The ASTM International Resin Identification Coding System, often abbreviated RIC, is a set of symbols appearing on plastic products that identify the plastic resin out of which the product is made.[1] It was developed in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association) in the United States, but since 2008 it has been administered by ASTM International, an international standards organization.[1]
Due to resemblance to the recycling symbol, RIC symbols are often mistaken for the former.[2] Subsequent revisions to the RIC have replaced the arrows with a solid triangle, but the old symbols are still in common use.
