On March 24, 2022, the Taiwan Environmental Protection Administration released an explanatory note on the labeling of “hydrogen fluoride,” which is a chemical substance of concern. Article 3 of the “Toxic Chemical Substances Labeling and Materials Safety Data Sheets Regulations” specifies that the name published by the central authority for the chemical substance of concern shall be displayed (in Chinese and English). With regard to “hydrogen fluoride,” since there are multiple names, this note was published to clarify which names should be displayed. According to the Environmental Protection Administration, one or both of “氟化氫” or “氫氟酸” may be displayed in Chinese, and either “Hydrogen fluoride,” “Hydrofluoric acid” or “Fluorhydric acid” satisfy the specified conditions.
Relevant provisions for “hydrogen fluoride”
On August 20, 2021, the Environmental Protection Administration announced the addition of “hydrogen fluoride” to the chemical substances of concern. Based on the relevant regulations, from August 1, 2022, containers, packaging, handling locations, and facilities for “hydrogen fluoride” must indicate the regulated items and an SDS must be prepared. Note that the items that must be indicated differ depending on the content of “hydrogen fluoride,” as described below.
- If the content of hydrogen fluoride is 0.1% or more and less than 10% of the regulated concentration, it is only necessary to display the indication on containers and packaging in accordance with the provisions of the “Toxic Chemical Substances Labeling and Materials Safety Data Sheets Regulations.”
- If the concentration is 10% or more, it is necessary to apply for approval documents in accordance with the provisions of the “Toxic and Chemical Substances of Concern Control Act.”
