Hazardous Chemicals Control Ordinance

The Hazardous Chemicals Control Ordinance (HCCO) (Cap.595) aims to regulate, through an activity-based permit system, the import, export, manufacture and use of non-pesticide hazardous chemicals that have potentially harmful or adverse effects on human health or the environment. At present, the non-pesticide hazardous chemicals under the HCCO include such chemicals that are subject to regulation of the Stockholm Convention on Persistent Organic Pollutants or the Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade.
Details of Cap.595 and its subsidiary regulations can be found at the "Bilingual Laws Information System" website of the Department of Justice at this link. 

Permit holders are required to report the controlled activities regularly. “Activity Report Forms” can be downloaded here.
