Every supplement packaging supplier lists certifications. Most buyers do not know which ones are independently verified, which are self-declared, and which ones are irrelevant to their specific product. This guide explains the difference.

Supplement packaging sits at the intersection of three regulatory territories: food contact compliance, environmental claims, and in some cases pharmaceutical-adjacent safety requirements. A packaging format that passes one territory cleanly may fail another. A supplier that holds one certification does not automatically hold the others.
The practical problem for supplement brands is that sustainability certification language has become marketing language. Terms like eco-friendly, plastic-free, recyclable, and biodegradable are used freely on packaging supplier websites without any independent verification backing them. A brand that uses a supplier's sustainability claims in its own product marketing is making a claim it cannot verify. Regulators in the US (FTC Green Guides) and EU (European Green Claims Directive) are increasingly enforcing against unverified environmental marketing claims. Greenwashing is no longer a reputational risk only. It is a legal one.
The certifications that matter are the ones that are independently audited, carry a verifiable certificate number, and cover the specific claim being made. Everything else is a marketing statement.

Supplement Tube Packaging
FSC certified · BPI compostable · BRCGS factory · MOQ 1,000 · Free samples
For supplement packaging specifically, four certifications cover the full range of claims a brand might legitimately need to make.
FSC — Forest Stewardship Council
Covers the paper fibre source. Chain-of-custody certification means every operator from forest to finished packaging has documented traceability and undergoes third-party audits. FSC 100% means all fibre from certified forests. FSC Mixed is a blend of certified and controlled sources.
What it lets you claim: responsibly sourced paper. Verify at: info.fsc.org
BPI — Biodegradable Products Institute
Independent US certification that tests products against ASTM D6400 (compostable plastics) and ASTM D6868 (compostable packaging coatings). BPI-certified products have been physically tested by a third-party laboratory, not just assessed against a checklist by the manufacturer.
What it lets you claim: independently verified compostable in commercial facilities. Verify at: bpiworld.org
BRCGS — British Retail Consortium Global Standards
Covers the manufacturing facility, not the material. BRCGS certification means the factory has been independently audited against global food safety standards covering hygiene, contamination controls, allergen management, and traceability. Required by most major UK and European retailers for food-contact packaging suppliers.
What it lets you claim: food-grade manufacturing. Verify at: brcgs.com
FDA 21 CFR 176 — Food Contact Compliance
Not a certification in the traditional sense — it is a regulatory compliance declaration. 21 CFR 176.170 covers paper and paperboard in contact with aqueous and fatty foods. 21 CFR 176.180 covers paper in dry food contact. Suppliers should be able to provide a written declaration of compliance with the specific CFR sections relevant to your product's contact classification.
What it lets you claim: FDA food contact compliant inner lining. Ask for the declaration document, not just a verbal assurance.
FSC tells you about the paper source. It says nothing about what the inner liner is made from, whether the adhesive is synthetic or natural, or whether the manufacturing environment meets food safety standards. A tube can be FSC-certified and still contain a plastic inner liner, petroleum-based adhesives, and be manufactured in a facility with no food safety controls.
BPI certifies compostability of the finished product or specific components. It does not cover barrier performance, food contact safety, or manufacturing standards.
BRCGS covers the factory. It says nothing about the materials going in.
FDA 21 CFR compliance covers food contact safety of the inner surface. It says nothing about the outer material, the adhesive system, or the end-of-life profile.
The full picture requires all four
A supplement packaging supplier that genuinely covers all the claims relevant to your brand will hold FSC (paper sourcing), BPI (compostability), BRCGS (manufacturing), and be able to provide FDA 21 CFR compliance documentation for food contact. Each covers a different dimension. None of them overlap. Holding one does not imply holding the others.
Some certifications appear on supplier websites frequently but provide limited actionable value for supplement brands evaluating packaging.
| Certification | What It Covers | Relevance for Supplement Packaging |
|---|---|---|
| ISO 9001 | Quality management systems | General quality indicator, does not cover food safety or sustainability claims specifically |
| ISO 14001 | Environmental management systems | Covers how a factory manages its environmental impact, not the product's sustainability profile |
| Sedex/SMETA | Ethical trade and supply chain audit | Important for ethical sourcing claims but does not cover material safety or sustainability performance |
| Self-declared recyclable | No third-party verification | Not independently verified. FTC Green Guides require recyclable claims to be substantiated with evidence that recycling facilities are available to a substantial majority of consumers |
Step 1 — Ask for certificate numbers, not just badge images
Every legitimate FSC, BPI, and BRCGS certificate carries a unique identifier. Search that number in the respective certification body's public database. If the supplier cannot provide a number, the certification may be expired, pending, or fabricated.
Step 2 — Check the scope of the certification
BRCGS certificates list the specific product categories and processes covered. A supplier certified for packaging manufacturing is not automatically certified for food-contact packaging manufacturing. Check the scope document, not just the certificate.
Step 3 — Request the FDA compliance declaration in writing
A reputable food-contact packaging supplier will provide a written declaration specifying which CFR sections the inner liner and adhesive system comply with. This is a standard document request. Hesitation to provide it is a meaningful signal.
Step 4 — Test a sample with your actual product before production
Certifications cover the packaging material in standard conditions. Your product may have specific pH, moisture, or oil content that interacts with the inner liner differently. Fill a production sample and store it under your normal warehouse conditions for 4 to 6 weeks before approving a production run.
Earthycores Certification Summary
FSC chain-of-custody certified — certificate number available on request
BPI independently verified compostable — tested to ASTM D6400 and D6868
BRCGS food-grade manufacturing — factory independently audited
FDA 21 CFR 176.170 and 176.180 compliance documentation available
Soy-based ink printing across all paper substrates
Own factory operating since 2012 — no third-party manufacturing
FSC covers paper sourcing. BPI covers compostability. BRCGS covers manufacturing safety. FDA 21 CFR covers food contact compliance. Each is independently verifiable. None of them substitute for the others. A supplement brand making sustainability claims on its packaging needs to be able to verify each claim against a specific certification, not a supplier's marketing language.
Ask every packaging supplier for certificate numbers. Search those numbers in public databases. Request FDA compliance documentation in writing. That process takes less than an hour and eliminates most of the risk of building a sustainability claim on a foundation that does not hold up.
