Part V--Proposed New Industry Structure for Machinery Manufacturing

Section A--NAICS Structure

North American Industry Classification System

(NAICS)

Agreement Number 8

    This Document represents the proposed agreement on the structure of the North American
Industry Classification System (NAICS) for the following industries:
Machinery 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 Committee meeting held August
30, 1995 - September 1, 1995 in Washington, D.C.

Attachment 2--North American Industry Classification System

Draft Classification for:

Machinery 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, Machinery Manufacturing. This subsector
is sub-divided into seven industry groups and thirteen industries. The subsector will be part
of the Manufacturing sector of the classification.

A General Outline

   The industries included in the Machinery Manufacturing subsector create end products that
apply mechanical force, for example, the application of gears and levers to perform work.
Some important processes for manufacture of machinery are forging, stamping, bending,
forming, and machining that are used to shape individual pieces of metal. Processes such as
welding and assembling are used to join separate parts together. These processes are similar
to those used in metal fabricating establishments. However, machinery manufacturing
typically employs multiple metal forming processes in manufacturing the various parts of the
machine and complex assembly operations are an inherent part of the production process.
   In general, design considerations are very important in machinery production.
Establishments specialize in producing machinery designed for particular applications. Thus
design is considered to be part of the production process for the purpose of implementing
NAICS. The structure reflects this by defining industries and industry groups that produce
machinery for different applications. A broad distinction exists between machinery that is
generally used in a variety of industrial applications (general purpose machinery) and
machinery that is designed to be used in a particular industry (special purpose machinery).
Three industry groups consist of special purpose machinery - Agricultural, Construction, and
Mining Machinery Manufacturing; Industrial Machinery Manufacturing; and Commercial and
Service Industry Machinery Manufacturing. The other industry groups produce general-
purpose machinery - Heating, Ventilation, Air Conditioning, and Commercial Refrigeration
Manufacturing; Metalworking Machinery Manufacturing; Engine, Turbine, and Power
Transmission Equipment Manufacturing; and Other General Purpose Machinery
Manufacturing.
Limitations and Constraints of the Classification

    Relatively broad industries were created in several areas including: Other Industrial
Machinery Manufacturing; Heating, Ventilation, Air Conditioning, and Commercial
Refrigeration Manufacturing; and Engine, Turbine and Power Transmission Equipment
Manufacturing. Occasionally, these aggregations are a consequence of differences in the
degree of specialization of the three countries. For example, Canada cannot support a
separation of mining machinery manufacturing from oil and gas field machinery
manufacturing because of the combination of these activities in the same establishments.
   More often, size constraints prohibit separation of activities in Canada or Mexico. For
example, separate industries are possible for textile machinery manufacturing in the United
States and Mexico, or for paper industry machinery manufacturing in Canada and the United
States. But due to size constraints, it is not possible to create the textile machinery
manufacturing industry in Canada or the paper industry machinery manufacturing industry in
Mexico. Therefore, textile machinery manufacturing and paper machinery manufacturing are
included in the four-digit industry, Other Industrial Machinery Manufacturing.
   Each country will publish additional categories that comprise sub-divisions of 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 also are underway to harmonize the
commodity classifications to allow for greater comparability of these statistics.

Relationship to ISIC

   Ten of the thirteen four-digit industries in this subsector can be assigned to Division 29,
Manufacture of Machinery and Equipment, NEC, of the current International Standard
Industrial Classification of all Economic Activities (ISIC, Revision 3) of the United Nations.
The following three industries belong largely to ISIC Division 29, with the exception of the
activities indicated: Mining, Oil and Gas Field Machinery (drilling bits for oilfield and gas
drilling equipment); Commercial and Service Industry Machinery Manufacturing (optical
instruments and lenses and photographic equipment and supplies, except photographic films,
paper, and chemicals); and Other General Purpose Machinery (balance equipment, other than
automotive wheel). However, because the exceptions indicated are a relatively small part of
the output of these two NAICS industries, one can combine the industries of NAICS for this
subsector, and be quite comparable to ISIC 29.

Some Changes to the National Classifications

   The Canadian classification's Machinery Industries major group is similar in coverage to
the subsector proposed here. The manufacturing of heating equipment, now treated as metal
fabricating; of some office machinery, now classified as electrical equipment; and of engines,
now classified as transportation equipment have been moved to this subsector. Furthermore,
the structure - special-purpose machinery and general-purpose machinery - is similar.
However, the classification has more detail, with thirteen industries compared to seven; the
Canadian national detail adds three more.
   The Mexican classification's Manufacture, Repair and Assembly of Machinery and
Equipment for Specific Purposes and Manufacture, Repair and Assembly of Machinery and
Equipment for General Use have a combined coverage similar to the subsector proposed here.
The manufacturing of heating equipment, now treated as metal fabricating, of some office
machinery, now classified as electrical equipment, and of engines now classified as
transportation equipment, have been moved to this subsector. Furthermore, the structure -
special-purpose machinery and general-purpose machinery - is similar. The amount of detail
in the subsector is similar to that of the existing classification.

