**RE**: Protest No. 3901-02-101793; Steel Pipe Fittings; Insulated Steel
Pipe Fittings;

19 U.S.C. 1625(c)(1); Delayed effective date

Dear Port Director:

This is our decision on Protest No. 3901-02-101793 filed by KMZ Rosenman
on behalf of EMCO Electronics International (EMCO or protestant),
against your decision regarding the classification, under the Harmonized
Tariff Schedule of the United States Annotated (HTSUSA), of certain
steel pipe fittings. Consideration was given to supplemental arguments
and information submitted by the protestant, which was received July 10,
2003.

**FACTS**:

The merchandise under protest consists of certain steel fittings for
electrical conduits imported by EMCO and produced in China and India.
These fittings are used to connect electrical conduit pipe together or
to connect conduit pipe to a junction box. These goods operate/connect
by either a set screw mechanism or by compression fitting. The set screw
connectors and set screw couplings are fitted with fastening devices
such as a Tri-combo, Phillips, or slotted screw or hex bolt. The
compression connectors and compression couplings have gland rings or
spacers and a compression-type lock nut. These screws, bolts, and nuts
come in various sizes, according to the size of the coupling or
connector. The protestant claims some of the instant fittings are lined
internally with a plastic insulating material.

The protestant advocates classification of the unlined articles in
subheading 7326.90.85, HTSUS, which provides for "Other articles of iron
or steel: Other: Other: Other: Other." It also contends that
classification for the insulated articles is under subheading
8547.90.00, HTSUS, as "Insulating fittings for electrical machines,
appliances or equipment, being fittings wholly of insulating material
apart from any minor components of metal (for example, threaded sockets)
incorporated during molding solely for the purposes of assembly, other
than insulators of heading 8546; electrical conduit tubing and joints
therefor, of base metal lined with insulating material: Other."

The subject entries were liquidated on July 19, 2002. The protest was
filed on October 2, 2002.

**ISSUES**:

Whether the instant steel connectors and couplings are classified under
heading 7307, HTSUSA, as tube or pipe fittings; heading 7326, HTSUSA, as
other articles of iron or steel; or heading 8547, HTSUSA, as insulated
electrical conduit tubing or joints.

Whether HQ 966958, which revoked NY I81109, affects the subject entries.

**LAW AND ANALYSIS**:

[Classification Issues]{.underline}:

Classification under the HTSUSA is made in accordance with the General
Rules of Interpretation (GRIs). 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
(ENs) constitute the official interpretation of the Harmonized System at
the international level. While not legally binding, the ENs provide a
commentary on the scope of each heading of the HTSUSA and are thus
useful in ascertaining the classification of merchandise under the
System. The Bureau of Customs and Border Protection (Customs) believes
the ENs should always be consulted. *See* T.D. 89-90, 54 Fed. Reg.
35127, 35128 (August 23, 1989).

The HTSUSA provisions (2002) under consideration are as follows:

7307. Tube or pipe fittings (for example, couplings, elbows, sleeves) of
      iron or steel:

EN 73.07 provides in pertinent part as follows:

> This heading covers fittings of iron or steel, mainly used for
> connecting the bores of two tubes together, or for connecting a tube
> to some other apparatus, or for closing the tube aperture. This
> heading **does not** however **cover** articles used for installing

> the tubes and pipes on walls, clamping or tightening bands or collars
> (hose clips) used for clamping flexible tubing or hose to rigid
> piping, taps, connecting pieces, etc.) (heading **73.25** or
> **73.26**)\[emphasis in original\].
>
> The connection is obtained:

In support of its position, the protestant cites New York Ruling Letter
(NY) I81109, dated April 26, 2002, where, the protestant contends,
Customs issued a ruling for the same products as the instant products,
produced by the same manufacturer, and imported by another importer, and
which were classified under subheading 7326.90.8586, HTSUSA.
Additionally, the protestant claims that some of the couplings that are
insulated with plastic are classified in subheading 8547.90.00, HTSUS.
Classification in heading 7307, HTSUSA has also been considered. Because
heading 7326 covers all articles of iron or steel not elsewhere
specified or included (see EN 73.26), the goods will be provided for in
heading 7326 only if they are described in that heading and if they are
not provided for in heading 7307 or heading 8547.

