The ASTM International Resin Identification Coding System (RIC) is a set of symbols developed in 1988 appearing on plastics that identify the plastic resin out of which the product is made.

The RIC system by ATM International was designed to make it easier for workers in materials recovery and recycling facilities to sort and separate items according to their resin type.

Plastics must be recycled separately, with like materials, in order to preserve the material’s value and enable its reuse in other products after being recycled.
