# D002 RCRA waste code Strong acids & caustics, at pH 2 or lower or 12.5 or higher.

> D002 RCRA waste code. Corrosive waste is characteristic hazardous waste. Aqueous waste at pH 2 or lower or 12.5 or higher, or liquid that eats through steel.

## Is D002 hazardous waste?

**Yes.** D002 is hazardous waste when a representative sample meets either federal corrosivity test. The pH test is for aqueous waste. The steel-corrosion test is for liquid waste and stands alone.

D002 is a nonacute characteristic. On a required [hazardous waste manifest](https://complyonsite.com/tools/hazardous-waste-manifest), put D002 in Item 13. See [VSQG exemptions and empty-container rules](https://complyonsite.com/tools/rcra-waste-codes?list=routes).

## What does D002 cover?

D002 covers aqueous waste with a pH of 2 or lower, or 12.5 or higher, measured by Method 9040C. It also covers a liquid that corrodes SAE 1020 steel faster than 6.35 mm (0.250 inch) per year at 55 °C (130 °F), measured by Method 1110A. Either result is enough.

- **Hazard**: C, corrosive
- **Rule**: [40 CFR 261.22](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-261/section-261.22)

## Is corrosive waste D002 or D001?

| Code | When it fits |
| --- | --- |
| D002 | An aqueous sample meets either pH limit, or a liquid exceeds the steel-corrosion rate. |
| [D001](https://complyonsite.com/tools/rcra-waste-codes?code=d001) | The waste isn't D002 but meets an ignitability criterion on its own. |
| No D002 code | Neither corrosivity test is met. Check every other characteristic and listing. |

Only aqueous waste takes the pH test, but any liquid can take the steel-corrosion test. The testing or knowledge behind the call must support the test you use.

## Which wastes take D002?

| Waste | When it’s D002 |
| --- | --- |
| [Acid waste](https://complyonsite.com/tools/rcra-waste-codes?waste=acid-waste) | An aqueous sample has pH 2 or lower, or the liquid corrodes steel at the federal test rate. |
| [Caustic or alkaline waste](https://complyonsite.com/tools/rcra-waste-codes?waste=caustic-waste) | An aqueous sample has pH 12.5 or higher, or the liquid corrodes steel at the federal test rate. |
| Paint stripping waste | A representative sample meets the corrosivity definition, such as a caustic stripper. |
| Radiator repair waste | Zinc-chloride coolant or cleaning liquid meets the corrosivity definition. |
| Shop drain and sump sludge | The sludge's aqueous pH or liquid steel corrosion meets the D002 test. |
| Tank bottoms and product heels | The residue is corrosive. |
| Tank and railcar washwater | The washwater's aqueous pH or liquid steel corrosion meets the D002 test. |
| [Spent rust-removal acid](https://complyonsite.com/tools/rcra-waste-codes?waste=rust-removal-acid) | The waste meets the corrosivity definition. |
