02 04 99 Wastes not otherwise specified

EWC / List of Waste code · Last checked 21 October 2026 · Applies across the UK (England, Wales, Scotland and Northern Ireland)

Not hazardous Absolute non-hazardous entry

Official description: “wastes not otherwise specified”

Where it sits: chapter 02 (wastes from agriculture, horticulture, aquaculture, forestry, hunting and fishing, food preparation and processing), section 02 04 (wastes from sugar processing).

What the hazard status means

Waste that matches this description is not hazardous waste. Check that nothing hazardous has been mixed in: a load that contains hazardous waste needs a different code.

Codes ending in 99 (“not otherwise specified”) are a last resort. Use a more specific code if one fits the waste.

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.

02 04 01 Soil from cleaning and washing beet Not hazardous

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.
