Section A - NAICS Structure

NORTH AMERICAN INDUSTRY CLASSIFICATION SYSTEM

                                         (NAICS)


                               AGREEMENT Number 1


This Document represents the proposed agreement on the structure of the North American
Industry Classification System (NAICS) for the following industries:

                     Petroleum and Coal Products Manufacturing
                     Chemicals Manufacturing
                     Rubber and Plastics Products 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
discussions 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 May 18 and 19 in Ottawa,
Canada.

ACCEPTED:                            Signature                                        Date

                 North American Industry Classification System

Draft Classification for:           Petroleum and Coal Products Manufacturing
                                    Chemicals Manufacturing
                                    Rubber and Plastics Products Manufacturing


   Representatives of the statistical agencies of Canada, Mexico and the United States have
agreed to a draft industry classification for these industries.
   The draft classification provides for three industry subsectors, Petroleum and Coal
Products Manufacturing; Chemicals Manufacturing; and Rubber and Plastics Products
Manufacturing. These are further subdivided into ten industry groups and thirty industries.
These industry subsectors will be part of the Manufacturing sector(s) of the NAICS
classification.

Achievement of Objectives

   The classification meets the objectives for the North American Industry Classification
System. 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
level of the structure. All countries agree on the detailed definitions of the industries.
   The classification improves comparability with other countries. With the exception of the
"miscellaneous" industries, all industries are compatible with the 2-digit level of the current
International Standard Industrial Classification of All Economic Activities (ISIC, Revision 3)
of the United Nations. This means that each NAICS industry is the same as, or part of, a
single ISIC 2-digit Division. Therefore, data tabulated using NAICS can be readily re-
tabulated according to ISIC. This comparability extends to higher levels of the NAICS. For
example, there is little difference between the NAICS Chemical Industries, and ISIC 24,
Manufacture of Chemicals and Chemical Products.
   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 industry
sector in question is relatively mature, generally produces goods, and has always employed
relatively advanced technology. Therefore the emphasis was on the production concept and
comparability.
   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 at the NAICS industry level to time series have been kept to a
minimum. 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.
Limitations of the Classification

   On the other hand, there are some analytical requirements which cannot be met by the
industry classification. In particular, there is a demand for data on the production of all
articles of plastic. This cannot be accommodated by the industry classification due to the
ubiquity of plastic in manufactured products. Many industrial activities that incorporate
plastics in combination with other materials are classified elsewhere in manufacturing.
   Similarly, a breakdown of plastics industries which follows market lines cannot be
produced. This arises from the fact that, in general, plastics fabricators can and do switch
production from one type of product to another as market conditions change. In some cases a
market or demand category does correspond to a distinct production process, in which case an
industry can be defined which supports the needs of both supply-oriented and demand-
oriented analyses. An example of this is the NAICS Plastics Bottles Manufacturing industry.
However, in general, this is not possible because of the way businesses have organized their
production facilities.
   Users requiring data for demand analysis can instead make use of statistics based on
commodity classifications. Each country publishes such data. Efforts are underway to
harmonize the commodity classifications to allow comparability of these statistics.

Constraints on the NAICS Classification

   There were a few factors which constrained the structure and detail of the classification in
the area under consideration.
   An issue related to the coding structure is the ability to publish and the economic
significance of the items defined in the classification. In the chemicals industry, most
activities which were identified in one country exist in the others. However, often an activity
is not economically significant to the same degree in all countries. Further, data for some
significant activities cannot be published for a particular country for reasons of
confidentiality, such as the matches manufacturing industry in Canada. Finally, the way
activities are combined in establishments differs to some extent in the different countries. A
structure could have been developed which specified such activities in NAICS, but the
resulting statistical tables for any given country would have numerous insignificant or
suppressed entries. It was preferable to adopt an operating rule that the NAICS industries for
this area must be economically significant and publishable. It is anticipated that each country
will publish additional categories which comprise sub-divisions of NAICS industries, to
present data for activities which are nationally significant.
   Other constraints did involve the nature of the industries to be classified. In the case of
chemicals, it was essential for NAICS to include Petrochemicals Manufacturing as an
industry, due to the significance of this activity in Mexico. This is a major change for the
United States and Canada. It involves some extra work for these countries in implementing
the classification, since the direct assignment of industry codes from commodity output
information (a common technique for most manufacturing industries) cannot be used without
modification. Nevertheless, the importance of the activity, and the fact that it is based on a
well-defined production process, resulted in its inclusion in NAICS.
A General Outline

