Organic liquid with listed metals
Hazardous organic liquid containing a metal listed in code 121.
Is California code 342 hazardous waste?
Not from the code alone. Waste must first be found hazardous. Code 342 isn't a restricted code, but a restricted category that fits takes priority over it. A code that isn't restricted doesn't make waste non-hazardous.
When a shipment needs the Uniform Hazardous Waste Manifest, enter 342 in Item 13 for the waste line. Use one California code, plus the federal RCRA codes when the waste is federally hazardous.
RCRA waste meets a federal listing or characteristic, with no federal exclusion that applies. Non-RCRA waste is hazardous under California rules only. California presumes hazardous waste is RCRA unless the generator shows it isn't, so keep that determination.
What does California code 342 cover?
This code is for hazardous organic liquid holding one of the metals under code 121. Form and makeup limit it. Water-based liquids use another code, and a restricted metal threshold that matches takes priority.

Is metal-bearing liquid California code 342, 132 or 341?
| Code | When it fits |
|---|---|
| 342 | A listed metal is present in hazardous organic liquid and no matching restricted threshold is met. |
| 132 | A listed metal is present in hazardous water-based liquid instead. |
| 341 | The organic liquid is also halogenated non-solvent material and code 741 does not apply. |
| California restricted code 721–728 | The corresponding metal in liquid reaches its restricted-code threshold. |
A matching restricted code wins. If a non-solvent organic liquid holds both a listed metal and halogens, the regulations don't say which of 342 and 341 wins.
