for use in electronics," 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
