Taiwan CLA is taking the lead in developing a national chemical inventory for Taiwan’s stage-wise GHS implementation. So far, all the three batches of 3,171 hazardous substances subject to the first, second and third stage respectively have been released.

Taiwan adopted GHS on 31 Dec of 2008 when the first stage of GHS was implemented, which only covers 1,062 hazardous substances designated according the Point 1 of Article 2 of the Regulation. The second stage of GHS implementation was initiated on 7 Jan, 2011, covering 1,089 substances. The 1,020 hazardous substances are applicable to the third stage of Taiwan GHS implementation on 1 Jan, 2014. These two batches of hazardous substance are designated according to the Point 2 above. All the three batches are respectively given with one-year transitional period.

Other hazardous chemicals besides the 3,171 substances designated by the CLA, if found falling in the scope of the Regulation, should also comply with Taiwan GHS since 1 Jan 2016 while granted with a one-year transitional period due by 31 Dec 2016.
