For the description how to request a new classification class, please see: Classification Class (Create Change Request).
ECLASS is a system for classification and product description. For ECLASS as a classification system, the most fundamental structural element is the classification class. With the help of classification classes products are devided into certain categories of similar products, the product groups. ECLASS is a monohierarchical classification system, i.e. every product group is to be found only once in the hierarchical tree structure. Every classification class has a unique identifier (IRDI), a preferred name and a coded name that represents the classification structure (see below). With the development of ECLASS 7.1, the definition of a classification class was defined as a mandatory field, i.e. starting with ECLASS 7.1 every new classification class has to have a definition. That does not imply that all classification classes that were created before 7.1 will have a definition as well.
ECLASS consists of a four-level hierarchy of classification classes (i.e. a tree structure), the first level being the most general, the fourth level being the most specific. For the relation between levels there is a free inheritance relation. This allows the construction of a hierarchy of technical, commercial or other considerations, regardless of "mathematical" dependencies. It is important that at the lowest level (sub-group) classification of all classes are listed, which are required as part of the application. From top to bottom these hierarchical levels are:
The hierarchy of the classification classes is represented with the help of the coded name, i.e. the class code. The coded name consists of an 8-digit integer number, two digits for each hierarchical level. The number of trailing zeros in the end indicates the level of hierarchy, e.g. 16-00-00-00 (Segment "Food, beverage, tobacco"), 16-04-00-00 (Main group "Fruit"), 16-04-03-00 (Group "Berry fruit"), 16-04-03-01 (Commodity class "Blackberry"). The fourth level, the commodity class or product group is then further described with the help of properties and property values. Properties and values form the basis for the product description. See also figures 1 and 2 for an example:
A segment is the most general categorization and usually represents a certain branch or market. The current release 10.1 comprises 38 segments and an additional interim class (90-90-90-90). Figure 3 lists the ECLASS segments with the number of included classes and properties and, if available, their definition.
The ECLASS segments (release 11.0)

|16||Food, beverage, tobacco||The segment includes nutrition products of all varieties (e.g.'bread, bakery products and pasta', 'Seafood', 'Dairy product & egg','meat, poultry (minimally processed)', 'meat, poultry (raw, minimally processed)', 'beverages' and many more on the main group level). Besides regular nutrition products it also contains the segment 'Tobacco, smoking product and substitute' as a main group.||336|
|17||Machine, device (for special applications)||In segment 17, special purpose manufacturing or processing machines for a variety of industries are standardised. The main groups of this segment are divided by industries including: food processing, textile, clothing & leather, paper, construction, plastic & rubber, wood working, agriculture, graphic & arts, automated elctric trade and more.||573|
|18||Equipment f. mining, metallurgical plant, rolling mill a. foundry||This segment, typically features product classification of heavy industry equipment such as mining, metallurgical, rolling mills and foundry. The segment includes 18 main groups that divide equipment types, mostly by the material that has to be processed and/or how it is processed, for instance: metal, steel casting, melting NF metal, production of rolled profiles, production of tubes, forging, extruding and more.||370|
|19||Information, communication and media technology||This segment does not only contain telecommunication devices, antenna technology and multimedia-, entertainment-technology and much more for home, office and industrial use; it also contains software (e.g for server opration, cell-phone operation, video gaming and more), display technology, radio, mass storage and filming and camera equipment. The segment is very far developed with main groups ranging across 28 different groups of products.||1.222|
|20||Packing material||Besides familiar packaging types such as bags, cans, buckets, bottles, canisters, capsules, canisters, cartridges, boxes and crates (all called 'packing material'), this segment also includes 'package insert'-materials, 'packaging aid' (e.g. carton sealing tape) and 'food sales packaging' among other main groups.||873|
|21||Manufacturing facility, workshop equipment, tool||The segment primarily features rather lighter workshop equipment and tools. However, the scope of the segment is slightly larger than just these main groups as it also includes the main groups: facility, standardized tool parts, transport device, surveying equipment as well as cleaning devices and more.||3.250|
|22||Construction technology||Segment 22 is fairly broad in scope and far developed, as it features 47 main groups that really cater to the specificities of the various construction-skills, -tools, -service and -products required. Consequently the structure of the main groups is rather loose in its division by either type of work, type of product, product requirement, material, or work requirements. Main groups most notably even include: construction chemicals, construction service skill category; dewatering, drainage & shaft; roofing supplement unit, roof lighting; barrier, security device (construction), system for solar energy usage and more.||2.126|