    The Petroleum and Coal Products Manufacturing subsector is based on the transformation
of crude petroleum and coal into usable products. The dominant process is petroleum
refining, which involves the separation of crude petroleum into component products through
such techniques as cracking and distillation.
    The Chemicals Manufacturing subsector is based on the transformation of organic and
inorganic raw materials by a chemical process, and the formulation of products. This
subsector distinguishes the production of basic chemicals, which comprises the first industry
group, from the production of intermediate and end products produced by further processing
of basic chemicals, which make up the remaining industry groups.
    Concerning Basic Chemicals Manufacturing industries, data users will note that a general
distinction has not been made between organic and inorganic basic chemicals. The
production of organic and inorganic industrial gases is a single activity. In Mexico, the
production of organic and inorganic dyes and pigments commonly takes place in the same
establishments.
    The industry subsector Rubber and Plastics Products Manufacturing includes
establishments which make goods by processing raw rubber and plastics materials. To the
extent possible, this subsector is restricted to industrial activities whose core technology is the
production of products made of just one material, rubber or plastic. Many manufacturing
activities use rubber or plastic as one of several inputs, to the extent that the core technology
relates to the type of product produced. An example of this is the manufacture of footwear.
Typically, more than one material is used to produce shoes, so technologies which allow
disparate materials to be formed and combined are of central importance in describing the
footwear manufacturing activity. Such activities, for example footwear and furniture
manufacture, are generally classified elsewhere than in the industry subsectors organized
around the core technologies of rubber and plastic.
    The main exception to this principle is Tires and Tubes Manufacturing. The production of
tires is included in Rubber Products Manufacturing to minimize the disruption of time series
and for comparability with ISIC, rather than because it particularly fits the general production
process of the major group subsector. Tires are normally made from several materials.
    A distinction is made between rubber and plastics products at the industry group level. It is
not a rigid distinction, as can be seen from the definition of Rubber and Plastics Hose and
Belting Manufacturing. As materials technology improves, plastics are increasingly being
used as a substitute for rubber. Eventually, the distinction may disappear as a basis for
defining establishments, and be limited to the commodity classification.
    The Plastics Products Manufacturing industry subsector consists generally of activities
involving the processing of plastics materials in forms such as pellets into intermediate or
final products, using such processes as extrusion and injection moulding. Within most of
these industries, the production process is such that a wide variety of products can be
produced.

Some Changes to the National Classifications

   This section highlights some of the significant changes to existing national classifications.
   In Petroleum and Coal Products Manufacturing, the main change to an existing
                                                               1
classification is the inclusion of activities currently in CSIC 2721, Asphalt Roofing Industry,
in NAICS Asphalt Paving and Roofing and Saturated Materials Manufacturing. It is included
here because the defining feature of the production process (the saturation of paper with
asphalt) is the manipulation of asphalt.
   The production of alumina from bauxite is currently classified in USIC 2819, Industrial
Inorganic Chemicals, NEC. The production of alumina does involve the use of a chemical
process, but it is analogous to the chemical activities involved in the processing of other ores
in smelting and refining industries. It will therefore be treated as an activity in the primary
metals, rather than in NAICS Other Inorganic Chemicals Manufacturing.
   The production of artificial and synthetic fibers is treated as a textile activity in CSIC.
While the outputs are a basic raw material for textile production, the fiber production itself is
an activity with chemical characteristics. It is basically a polymerization process, similar to
the production of synthetic resins. It is therefore included in the NAICS Chemicals
Manufacturing subsector (Artificial and Synthetic Fibers and Filament Manufacturing).
   The manufacture of photographic chemicals and sensitized paper is classified in CSIC
3912, Other Instruments and Related Products Industry and in USIC 3861, Photographic
Equipment and Supplies. NAICS classifies the production of these goods in Miscellaneous
Chemical Products Manufacturing, since their production process is a chemical products
process, not an equipment manufacturing process.
   The new classification eliminates the 2-digit distinction between rubber products and
plastics products which was found in CSIC (groups 15 and 16). NAICS combines CSIC
group 15, rubber products, and group 16, plastics products, into one subsector, Rubber and
Plastics Products Manufacturing.
   NAICS Tires and Tubes Manufacturing includes an activity--the retreading and recapping
of tires--which in CSIC and USIC is classified as non-manufacturing. The tire retreading and
recapping activity is included in manufacturing because it involves more than just a repair.
This activity is an example of "re-building", which occurs when a manufactured article is
returned to usability using processes similar to those used in the original manufacturing
operation. Re-building activities will be included in manufacturing in NAICS.
   NAICS Rubber and Plastics Products Manufacturing excludes the manufacture of
footwear, furniture and toys of rubber and plastic. This is a significant change to CMAP,
which includes these activities in CMAP 3550, Rubber Industry and 3560, Manufacture of
Plastics Products.
   NAICS Unsupported Plastics Films, Sheet and Bags Manufacturing includes the
manufacture of plastic laminates for packaging and plastic bags, which are classified
respectively in USIC 2671, Packaging Paper and Plastics Film, Coated and Laminated and
2673, Plastics, Foil and Coated Paper Bags.
   NAICS Other Plastics Products Manufacturing includes the manufacture of most of the
plastics motor vehicle parts, such as interior and exterior trim of plastics, which are classified
in CSIC 3256, Plastics Parts and Accessories for Motor Vehicles.


