2031 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Nitric acid, other than red fuming, with more than 65% nitric acid” and “Nitric acid, other than red fuming, with not more than 65% nitric acid”. Both use Guide 157, so the number alone is enough to find the guide. On a numbered orange panel, 2031 is the lower number (how to read an orange panel).
