National Classifications

工業產品、加工/服務分類表 / Industrial Product and Work/Service List

Country / Area: China, Hong Kong SAR

Classification category: Product 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)Chinese: 工業產品、加工/服務分類表
English: Industrial Product and Work/Service List (IPWS)
- Classification of industrial goods and services adopted in Census and Statistics Department’s (C&SD) economic surveys.
1 (b)In which language(s) is the classification available?Chinese and English
1 (c)Can the classification (or information about it) be accessed on the Internet? If yes, please provide the URL.Detailed Information on the products and services is provided to respondents during data collection. In the case of IPWS, information on the compilation methodology of the producer price index for the industrial sector is available in the relevant survey report which is available online.
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?4 levels including (a) 5 Sections (1-digit), (b) 27 Divisions (2-digit), (c) 174 Classes (4-digit) and (d) 693 Sub-classes (7-digit). IPWS adopts a seven-digit system. The first digit is the first digit of Central Product Classification (CPC) Ver. 2. The second to fifth digits correspond to the four-digit industry group code of the Hong Kong Standard Industrial Classification (HSIC) Ver. 2.0. The sixth to the seventh digits are locally developed codes for classifying industrial goods and industrial services products.
2 (b)Please provide examples of the coding system used at each level.Fresh milk, pasteurized or homogenised
Section: 2 (Food products, beverages and tobacco; textiles, apparel and leather products) [CPC Ver. 2.0 section code]
Division: 10 (Food products) [HSIC Ver. 2.0 industry code]
Class: 1050 (Manufacture of dairy products) [HSIC Ver. 2.0 industry code]
Subclass: 2105001
Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.IPWS is linked to CPC Ver. 2. The first digit of IPWS corresponds to the first digit code of CPC Ver. 2;
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)IPWS’s structure has three levels while CPC Ver. 2 has five levels (section, division, group, class and subclass). While the first-digit corresponds to the Section level of CPC Ver. 2, the Division and Class levels correspond to HSIC Ver 2.0 which follows ISIC Rev. 4. The IPWS List is used mainly for compiling producer prices of the industrial sector. Since the contribution of the industrial sector to gross domestic
product in Hong Kong is small, the IPWS List is rather simple with few breakdowns.
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.Please refer to the response at 3(b).
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.)The first-digit corresponds to the Section level of CPC Ver. 2.
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.Not applicable.
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.

Enumerated data are classified by seven-digit code. Owing to sample size limitations, product statistics are not generally published. Statistics at broad industry level (based on aggregated product statistics) are released to the public. Product statistics may be compiled and released on request basis, subject to reliability
considerations and ensuring confidentiality of data provided by individual establishments.
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.)Not applicable.
