National Classifications

Korean Standard Industrial Classification

Country / Area: Korea, Republic of

Classification category: Activity classifications

General information
1 (a)Name of the current national classification (full name in official national languages and in English with acronyms in brackets, should be given)Korean Standard Industrial Classification (KSIC)
1 (b)In which language(s) is the classification available?Korean and English (numerical list of titles)
1 (c)Can the classification (or information about it) be accessed on the Internet? If yes, please provide the URL.http://kostat.go.kr/kssc
Classification structure
2 (a)Please describe the structure of the classification: How many levels does the classification have? (Please provide labels, such as “Division”, “Class”) How many categories exist at each level?The KSIC which is based on the International Standard Industrial Classification of All Economic Activities (ISIC) is a hierarchical five digit system. KSIC is divided into 21 sections and each section is denoted by a single letter from A to U. The letters of the sections can be defined by the next breakdown, the divisions (denoted by 2 digits). The divisions are then broken down into groups (3 digits), into classes (4 digits) and then into subclasses (5 digits). There are 76 divisions, 228 groups, 487 classes and 1,145 subclasses.
2 (b)Please provide examples of the coding system used at each level.Section C Manufacturing (Comprising divisions 10 to 33)
Division 22 Manufacture of Rubber and Plastic Products
Group 221 Manufacture of Rubber Products
Class 2211 Manufacture of Rubber Tires and Tubes; Rebuilding of Rubber Tires
Subclass 22111 Manufacture of Tires and Tubes
Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.KSIC, Rev. 9 was revised, based on ISIC, Rev. 4
3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)To the four digit level, the structure of KSIC (Rev. 9) is very similar to that of ISIC (Rev. 4). However, a fifth digit has been added and the classification categories and code numbers have been adapted to reflect the Korean circumstances. For example, ISIC division 29, manufacture of motor vehicles, trailers and semi-trailers = KSIC division 30, manufacture of motor vehicles, trailers and semitrailers while ISIC class 2930 (manufacture of parts and accessories for motor vehicles) = KSIC class 3031, manufacture of parts and accessories for motors engines +3032, manufacture of parts and accessories for motor vehicle body +3039, manufacture of other parts and accessories for motor vehicles.
3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.The structure of KSIC has been created by being divided, integrated and regrouped on the basis of ISIC. For instance, ISIC, Rev. 4 provides separate categories for the repair of all kinds of goods while no single high-level category exists that would cover all repair activities. Based on the type of good repaired, the activities are classified as follows:
Repair of motor vehicles and of motorcycles = classes 4520 and 4540
Repair of computers and communication equipment = group 951
Repair of personal and household goods = group 331

However, KSIC, Rev. 9 has a high-level category for the repair of all kinds of goods (95 division /maintenance and repair service). The detailed group information is as follows:
Repair of Maintenance and repair service of machinery and equipment = group 951
Maintenance and repair services of motor vehicles and motorcycles = group 952
Repair services of personal and household goods = group 953

3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)For the survey of business activities, KOSTAT collect, compile and publish data at 2-digit KSIC level. For international comparison, data can be adapted according to the correspondence table between KSIC, Rev.9 and ISIC, Rev.4.
3 (e)If no links to international classifications exist or no international standard is used, please state if there are plans to use international norms in the future. 
Classification uses
4 (a)Please state for which statistical purposes (surveys etc.) this classification is used and if there are users outside of the Statistical Office. Please indicate at which level the classification is used for data collection and for data publishing.In Korea, KSIC, Rev.9 should be used for producing official statistics. So research institutions and public corporations as well as central government agencies and local governments use KSIC to collect data. KSIC level for data collection differs depending on surveys but usually data are collected at 3-digit KSIC level and published at 2-digit KSIC level.
4 (b)Please give the names of institutions that use the classification for non-statistical purposes (as opposed to statistical purposes in question 4(a)). Also indicate the kind of use (e.g. tax offices, social security, customs, enterprise register, employment services, work permits etc.)KSIC, Rev.9 is used by the following organizations: the Small and Medium Business Administration, Public Procurement Service, Tax Offices, enterprise register etc.
4 (c)Please indicate if alternative classifications are used by other institutions of the economy. Are these classifications available and useful for the Statistical Office? 
Implementation / revision status
5 (a)Please state the date of the official adoption of the classification. If not yet adopted, please indicate the current state (e.g. in development, sent for approval, in printing, ready to be distributed etc.)The classification was adopted in 1963. KSIC, Rev.9 was revised in December 2007 and came into force on 2 February 2008.
5 (b)Please state the date of use of the classification for individual statistical programmes. 
5 (c)Are there existing plans for revision or update of the current classification?KOSTAT is considering the revision of KSIC, Rev.9 on the basis of the results of 2010 Population and Housing Census and 2011 Economic Census and the opinions of private sectors. The commencement of the work will probably be in the second half of next year.
5 (d)Name of former (previous) national classification (full name in both national tongue and in English with acronyms in brackets, should be given)The name, Korean Standard Industrial Classification (KSIC) has not been changed.
5 (e)Please describe the link of the former classification to international classificationsKSIC, Rev.8 was revised, based on ISIC, Rev.3.
5 (f)Please describe the structure of the former classification and indicate the number of items at each level of the classification. (similar to question 2(a))KSIC Rev.8 is divided into 20 sections, each represented by a single letter from A to T. The sections are divided into two-digit divisions. The divisions are then broken down into groups (3 digits), then into classes (4 digits) and into subclasses (5 digits). There are 63 divisions, 194 groups, 442 classes and 1,121 subclasses.
5 (g)Do conversion tables exist between the former and current classification?Yes.
