The Unified Soil Classification System ( USCS ) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil . The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt ):

For example, SP-SM could refer to "poorly graded SAND with silt" or "poorly graded SAND with silt and gravel."

30-412: The soil has 5–12% by weight of fines passing a #200 sieve (5% < P #200 < 12%), both grain size distribution and plasticity have a significant effect on the engineering properties of the soil, and dual notation may be used for the group symbol. For example, GW-GM corresponds to "well-graded gravel with silt ." If the soil has more than 15% by weight retained on a #4 sieve (R #4 > 15%), there
