Most sellers think of a candle as a finished product, like a mug or a lamp. EU chemicals regulators see it differently. The European Chemicals Agency (ECHA) states in its 2024 fact sheet for candle makers that candle products, wax melts included, "are chemical mixtures under the EU regulations REACH and CLP". That one sentence decides a lot. A mixture can need a hazard label under the CLP Regulation (Regulation (EC) No 1272/2008), and whether yours does depends mainly on the fragrance you put in it.
For sellers outside the EU there is a second, newer point. Since 1 July 2026, a mixture may only be placed on the EU market if a supplier established in the EU takes responsibility for it and is named on the label. For a scented candle that needs a CLP label, a parcel shipped from China, the UK or the US straight to a consumer in Germany, with the factory's details on the box, no longer meets that rule.
This article explains when a candle or reed diffuser needs a CLP label, what the label must show, which extra packaging rules apply to diffusers, and how CLP relates to the fire safety rules under the GPSR.

Why a candle falls under the CLP Regulation
The CLP Regulation applies to substances and mixtures, not to articles. Read on its own, the regulation never mentions candles, so the classification comes from guidance. ECHA's candle fact sheet treats candles and wax melts as mixtures, and national CLP authorities such as the Irish Health and Safety Authority take the same line for candles and diffusers. The logic is easy to follow: the wax and the fragrance are there to be burned or evaporated, so they are the product, not just its shape. ECHA's general guidance on articles uses the same reasoning for a wax crayon.
The wick is a separate matter. For notifications under EU waste law, ECHA describes a candle as "a combination of a mixture and an article", with a wick containing boric acid as its example.
In practice this is the position authorities enforce, so treat it as settled. The question is not whether CLP can apply to your candle, but whether your particular candle meets one of the conditions that trigger a label.
When a scented candle needs a CLP label
A candle needs a CLP label in two situations, according to ECHA's fact sheet: when the candle as a whole is classified as hazardous, or when it must carry the EUH208 statement. Both usually come from the fragrance.
Many fragrance ingredients are skin sensitisers, substances that can cause an allergic skin reaction. The safety data sheet of the fragrance oil shows their category in section 2 or 3, for example "Skin Sens. 1B, H317". If enough of them end up in the candle, the whole candle is classified as a skin sensitiser and gets the exclamation mark pictogram, the signal word "Warning" and the hazard statement H317, "May cause an allergic skin reaction". Below that level, a smaller amount still triggers a warning line without a pictogram.
| Sensitiser in the candle (per substance) | Result |
|---|---|
| Category 1 or 1B at 1% or more, or category 1A at 0.1% or more | Classified as skin sensitiser: pictogram, "Warning", H317 |
| Category 1 or 1B at 0.1% or more, or category 1A at 0.01% or more | No classification, but the label must say EUH208: "Contains (name of sensitising substance). May produce an allergic reaction." |
| Below those limits | No CLP label for skin sensitisation |
The limits come from Annex I, Tables 3.4.5 and 3.4.6, and Annex II, section 2.8 of the CLP Regulation. Where a substance has its own specific concentration limit, that limit applies instead, and the EUH208 threshold is a tenth of it.
ECHA gives an example that matches many candles on the market: a candle with 10% of a perfume classified as sensitising is likely to contain more than 1% of a sensitiser, and is then classified itself. Classification for harm to aquatic life, such as H412, is less common in candles but possible, depending on the fragrance.
You cannot work this out from the candle alone. You need the safety data sheet of the fragrance oil, the percentage you use, and a calculation per substance. This is the step to get right before you print a single label.
What the CLP label must show
Article 17 of the CLP Regulation lists what goes on the label of a classified mixture:
- name, address and telephone number of the supplier
- nominal quantity, for packages sold to the general public, unless shown elsewhere on the package
- product identifier: the trade name plus the sensitising substances that cause the classification (Article 18(3))
- hazard pictogram, signal word and hazard statements
- precautionary statements, such as keeping the product out of reach of children
- supplemental information, which is where EUH208 and a UFI code go (Article 25)
The label must be in the official language or languages of each EU country where the product is sold (Article 17(2)), so a candle sold in Germany needs German on the label and one sold in France needs French. Claims such as "non-toxic" or "natural and safe" are not allowed on the label or packaging (Article 25(4)).
Where the label goes matters as much as what it says. ECHA states that a CLP label cannot be applied directly to the candle wax, and that an open glass container, the aluminium cup of a tea light or an openwork paper box do not count as adequate packaging. The label belongs on the packaging that holds the candle. For a candle in a jar with a lid or in a closed box, that is usually straightforward. For loose pillar candles or tea lights sold without closed packaging, it means changing the packaging.

Reed diffusers: child-resistant caps and tactile warnings
The liquid in a reed diffuser is a mixture too, and because it is a liquid, extra packaging rules apply under Article 35 and Annex II, Part 3 of the CLP Regulation.
Many diffuser liquids are based on hydrocarbon solvents. A mixture that contains at least 10% of ingredients classified as aspiration hazard category 1, many of them hydrocarbon solvents, and has a kinematic viscosity of 20.5 mm²/s or less at 40 °C is classified as an aspiration hazard (Annex I, section 3.10). When a diffuser liquid is classified as an aspiration hazard (category 1, H304, "May be fatal if swallowed and enters airways"), the bottle sold to consumers needs a child-resistant fastening (Annex II, section 3.1.1.2) and a tactile warning, the raised triangle that people with impaired sight can feel (section 3.2.1.1). A diffuser classified as a flammable liquid in category 1 or 2 also needs the tactile warning. Skin sensitisation alone triggers neither.
