**RE:** Protest 4101-00-100050; robotic pump (Microlab ATplus 2)

Dear Port Director:

This is our decision on Protest 4101-00-100050, timely filed on behalf
of Hamilton Company (Protestant) on January 26, 2000, against your
classification decision regarding merchandise described as a robotic
pump, an automated liquid sample processor machine, under the Harmonized
Tariff Schedule of the United States (HTSUS). The entry dated December
18, 1999, was liquidated January 3, 2000.

**FACTS:**

The merchandise is described as Microlab ATplus 2 (ML-AT+2), a robotic
pump that is an automated liquid sample processor machine. The robotic
pump is used in clinical and research laboratories to prepare liquid
samples for subsequent analysis. Literature submitted with the protest
indicates that it consists of a pipetting station, a washing/wiping
station, a liquid level detector, and optional barcode scanner.

The pipetting station is designed to rapidly transfer precise amounts of
liquid samples from test tubes to microtiter plates, microtubes, or
similar containers. It utilizes disposable pipette tips to prevent
contamination. Alternatively, the built-in wash/wipe station provides
tip washing and wiping between single pipetting steps. Sensors in the
primary and reagent racks enable precise distribution and mixing of
reagents with samples, as well as serial dilution. The optional barcode
scanner ensures positive sample identification.

While not stated specifically, it is presumed that the Microlab ATplus 2
incorporates a liquid pump that assists in the transfer of the liquids.

Protestant claims classification of the Microlab ATplus 2, robotic pump,
under subheading 8413.19.00, HTSUS, which provides for: Pumps for
liquids, whether or not fitted with a measuring device; liquid
elevators; parts thereof: Pumps fitted or designed to be fitted with a
measuring device: Other.

At liquidation, Customs classified the merchandise under subheading
8479.89.97, HTSUS, which provides for: Machines and mechanical
appliances having individual functions, not specified or included
elsewhere in this chapter; parts thereof: Other machines and mechanical
appliances: Other: Other: Other.

**ISSUE:**

Whether the Microlab ATplus 2, robotic pump, is classified as a pump for
liquids under heading 8413, HTSUS, or as a machine, whose principal
purpose is not described in any heading of chapter 84, and is therefore
classified under heading 8479, HTSUS.

**LAW & ANALYSIS:**

The General Rules of Interpretation (GRIs) taken in their appropriate
order provide a framework for classification of merchandise under the
HTSUS. The majority of imported goods are classified by application of
GRI 1; that is, according to the terms of the headings of the tariff
schedule and any relative section or chapter notes. In the event that
the goods cannot be classified solely on the basis of GRI 1, and if the
headings and legal notes do not otherwise require, then the remaining
GRIs may be applied.

The Explanatory Notes (ENs) to the Harmonized Commodity Description and
Coding System constitute the official interpretation of the Harmonized
System at the international level. Though not dispositive, the ENs
provide a commentary on the scope of each heading of the HTSUS. Customs
believes the ENs should always be consulted. See T.D. 89-80, 54 Fed.
Reg. 35127-28 (Aug. 23, 1989).

The merchandise under protest is described as a robotic pump which
functions as an automated liquid sample processor machine.

The following headings and legal notes are relevant to the
classification of the Microlab ATplus 2, robotic pump:

> 8413, HTSUS, which provides for: Pumps for liquids, whether or not
> fitted with a measuring device; liquid elevators; parts thereof.
>
> 8479, HTSUS, which provides for: Machines and mechanical appliances
> having individual functions, not specified or included elsewhere in
> this chapter; parts thereof.
>
> Section XVI, Note 3 states: Unless the context otherwise requires,
> composite machines consisting of two or more machines fitted together
> to form a whole and other machines adapted for the purpose of
> performing two or more complementary or alternative functions are to
> be classified as if consisting only of that component or as being that
> machine which performs the principal function.
>
> Chapter 84, Note 7 states: A machine which is used for more than one
> purpose is, for the purposes of classification, to be treated as if
> its principal purpose were its sole purpose. ... \[A\] machine the
> principal purpose of which is not described in any heading or for
> which no one purpose is the principal purpose is, unless the context
> otherwise requires, to be classified in heading 8479.

We must first determine whether the robotic pump is a pump for liquids
under heading 8413, HTSUS. This heading covers most machines and
appliances for raising or otherwise continuously displacing volumes of
liquids. This heading also includes delivery pumps equipped with
measuring or price-calculating mechanisms such as are used for supplying
petrol or oil in garages, and pumps specially designed for use with
other machines. See EN 84.13.

Based on the information provided, the Microlab ATplus 2 is designed to
batch transfer samples from tubes to microtiter plates, microtubes, or
similar containers by means of precision disposable pipette tips. While
Microlab ATplus 2 may be a machine containing a specialized pump,
presumably used to charge and discharge liquid from the pipette tips, it
is not in and of itself a pump. It appears that the principal function
performed by Microlab ATplus 2 is the rapid transfer of precise amounts
of liquids through the use of pipettes. This transfer of samples does
not involve the continuous displacement of volumes of liquid, but rather
the distribution of discrete volumes of liquid among multiple
containers. Further, it is the physical movement of the pipette tips
from one container to another, not the pump mechanism, which actually
effects the transfer of the samples. Therefore, the Microlab ATplus 2
may not be classified as a pump for liquids under heading 8413, HTSUS,
as the protestant claims.

As described, the Microlab ATplus 2 performs several complementary
functions: pipetting, mixing, diluting, washing, etc. It is a composite
machine the primary function of which is the pipetting function that
allows the transfer and distribution of discrete volumes of liquid among
multiple containers. According to Section XVI, Note 3, the Microlab
ATplus 2 must be classified as if consisting only of that component, or
as being that machine, which performs the principal function. Mechanical
pipettes, without pumps, similar to the pipetting function of Microlab
ATplus 2 were classified under subheading 8479.89, HTSUS. See HQs 957301
and 957302 dated January 18, 1995, which classified mechanical pipettes
as machines and mechanical appliances having individual functions, not
specified or included elsewhere in chapter 84 under subheading
8479.89.90 (now 8479.89.97), HTSUS.

There is no HTSUS heading that specifically describes a machine or
appliance that processes liquid samples, the principal purpose of the
Microlab ATplus 2. According to chapter 84, note 7, Microlab ATplus 2, a
machine the principal purpose of which is not described in any heading,
is therefore classified under heading 8479, HTSUS. Similarly, machines
for preparing air samples were determined to be classifiable under
subheading 8479.89.90 (now 8479.89.97), HTSUS, in HQs 087597 and 088242
dated November 27, 1990.

Microlab ATplus 2, an automated liquid sample processor, is not itself a
pump, but a composite machine that must be classified according to its
principal function. Since the principal function of Microlab ATplus 2 is
not described in any heading of chapter 84, in accordance with prior
Headquarters rulings, it is classified under subheading 8479.89.97,
HTSUS, which provides for: Machines and mechanical appliances having
individual functions, not specified or included elsewhere in this
chapter; parts thereof: Other machines and mechanical appliances: Other:
Other: Other.
