## Is D005 hazardous waste?

**Yes.** Waste is D005 when the TCLP extract of a representative sample holds barium at or above 100 mg/L. That makes it toxic hazardous waste, whatever industry or process it came from.

Compare the barium in the TCLP extract with 100 mg/L. A total barium result is a different measure, so it can't be compared with this limit.

D005 is a nonacute characteristic. On a required [hazardous waste manifest](https://complyonsite.com/tools/hazardous-waste-manifest), put D005 in Item 13. See [VSQG exemptions and empty-container rules](https://complyonsite.com/tools/rcra-waste-codes?list=routes).

## What does D005 cover?

D005 applies when a representative sample gives a TCLP extract with barium at or above 100 mg/L. The limit is for the extract, not the waste’s total barium.

- **CAS**: 7440-39-3
- **Regulatory level**: 100 mg/L in TCLP extract
- **Hazard**: T, toxic
- **Rule**: [40 CFR 261.24](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-261/section-261.24)

## Is barium waste always D005?

| Code | When it fits |
| --- | --- |
| D005 | The TCLP extract of a representative sample holds barium at or above 100 mg/L. |
| [D004–D043](https://complyonsite.com/tools/rcra-waste-codes?list=toxicity) | The barium result is below 100 mg/L, but another contaminant or characteristic can still apply. |

Generators decide the codes from testing or knowledge of the waste, under 40 CFR 262.11. A result below 100 mg/L rules out D005 only. It doesn't make the waste nonhazardous.

## Which wastes take D005?

| Waste | When it’s D005 |
| --- | --- |
| [Waste contaminated with toxic metals](https://complyonsite.com/tools/rcra-waste-codes?waste=metal-contaminated-waste) | Its barium leaches at the TCLP limit or above. |
| Barium-contaminated waste | Its barium leaches at the TCLP limit or above. |
| [Contaminated soil](https://complyonsite.com/tools/rcra-waste-codes?waste=contaminated-soil) | Its barium leaches at the TCLP limit or above. |
| [Waste pharmaceuticals](https://complyonsite.com/tools/rcra-waste-codes?waste=pharmaceuticals) | Its barium leaches at the TCLP limit or above. |
| Waste printing ink | Its barium leaches at the TCLP limit or above. |

## Which codes sit beside D005?
