TL;DR: Writing a packaging specification without mapping your target market’s required standards is the most common reason sample rejections become full re-briefs — and re-briefs cost 3–6 weeks of project time.
For a related specification, compare Eco Certifications & Compliance — Supplier Qualification Guide before finalising the packaging brief.
TL;DR: The EN 13432 compostability standard and ASTM D6400 cover nearly the same claim, but they diverge on disintegration test conditions — EN requires 90% fragmentation at 12 weeks under ISO 20200, while ASTM uses a slightly different thermal profile — and mixing them in a single spec has failed audits we’ve seen on incoming brief reviews.
Why Standard References in Packaging Briefs Are Almost Always Wrong #
The brief comes in. It says “must comply with ISO recycled content standards and meet compostability requirements.” No market specified. No test method referenced. No threshold stated. This happens on roughly half the eco-focused briefs our specification team receives, and it creates a real problem: we can’t build a technically compliant sample without knowing which standard governs, and the standards for the same claim differ meaningfully between the EU, US, and China.
The confusion is understandable. Eco certification and compliance language has grown faster than buyers’ familiarity with the underlying test frameworks. A brand manager who hears “compostable packaging” at a trade show and types it into a brief has no reason to know that EN 13432 (EU), ASTM D6400 (US), and AS 4736 (Australia) each set different disintegration thresholds, different ecotoxicity criteria, and different labelling requirements. To the brand, it’s one concept. To a factory trying to source certified material and build a compliant structure, it’s three separate qualification tracks.
What makes this expensive is that the wrong standard reference doesn’t usually surface until the certification body reviews the finished sample — not during briefing, not during material sourcing, not during production. By that point, tooling may have been cut and printed sheets may already be in finishing. The re-work cost is one thing. The schedule impact is worse.
The Standards That Actually Govern Eco Packaging Claims — and Where They Diverge #
The table below maps the most commonly specified eco-related packaging standards across four major markets. A blank cell means no equivalent standard exists in that market for that claim — not that the claim is unregulated.
| Claim Type | EU Standard | US Standard | China Standard | Key Divergence |
|---|---|---|---|---|
| Industrial compostability | EN 13432 | ASTM D6400 | GB/T 19277-1 | Disintegration threshold: EN = 90% at 12 weeks; ASTM = 90% at 180 days max; GB/T follows ISO 14855 |
| Home compostability | NF T 51-800 (French) / no EU-wide | ASTM D6868 (partial) | Not standardised | EU home compost claims are nationally regulated; US D6868 covers coatings only |
| Recycled content (paper) | EN 15343 | No federal equivalent; state-level FTC Green Guides | GB/T 7974 (brightness proxy) | FTC requires substantiation but sets no test method; EN 15343 requires traceability chain |
| Recyclability (general) | ISO 18604 / EU PPWR Article 6 | APR Design Guide (voluntary) | GB/T 16288 recycling symbol | EU PPWR recyclability is mandatory by 2030; APR guidance is voluntary but retailer-required |
| Print ink migration (food contact) | EU 10/2011 + Ordinance 10 (Switzerland) | FDA 21 CFR 175–178 | GB 9685 | EU covers all layers; FDA regulates indirect contact; GB 9685 positive list differs from EU |
| Print quality (eco claim labels) | ISO 12647-2 (offset) | CGATS.21 / G7 | GB/T 17934 | G7 is a calibration methodology, not a standard — but US buyers treat it as equivalent to ISO 12647-2 |
The most commonly confused pair in our incoming briefs is EN 13432 and ASTM D6400. Both certify industrial compostability for packaging. Both require disintegration to less than 10% residual material passing a 2mm sieve. The key difference is temperature profiling during biodegradation testing: EN 13432 requires 58°C ± 2°C throughout the active phase per ISO 20200, while ASTM D6400 references ASTM D5338 which allows a ramp protocol. For a kraft-based folding carton with a PLA window patch, this temperature tolerance difference can push a material that passes one standard to borderline status on the other. We now flag this in our internal MAT-BRIEF-09 checklist before sourcing any compostable substrate.
The second most common confusion: ISO 14021 and ISO 14024. ISO 14021 covers self-declared environmental claims — the kind a brand makes on-pack without third-party verification, such as “made from 30% recycled content.” ISO 14024 covers Type I eco-labels, which require independent certification, like the EU Ecolabel or Nordic Swan. Using ISO 14021 language in a brief when the retailer requires ISO 14024-grade certification means the brand needs third-party verification they may not have arranged. We’ve held sampling pending clarification on this specific gap on three project reviews in the past 18 months.
