EN13432 is the European Union’s definitive compostability standard for packaging materials, and a cornerstone of EU-wide plastic waste regulation. It defines whether a product can legally be labeled and marketed as “compostable” under European law. By contrast, ASTM D6400 is a U.S.-based standard developed by ASTM International, primarily targeting North American markets. The two share similarities in performance thresholds (biodegradability, disintegration, eco-toxicity), but differ in: Feature EN13432 ASTM D6400 Composting time limit 6 months 6 months CO₂ conversion requirement ≥90% ≥60% Heavy metals limit Strict (EU thresholds) Moderate Disintegration (2mm screen) Required Required Plant growth toxicity test Mandatory Mandatory Acceptance for labeling in EU Yes No Conclusion: For any product claiming to be compostable and seeking to enter the European market—especially under Directive (EU) 2019/904—EN13432 is legally required, not optional.

Materials like PLA, bagasse, and uncoated paper fiber can meet both EN13432 and ASTM D6400 standards when processed properly. Mixed materials (e.g., plastic blends, oxo-degradables) typically do not qualify.