   For the United States, a major change is the movement of computers and peripherals out of
this group to the new subsector for Computers and Electronic Product Manufacturing.
Heating equipment, currently in the 1987 SIC Fabricated Metal major group, and optical
instruments, lenses, and photographic equipment, currently in the 1987 SIC Instruments and
Related Products major group, have been transferred into this subsector. Other changes
involve the movement of a number of relatively small activities from one national industry to
another to achieve comparability with Canada and Mexico, and/or to better meet production
principles. Otherwise, the new structure, with U.S. national industry detail, is comparable
with the 1987 SIC. For example, only seven 1987 U.S. industries have time series breaks that
amount to more than 3 percent of the industry value of shipments in 1992.

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 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 (4-digit level) and structure of the classification are balanced in size. This enhances the
classification s suitability for sampling and other aspects of survey operations. Finally,
disruptions to time series, while they exist, have been minimized. Most of the changes at the
detail to existing classifications are marginal. The major changes are well-identified and can
be taken into account in linking time series.

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 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 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 industry subsector covered in
Part I of this notice. For cases where no 5-digit detail is shown, the ECPC is proposing that
the 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 of
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.
     Five new industries were added to the 1997 industry structure for this industry
subsector. New industries were created for:
     Semiconductor Machinery Manufacturing from part of 1987 SIC 3559, Special
Industry Machinery, NEC, in response to an industry proposal and because of the
highly specialized production processes involved.
     Rubber and Plastic Industry Machinery Manufacturing from part of 1987 SIC
3559, Special Industry Machinery, NEC, in response to a plastics industry proposal
and because of the highly specialized production processes involved. Rubber
machinery was included with plastics machinery because of shared production
characteristics.
     Air Purification Equipment Manufacturing from part of 1987 SIC 3564, Industrial
and Commercial Fans and Blowers and Air Purification Equipment, in response to an
industry proposal and because of highly specialized production processes involved.
     Office Machinery Manufacturing from part of 1987 SIC 3578, Calculating and
Accounting Machinery, Except Electronic Computers, and from part of 1987 SIC
3579, Office Machines, NEC, to achieve international comparability. Mexico has a
separate class already broken out. More advanced electronic office machinery is
placed in the new Computer and Electronic Product Manufacturing subsector, because
the production processes are very different.
     Photographic and Photocopying Equipment Manufacturing from Part of 1987 SIC
3861, Photographic Equipment and Supplies, to achieve international comparability.
     Seven industries were removed from this industry group, and transferred
elsewhere. All seven of these were moved to achieve international comparability, or
to create the new Computer and Electronic Product Manufacturing subsector.
     Industrial Pattern Manufacturing was transferred into the Fabricated Metal
Product Manufacturing subsector.
     Ball and Roller Bearing Manufacturing was transferred into the Fabricated Metal
Product Manufacturing subsector.
     Carburetor, Piston, Piston Ring, and Valve Manufacturing was transferred into the
Transportation Equipment Manufacturing subsector.
     Electronic Computer Manufacturing was transferred into the Computer and
Electronic Component Manufacturing subsector.
     Computer Storage Product Device Manufacturing was transferred into the
Computer and Electronic Product Manufacturing subsector.
     Computer Terminal Manufacturing was transferred into the Computer and
Electronic Product Manufacturing subsector.
     Computer Peripheral Equipment, NEC was transferred into the Computer and
Electronic Product Manufacturing subsector.

     Fifteen activities transferred out of 1987 Major Group 35, Industrial and
Commercial Machinery and Computer Equipment, and are described more fully in
their new respective subsectors.
     Ferrous and nonferrous mold manufacturing was transferred from part of 1987
SIC 3544, Special Dies and Tools, Die Sets, Jigs and Fixtures, and Industrial Molds,
into the Primary Metal Manufacturing subsector.
     Hand hair clippers for animals and metal corral, stall, and holding gate
manufacturing were transferred from part of 1987 SIC 3523, Farm Machinery and
Equipment, into the Fabricated Metal Product Manufacturing subsector.
     Nonpowered lawn mower manufacturing was transferred from part of 1987 SIC
3524, Lawn and Garden Tractors and Home Lawn and Garden Equipment, into the
Fabricated Metal Product Manufacturing subsector.
     Precision measuring tool manufacturing was transferred from part of 1987 SIC
3545, Cutting Tools, Machine Tool Accessories, and Machinists' Precision Measuring
Devices, into the Fabricated Metal Product Manufacturing subsector.
     Metal air cargo container and metal pallet manufacturing was transferred from
part of 1987 SIC 3537, Industrial Trucks, Tractors, Trailers, and Stackers, into the
Fabricated Metal Product Manufacturing subsector.
     Machine shops were transferred from part of 1987 SIC 3599, Industrial and
Commercial Machinery and Equipment, NEC, into the Fabricated Metal Product
Manufacturing subsector, to achieve international comparability. Canada had machine
shops in CSIC 30, Fabricated Metal Products Industries.
     Stationery engine radiator manufacturing was transferred from part of 1987 SIC
3519, Internal Combustion Engines, NEC, into the Transportation Equipment
Manufacturing subsector.
