ERG 2024 lists UN/NA 2509 (Potassium hydrogen sulfate) under Guide 154, titled “Substances - Toxic and/or Corrosive (Non-Combustible)”.
Material name
2509 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Potassium hydrogen sulfate” and “Potassium hydrogen sulphate”. Both use Guide 154, so the number alone is enough to find the guide. On a numbered orange panel, 2509 is the lower number (how to read an orange panel).
ERG 2024 markings for 2509
2509 is not highlighted in green (no Table 1 entry), and its guide number 154 has no P.