|26||Energy, extraction product, secondary raw material and residue||this segment comprises in a broader sense energy and raw materials as well as secondary substances. Typical of the products is a non-uniform chemical composition, which is either predetermined by the natural occurrence or the technical production processes. These include crude oil and raw gas with approximately the first processing stages, mining, mining and quarrying products, but also raw materials from renewable resources and non-processed biomass. In contrast to the SG 39 as methyl esters of palm oil fatty acids, which are derived directly from natural fatty acids of palm oil, are listed in SG 26, while a Palmitinfettsäuremethylester is an ester of a chemically defined acid and is therefore covered by SG 39. Energy and energy sources and supply (heat, cold, different qualities of water for industrial processes, industrial gases) are also listed in SG 30||296|
|27||Electric engineering, automation, process control engineering||This segement includes devices that use, supply or transform electric energy in a variety of ways. It ranges from generators, transformers, switchgears, cables/wires and batteries to a variety of lightning devices, signals, controls, sensory technology, robotics and many more applications.||3.583|
|28||Automotive technology||This segment covers automotive technology in a very broad scope (meaning that it does not just include automobiles), which ranges from lifting vehicles (e.g. cranes), railbourne vehicles, trailers, containers and farming vehicles, to bicycles, aircraft, spacecraft and special vehicles.||406|
|29||Home economics, Home technology||The segment contains 18 main groups that are primarily ragarding household products including: kitchen-modules or -equipment, household appliance, dishes, cleaning, dispensers, household textiles, child- & baby-care products, home technology and more.||502|
|30||Auxiliary supply, additive, cleaning agent||the structuring in of SG 30 is along the application area. This shall enable the user to describe and classify substances (products) for both chemical aspects as well as their application. Typically the chemical purity associated with the use intended effect is in focus. |
On the fourth level usually products are listed with the same scope, while in the segments 31, 38, 39, the fourth level corresponds to a chemical substance. The substances are often mixtures with the same application, sometimes with similar chemical or in some cases even a uniform structure. To exclude a dual classification with a polymeric chemical in such cases the use of a characteristic term in brackets after the fuel name is used. For mixtures or polymers that are not clearly characterizable no unique CAS number is assigned
|31||Polymer||Scope: All chemical compounds, which consist of a multiplicity of monomeric units, as far as they are of technical importance, pure, at room temperature stable and can be clearly characterised by a Chemical Abstracts Number. Specialties: The polymeric compounds are overwhelmingly of organic nature. Oligomeric compounds belong to Segments 38 and 39. Polymers, which differ only in the number of their monomeric units, have the same eclass Number, e.g. PE and LLDPE.

Pharmaceutics is a science that deals with the consistence, impact, development, examination, production and delivery of medical products into the industry and pharmacies. It combines various aspects from other natural sciences, especially chemistry and biology. Medical technology combines knowledge from technical fields, especially problem solving and development, with the know-how of doctors, caretakers and other professions to improve diagnostics, therapy, nursing, rehabilitation and quality of life of people. The field of medical technology is divided into commodity products that are used for patient care taking on one hand and equipment and complex solutions that are used for patient monitoring and analysis of special questions on the other hand||3.355|

|50||Interior furnishing||The main group structure in segment 50 is divided by the room of the house (e.g. living room) the furnishing belongs to. On the group level, the type of furniture (e.g. cupboard) is stated and on the subgroup level it is specified (e.g. cupboard, lowboard, sideboard highboard. The segment comprises of nine main groups that are far developed going deeper into the structure.||494|
|51||Fluid power||Starting from ECLASS Release 11.0, the two former main groups 27-29 Pneumatics and 27-30 Hydraulics were merged into this segment. Therefore, main groups 51-01 to 51-09 are filled with with pneumatics content such as actuators, valves, compressed air preparation, vaccuum technology and pneumatic connection technology, while main groups 51-41 to 51-57 are filled with hydraulics content such as pumps, motors, transmissions, power units and hydraulic accumulators.||914|
|90||Interim class (unspecified)||The interim class is used for structural content that has to be stored in order to move it to another existing segment, for restructuring purposes and for development of new segments under a nwe expert group. Groups (3rd level) for objects that cannot be classified into other specified groups in the existing structure, but that are classified to their parent-class on the 2nd level. A xx-xx-90-00-class cannot have any other sub-groups besides the generic xx-xx-90-90-class (…(Other, unspecified)) to be generally valid within the parent class on the 2nd level. Subgroups (4th level) for objects that cannot be classified into other specified subgroups in the existing structure, but that are classified to their parent-class on the 3rd level.||4|
Main groups on the second level and groups on the third level further devide product classes into more specific sub-groups.
