NY 874448 May 19, 1992 CLA-2-84:S:N:N1:110 874448 CATEGORY: Classification TARIFF NO.: 8473.30.4000 Mr. Dennis Heck Castelazo & Associates 5420 West 104th Street Los Angeles, CA 90045 RE: The tariff classification of a Bravo Processor Board from Hong Kong Dear Mr. Heck: In your letter dated May 11, 1992, on behalf of AST Research, Inc., you requested a tariff classification ruling. The merchandise under consideration involves a processor board that is designed for use with a Bravo 386SX/20 desktop computer. The board contains a 386SX microprocessor, math coprocessor socket, one programmable array logic IC (PAL), and several capacitors and resistors. This board is designed to be used in conjunction with, and mated to the Bravo 386SX/20 system board (motherboard). The main function of this processor board is to perform the arithmetical computations of the processing unit. The motherboard, with which it is mated, contains the ROM BIOS, the system RAM memory and control, keyboard interface and control, video interface and control, disk drive interface and control, and serial/parallel port control (I/O capabiility). The main functions of the system board (motherboard) are to store the processing program (system memory) and to allow the system to be freely programmed by the users utilizing the resident AST BIOS, the I/O bus and keyboard controller. If these two boards are imported together, they would meet the definition of a digital processing machine as defined in Legal Note 5 (A) to Chapter 84 of HTS. The processor board is in this situation separately imported, and without the system memory, ROM BIOS, and keyboard controller, would not meet the definition of a digital processing machine. The applicable subheading for the Bravo Processor Board will be 8473.30.4000, Harmonized Tariff Schedule of the United States (HTS), which provides for parts and accessories of the machines of heading 8471 not incorporating a cathode ray tube. The rate of duty will be free. 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 Area Director New York Seaport
