RE: The tariff classification of integral drive generators from Singapore

Dear Mr. Burke:

In your letter dated June 26, 1989 you requested a tariff classification ruling.

The submitted literature describes the integrated drive generator (IDG) as a device that combines a Sundstrand gear differential CSD with an advanced design spray-oil cooled generator. The IDG is composed of two components. One-half of the combined unit is the CSD which is an automatic variable speed changer. The other half is an oil cooled generator. The purpose of the combined unit is to create a generator that has a constant voltage output. This is accomplished by the CSD portion of the IDG constantly varying the gear ratio from the jet engine to the generator to provide a constant drive speed to the generator. The IDG appears to have an AC output of less than 75KVA.

The applicable subheading for the integral drive generator will be 8501.61.0000, Harmonized Tariff Schedule of the United States (HTS), which provides for "AC generators, [o]f an output not exceeding 75KVA." The rate of duty will be 3 percent ad valorem.

Articles classifiable under subheading 8501.61.0000, HTS, and which are the products of Singapore, and which are 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.
