Where it sits: chapter 07 (wastes from organic chemical processes), section 07 05 (wastes from the MFSU of pharmaceuticals).

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.