Documentation in the file, including illustrations, indicates that the
couplings serve to connect the bores of two tubes, usually electrical
conduits, together. They have indentations in the center or stops to
center the bores of the tubes in the coupling. Connectors attach a tube
to some other apparatus (*i.e*., a junction box). One end secures the
tube, as the coupling does, by threading or compression set screw; the
other end slides into the apparatus and is usually tightened with a lock
nut or other fastener. We find that the instant articles without
insulating material are within the scope of the description provided in
EN 73.07, above. Accordingly, we find that the instant articles without
insulating material are provided for in heading 7307, HTSUSA.

It is unclear from the documents in the file whether or not all of the
instant articles are threaded. We find that the unlined, threaded
couplings and connectors are classified under subheading 7307.92.3010,
HTSUSA, as: "Tube or pipe fittings (for example, couplings, elbows,
sleeves) of iron or steel: Other: Threaded elbows, bends and sleeves:
Sleeves (couplings): Of iron or nonalloy steel." We find that the
unlined, unthreaded couplings and connectors are classified under
subheading 7307.99.5045, HTSUSA, as: "Tube or pipe fittings (for
example, couplings, elbows, sleeves), of iron or steel: Other: Other:
Other: Of iron or nonalloy steel: Other." EN 73.07 also states in
relevant part that the heading excludes "Bolts, nuts, screws, etc.
suitable for use in the assembly of tube or pipe fittings (**heading
73.18**)," which would include the above-mentioned screws, lock nuts and
other fasteners.

The information in the file indicates that screws and bolts of various
sizes and types were imported in the entries under protest. The threaded
bolts used on the fittings are classified under subheading 7318.15.20,
HTSUS, with further delineation depending on the diameter and type. The
threaded screws used to connect the fittings to the pipes are classified
either under subheading 7318.15.60, HTSUS, or subheading 7318.15.80,
HTSUS, with further delineation depending on the diameter and type.

[Heading 7326]{.underline}

Based upon our determination that the pipe fittings without insulating
material are classified under heading 7307, HTSUSA, they are not
described or classified in subheading 7326.90.8586, HTSUSA. Upon further
review of the information submitted and the classification in NY I81109,
we concluded that the classification of the articles in I81109 was
incorrect. That ruling was revoked by HQ 966958, dated April 20, 2004.
*See* CUSTOMS BULLETIN of May 4, 2004, vol. 38, no. 19 (containing HQ
966958).

[Heading 8547]{.underline}

Electrical conduits coated or lined with insulating material such as
special electrically insulating varnish, paper or paperboard, rubber,
plastics, etc. are classified under heading 8547, HTSUSA. EN 85.47
states in relevant part:

\(B\) ELECTRICAL CONDUIT TUBING AND JOINTS THEREFOR, OF BASE METAL LINED
WITH INSULATING MATERIAL

This group covers the metal tubing used in permanent electrical
installations (e.g., house wiring) as insulation and protection for the
wires, provided it has an interior lining of insulating material.
Uninsulated metal tubing, often used for the same purpose, is excluded
(Section XV).

The tubing of this group consists of spiralled metal strip wound on to
an interior tube of insulating material, or of rigid metal tubing
(usually iron or steel) coated or lined with insulating material. The
insulating material may be special electrically insulating varnish,
paper or paperboard, rubber, plastics, etc. Metal tubing simply coated
with varnish to prevent corrosion is excluded (Section XV).

This group also covers joints used for connecting tubing of this heading
provided they are also of base metal and coated or lined with insulating
material (e.g., straight joints, elbows, tee joints and cross-overs).