Conditional Framework: Which Standard Applies to Your Project #
If your product ships primarily to the EU and carries any on-pack eco claim, your baseline stack is EN 13432 (if compostable), EN 15343 (if recycled content paper), and ISO 14021 or ISO 14024 depending on whether the claim is self-declared or certified. Under EU PPWR, packaging placed on the EU market must also meet recyclability requirements that phase in from 2030, with design-for-recyclability criteria currently being finalized under delegated acts. Brands entering EU retail in the next 2–3 years should already be specifying against these draft criteria.
If your product ships to the US, the FTC Green Guides (16 CFR Part 260) govern how eco claims can be worded, but the underlying test standards are typically voluntary. The exception is food contact: FDA 21 CFR Parts 175–178 are mandatory regardless of eco claims, and any recycled-content substrate used in direct food contact requires FDA evaluation. For compostability claims targeting US consumers, ASTM D6400 certification via BPI (Biodegradable Products Institute) is the de facto retailer requirement at Whole Foods, Target, and similar accounts.
If your product enters China, GB/T 16288 governs recycling identification marks and is mandatory under the Circular Economy Promotion Law for packaging materials above certain thresholds. GB/T 19277-1 applies to compostability claims, though market enforcement is lighter than in the EU. Japan sits outside this framework entirely: the Plastic Resource Circulation Act of 2022 requires biomass plastic content labelling under BiomassPla certification, which has no direct ISO or ASTM equivalent.
One non-obvious boundary condition: if you’re specifying printed eco labels on your outer carton — the recycling symbols, compostability logos, or FSC marks — those need to meet print registration tolerances that allow the logo to be legally reproduced. FSC trademark use requires meeting FSC-STD-50-001, which includes minimum size requirements (typically 15mm height for the FSC logo) and requires the print supplier to hold FSC Chain of Custody certification. Our offset lines carry FSC COC certification, and our standard registration tolerance of ±0.2mm on sheet-fed offset is well within the reproduction quality needed for compliant FSC logo printing.
Specification Notes for Brand Partners #
When you brief us on packaging that needs to carry an eco certification or comply with specific environmental standards, the single piece of information that most frequently delays quoting is the target market. “Compostable” means three different material sourcing exercises depending on whether you’re selling in Germany, California, or Australia.
What we need from you upfront: the destination market(s), the specific claims you intend to make on-pack, whether those claims are self-declared or require third-party certification, and the retailer or regulatory body whose requirements govern acceptance. If you have an existing certification (BPI, TÜV Austria OK Compost, DIN CERTCO), send us the certificate number — material sourcing becomes much faster.
The brief gap that causes the most sample iterations is not specifying which eco claim standard governs when two markets are in scope. If you’re selling to both the EU and the US with a compostable claim, we need to know whether to certify to EN 13432, ASTM D6400, or both — because the substrate qualification path differs, and dual certification adds 4–6 weeks to material sourcing.
Our standard timeline from confirmed brief to first eco-compliant sample is 20–25 working days for paper-based structures, assuming certified substrate is in stock. For novel materials or dual-market certification requirements, add 2–3 weeks for material qualification.
How do I know if my recycled content claim needs EN 15343 traceability documentation or if an FTC-style substantiation is enough?
It depends entirely on where the product is sold. EN 15343 is mandatory for recycled content claims on packaging sold in the EU under current and incoming PPWR rules — it requires a documented chain of custody back to the waste collection point. For the US, the FTC Green Guides require that claims be substantiated but don’t mandate a specific traceability standard. If you’re selling in both markets, default to EN 15343 since it satisfies both.
We’re targeting a “home compostable” claim. Is that covered by EN 13432?
No — EN 13432 covers industrial compostability only, meaning composting at 58°C in a managed facility. Home compostability, which must work at ambient temperatures (typically 20–30°C), is governed in France by NF T 51-800 and in Australia by AS 5810. There’s no single EU-wide home compost standard yet, which is a genuine gap. Our dataset on home-compostable substrate options is limited to materials that have passed NF T 51-800 or AS 5810; we haven’t tested materials against emerging German or Dutch national equivalents, and our material sourcing team’s position is to hold off until a harmonized EU approach is confirmed.
Can the same packaging structure be FSC certified and compostability certified simultaneously?
Yes, and this is increasingly common for premium food and personal care packaging. FSC Chain of Custody covers the paper fiber sourcing; EN 13432 or ASTM D6400 covers the end-of-life compostability claim. They govern different aspects and don’t conflict. The complication arises with coatings and adhesives: a compostable claim requires that all components, including inks, coatings, and adhesives, pass the same disintegration and ecotoxicity thresholds. Standard UV-cure coatings fail EN 13432 testing. We specify aqueous barrier coatings for compostable structures on our lines, which adds a cost delta worth confirming at quote stage.
