Part VI--Proposed New Industry Structure for Electrical Equipment, Appliance and
Component Manufacturing

Section A--NAICS Structure

North American Industry Classification System

(NAICS)

Agreement Number 9

    This Document represents the proposed agreement on the structure of the North American
Industry Classification System (NAICS) for the following industries: Electrical Equipment,
Appliance and Component Manufacturing.
    The detailed NAICS structure along with a brief description of the structure is attached
(Attachments 1 and 2). Each country agrees to release a copy of the proposed NAICS
structure to interested data users. Comments received will be shared among the countries and
additional discussions will be held before a final decision on the structure is made. Each
country may add additional detailed industries, below the 4-digit level of NAICS, as
necessary to meet national needs, so long as this additional detail aggregates to a 4-digit
NAICS level in order to ensure full comparability among the three countries.
 This NAICS structure was presented and provisionally accepted at the NAICS Committee
meeting held on August 30, 1995 - September 1, 1995 in Washington, D.C.

Attachment 2--North American Industry Classification System

Draft Classification for:

Electrical Equipment, Appliance and Component Manufacturing

    Representatives of the statistical agencies of Canada, Mexico, and the United States agree
to a draft industrial classification for these industries.
    This draft classification applies to the subsector, Electrical Equipment, Appliance and
Component Manufacturing. This subsector is sub-divided into four industry groups and nine
industries. This subsector is part of the Manufacturing sector.

A General Outline

    The Electrical Equipment, Appliance and Component Manufacturing industries create
products that generate, distribute and use electrical power. While establishments classified in
many parts of manufacturing make products that use electricity, the manufacture of electric
lighting equipment and signs and household appliances require particular attention to the
application of electricity. That is the reason for their inclusion in this subsector.
    Electrical Equipment Manufacturing establishments produce goods that generate and
distribute electrical power, or that are made with similar production technology, such as
motors, generators, transformers and switchgear apparatus. Other Electrical Equipment and
Component Manufacturing establishments produce devices for storing electrical power
(e.g., accumulators), for transmitting electricity (e.g., insulated wire), and accessories for
carrying current. Activities in both Electrical Equipment Manufacturing and Other Electrical
Equipment and Component Manufacturing industry groups all involve the manufacture of
machinery for the generation and distribution of power.

Limitations and Constraints of the Classification

    In the Electrical Equipment, Appliance and Component Manufacturing subsector, most
activities identified in one country exist in the others. The way activities are combined in
establishments differs to some extent in the different countries. For example, Canada cannot
separate the manufacturing of household cooking equipment from refrigerators and freezers
because these activities are often combined in Canadian establishments. Often an activity is
not economically significant to the same degree in all countries. For example, size constraints
in Canada prohibit separating the manufacture of batteries from accumulators. For those
reasons, some NAICS industries in this subsector are broader than would be desirable in a
system that distinguishes as does NAICS among production processes. Each country will
publish additional categories that comprise subdivisions of NAICS industries to present data
for activities that are nationally significant.
    For those users requiring detailed commodity information, each country will publish
information on the products of these industries. Efforts are also underway to harmonize the
commodity classifications to allow comparability of these statistics.

Relationship to ISIC

    Most of the NAICS four-digit industries created in this subsector can be assigned to
Division 28, Manufacture of Fabricated Metal Products, Except Machinery and Equipment or
Division 31, Manufacture of Electrical Machinery and Apparatus, nec of the current
International Standard Industrial Classification of all Economic Activities (ISIC, Revision 3)
of the United Nations. Therefore, data tabulated using NAICS can readily be re-tabulated
according to ISIC with the following exception: NAICS industry, All Other Electrical
Equipment and Component Manufacturing includes non-electrical products of graphite or
carbon because those nonelectrical products are made in the same establishments as electrical
graphite and carbon products. In ISIC, this activity is included in Division 26, Manufacture
of Other Non-Metallic Mineral Products.

