In an effort to increase transparency and to facilitate access to information on substances in Canadian commerce, the Government of Canada is publishing a summary of the information received in response to the Notice with respect to perfluorohexane sulfonic acid, its salts and its precursors (PFHxS). The notice was published on October 10, 2020 in the Canada Gazette, Part I, pursuant to paragraph 71(1)(b) of the Canadian Environmental Protection Act, 1999 (CEPA). The initiative collected information on perfluorohexane sulfonic acid, its salts and its precursors (PFHxS) for the purposes of assessing whether to control, or the manner in which to control, the risks posed by these substances.
The notice required manufacturers, importers, exporters and those who used PFHxS in the manufacture of a mixture, product or manufactured item to report commercial quantities and use patterns, including mixtures, products and manufactured items containing these substances. Since this initiative targeted information to address specific data needs for PFHxS, the information gathered and reported here may not represent the entire range of commercial activities in Canada for these substances. When reviewing the summary of responses received, it is important to consider:
• the definitions applicable to the notice,
• the persons required to provide information,
• the exclusions; and,
• the reporting requirements.