Uninsulated steel joints are not covered under this heading, and are
classified under heading 7307, HTSUSA. In fact, the EN to heading 7307
states that this heading excludes, "(f) Insulated joints for electrical
conduit tubing (heading 85.47).\" Certain of the entries contain
fittings that are coated or plated with plastic insulating material.
Those couplings fall under heading 8547, HTSUSA. *See* NY I84073, dated
August 22, 2002.

[19 U.S.C. 1625 Issue]{.underline}:

The basic chronology at issue is as follows. The subject entries were
filed between March 25, 2002 and July 4, 2002; the goods were entered
under subheading 7307.92.3010, HTSUSA. On April 26, 2002, the National
Commodity Specialist Division issued NY I81109, which classified similar
if not identical couplings and connectors in subheading 7326.90.8586,
HTSUSA. On July 19, 2002, the Port of Chicago liquidated the entries
under subheading 7307.92.3010, HTSUSA. Based on classification under
subheading 7307.92.30, the port also imposed additional duties on the
pipe fittings under subheading 9903.73.93, HTSUSA, in accordance with
the Section 201 Relief for Certain Steel Products, the subject of
Presidential Proclamation 7529, issued on March 5, 2002. On October 2,
2002, the protestant sought to protest the liquidation and assessment of
additional duties, citing NY I81109 as justification. On April 21, 2004,
Customs issued HQ 966958, which revoked NY I81109 and classified similar
couplings and connectors in subheading 7307.99.5045, HTSUSA. HQ 966958
was published in the CUSTOMS BULLETIN on May 5, 2004 (vol. 38, no. 19),
and was stated to be effective for merchandise entered or withdrawn from
warehouse for consumption on or after July 3, 2004.

19 U.S.C. 1625(c)(1) provides as follows:

**(c) Modification and revocation**

A proposed interpretive ruling or decision which would-

> \(1\) modify (other than to correct a clerical error) or revoke a
> prior interpretive ruling or decision which has been in effect for at
> least 60 days; or
>
> \(2\) have the effect of modifying the treatment previously accorded
> by the Customs Service to substantially identical transactions;
>
> shall be published in the Customs Bulletin. The Secretary shall give
> interested parties an opportunity to submit, during not less than the
> 30-day period after the date of such publication, comments on the
> correctness of the proposed ruling or decision. After consideration of
> any comments received, the Secretary shall publish a final ruling or
> decision in the Customs Bulletin within 30 days after the closing of
> the comment period. The final ruling or
>
> decision shall become effective 60 days after the date of its
> publication.

19 CFR 177.12(e)(2) provides in pertinent part as follows:

**177.12 Modification or revocation of interpretive rulings \...**

\(e\) *Effective date and application to transactions* --

. . .

> \(2\) *Rulings or decisions in effect for 60 or more days.* If an
> interpretive ruling or holding or principle covered by a protest
> review decision that is modified or revoked under this section had
> been in effect for 60 or more calendar days, the modifying or revoking
> notice will, provided that liquidation of the entry in question has
> not become final, apply to merchandise entered, or withdrawn from
> warehouse for consumption:
>
> \(i\) Sixty calendar days after the date of publication of the final
> modifying or revoking notice in the *Customs Bulletin* under paragraph
> (b)(2) of this section; . . .

19 CFR 177.9(a) provides in pertinent part as follows:

**177.9 Effect of ruling letters.**

> \(a\) *Effect of ruling letters generally.* . . . Generally, a ruling
> letter is effective on the date it is issued and may be applied to all
> entries which are unliquidated, or other transactions with respect to
> which the Customs Service has not taken final action on that date. . .
> .

As indicated above, the entries which are the subject of this protest
were filed between March 25, 2002 and July 4, 2002. HQ 966958 is
effective for merchandise entered or withdrawn from warehouse for
consumption on or after July 3, 2004.

We therefore find that HQ 966958 is not effective with respect to the
subject entries. Additionally, we find that 19 CFR 177.9(a) is support
for the proposition that NY I81109 controls with respect to the entries
at issue. Any Steel 201 duties assessed should be refunded.

