RE: Notebook ADP Machine Subassemblies; BIOS ROM; Chapter 84,
Note 5(A)(a); GRI 2(a); HQs 950672, 950221, and 951443;
NYs 851540, 874448, and 869571
Dear Ms. Cortes:
This is in response to your letter of December 14, 1994, concerning the classification of
notebook automatic data processing (ADP) machine subassemblies under the Harmonized Tariff
Schedule of the United States (HTSUS).
FACTS:
The merchandise consists of two configurations of notebook ADP machine subassemblies with
liquid crystal display (LCD). The first configuration is comprised of the notebook ADP machine
without the BIOS ROM chip. The second configuration is comprised of the notebook ADP
machine without the ROM BIOS chip, hard drive unit, and floppy drive unit.
The subheading under consideration is as follows:
8473.30.50: [p]arts and accessories . . . suitable for use
solely or principally with machines of headings
8469 to 8472: [p]arts and accessories of the
machines of heading 8471: [n]ot incorporating a cathode ray tube: [o]ther:
[o]ther.
Goods classifiable under this provision receive duty-
free treatment.
ISSUE:
Whether the two configurations of notebook ADP machine subassemblies impart the essential
character of finished ADP machines, or are classifiable under subheading 8473.30.50, HTSUS, as
parts of heading 8471, HTSUS, not incorporating a cathode ray tube.
LAW AND ANALYSIS:
Classification of merchandise under the HTSUS is in accordance with the General Rules of
Interpretation (GRI's).
GRI 1 provides that classification is determined according to the terms of the headings and any
relative section or chapter notes.
The definitions for "motherboard" and "BIOS ROM" can be found in The Computer Glossary,
Fourth Edition. The term "motherboard" is defined as:
the main printed circuit board in an electronic device which
contains sockets that accept additional printed circuit
boards. In a personal computer, the motherboard contains the bus, the microprocessor
and all the chips used for
controlling the peripherals that are considered standard
with the system, such as the keyboard, text and graphics display, serial and parallel ports
and joystick and mouse
interfaces.
The term "BIOS ROM" is defined as:
the part of an operating system that contains the machine
instructions necessary to activate the peripheral devices.
The ROM indicates that it is permanently stored in a read only memory chip.
By definition, then, the motherboard, which is part of both subassembly configurations
described herein, contains all the devices necessary for controlling the peripherals with the system.
The BIOS is responsible for activating the peripheral devices. Therefore, the BIOS is essential to
the operation of the motherboard.
Chapter 84, note 5(A)(a), HTSUS, states that:
(A) For purposes of heading 8471, the expression "automatic
data processing machines" means:
(a) Digital machines, capable of (1) storing the processing
program or programs and at least the data immediately
necessary for execution of the program; (2) being freely
programmed in accordance with the requirements of the
user; (3) performing arithmetical computations specified
by the user; and, (4) executing, without human
intervention, a processing program which requires them to modify their execution,
by logical decision during the processing run.
In HQ 950672, dated February 20, 1992, a CPU motherboard with an 80286 microprocessor,
two 64k EPROMS, and a direct memory access controller was classified as a finished digital
processing unit under heading 8471, HTSUS. In the ruling, it was stated that "[t]he subject CPU
board satisfies this description [note 5(A)(a), chapter 84, HTSUS] of an ADP machine. The
80286 microprocessor and EPROMS enable the board to perform these functions."
Unlike the motherboard in HQ 950672, the subject subassemblies do not contain the BIOS
ROM chip. Therefore they cannot perform the functions described in note 5(A)(a), chapter 84,
HTSUS. The lack of the BIOS ROM chip prevents the motherboard within the subassemblies
from performing input/output functions with the keyboard. Logic and control functions cannot be
performed. Also, the processing program cannot be executed without human intervention.
GRI 2(a) provides that:
[a]ny reference in a heading to an article shall be taken to
include a reference to that article incomplete or unfinished, provided that, as
entered, the incomplete or unfinished article has the essential character of the
complete or finished article. It shall also include a
reference to that article complete or finished (or falling
to be classified as complete or finished by virtue of this
rule) entered unassembled or disassembled.
In HQ 950221, dated November 22, 1991, it was held that a motherboard, imported without a
CPU unit, did not have the essential character of a finished ADP processing unit. Consequently,
under GRI 2(a), because the subject subassembly configurations do not possess the BIOS ROM
chip, essential to their operation, they do not impart the essential character of finished ADP units.
See HQ 951443, dated April 13, 1992; NY 851540, dated April 23, 1990; NY 874448, dated
May 19, 1992; and NY 869571, dated December 12, 1991.
In their imported state as subassemblies, the configurations do not impart the essential
character of any of their constituent components. Because the merchandise is imported in
subassembly form, it is our position that individual components cannot be imported separately,
and an entire subassembly cannot be classifiable under a provision describing an individual
component. Because the subassemblies are necessary to the completion of an ADP system, as
integral, constituent, and component parts, they are classifiable as such.
HOLDING:
The two configurations of notebook ADP machine subassemblies are classifiable under
subheading 8473.30.50, HTSUS, as parts of heading 8471, HTSUS, not incorporating a cathode
ray tube.
Sincerely,
John Durant, Director
