Strategic Trade Controls Circular No. 16/04

Import and Export Control on Chemicals,Biological Agents and Dual-Use Facilities and Equipment
Related to the Manufacture of Chemical and Biological Weapons

          This circular serves to update traders on the licensing requirement for certain strategic commodities including chemicals, biological agents and dual-use facilities and equipment related to the manufacture of chemical and biological weapons. The Strategic Trade Controls Circular No. 2/01 dated 1 March 2001 on the same subject is hereby superseded.


2.        Under Import and Export Ordinance, Chapter 60, Laws of Hong Kong and its subsidiary legislation i.e. Import and Export (Strategic Commodities) Regulations ("the Regulations"), import and export of certain chemicals, biological agents as well as dual-use facilities and equipment related to the manufacture of chemical and biological weapons, and transit of articles which are for a use relating to chemical and biological weapons, must be covered by valid licences issued by the Director-General of Trade and Industry. These products are listed in Schedules 1, 2, 3 and 4 to the Regulations and are regarded as strategic commodities and therefore subject to licensing requirement.


3.       Schedule 1 to the Regulations comprises two lists of products: the Dual-use Goods List and the Munitions List. The two lists have included the items under the control lists of two international control regimes - the Australia Group (AG) which aims to minimize the risk of chemical and biological weapons proliferation; and the Chemical Weapons Convention (CWC) which aims to prohibit the development, production, stockpiling and use of chemical weapons and on their destruction. Such items mainly fall under the following categories:
  1. Chemicals (Annex A) (pdf format)-
    Dual-use Goods List: Categories 1C350 and 1C450
    Munitions List: Categories ML7(b), ML7(c)
  2. Biological Agents (Annex B) (pdf format)-
    Dual-use Goods List: Categories 1C351, 1C353 and 1C354
  3. Dual-use Facilities and Equipment related to
    Chemical and Biological Weapons (Annex C) (pdf format) -
    Dual-use Goods List: Categories 2B350, 2B351, 2B352 and 9A350
4.       Schedule 2 to the Regulations contains products which, in addition to being subject to import and export controls, are also controlled even if they are in transit through Hong Kong (see paragraphs 15 - 16). Schedule 3 and 4 are items and activities subject to end-use controls (see paragraph 17).


A. Application Forms

Paper Applications

5.        Licence applications for import and export of strategic commodities listed in Annexes A (pdf format), B (pdf format) and C  (pdf format) should be made on Import Licence (Strategic Commodities) Application Form [TID 501] and Export Licence (Strategic Commodities) Application Form [TID 502]. These paper forms are available free of charge at the Integrated Customer Service Centre (at Room 1324, 13/F, Trade and Industry Tower, 3 Concorde Road, Kowloon City, Hong Kong).

They can also be downloaded from the Chemical Weapons (Convention) Ordinance Website ("the CWC Website") at Please visit the CWC Website for details and the latest updates of the import/export licensing requirement for chemicals as well as the Chemical Permit and Notification System in relation to activities involving chemicals subject to the Chemical Weapons (Convention) Ordinance.


12.        If licence applications are approved, regardless of whether the applications are made in paper or electronic format, only paper licences will be issued. Under normal circumstances, applications duly completed and supported by all the documents required will be processed within 2.5 clear working days after the date of submission of the licence applications. However, for cases with complications or if additional documents/information are necessary, longer time may be required to process the applications. Other government departments may also be consulted as and when necessary on a case-by-case basis. To check whether their applications have been processed and are ready for collection, applicants can visit the SC Website. Applicants are advised to submit their applications well in advance of the shipments.

13.       To collect the approved licence copies, paper licence applicants can present the receipt issued to them upon licence submission to the Integrated Customer Service Centre (at Room 1324, 13/F, Trade and Industry Department Tower). For applicants of electronic licence applications, they can follow the instructions upon successful submission of E-Applications to print out the receipt for subsequent collection of the approved licences at the Integrated Customer Service Centre. Approved import and export licences are valid for six months and three months respectively.


14.       At the time of receiving the approved licences, applicants should read the part, "Licence Conditions", regarding the use of the licence. One of the special licence conditions for licences covering products for local resale/transfer/disposal is "Prior notice to and approval from the Department may be required if the goods are intended for further resale/transfer/disposal". Licensees imposed with this condition should submit to the Integrated Customer Service Centre designated form SC047 (Annex M) (fillable pdf format) to request for approval of resale/transfer/disposal of their products. Supporting documents including original trader/end-user undertakings completed by the proposed recipient and end-user, valid export permit/authorisation issued by the originating or exporting country/place of the product giving approval to the proposed resale/transfer, must also be submitted. The Department will give due consideration to the application and notify the licensee in writing of its decision. Only after receipt of Trade and Industry Department's written approval should the licensees proceed with the resale/transfer/disposal of the goods. Otherwise, the licensee would have breached the above licence condition.


15.     When applying for licences for goods in transit, apart from adhering to the requirements as stated in paragraphs 5 - 10 as appropriate, applicants should also:
  1. submit both import and export licence applications together to the Trade and Industry Department; and
  2. declare on the licence applications that the goods are in transit, and state the transport mode, name of the vessel or flight number, and expected arrival and departure dates. For E-Applicants, tailor-made declaration for this purpose is available for selection at Part I "Preparation of Declaration Lists" of the E-Import Licence Application menu.
16.      Exporter may also be required to provide a landing certificate or delivery verification certificate issued by the country/place of destination to the Department within 12 weeks after the date of shipment.


17.      The Regulations also impose licensing requirement on articles specified in Schedule 3 to the Regulations (Annex N) (pdf format), or any technological document containing information relating to any such article:
  1. if the importer/exporter knows that the article or document is intended or likely to be used in any activity related to nuclear, chemical or biological weapons or missiles capable of delivering them as specified in Schedule 4 to the Regulations (Annex O) (pdf format); or
  2. if the importer/exporter has grounds for suspecting that the article or document may be used in any activity specified in Schedule 4.


18.      Section 6A of the Import and Export Ordinance stipulates that no person shall import or export any article specified in the Schedules to the Regulations except under and in accordance with a licence issued by the Director-General of Trade and Industry. Any person who contravenes this provision shall be guilty of an offence and is liable:
  1. on summary conviction to a fine of HK$500,000 and to imprisonment for two years; and
  2. on conviction on indictment to an unlimited fine and to imprisonment for seven years.