Some Changes to the National Classifications

    For Canada, the Electrical Equipment, Appliance and Component Manufacturing
subsector is part of the existing Canadian classification's Electrical and Electronic Products
Industries major group. A large part of that major group will form part of the new NAICS
Computer and Electronic Product Manufacturing subsector. As well, establishments that
draw wire and insulate it are classified in Primary Metal Manufacturing in NAICS. This
subsector includes electric signs that are classified in Miscellaneous Manufacturing in the
current Canadian classification. The structures of the NAICS and Canadian classifications are
similar. There are fewer industries in NAICS, but national industries will provide the same
level of detail as before.
    For Mexico, the Electrical Equipment, Appliance and Component Manufacturing
subsector includes many of the activities currently in the Mexican classification's
Manufacture and Assembly of Machinery, Equipment and Electrical Accessories and
Manufacture and Assembly of Electric and Non-Electric Appliances and Accessories for
Home Use. However, NAICS includes the manufacturing of turbines and some engines in
Machinery Manufacturing, rather than in electrical machinery and it classifies electrical
apparatus for transportation equipment in Transportation Equipment Manufacturing. The
structure of the NAICS subsector is not similar to that of the corresponding areas of the
Mexican classification. There are fewer industries in NAICS, but national industries will
provide the same level of detail as before.
    For the United States, a major change to the structure encompasses the transfer of twelve
industries out of the existing 1987 SIC major group, Electronic and Other Electrical
Equipment and Components Except Computer Equipment, to the proposed new NAICS
subsector, Computer and Electronic Product Manufacturing. The industries moved are those
that manufacture electronic components such as printed circuit boards and semiconductors
and related devices. Two industries that produce electrical equipment/components for motor
vehicles, aircraft etc. have been moved to the Transportation Equipment Manufacturing
subsector.
    Additional changes for the United States for this subsector include moving the
manufacture of electric signs from the Miscellaneous Manufacturing subsector and the
creation of a new industry from the Primary Metal Manufacturing subsector for the
manufacture of insulated wire and cable from purchased wire. The relocation of insulated
wire from Primary Metal Manufacturing to the Electrical Equipment, Appliance and
Component Manufacturing subsector is a significant improvement of the classification with
respect to the production principle as it now allows for a distinction between establishments
that first draw wire and then insulate it and those that only insulate.

Achievement of Objectives

    The classification meets the objectives for the North American Industry Classification
System (NAICS). It is comprised of industries that group establishments with similar
production processes, that is, it applies the production-oriented economic concept. In the
main, the hierarchical structure of the classification also follows the production concept.
    The classification achieves comparability for the three participating countries. Based on
existing data, all three countries expect to be able to publish data regularly at the industry (4-
digit) level of the structure. All countries agree on the detailed definitions of the industries.
    Other objectives of the NAICS project are not as relevant in this area of the classification
as in others. These objectives are the delineation of new and emerging industries, service
industries, and industries engaged in the production of advanced technologies. The industrial
sector in question is relatively mature, generally produces goods, and employs relatively
stable technology. Therefore, the emphasis is on the objectives listed above.
    The industries have high specialization ratios, and they are economically significant. The
detail and structure of the classification are balanced in size. This enhances the
classification's suitability for sampling, data-publishing and other aspects of survey
operations. Finally, disruptions to time series, while they exist, have been minimized. The
statistical agencies can develop statistical "links", to enable the re-tabulation of time series on
the new NAICS classification structure.

Section B-Annex: United States National Industry Detail

    As explained in the Structure presentation of this notice, for a number of reasons 4-digit
industries in the three NAICS industry subsectors presented in Part 1, Section A--Attachment
1, contain less detail than is currently in the U.S. SIC system, and less detail than is required
to meet important analytical requirements in the U.S. The three country agreement on NAICS
envisions that each country may develop national detailed industries below the NAICS
industry level, so long as the national detail can be aggregated to the NAICS classification,
thus assuring full North American comparability.
    The ECPC is proposing U.S. 5-digit industry detail for the NAICS industry subsector
covered in Part I of this notice. For cases where no 5-digit detail is shown, the ECPC is
proposing that the NAICS 4-digit industries will also represent the most detailed U.S.
industries.

       The definitions of status codes are as follows: E-existing industry; N-new industry; R-revised industry; and * means "part of". The
       abbreviation NEC is used for Not Elsewhere Classified.

