PHA Certification Guide: TUV vs BPI vs DIN vs FDA — Complete Comparison
Everything you need to know about PHA biodegradable product certifications — what each one means, how to get certified, costs, timelines, and which certifications your products need.
Why Certifications Matter for PHA Products
In the biodegradable plastics market, certifications are the only credible proof that a product actually does what it claims. Without third-party certification, terms like "biodegradable," "compostable," and "eco-friendly" are meaningless marketing claims. Certifications protect buyers from greenwashing, ensure regulatory compliance, and provide the documentation needed for tenders, retail partnerships, and export.
For PHA products specifically, certifications verify three critical claims: (1) the material biodegrades under specified conditions, (2) the degradation products are non-toxic to ecosystems, and (3) for food-contact products, the material is safe for direct food contact. Each certification body tests different aspects using internationally recognized standards.

Frequently Asked Questions
Which certification is most important for PHA food packaging?
For PHA food packaging, you need both food contact safety certification AND compostability certification. Food contact: FDA 21 CFR (US market) or EU 10/2011 (EU market). Compostability: BPI (North America) or TUV OK Compost HOME (global). For marine claims, add TUV OK Compost MARINE. All PHApack food packaging products carry FDA + EU 10/2011 + BPI + OK Compost HOME.
How long does it take to get TUV OK Compost certification?
TUV OK Compost certification typically takes 8-14 weeks from sample submission to certificate issuance. The timeline depends on the specific certification type: OK Compost HOME and INDUSTRIAL take 8-12 weeks, while OK Compost MARINE takes 10-14 weeks due to additional marine biodegradation and ecotoxicity testing. PHApack products are pre-certified, so you receive certified products immediately without waiting.
Can I use the TUV or BPI logo on my packaging?
Yes, but only with a valid logo license agreement. TUV Austria and BPI both grant logo usage rights as part of the certification process. The logo license is tied to the specific certified product and manufacturer. If you purchase certified PHA products from PHApack, we can provide documentation supporting your marketing claims, but the logo license belongs to the certified entity (PHApack). For your own brand logo usage, you would need your own certification.
What is the difference between OK Compost HOME and OK Compost INDUSTRIAL?
OK Compost INDUSTRIAL requires biodegradation at 58°C (industrial composting facility conditions) within 6 months. OK Compost HOME requires biodegradation at ambient temperature (20-30°C, typical backyard compost) within 12 months. HOME certification is stricter and more valuable because it means consumers can compost the product at home without special facilities. All PHApack products carry OK Compost HOME certification.
Do I need separate certifications for each product or can one cover multiple products?
Certifications are product-specific. Each distinct product formulation requires its own certification. However, if multiple products use the same PHA resin formulation (e.g., different thicknesses of the same film), they may be covered under one certificate with product variants listed. PHApack maintains certifications for all 7 product lines, so you can source certified products immediately without individual certification costs.
