Recording hazardous waste and persistent organic pollutants (POPs)
Last checked 26 October 2026
Hazardous waste needs its hazard properties, the dangerous components and how much of each, and a consignment note code. Waste containing POPs needs the pollutant names and concentrations.
Is it hazardous?
Start with the waste code. Hazardous waste codes are marked with an asterisk in the list of waste codes, for example 17 05 03*. Some wastes have a pair of codes, one hazardous and one not, depending on what is in them; the details decide which applies.
What is asked for
- The hazardous property codes that apply (the HP codes, such as HP3 for flammable).
- The hazardous components in the waste, with the concentration of each where it is relevant.
- For waste containing persistent organic pollutants, the name of each pollutant and its concentration, usually in milligrams per kilogram.
- The consignment note code for the move. In England and Wales this looks like CJ32LE/A0001.
Where to find the details
Your customer, or the producer of the waste, should give you the waste description and any test results. If they have not, ask before you move it. You cannot make them up, and Defra can check them.
How Loadmark helps
Choose a hazardous waste code and Loadmark asks for the extra details on the same screen, one line per component, such as "Lead 120 mg/kg". It can hold several waste types on one load, each with its own details.