Description of Changes to the U.S. System

    A number of the changes listed in this section were made for reasons of
international comparability. Where one or more of the three North American countries
had different definitions of an industry classification, adjustments to the definitions in
one or more countries were required. In constructing NAICS, the three countries
agreed to move, where change was required to attain international comparability, in
the direction of the country or countries whose existing classification definitions most
closely corresponded to the production-oriented concept adopted for NAICS. Cases
where the U.S. changed are listed below; other cases where Canada or Mexico moved
toward the U.S. classification are not, of course, listed in this section.
    Three new industries were added to the 1997 industry structure for this subsector.
    Electric Sign Manufacturing from part of 1987 SIC Code 3993, Signs and
Advertising Specialties, to achieve international comparability. The U.S. and Canada
moved to match Mexico.
    Fiber Optic Cable Manufacturing (not drawn) from part of 1987 SIC 3357,
Drawing and Insulating of Nonferrous Wire, for reasons of international comparability
and because of the highly specialized production processes involved, and because this
is a newly-emerging technology.
    Other Communication and Energy Wire Manufacturing (insulating of only) from
part of 1987 SIC Code 3357, Drawing and Insulating of Nonferrous Wire, for
purposes of
international comparability and to better reflect production principles. The U.S.
moved to match Canada and Mexico.
    Sixteen industries were transferred out of 1987 SIC Major Group 36, Electronic
and Other Electrical Equipment and Components, Except Computer Equipment. Of
the sixteen industries, twelve are included in 1997 NAICS Subsector, Computer and
Electronic Product Manufacturing, a new subsector; two transferred to NAICS
Subsector, Transportation Equipment Manufacturing; and two were divided into
several activities that were transferred into the 1997 NAICS Subsectors, Computer and
Electronic Product Manufacturing and Transportation Equipment Manufacturing; and
the new Information sector.
    The following twelve industries were transferred to 1997 NAICS Subsector,
Computer and Electronic Product Manufacturing:
    Household Audio and Video Equipment
    Telephone and Telegraph Apparatus
    Radio and Television Broadcasting and Communication Equipment
    Communications Equipment, NEC
    Electron Tubes
    Printed Circuit Boards
    Semiconductors and Related Devices
    Electronic Capacitors
    Electronic Resistors
    Electronic Coils, Transformers, and Other Inductors
    Electronic Connectors
Magnetic and Optical Recording Media.
    Two industries were transferred from 1987 SIC Major Group 36, Electronic and
Other Electrical Equipment and Component, Except Computer Equipment, to 1997
NAICS Subsector, Transportation Equipment Manufacturing. They were 1987 SIC
3647, Vehicular Lighting Equipment, and 1987 SIC 3694, Electrical Equipment for
Internal Combustion Engines.
    Record publishing moved from part of 1987 SIC 3652, Phonograph Records and
Prerecorded Audio Tapes and Disks, to the new NAICS Information sector. The
remaining activities were transferred to 1997 NAICS Subsector, Computer and
Electronic Product Manufacturing.
    1987 SIC 3679, Electronic Components, NEC, was split three ways. One part,
electronic control modular chips for motor vehicles, was transferred to 1997 NAICS
Subsector, Transportation Equipment Manufacturing, and the other two parts,
communication equipment and other electronic components, moved to two separate
industries within 1997 NAICS Subsector, Computer and Electronic Product
Manufacturing.
    Three activities transferred into the 1997 Electrical Equipment, Appliance and
Component subsector:
    Transformers for arc-welders from part of 1987 SIC 3548, Electrical and Gas
Welding and Soldering Equipment, to Power, Distribution, and Specialty Transformer
Manufacturing, to achieve international comparability. Canada had this in CSIC
Major Group 33, Electrical and Electronic Products Industries.
    Lamp shades of paper and textiles from part of 1987 SIC 3999, Manufacturing
Industries, NEC, to Residential Electric Lighting Fixture Manufacturing, to achieve
international comparability. Canada had lamp shades in CSIC MG 33, Electrical and
Electronic Products Industries.
    Water coolers from part of 1987 SIC 3585, Refrigeration and Heating Equipment,
to Household Refrigerator and Home and Farm Freezer Manufacturing, to achieve
international comparability. The U.S. and Canada moved to match Mexico.
    Also, several activities transferred within the Electrical Equipment, Appliance and
Component Manufacturing subsector. The number of electrical equipment, appliance
and component manufacturing industries decreased from 37 in 1987 to 23 in 1997.
Excluding the sixteen industries that were moved out of this subsector, all but 2 of the
22 remaining 1987 industries are comparable within three percent of the 1997
industries; both of the time series breaks involve splitting activities out of old NEC
categories.
