ERG 2024 lists UN/NA 2657 (Selenium disulfide) under Guide 153, titled “Substances - Toxic and/or Corrosive (Combustible)”.
Material name
2657 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Selenium disulfide” and “Selenium disulphide”. Both use Guide 153, so the number alone is enough to find the guide. On a numbered orange panel, 2657 is the lower number (how to read an orange panel).
ERG 2024 markings for 2657
2657 is not highlighted in green (no Table 1 entry), and its guide number 153 has no P.