**HOLDINGS**:

At GRI 1, the instant steel fittings not lined with a plastic insulating
material fall under heading 7307, HTSUSA. The unlined, threaded
couplings and connectors are classified under subheading 7307.92.3010,
HTSUSA, as: "Tube or pipe fittings (for example, couplings, elbows,
sleeves) of iron or steel: Other: Threaded elbows, bends and sleeves:
Sleeves (couplings): Of iron or nonalloy steel."

The unlined, unthreaded couplings and connectors are classified under
subheading 7307.99.5045, HTSUSA, as: "Tube or pipe fittings (for
example, couplings, elbows, sleeves), of iron or steel: Other: Other:
Other: Of iron or nonalloy steel: Other."

The instant steel fittings lined with a plastic insulating material fall
under heading 8547, HTSUSA. Those plastic-lined fittings that are
threaded are classified under subheading 8547.90.0030, HTSUSA, which
provides for: "Insulating fittings for electrical machines, appliances
or equipment, being fittings wholly of insulating material apart from
any minor components of metal (for example, threaded sockets)
incorporated during molding solely for the purposes of assembly, other
than insulators of heading 8546; electrical conduit tubing and joints
therefor, of base metal lined with insulating material: Other:
Electrical conduit tubing and joints therefor, of base metal lined with
insulating material: Joints: Threaded. " Those plastic-lined fittings
that are not threaded are classified under subheading 8547.90.0040,
HTSUSA, which provides for: "Insulating fittings for electrical
machines, . . . : Other: Electrical conduit tubing and joints therefor,
of base metal lined with insulating material: Joints: Other."

The threaded bolts fall under heading 7318, HTSUS. They are classified
under subheading 7318.15.20, HTSUS, with further delineation depending
on the diameter and type. Subheading 7318.15.20, HTSUS, provides for
"Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter
pins, washers (including spring washers) and similar articles, of iron
and steel: Threaded articles: Other screws and bolts, whether or not
with their nuts or washers: Bolts and bolts and their nuts or washers
entered or exported in the same shipment."

The threaded screws also fall under heading 7318, HTSUS. They are
classified either under subheading 7318.15.60, HTSUS, or subheading
7318.15.80, HTSUS, with further delineation depending on the diameter
and type. Subheading 7318.15.20, HTSUS, provides for, "Screws, bolts,
nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers
(including spring washers) and similar articles, of iron and steel:
Threaded articles: Other screws and bolts, whether or not with their
nuts or washers: Other: Having shanks or threads with a diameter of less
than 6 mm." Subheading 7318.15.80, HTSUS, provides for "Screws, bolts,
nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers
(including spring washers) and similar articles, of iron and steel:
Threaded articles: Other screws and bolts, whether or not with their
nuts or washers: Other: Having shanks or threads with a diameter of 6 mm
or more."

However, based upon our determination with respect to the effective date
of HQ 966958, and based upon 19 CFR 177.9(a), the entries at issue
should be liquidated under subheading 7326.90.8586, HTSUSA. The 2002
general rate of duty for this subheading is 2.9 percent. Accordingly,
you are instructed to ALLOW the protest.

In accordance with the Protest/Petition Processing Handbook (CIS HB,
January 2002, pp. 18 and 21), you are to mail this decision, together
with the Customs Form 19, to the protestant no later than 60 days from
the date of this letter. Any reliquidation of the entry in accordance
with the decision must be accomplished prior to mailing of the decision.
Sixty days from the date of the decision the Office of Regulations and
Rulings will make the decision available to CBP personnel, and to the
public on the CBP Home Page on the World Wide Web at www.cbp.gov, by
means of the Freedom of Information Act, and other methods of public
distribution. Duty rates are provided for your convenience and are
subject to change. The text of the most recent HTSUS and the
accompanying duty rates are provided on the World Wide Web at
