What is ISO 16620?

ISO 16620:2019 is a standard designed to measure and declare the bio-based content of plastic products, especially the bio-based carbon content. It applies analytical methods like radiocarbon analysis (14C) to determine the percentage of carbon derived from renewable resources. This certification provides businesses with a credible way to support green labeling, life-cycle assessments (LCAs), and regulatory compliance.

The ISO 16620 series includes multiple parts, but the most widely adopted for certification and product declarations is:

  1. ISO 16620-2:2019 – Focused on the quantification of bio-based carbon content.


Why is ISO 16620 important?

With increasing global emphasis on sustainable materials, carbon footprint reduction, and eco-labeling, ISO 16620 is becoming a key differentiator for companies looking to market their products as bio-based or environmentally friendly. Whether you're exporting to regions with strict sustainability regulations (like the EU) or catering to green-conscious consumers, ISO 16620 certification gives you a competitive advantage and ensures transparency in your product claims.

Additionally, governments, procurement bodies, and large brands are now prioritizing bio-based plastic products in their sourcing policies — making this standard crucial for business growth and market entry.
