Official description: “wastes containing hazardous substances from physical and chemical processing of non-metalliferous minerals”

Where it sits: chapter 01 (wastes resulting from exploration, mining, quarrying, and physical and chemical treatment of minerals), section 01 04 (wastes from physical and chemical processing of non-metalliferous minerals).

What the hazard status means

This is one half of a “mirror” pair. Use this hazardous code if the waste contains hazardous substances above the thresholds, or has hazardous properties. You must assess the waste first, usually by knowing exactly what it is made of or by sampling and testing it.

Using this code

Write the code on the paperwork when waste is passed on: a waste transfer note for non-hazardous waste, or a consignment note for hazardous waste (called special waste in Scotland).
Choose the code from where the waste came from first (the chapter), then what it is. If a load is mixed, you may need more than one code.
The waste must go to a site whose permit allows that code. A registered carrier can tell you which codes they accept: check a waste carrier.
Businesses have a duty of care to describe their waste correctly.

This page explains the code in plain English. It is not a classification of your waste. The official List of Waste and the classification guidance decide which code applies, and you are responsible for the code you use.