CSIC refers to the Standard Industrial Classification of Canada, 1980 Revision. USIC refers
to the Standard Industrial Classification of the United States, 1987 Revision. CMAP refers to
the Classification of Activities and Products of Mexico.
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 inPart 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 three NAICS industry
subsectors covered in Part I of this notice. In the following tables, proposed 5-digit detail is
indicated in italics. 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.
                                                                                    TABLE 1
     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

1.   Petroleum and Coal Products Manufacturing - There was one change from the 1987
     industry structure for this sector.

          Coke ovens, not operated with a blast furnace transferred from 1987 Industry Code
          3312, Blast Furnaces and Steel Mills to the 1997 Other Petroleum and Coal
          Products, NEC.

The number of 1997 petroleum and coal products industries remains unchanged at five from
1987. For time series linkage, all five 1987 industries are comparable within three percent of
the 1997 industries.

2.   Chemicals Manufacturing - There were five new industries added to the 1997 industry
     structure for this industry subsector. New industries were created for:

          Petrochemicals Manufacturing from parts of 1987 Industry Code 2865, Cyclic
          Crudes and Intermediates and 1987 Industry Code 2869, Industrial Organic
          Chemicals, NEC.

          Organic Dyes and Pigments Manufacturing from part of old Industry Code 2865,
          Cyclic Crudes and Intermediates.

          In-Vitro Diagnostic Substances Manufacturing from part of old Industry Code
          2835, Diagnostic Substances.

          Photographic Films, Papers, Plates, and Chemicals Manufacturing from part of
          1987 Industry Code 3861, Photographic Equipment and Supplies.

          Custom Compounding Purchased Resins Manufacturing transferred from the 1987
          Major Group Code 30, Rubber and Plastic Products.

Two activities transferred out of 1987 Major Group Chemicals and Allied Products.

          Alumina transferred from 1987 Industry Code 2819, Industrial Inorganic
          Chemicals, NEC into Primary Aluminum Manufacturing.

          Ethyl Alcohol transferred from 1987 Industry Code 2869, Industrial Organic
          Chemicals into Distilled and Blended Liquors Manufacturing.

Two activities transferred into the 1997 Chemicals Manufacturing.

          Drawing ink and India ink transferred from old Industry Code 3952, Lead Pencils
          and Art Goods into Printing Ink Manufacturing.
          Matches transferred from old Industry Code 3999, Manufacturing Industries, NEC
          into All Other Miscellaneous Chemical Preparations.

Also, there were several activities that transferred within the chemical industry. The number
of chemical industries increased from 29 in 1987 to 34 in 1997. For time series linkage, 25 of
the 29 1987 industries are comparable within three percent of the 1997 industries.

3. Rubber and Plastics Products Manufacturing - There were six new industries added to
the 1997 industry structure for this industry subsector.

          Tire Rebuilding and Repair transferred from the 1987 Services Major Group
          Code 75, Auto Repair, Services, and Parking.

          Unsupported Plastics Packaging Films and Sheets Manufacturing from part of
          1987 Industry Code 2671, Paper Coated and Laminated, NEC.

          Unsupported Plastics Bags from part of 1987 Industry Code 2673, Bags: Plastics,
          Laminated, and Coated.

          Polystyrene Foam Products from part of 1987 Industry Code 3086, Plastics Foam
          Products.

          Urethane Foam Products from part of 1987 Industry Code 3086, Plastics Foam
          Products.

          Resilient Floor Coverings from parts of 1987 Industry Code 3069, Fabricated
          Rubber Products, NEC and 1987 Industry Code 3996, Hard Surface Floor
          Coverings, NEC.

Three industries were removed from this industry group.

          Rubber and Plastics Footwear transferred into the 1997 NAICS Industry Subsector,
          Leather and Allied Products Manufacturing.

          Gaskets, Packings, and Sealing Devices were deleted and the products were split
          into various residual industries by material.

          Custom Compounding Purchased Resins transferred into the 1997 NAICS Industry
          subsector, Chemicals Products Manufacturing.

One activity transferred out of the 1987 Major Group, Rubber and Plastics Products.

          Rubberized Fabric transferred from the 1987 Industry Code 3069, Fabricated
          Rubber Products, NEC to 1997 NAICS Industry, Coated Fabric Mills including
          Rubberized Fabric Mills.
Also, there were several activities that transferred within the rubber and plastics products
industries. The number of rubber and plastics products industries increased from 15 in 1987
to 17 in 1997. For time series linkage, 13 of the 15 1987 industries are comparable within
three percent of the 1997 industries.
