ERG 2024 lists UN/NA 1789 (Hydrochloric acid) under Guide 157, titled “Substances - Toxic and/or Corrosive (Non-Combustible/Water-Sensitive)”.
Material name
1789 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Hydrochloric acid” and “Muriatic acid”. Both use Guide 157, so the number alone is enough to find the guide. On a numbered orange panel, 1789 is the lower number (how to read an orange panel).