The relief for small packages does not help much here. For packages of 125 ml or less, hazard and precautionary statements may be left out for some hazard classes (Annex I, section 1.5.2.1), but skin sensitisation and aspiration hazard are not among them.
Enforcement in this product group is real. In an inspection campaign on scented products such as diffuser oils, room sprays and air fresheners, the Irish Health and Safety Authority found that 60% did not meet the CLP hazard labelling rules. Among products imported from outside the EU, the figure was 78%. Candles were not part of that campaign.
The EU supplier on the label since July 2026
The CLP Regulation was written on the assumption that every company in the supply chain is in the EU. Its definitions of manufacturer, importer, downstream user and distributor all require establishment in the EU, and the "supplier" named on the label is one of them. A factory in Ningbo or a brand in Manchester cannot be that supplier.
For years this left a gap, which the EU closed with Regulation (EU) 2024/2865. Its first recital says it plainly: companies outside the EU sell chemicals online directly to consumers, authorities cannot enforce the rules against them, and the consumer should not become the importer by default. Since 1 July 2026, the new Article 4(11) applies: a substance or mixture may not be placed on the market "unless a supplier established in the Union, which shall be identified on the label", fulfils the CLP requirements.
For a non-EU seller of a candle or diffuser liquid, that means an EU company must act as importer under CLP: it classifies the product and, where a label is needed (classified or only with EUH208), approves the label and appears on it as supplier. If the mixture is classified for health or physical hazards, the importer or downstream user must also notify it to the poison centres (Article 45 and Annex VIII) and print the resulting UFI code on the label. That notification is needed in every member state where the product is sold, and a candle maker cannot reuse the UFI of its fragrance supplier, according to ECHA.
Do not confuse this with the GPSR. Every consumer product sold in the EU needs an economic operator in the EU under Article 16 of the GPSR, often called the EU Responsible Person, whose name and contact details must be on the product, its packaging, the parcel or an accompanying document. That role exists for product safety in general. The CLP supplier is a separate role with its own duties, and being named as GPSR responsible person does not make a company your CLP supplier. A candle with a CLP label needs both. Our EU Authorised Representative service under the GPSR covers the GPSR role only, not the CLP supplier role.
Fire safety: the GPSR and the candle standards
CLP covers the chemical hazards of a candle. The other risks, above all fire, fall under the General Product Safety Regulation (Regulation (EU) 2023/988). Under its Article 2(1), the GPSR applies to the risks that more specific EU law does not cover.
Three European standards deal with those other risks: EN 15493 (fire safety), EN 15494 (product safety labels for indoor candles) and EN 15426 (sooting behaviour). They are not referenced in the Official Journal under the GPSR; the current list in Implementing Decision (EU) 2026/901 contains no candle standard. Meeting them therefore does not give you an automatic presumption of safety. They are still the recognised benchmark a market surveillance authority is likely to look at when it assesses whether your candle is safe under Article 8 of the GPSR, and the obvious tests to support your GPSR risk assessment.
In practice a scented candle sold in the EU should therefore carry two kinds of information: the CLP elements when the fragrance triggers them, and the fire safety warnings and symbols that EN 15494 describes. Our overview of EU product testing shows how candles fit in next to other product groups.
What changes in 2028
Regulation (EU) 2024/2865 also sets new formatting rules for CLP labels: a minimum font size, black text on a white background, a minimum line spacing and one easily legible font. After a further delay by Regulation (EU) 2025/2439, these apply from 1 January 2028. For packages up to 0.5 litre, which covers most candles and diffusers, the minimum x-height (the height of a lowercase letter x) is 1.2 mm.
Your online listing already has to show hazard information today. An offer for a mixture that is classified or needs EUH208, where the buyer cannot see the label before buying, must mention the type of hazard shown on the label (Article 48(2)). From 1 January 2028, the new Article 48a goes further: a distance sales offer must clearly and visibly show all CLP label elements. For a seller on Amazon, Etsy or a webshop, the hazard information therefore belongs in the listing itself, not only on the box.
Two simpler options have been available since 1 July 2026: fold-out labels as a regular option, and a digital label as an addition to the physical one. The European Parliament and the Council reached a political agreement in June 2026 to simplify these formatting and online sales rules again. Formal adoption is still pending (October 2026), so check the rules in force before you print labels for 2028.
Checklist for CLP labelling of candles and diffusers
- Get the safety data sheet of every fragrance oil and note the percentage you use per product.
- Calculate per sensitising substance whether the candle or diffuser is classified (H317) or needs EUH208.
- For diffusers, check the classification of the liquid: aspiration hazard and flammability decide on child-resistant caps and tactile warnings.
- Put the label on closed packaging, not on the wax, in the language of every country you sell to, without claims like "non-toxic".
- Arrange an EU-established supplier for every candle or diffuser liquid that needs a CLP label and name it on the label; arrange the poison centre notification and UFI where needed.
- Name your EU Responsible Person under the GPSR separately on product, packaging, parcel or accompanying document.
- For candles, test against EN 15493 and EN 15426, label according to EN 15494, and keep the reports in your technical documentation.
- Show the type of hazard in your online listing now, and all label elements from 1 January 2028.
