**RE:** Air electric drilling and tapping units used as lightweight
drilling machines and tapping units.

Dear Mr. Vroman:

This is in response to your letter on behalf of Cross Huller North
America requesting a ruling regarding the tariff classification under
the Harmonized Tariff Schedule of the United States (HTSUS) of air
electric quill type (drilling and tapping units), universal stands,
mounting bases and hydro checkers. The National Commodity Specialist
Division forwarded your letter to this office for a response.

**FACTS:**

The subject merchandise are air electric quill drilling and tapping
units, universal stands, mounting bases, and hydro checkers. Some of the
units at issue here are described as lightweight drilling machines.
Other of the electric units will be used as tapping units. (A quill is a
metal cylinder that contains and supports the spindle assembly. It moves
up and down, but unlike the spindle, it does not rotate.) These drilling
and tapping units are designed for use in a wide variety of light-duty
operations such as in the automotive, electronics, appliance, aerospace,
wood, plastic and other industries that can benefit from lightweight and
less costly drilling and tapping units. Electric motors drive the
spindles in the drilling and tapping units. The unit cycle is air
actuated, and air cylinders power it. They are designed for mounting on
a stand, or on an end of a robotic arm. The imported units will include
chucks, but no drill bits, taps, or collets.

The manufacturer produces several different drill units described in the
submitted literature as electrically driven, air actuated, hydraulic
feed units. The tap units include electrically driven, air actuated
models and one mechanical ball screw type tapping unit. The latter is
the only drill or tap unit that does not incorporate a hydro checker.
All models have a quill and a drill or tap chuck.

It is intended that the primary use of the universal stands will be as a
piece of equipment for mounting the drilling and tapping units. They are
made of steel and are comprised of a tubular column and a holding
bracket. The mounting bases are steel mounting brackets that allow the
drilling or tapping units to be attached to a stand, robot arm, or the
machine center etc.

The hydro checkers are speed controllers that control the cutting feed
of the drilling and tapping units. They use a spring or compressed air
to retract the rod.

For the drilling and tapping units to be operational, the customer must
supply several pieces of equipment that are not imported with the
product including a compressor, control panel, motor starter, 4-way
valve and air logic.

**ISSUE:**

What is the classification under the HTSUS of the air electric drilling
and tapping units (imported with the universal stands or bases, and
imported without the universal stands or bases), the universal stands,
mounting bases and the hydro checkers.

**LAW AND ANALYSIS:**

Classification under the Harmonized Tariff Schedule of the United States
(HTSUS) is made in accordance with the General Rules of Interpretation
(GRI's). GRI 1 provides that the classification of goods shall be
determined 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, the remaining GRIs may then be
applied.

The Harmonized Commodity Description And Coding System Explanatory Notes
(EN's) constitute the official interpretation of the Harmonized System.
While not legally binding on the contracting parties, and therefore not
dispositive, the EN's provide a commentary on the scope of each heading
of the Harmonized System and are thus useful in ascertaining the
classification of merchandise under the system. Customs believes the
EN's should always be consulted. See T.D. 89‑80, 54 Fed. Reg. 35127,
35128 (Aug. 23, 1989).

The HTSUS provisions under consideration are as follows:

8459. Machine tools (including way-type unit head machines) for
      drilling, boring, milling, threading or tapping by removing metal
      other than lathes (including turning centers) of heading 8458:

> Other drilling machines:

8459.29.00 Other.

8459.70 Other threading or tapping machines:

80. Other.

> \* \* \* \* \* \* \*

8466. Parts and accessories suitable for solely or principally with the
      machines of heading 8456 to 8465, including work or tool

> holders, self-opening dieheads, dividing heads and other special
> attachments for machine tools; tool holders for any type of tool for
> working in the hand:

Other:

8466.93 For machines of headings 8456 to 8461:

Bed, base, table, head, tail, saddle, cradle,

> cross slide, column, arm, saw arm, wheelhead, tailstock, headstock,
> ram, frame, work-arbor support and C-frame castings, weldments or
> fabrications:

Other:

8466.93.53 Other.

\* \* \* \* \* \* \*

For machines of heading 8456 to 8461:

Other:

Other:

8466.93.95 Other.

> \* \* \* \* \* \* \*

8501. Electric motors and generators (excluding generating sets):

> \* \* \* \* \* \* \*

In this case, the drilling and tapping units consist of several
components that are attached to an electric motor. Consequently, it is
necessary to determine whether the drilling units and tapping units
should be classified as electric motors in heading 8501, HTSUS or as
another type of machine. We have previously indicated that a good
consisting of a motor and the actual mechanism or another part of the
mechanism the motor serves to power will be beyond the scope of heading
8501, and will be classified with the machine, apparatus or device with
which it is solely or principally used. See HQ 950834, dated March 6,
1992. However, in HQ 950834, we stated that an electric motor is
classifiable under heading 8501, HTSUS, even when imported with
additional components (other than those listed in EN 85.01) if:

(1) those additional components complement the function of the motor (HQ
    083955, dated July 10, 1989); (2) those additional components are
    devices with which motors are commonly equipped (HQ 087909 dated
    December 26, 1990); (3) those additional components serve merely to
    transmit the power the motors produce (HQ 950557, dated December 26,
    1991).

For example, electric window regulators used to convert standard
automobile windows to power windows, and which consist of a motor,
components to hold and/or move the window, plus mounting brackets for
the entire assembly, were held to be outside the scope of heading 8501,
and were classified in subheading 8708.29.50, HTSUS, as other parts and
accessories of automobile bodies. See HQ 957575, dated July 10, 1995.

We note that the imported drilling and tapping units contain components
such as the tap or drill chucks, the quill and the hydro checker (except
for the ball screw type tap unit). These components do not merely
transmit the power the motors produce. They help perform the work of the
drilling and tapping units and they are not items that electric motors
are commonly equipped with. Therefore, we conclude that the drill or tap
units are not classified as electric motors in heading 8501, HTSUS.

As imported a number of components necessary for the operation of the
completed drilling and tapping are missing from the machines. The items
that are missing from the drilling and tapping units, which the customer
must supply, include a compressor, controls, valves, etc. Consequently,
we must determine whether the drilling and tapping units imported with
the universal stands or the mounting bases, but without several other
components, should be classified as unfinished or incomplete machine
tools of heading 8459, HTSUS.

EN 84.59 states that:

> This heading covers machine-tools for drilling, boring, milling,
> threading or tapping by removing metal, **other than** lathes
> (including turning centres) of **heading 84.58.**
>
> In general machine tools are power-driven but similar machines, worked
> by hand or pedal, are also covered by this heading. These latter types
> can be distinguished from the hand tools of **heading 82.05** and from
> the tools for working in the hand of **heading 84.67,** by the fact
> that they are usually designed to be mounted on the floor, on a bench,
> on a wall or on another machine, and are thus usually provided with a
> base plate, mounting frame, stand, etc.

This heading covers :

> \(1\) **Drilling machines.** These are used for cutting cylindrical
> holes, including recessed holes, in articles by means of a rotating
> tool called a drill or bit. The article remains immobile during the
> working of the tool which is rotated (cutting action) or fed into the
> work (feed action). This heading also covers drilling machines which

> both processes.

...

> \(4\) **Tapping machines** (i.e., machines to produce a screw thread
> in an existing hole) and **threading machines** for threading bolts,
> screws, etc. It should be noted that **thread milling machines** are
> regarded as milling machines.

...

> **Subject** to the general provisions regarding the classification of

> machine tools of this heading are classified in **heading 84.66.**

GRI 2(a) governs the classification of incomplete articles. It provides
that goods imported in an incomplete condition are to be classified as
the finished article. GRI 2(a) states that:

> > Any 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.
>
> The EN for Rule 2(a) explains that:
>
> \(I\) The first part of Rule 2(a) extends the scope of any heading
> which refers to a particular article to cover not only the complete
> article but also that article incomplete or unfinished, **provided**
> that, as presented, it has the essential character of the complete or
> finished article.

In interpreting the HTSUS, we have construed the term \"essential
character\" to mean the attribute which strongly marks or serves to
distinguish what an article is; that which is indispensable to the
structure, core or condition of the article. See HQ 956538 dated
November 29, 1994. Factors found to be relevant in other contexts are
the significance of the imported components or their role in relation to
the use or overall functioning of the completed article and, to the
extent that it validates that comparison, the cost or value of the
completed article versus the cost or value of the imported merchandise.
See HQ 956410 dated October 14, 1994. Accordingly, we need to determine
whether under GRI 2(a) the drilling and tapping units imported with
stands or bases would be considered as an unfinished machine tools for
drilling or tapping classified in heading 8459, HTSUS.

In HQ 966681 dated November 25, 2003, we considered whether a saw blade
and an electric motor without a base or frame for mounting should be
classified as a machine tool for sawing stone in heading 8464, HTSUS. We
explained that EN 84.64 indicated that the drafters of the heading 8464,
HTSUS expected that a tool classified as a machine tool in heading 8464,
would have a base plate, frame etc., so that it could be mounted or
placed on a bench, table, floor etc. Based on the language of EN 84.64,
we determined that something that demonstrates the tool is intended for
mounting onto something else is what normally identifies a tool as a
machine tool classified in heading 8464, HTSUS. Therefore, we ruled that
without the base or another component for mounting, the motor and the
saw blade lack a necessary element for classification as an unfinished
machine tool of heading 8464.

We note that EN 84.59 contains the identical language of EN 84.64
regarding machine tools. Both EN 84.59 and EN 84.64 indicate that
articles that are classified in those headings are usually designed to
be mounted on the floor, on a bench, on a wall or on another machine,
and are thus usually provided with a base plate, mounting frame, stand,
etc. Therefore, the analysis used in HQ 966681, regarding machine tools
that are classified in the heading being usually being designed to be
mounted on the floor, on a bench on a wall or on another machine would
apply to articles considered for classification in heading 8459, HTSUS.
In this instance, most of drilling and tapping units will be imported
with a universal stand or a mounting base, and thus they satisfy a
prerequisite for being classified as a machine tool in heading 8459,
HTSUS.

