1835 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Tetramethylammonium hydroxide aqueous solution with more than 2.5% but less than 25% tetramethylammonium hydroxide” and “Tetramethylammonium hydroxide, solution”. Both use Guide 153, so the number alone is enough to find the guide. On a numbered orange panel, 1835 is the lower number (how to read an orange panel).
