The Harmonized Commodity Description and Coding System, or Harmonized System (HS), is designed by the World Customs Organization (WCO) as a multi-purpose classification system of commodities suitable for use by customs and statistical authorities, importers/exporters, carriers and others involved in international merchandise trade. Hong Kong has adopted the HS in full for trade declaration purposes since 1 January 1992.
The HS designed by the WCO is a hierarchical system of commodity classification and coding. Each commodity is identified by a 6-digit HS code, in which the first 2 digits denote the "chapter" in the HS under which the commodity is classified, the first 4 digits denote the "heading" and the whole 6 digits denote the "subheading". For example, hens are classified in subheading 0105 94 "fowls of the species Gallus domesticus", which is under heading 0105 "live poultry" in Chapter 1 "live animals".
|HKHS 2022 Edition||Section||Chapter||Heading||Subheading||Item|
|No. of Categories||22||97||1 299||5 613||7 802|
Each year, updating of the HKHS is made by the Census and Statistics Department (C&SD) to take account of significant changes in trade pattern and technology, and local and international requirements. Apart from the regular annual updating, the HKHS will undergo major updating every 5 years to incorporate the WCO's recommended amendments to the HS in its major revision.
Previous editions of HKHS and the corresponding correlation tables are also available on this website.