Although as imported the drilling and tapping units lack a number of
components that are necessary for the operation of the machines, a
number of key components such as the motor, the chuck, mechanical ball
screw, and the hydro checker are included in the unfinished drilling and
tapping units. We believe that the presence of these components is
enough to indicate that the basic structure and essence of the finished
drilling and tapping units are contained in the articles to be imported.
In other words, we believe that unfinished drilling and tapping units
imported with the universal stands or bases will have the basic identity
of machine tools for drilling or tapping. Accordingly, we find that the
subject drilling and tapping units that are imported with universal
stands or mounting bases have the essential character of complete
drilling and tapping units. Therefore, under GRI 2(a) the unfinished
units that are used for drilling are classified in subheading
8459.29.00, HTSUS, as other drilling machines. Similarly, unfinished
units that are used for tapping are classified in 8459.70.80, HTSUS as
other threading or tapping machines: other.

Consistent with the analysis above, EN 84.59 indicates that the drilling
and tapping units without a stand or base lack an essential element of a
machine tool, something that demonstrates that the machines are designed
to be mounted on the floor, on a bench on a wall or on another machine.
Therefore, because they do not have a means for mounting, the drilling
and tapping units imported without stands or bases cannot be classified
as unfinished machine tools for drilling or tapping in heading 8459,
HTSUS.

EN 84.59 indicates that subject to the general provisions regarding the
classification of parts (see the General Explanatory Note to Section
XVI), parts and accessories of the machine tools of heading 8459, HTSUS
are classified in heading 8466, HTSUS**.** Consequently, we must
determine if the drilling and tapping units imported without a stand or
base stand are classified in heading 8466, HTSUS, as parts or
accessories suitable for use solely or principally with the machines of
headings 8456 to 8465.

> Noting that Chapter 84, HTSUS is in within Section XVI of the HTSUS,
> Note 2 for Section XVI would be applicable. Section XVI, Note 2,
> HTSUS, states:
>
> Subject to note 1 to this section, note 1 to chapter 84 and to note 1
> to chapter 85, parts of machines (not being parts of the articles of
> heading 8484, 8544, 8545, 8546 or 8547) are to be classified according
> to the following rules:\
> \
> (a) Parts which are goods included in any of the headings of chapters
> 84 and 85 (other than headings 8409, 8431, 8448, 8466, 8473, 8485,
> 8503, 8522, 8529, 8538 and 8548) are in all cases to be classified in
> their respective headings;\
> (b) Other parts, if suitable for use solely or principally with a

> 8448, 8466, 8473, 8503, 8522, 8529 or 8538 as appropriate. However,

Customs generally will consider an article to be a part if: it is
combined with other articles to be used; or it is an integral,
constituent or component part, without which the article to which it is
joined could not function; or it aids in the safe and efficient
operation of the main article; or it is identifiable by shape or other
characteristics as an article solely or principally used as a part. See
HQ 966441, date June 12, 2003. In this instance, we believe that the
drilling and tapping units imported without stands or bases meet the
criteria for being considered a part of complete drilling and tapping
units. Therefore, they are classified in subheading 8466.93.95, HTSUS.

The stands and the bases imported separately from the drilling and
tapping units also qualify as parts in accordance with criteria
mentioned above. Therefore, they also would be classified in heading
8466, HTSUS. We believe that they are most appropriately described in
subheading 8466.93.53, HTSUS.

The last items that we must consider are the hydro checkers imported
separately from drilling and tapping units. The hydro checkers are speed
controllers that control the cutting feed of the drilling and tapping
units. They

use a spring or compressed air to retract the rod. A hydro checker can
be

described as a self-contained oil mechanism with an adjustable knob that
controls the opening of an orifice. In accordance with Section XVI, Note
2(b), the hydro checkers are classified in subheading 8466.93.95, HTSUS.

**HOLDING:**

The drilling units imported with the stands or the bases are classified
in subheading 8459.29.00, HTSUS, as: "Machine tools ... for drilling,
boring, milling, threading or tapping by removing metal...: Other
drilling machines: Other." The units that are used for tapping that are
imported with the stands or the bases are classified in subheading
8459.70.80 as: "Machine tools (including way-type unit head machines)
for drilling, boring, milling, threading or tapping by removing metal
other than lathes...: Other threading or tapping machines: Other."

The stands and bases imported separately from the drilling and tapping
units are classified in subheading 8466.93.53, HTSUS, which provides for
"Parts and accessories suitable for use solely or principally with the
machines of heading 8456 to 8465, including work or tool holders,
self-opening dieheads, dividing heads and other special attachments for
machine tools...: Other: For machines of heading of 8456 to 8461: Bed,
base, table head tail saddle, cradle, cross slide, column, arm, saw,
arm, wheelhead, tailstock, headstock ram, frame, work-arbor support, and
C-frame castings, weldments or fabrications: Other: Other."

The drilling and tapping units that are imported without a stand or a
base and the hydro checkers imported separately are classified in
subheading 8466.93.95, HTSUS as: "Parts and accessories suitable for use
solely or principally with the machines of headings 8456 to 8465...:
Other: For machines of heading 8456 to 8461...: Other: Other: Other."
