Spent solvent: 5 codes.
Spent solvent
HOCs means halogenated organic compounds. Check the restricted concentration before choosing by chemistry; see solvent composition and concentration rules.

| Code | When it fits |
|---|---|
| 741 | Total HOC concentration in liquid |
| 211 | The solvent contains chlorine, fluorine, bromine or iodine |
| 212 | The solvent contains oxygen, as in acetone or butanol |

How do you check halogenated solvent concentration in California?
HOCs are halogenated organic compounds. Measure their total concentration in the liquid, not just the main solvent.
At 1,000 mg/L or more, use restricted code 741 before any general solvent or organic-liquid entry. Below that limit, a halogenated solvent can use 211.
Don't assign 211 from the solvent name alone.
What do California spent solvent chemistry names mean?
Halogenated compounds contain chlorine, fluorine, bromine or iodine. Oxygenated solvents include acetone and butanol. Hydrocarbon solvents contain only carbon and hydrogen.
These are composition groups, not brand names.
