HP10: Toxic for reproduction
Waste which has adverse effects on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring.
What this usually means in practice
HP10 covers reproductive toxicity, including harm to fertility and development of the unborn child. It is often relevant where the waste contains substances with well-established reproductive hazard classifications.
Definition
Exact definition wording taken from WM3 Appendix C / Annex III for this hazardous property.
waste which has adverse effects on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring
What to check when assessing this property
Use the official definition, composition data and waste-process knowledge together. These points are meant to help frame the assessment, not replace WM3.
- Review H360 and H361 substances individually — HP10 is assessed per substance, not as a summed concentration.
- Check whether the waste stream concentrates specific additives, solvents or metal compounds known for reproductive toxicity.
- Use up-to-date composition evidence, especially for mixed or legacy wastes where formulation may have changed.
Supporting points
Additional points shown where the official definition or WM3 guidance breaks the hazard into categories or clarifications.
- H360 Repr. 1A or 1B triggers HP10 at 0.3% or more; H361 Repr. 2 triggers HP10 at 3.0% or more.
How to use this page
Hazardous properties explain why a waste may be hazardous. They sit alongside EWC classification and they do not replace formal WM3 assessment or site acceptance checks.
1. Start with the waste
Identify the likely EWC entry, the process that produced the waste and whether it is part of a mirror-entry assessment.
2. Check the hazard evidence
Use composition data, SDSs, testing, pH, flash point and process knowledge as relevant to the property in question.
3. Confirm the final outcome
Confirm the conclusion against WM3 and any permit-specific or site-specific acceptance requirements before relying on it.
Wording is based on Annex III of the consolidated Waste Framework Directive opens in a new tab and should be used alongside Waste classification technical guidance (WM3, 3rd edition, 2021) — GOV.UK opens in a new tab.