The 8-digit class code (in ECLASS called: CodedName) consists of two digits for each of the four hierarchical levels. It is an arbitrary number and indicates where in the classification tree a product class is to be found. In contrast to the usual arbitrariness of classification codes, the ECLASS classification system uses certain specific class codes that have a meaning. They are called descriptive codes and they all begin with 9x. In contrast to the "quick guide for ECLASS-change requests" only the following descriptive codes are still being used in the ECLASS classification system:
Each main group (classification class on the 2nd level, e.g. 21-01-00-00) consists of at least the 90-class on the 3rd level, e.g. 21-01-90-00. The 90-class is the collective group for products that, following extensive checks, cannot be classified into other existing groups.
NOTE: Starting with ECLASS release 8.0 xx-xx-90-00-classes will
- only contain one generic sub-group xx-xx-90-90 ("Other, unspecified", see below). I.e. no xx-xx-90-01-classes will be allowed any more. This is planned to be corrected in MajorRelease 9.0.
All xx-xx-90-00-classes are described by the following generic definition:
Group (3rd level) for objects that cannot be classified into other specified groups in the existing structure, but that are classified to their parent-class on the 2nd level. A xx-xx-90-00-class cannot have any other sub-groups besides the generic xx-xx-90-90-class (…(Other, unspecified)) to be generally valid within the parent class on the 2nd level
Each group (classification class on the 3rd level, e.g. 21-01-01-00) consists of at least the 90-class on the 4th level, e.g. 21-01-01-90. The 90-class is the collective subgroup for products that, following extensive checks, cannot be classified into existing subgroups.
NOTE: Starting with ECLASS release 8.0 90-classes will
- be renamed to (unspecified) as they are classified, but not further specified with the help of keywords or properties. I.e. they will be named as the parent class on the 3rd level plus (unspecified), e.g. 21010100 Knurling tool; 21010190 Knurling tool (unspecified).
- only exist on the 4th level
- do no longer contain keywords
- do no longer contain properties apart from the basic property list, i.e. they are no longer described with properties that describe the product itself
All 90-classes are described by the following generic definition, note and remark:
Sub-group (4th level) for objects that cannot be classified into other specified sub-groups in the existing structure, but that are classified to their parent-class on the 3rd level
A 90-class is not further specified with the help of properties (apart from the basic properties) nor keywords in order to be universally valid within its parent-class on the 3rd level.
Assignments of products and services on a 90-class could be an indication that a more specified class structure is necessary and should therefore be requested.
It is planned to create the 90-class on the 4th level automatically when creating a new classification class on the 3rd level (group).
91-classes describe objects with spare part characteristics, without which the basic function of the product is not guaranteed.
NOTE: Starting with ECLASS release 8.0 91-classes will
- only exist on the 4th level
- be named as the parent class on the 3rd level plus (parts), e.g. 21010100 Knurling tool; 21010191 Knurling tool (parts)
- do no longer contain properties that describe the product itself, but only to identify the spare part or its relation to the product that the part is used for. This is to avoid that a certain product can be described as a distinct product class and as a parts-class for another parent product
All 91-classes are described by the following generic definition and note:
Sub-group (4th level) for objects with spare part characteristics that maintain or restore the original condition of the objects classified under the parent-class on the 3rd level
The determination of the appropriate (spare) part (e.g. notebook display) takes place with the help of the name of the complete object that is to be maintained (e.g. notebook).
92-classes describe objects with "add-on" characteristics, without which the basic function of the product is still guaranteed.
NOTE: Starting with ECLASS release 8.0 92-classes will
- only exist on the 4th level
- be named as the parent class on the 3rd level plus (accessories), e.g. 21010100 Knurling tool; 21010192 Knurling tool (accessories)
All 92-classes are described by the following generic definition:
Sub-group (4th level) for objects with complemental characteristics, without which the basic function of the objects classified under the parent-class on the 3rd level is still guaranteed
ECLASS has blocked the class codes 98 and 99 on all levels for company-specific use (see also: the blocked segments 98-00-00-00 and 99-00-00-00), i.e. ECLASS will not use these class codes on any level. A company may use them for internal purposes where needed.
