About the Section

Chinese liquor samples
Chinese liquor samples

The Section provides analytical and advisory support to the Customs and Excise Department (C&ED) in the enforcement of legislation concerning revenue collection and consumer protection. Analytical services are provided to support their statutory functions under various regulations and ordinances. Samples of government purchases are also sent to this section by the Government Logistics Department for determining whether the products are in compliance with tender specifications. Testing services on miscellaneous commodities such as flexible gas tubing and parts of endangered species are also provided to various government departments.

A wide variety of dutiable commodities such as spirits, liquors, cigarettes & cigars, manufactured tobacco, diesel fuels and petrol are analysed for duty assessment under the Dutiable Commodities Ordinance. Tar and nicotine yields of about a hundred brands of cigarettes marketed in Hong Kong are routinely monitored for implementation of a cigarette testing programme, which is devised in accordance with Smoking (Public Health) Ordinance to provide enforcement authority and the public with updated information on tar and nicotine yields of cigarettes on sale in Hong Kong. Verification for compliance with Weights and Measures Ordinance is performed on a variety of measuring equipment and pre-packed goods. Toys and children's products are tested against safety standards prescribed in Toys and Children's Products Safety Ordinance while other consumer goods are tested for compliance with Consumer Goods Safety Ordinance.


Responsibilities

This Section helps to implement the following Ordinances of Hong Kong:

  • Dutiable Commodities Ordinance and subsidiary Regulations
  • Smoking (Public Health) Ordinance and subsidiary Regulations
  • Weights and Measures Ordinance
  • Toys and Children's Products Safety Ordinance and subsidiary Regulation
  • Consumer Goods Safety Ordinance and subsidiary Regulation

Targets and Key Indicators

Key Performance Measures Relating to the Statutory Testing

Targets #

Testing Targets 2016
(Actual)
2017
(Actual)
2018
(Plan)
Dutiable and other commodities within reporting time averaging 10 working days (%) 95 99 100 95
Toys and children's products within reporting time averaging 15 working days (%) 95 99 99 95
Consumer goods within reporting time averaging 35 working days (%) 95 99 100 95

For targets where reporting time is mentioned, different samples require different analytical procedures, hence different reporting time. The quoted number of working days required represents an average of reporting time for the different types of samples and test requests within the category, while the target (in percentage) is the total compliance rate of the concerned samples and test requests within a particular category against their respective targets.
