Candle export certifications aren’t one thing — they’re three separate systems that cover different risks. IFRA governs what’s safe to put in the fragrance oil. ASTM (in the US) and EN 15493 (in the EU/UK) govern whether the burning candle itself is a fire hazard. CLP and GPSR govern what has to be printed on the label. A supplier who says “we’re certified” without telling you which of these three they mean hasn’t actually told you anything.
That distinction matters more than it sounds like it should, because it’s also the fastest way to catch a supplier who’s bluffing.
IFRA: What It Actually Covers (and Who’s Supposed to Issue It)
IFRA — the International Fragrance Association — sets maximum safe usage levels for fragrance ingredients, based on the product category they’re going into. A fragrance oil might be approved at 8% in a candle and 0.5% in a leave-on skincare product, because the exposure risk is completely different. The document that proves this is the IFRA Certificate of Conformity.
Here’s the part most buyers get backwards: an IFRA Certificate of Conformity is issued by the fragrance mixture manufacturer — not the raw material supplier, and not the candle factory. A candle manufacturer doesn’t “get IFRA certified.” What they can do is source fragrance oils that come with a valid certificate, and use them at or below the concentration that certificate allows for candles specifically.
So when a supplier tells you they’re “IFRA certified,” the useful follow-up question isn’t “can I see your certificate” — it’s “can you send me the IFRA Certificate of Conformity for the specific fragrance oil used in this product.” If they can’t produce one tied to the actual fragrance blend, the claim is marketing, not documentation.
US Market: ASTM Standards and CPSC Requirements
The two ASTM standards that matter most for candles entering the US are recognized by the Consumer Product Safety Commission as the voluntary baseline:
- ASTM F2417 — Fire Safety for Candles. Covers flame height, tip-over stability, and secondary ignition (whether the flame spreads somewhere it shouldn’t). Updated to its current version in 2023.
- ASTM F2058 — Candle Fire Safety Labeling. Specifies the actual warning text required on the label: things like “burn within sight,” “keep away from children,” and “trim wick to ¼ inch.”
CPSC recognizes several other voluntary ASTM standards covering specific candle accessories and formats, but F2417 and F2058 are the two that apply to essentially every candle shipment.
Two more US-specific requirements that catch buyers off guard:
Lead-cored wicks are banned. Since October 2003, candles sold in the US can’t use metal-cored wicks with more than 0.06% lead by weight in the core (16 CFR § 1500.17(a)(13)). Bulk shipments need a “Conforms to 16 CFR 1500.17(a)(13)” statement on the outer packaging. In practice this is a non-issue for most manufacturers now, since cotton and paper-core wicks dominate the market — but it’s worth confirming, especially on decorative or novelty formats that sometimes still use metal-core wicks for structural reasons.
Label coverage is specified, not just label content. Under the Fair Packaging and Labeling Act, a candle label on a rectangular container has to cover one full side; on a round container, it has to cover 40% of the surface. Buyers usually focus on what the label says and miss that where and how much of it is on the jar is also regulated.
EU and UK Market: CLP, EN 15493 and GPSR
Europe runs on three overlapping frameworks, and as of December 2024, that overlap got more complicated with a new one added.
CLP (Classification, Labelling and Packaging) governs fragrance allergen disclosure. If a fragrance allergen is present above a reportable threshold, it has to be named on the label. Below that threshold, many candles still need the statement “Contains [substance name]. May produce an allergic reaction.” (referred to as EUH208). Labels also need the name and address of the EU Responsible Person, and hazardous mixtures require a Poison Centre Notification with a Unique Formula Identifier printed on the label.
EN 15493 is the fire safety standard — the EU/UK equivalent of ASTM F2417. Key thresholds: flame height can’t exceed 75mm, there’s no secondary ignition, no excessive flaring or dripping, and the container has to stay structurally intact through the full burn.
GPSR (General Product Safety Regulation) is the new one. It took effect December 13, 2024, replacing the older General Product Safety Directive, and it applies to candles, diffusers and wax melts regardless of format. It requires a documented risk assessment covering fire behavior, inhalation risk, chemical hazards and packaging safety, plus a technical file that has to be kept for a minimum of 10 years after the product goes to market. This is newer and less consistently understood industry-wide than CLP or EN 15493 — if a supplier hasn’t mentioned it to you unprompted, ask.
Middle East and Australia: Less Standardized, Not Unregulated
Unlike the US and EU, there isn’t one dominant voluntary standard buyers can point to for Middle East or Australian markets — requirements tend to run through each country’s own customs and product safety authority rather than a single harmonized standard. That doesn’t mean anything goes; it means the compliance conversation for these markets usually needs to happen directly with your import partner or customs broker on the destination side, since requirements can vary by country and change without the kind of public documentation trail that ASTM or CLP standards have.
How to Vet a Supplier’s Compliance Claims
Most articles on this topic stop at explaining what the standards are. The more useful skill is knowing how to tell whether a supplier’s claim about them is real.
Ask for the document, tied to your product. Not “are you IFRA compliant” — ask for the IFRA Certificate of Conformity for the exact fragrance oil going into your exact product. A generic PDF that doesn’t name your fragrance blend isn’t proof of anything.
Cross-check the allergen declaration against the fragrance itself. If a supplier hands you a CLP label with no allergen statement at all, ask why — it’s either because the fragrance genuinely contains no reportable allergens (possible, but worth confirming) or because nobody checked.
Confirm wick material in writing. It’s a quick question and it closes off the lead-wick issue entirely.
Treat “we’re certified” as a red flag, not a green light, if it’s not attached to a specific document. None of IFRA, ASTM, CLP or GPSR issue a certificate to a factory that covers “everything, forever.” They cover specific formulations, specific tests, specific product runs. A supplier who talks in blanket terms either doesn’t understand the standards or is hoping you won’t ask which one they mean.
What This Means for Your AsterCandle Order
We manufacture with IFRA, ASTM and CLP expectations in mind for buyers shipping into the US, EU, UK and other regulated markets, and we can provide documentation relevant to your specific product and destination market on request — including the fragrance-level IFRA documentation described above, not just a generic compliance statement.
If you’re evaluating us alongside other manufacturers, ask the same questions this article walks through. It’s the fastest way to find out who actually has their compliance paperwork in order. See our full quality and compliance approach, or request a quote with your target market so we can flag anything specific to it early.
Frequently Asked Questions
Do I need different certifications for different countries?
Yes. IFRA fragrance standards are internationally recognized, but fire safety and labeling requirements are region-specific — ASTM F2417/F2058 for the US, EN 15493 and CLP for the EU/UK. A candle compliant for one market isn’t automatically compliant for another; check labeling and fire safety requirements separately for each destination.
Who is responsible for compliance — the manufacturer or the importer?
In practice, both. The manufacturer controls the formulation and construction that determines whether a candle passes fire safety and ingredient safety standards. The importer of record is typically who’s legally accountable for the product meeting destination-market requirements once it’s in-country, which is exactly why asking for documentation before you order matters more than assuming it exists.
What happens if a candle doesn’t meet these standards?
Consequences range from customs holds and forced relabeling to product recalls, depending on the market and the specific violation. Lead-cored wicks and missing allergen declarations are two of the more common triggers for enforcement action in the US and EU respectively.
