Green Product Evaluation. Bio-based Materials and Products

1 Scope

GB/T 46658-2025 is the Chinese national standard covering assessing a biobased product - the biobased carbon content measured rather than declared, the feedstock and whether it competes with food, the energy and emissions of production, the end of life, and the indicators that decide the green label. First edition, in force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026.

This document specifies the evaluation requirements for green products based on bio-based materials and products, and describes the evaluation methods. This document applies to the green product evaluation of bio-based materials and products, including bio-based polymers, bio-based plastics, and bio-based synthetic chemicals. Evaluation of fiber, bio-based coatings, etc.
