Cyanide is 711, metal liquids 721 to 728, PCB liquid 731 & halogenated organics 741 & 751. Strong acids are 791 & 792.

Which California codes cover restricted waste?

Liquid entries use mg/L. Code 751 covers halogenated solids and sludge, and its numerical entry uses mg/kg.

The codes are 711, 721, 722, 723, 724, 725, 726, 727, 728, 731, 741, 751, 791, 792 and 801.

How do you tell California restricted waste codes apart?

These are thresholds for choosing a code, not limits for hazardous status. The code pages show the exact boundaries and any published conflicts.

What can change the route for California restricted waste?

A result exactly at the numerical limit qualifies for each restricted concentration entry. The 2017 DTSC handout prints different boundaries for several codes, and the code pages it affects show both descriptions.

The classification and shipping rules still apply.
