This update was formally notified to the TBT Committee of the WTO on December 10, 2024.

Key Revisions:

  1. Expanded Signal Words: Both long- and short-form warnings may now use additional signal words, such as “CA WARNING” or “CALIFORNIA WARNING,” in addition to the current signal word “WARNING”.
  2. Chemical Identification Requirement: Short-form warnings must now specify at least one chemical name.
  3. Font Restrictions Updated: The previous rule requiring the short-form warning font to be no smaller than the largest type size used for other consumer information. has been lifted. However, a minimum font size of 6-point remains in effect.
  4. Application to Food Products: Short-form warnings are now explicitly permitted on food product labels.
  5. Online Retail Transition Period: A 60-day transition window is established during the three-year implementation phase, allowing internet retailers to update online short-form warnings after receiving notice from manufacturers.