- NOTE: We advice to not exhange these data with business partners as they might have used the same codes for their internal purposes and assigned them to different product groups.
- EXAMPLE: In segment 20 Packing material, a company might need to assign class codes to company-specific products that cannot be classified in ECLASS. A new ECLASS-class is not requested either as it is not needed. A company may now use a new main group 20-98-00-00 to create the new structure 20-98-01-01 for their own purposes, as well as 20-03-98-01 or 20-03-01-98. This way, a new struture on all hierarchical levels is possible in any existing segment.
|Descriptive Code||Hierarchy||PreferredName||Properties||Keywords allowed|
|90-classes||Only on 4th level (exception for 90-90)||Preferred Name of the 3rd level plus (unspecified)||No properties allowed apart from basic properties||No|
|91-classes||Only on 4th level||Preferred Name of the 3rd level plus (parts)||Properties restricted (i.e. BAF281)||Yes|
|92-classes||Only on 4th level||Preferred Name of the 3rd level plus (accessories)||Properties allowed||Yes|
|98-classes||All levels (1-4)||Company-specific||No restrictions||No restrictions|
|99-classes||All levels (1-4)||Company-specific||No restrictions||No restrictions|
The following part will describe how the structural element "classification class" is structured and what attributes it consists of. All attributes are named in CamelCase writing. Attributes can be mandatory or optional, can be created automatically or manually be the user and underly certain rules. All of them are limited to a certain amount of characters.
The official and internationally unique ECLASS identifier, i.e. primary key, is the IRDI (International Registration Data Identifier), a globally unambiguous identifier that comprises Supplier+TypeOfSE+Identifier+VersionNumber. The separate export of Supplier, ID, VersionNumber and the Identifier (ID+ VersionNumber) is therefore redundant. Starting with ECLASS Release 8.0 this redundant information will no longer be additionally exported, because it is already contained in the IRDI which is the only valid primary key in ECLASS.
The identifier for classification classes is the IrdiCC. It is mandatory, automatically created and limited to 20 characters. TheTypeOfSE of a class is 01.
See Class code (coded name), the attribute is called CodedName and is a mandatory field.
The text attribute named PreferredName is the official name of the product class and is a mandatory text field. The following rules apply to the PreferredName:
- 80 character limit
- is a unique name, i.e. does not exist more than once in the ECLASS classification system
- Begins with a capital Letter in any language where capital letters exist
- no special characters allowed
- Must not contain a trademark, company or brand name
- It should be possible to use the preferred name within a continuous text , i.e.
- Adjective before noun (German, English)
- Lower case for adjectives
- Avoid combinations of several terms, keywords/synonyms are denoted separately
- Give preference where possible to the basic grammatical form (singular, infinitive)
- The following special characters must be avoided: semicolons (;), inverted commas (")
- Do not use additions which resemble properties
Today, the class definition is a mandatory text field. The objectives and rules are described below.
- Objective 1: a class definition shall describe the product class and give more information in order to make it easier for
- Quality check
- Users to find their product group
- Translators to find the right terminology
- Users of other standards to map/match/harmonize
- Objective 2: The quality check of definitions shall be content-oriented, less form-oriented.
- Objective 3: From 1st to 4th level the definition shall go from general to specific.
- Objective 4: The definition shall deliver details what kind of products are to be found in the class.
- Objective 5: Every class (all levels) in ECLASS shall have a definition with release 8.0 latest.
- 1023 character limit
- no special characters allowed
- formal rules must be considered:
- start without a definite or indefinite article
- start with a lower case letter (unless it is a German noun)
- do not end with a full stop or any mark
- A definition shall deliver information on
- how and why the class is distinguished from its neighboring classes (i.e. distinction criteria of neighborhood)
- how and why the class is distinguished from other related classes (i.e. distinction criteria of similar classes in other segments).
- A segment’s definition shall describe the segment and what is generally included (branch, market etc.).
- A definition of a segment, main group and group shall describe the classification criteria of their sub-groups, i.e. describe how the sub-groups, i.e. subordinate class levels are distinguished from each other (e.g. by material, application, area, etc.).
- Descriptive codes have a generic (maybe automatically created) definition (and note, remark where available), see above.
Note on definition, optional, created by user, limited to 1023 characters.
Remark on usage of the class, optional, created by user, limited to 1023 characters.
