RE: The tariff classification of module board assemblies for an
aircraft engine thrust management system from Mexico
Dear Mr. Merber:
In your letter dated May 15, 1992 you requested a tariff
classification ruling.
The items involved in this request are several module board
assemblies which comprise the main components of an engine thrust
management system (TMS) for use on turbofan aircraft engines.
The TMS monitors engine thrust, aircraft speed, air temperature
and altitude through data input from several external sensors.
It then compares this data to pre-programmed engine thrust
parameters and determines the optimum engine thrust rating for
the flight mode selected (i.e. - takeoff, cruise, etc). The
system can be operated by the pilot in manual mode, utilizing the
thrust readings displayed on the cockpit display panel, or in
automatic mode, with the system regulating the thrust.
Physically, the TMS consists of eight modules. Seven of the
eight are mounted together in a steel container that is
physically incorporated into the jet aircraft at a location
remote from the pilot's control panel. The remaining module is a
thrust rating panel that is mounted on the pilot's control panel.
The module boards involved herein consist of the following: 1)
CPU/timing module; 2) memory module; 3) ARINC 429 DITS and DITS
expansion module; 4) analog input/output module; 5) system
interface module; 6) thrust display panel.
The applicable subheading for the above listed six modules
of the Thrust Management System will be 9032.90.6080, Harmonized
Tariff Schedule of the United States (HTS), which provides for
other parts of automatic regulating or controlling instruments
and apparatus, other. The duty rate will be 4.9 percent ad
valorem.
Articles classifiable under subheading 9032.90.6080, HTS,
which are products of Mexico are entitled to duty free treatment
under the Generalized System of Preferences (GSP) upon compliance
with all applicable regulations.
Articles classifiable under subheading 9032.90.6080, HTS,
and are the products of Mexico, and certified for use in civil
aircraft in accordance with General Note 3(c)(iv), HTS, are
entitled to duty free treatment under the Agreement on Trade in
Civil Aircraft upon compliance with all applicable regulations.
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
