A certification is an independently verified standard with documented criteria — EPA Safer Choice, ECOCERT, ISO 9235, Clean at Sephora, and IFRA 51 are real certifications maintained by independent bodies. A 'clean' or 'non-toxic' marketing claim has no agreed-upon definition and isn't independently verified. Stock Fragrance ties every claim we make to a specific certification with verifiable criteria — never to vague marketing language.

A Stock Fragrance oil can carry up to 25+ verified compliance attributes depending on its formulation — including EPA Safer Choice, ISO 9235 (plant-based), ECOCERT, IFRA 51, Clean at Sephora, Target Clean, Credo Clean, Made in USA, Hypoallergenic, Biodegradable (>90%), and ingredient-exclusion claims for phthalates, parabens, BHT, lilial, PEG, PFAS, CMR substances, PBT substances, non-GMO, gluten-free, and cruelty-free / vegan formulations. The full list per oil is on every product page Documentation tab.

Independently verified. EPA Safer Choice is a US federal certification administered by the Environmental Protection Agency. ECOCERT is an independent certifier with global standing. ISO 9235 is an international standard. Clean at Sephora and Target Clean are retailer-administered programs with public criteria. IFRA 51 is the International Fragrance Association's safety standard. Every claim on a Stock Fragrance oil is traceable to the issuing body and the audit documentation.

Certifications are typically issued at the finished-product level, so we don't certify oils. What we do is pre-screen each formula against the certification's published criteria to ensure it will pass should you choose to certify your product. "Compliant" on this page means exactly that: the oil has been verified against the standard's criteria, so the fragrance won't be the reason a product-level certification fails.

That's really up to what matters most to your brand. Every certification measures something different, and the same oil can pass one and fail another — so there's no universal ranking. Choose the standards that matter most for your positioning, your retail channel, and your market, then select oils verified against those.

No — if the oil passes against a certification's criteria now, it will pass in your product. The one exception is when the certification itself changes its criteria, which happens often. Certification standards are a constantly moving target — which is why compliance is verified against the current edition of each standard.

It depends on the change. Some updates are minor; others would make it impossible to keep an oil's olfactive character using different ingredients. We formulate to the olfactive character first — so when a standard changes, what still passes, passes, and what doesn't, doesn't: the oil's compliance list is updated rather than its scent. If your finished product is already certified, check with the issuing body on how it treats existing certifications when criteria change.

No — our checks are free. Pre-screening is built into how we formulate, and compliance documentation is posted on each product page at no charge. Certifying your finished product is a different matter: issuing bodies charge for product-level certification, sometimes a lot, so factor that into your plans.

Check with the issuer. Some standards on this page are international (ISO 9235, IFRA), while others are tied to a specific market or regulator (EPA Safer Choice, California Prop 65). Whether a claim carries weight in another market is the issuing body's call — confirm with them before relying on it for export.

Most certifications operate on annual or biennial renewal cycles, and criteria change often — IFRA's amendments are roughly biennial, and retailer lists update on their own schedules. Regulatory requirements are constantly changing, so always check the current documentation on the product page (or ask us) before relying on a claim.

Each product page has a Documentation tab with that oil's available documents — typically the SDS and IFRA 51 Regulatory Data Sheet, plus additional statements depending on the oil — downloadable individually. Available documents vary by fragrance. For consolidated documentation packages, custom compliance statements, or specific cert letters, use the Document Request form.

Both. Stock Fragrance oils are produced exclusively at a family-owned facility in business since 1871 — now in its 5th generation. The manufacturer holds facility-level certifications (ISO 9001, GMP, etc.) and our formulas are independently verified against the cert criteria for each oil. The combination means both the substance and the process are documented.
