ASTM D6400 compostable certification

The US route to a compostable claim, covering plastics under D6400 and coatings, laminates and fibre-based packaging under D6868, as independent third-party certification with legal weight.

Where it's used

Biodegradability standardization and testing (ISO 17088, EN 13432)
The certification machinery that decides whether a material may be called compostable — EN 13432 and ASTM D6400 conformity, the Seedling scheme whose 2026 revision tightens biodegradability evidence for minor constituents, home-compost certification at 180 days, and the laboratory battery of biodegradation, disintegration, ecotoxicity and heavy-metal testing beneath the labels.
