As the name suggests, is the top layer of soil, which is usually fertile and high in organic matter and nutrients. It can be used in a variety of commercial and domestic projects such as landscaping or for laying lawns.

This standard covers natural and manufactured topsoil that is moved or traded, not material that remains in situ.
Many areas have low-quality soils, but more specifically development sites where the natural top layer of soil has been stripped away during construction. These sites will be covered in a layer of fertile material to allow for the growth of turf, plants, or vegetation to create a new landscape.
It can also be used in gardens where there might be no access to soil.

Multipurpose – This is regularly used and is suitable for most gardening/landscaping projects.
Specific Purpose – This is a very specific grading where the project may require different characteristics such as acidic soil, calcareous soil, or low fertility.
BS3882:2015 sets out the requirements for classification and composition. it specifies the characteristics such as texture, acidity, and contaminants. It includes information on sampling & analysis and gives guidance on handling and site preparation so that the soil is not degraded during excavation, delivery, or placement.

Suppliers are required to declare the results of the analysis which includes:
