Compostable Bags Compliance for Global Markets
In global B2B packaging markets, “compostable” is a regulated claim, not a marketing term.
Different countries apply different compostability standards to bags and packaging. Without the correct certification, products may be rejected by importers, retailers, councils, or composting facilities.
This page provides a clear compliance overview and links to standard-specific guidance for compostable bags used in the EU, United States, Australia, and other international markets.
What Does Compostable Bags Compliance Mean?
Compostable bags compliance means that a product:
- Breaks down under defined composting conditions
- Leaves no toxic residue or microplastics
- Meets time, temperature, and material safety limits
- Is verified by independent, accredited certification bodies
Compliance is standard-based, not self-declared. Claims such as “biodegradable” or “eco-friendly” alone do not equal compliance.
