ERG 2024 lists UN/NA 2681 (Caesium hydroxide, solution) under Guide 154, titled “Substances - Toxic and/or Corrosive (Non-Combustible)”.
Material name
2681 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Caesium hydroxide, solution” and “Cesium hydroxide, solution”. Both use Guide 154, so the number alone is enough to find the guide. On a numbered orange panel, 2681 is the lower number (how to read an orange panel).
