CLP Labels for Candles: What Every UK Candle Maker Needs

Every scented candle sold in the UK needs a CLP label. The fragrance oil in your candle makes it a chemical mixture, and UK law requires you to classify it and communicate the hazards through a compliant label.

But "scented candle" covers a wide range of products — container candles, pillar candles, tea lights, votives, and more. Each format has the same CLP obligations, but the practical details of how you apply the label differ. This guide focuses on what candle makers specifically need to know.

For the full CLP regulatory background and all six required label elements, see our complete CLP labels guide. For a step-by-step classification walkthrough, see our CLP labelling guide for candle and wax melt makers.

This guide covers GB CLP requirements. This is not legal advice.

Which Candles Need CLP Labels?

Scented candles — yes. Any candle containing fragrance oil or essential oil is a chemical mixture that must be classified under GB CLP. If it classifies as hazardous (and scented candles almost always do), it needs a CLP label.

Unscented candles — check your ingredients. A plain soy or paraffin wax candle with no fragrance oil, dye, or other chemical additives may not classify as hazardous. But if you add dyes, UV stabilisers, or any other chemical ingredient, you need to check whether the product classifies as hazardous based on those additions. When in doubt, review the Safety Data Sheets for every ingredient.

Decorative candles sold as ornaments — if the candle is marketed purely as decoration and not for burning, it may fall outside CLP scope, but this depends on the specific circumstances and how the product is presented. Seek specific advice if you sell decorative-only candles. The moment you suggest it can be lit, CLP requirements apply.

Typical CLP Classifications for Scented Candles

The exact classification of your candle depends on your specific formulation — the fragrance oil, its concentration, and the individual hazardous components within it. You cannot use generic classifications; each formulation must be assessed individually using your suppliers' Safety Data Sheets.

That said, here are the hazard categories that commonly apply to scented candles at typical fragrance loads (6–10% by weight):

Almost always present:

• Flammable (H226 — Flammable liquid and vapour): Some fragrance oils have flash points that can trigger flammable classification in the finished product, depending on the concentration and the product's overall physical properties. Check whether your finished candle — not just the raw fragrance oil — meets the flammable liquid criteria under CLP.
• Skin sensitisation (H317 — May cause an allergic skin reaction): Fragrance components like linalool, limonene, citronellol, and eugenol are classified as skin sensitisers. At 8% fragrance load, these components often exceed the 1% threshold in the finished candle.

Common but formulation-dependent:

• Eye irritation (H319 — Causes serious eye irritation): Some fragrance blends contain components that are eye irritants at concentrations above the classification threshold.
• Aquatic toxicity (H411 or H412 — Harmful to aquatic life): Certain fragrance ingredients are toxic to aquatic organisms. Whether this applies depends on the specific components and their concentrations.

Less common for candles:

• Aspiration hazard (H304): Rare at candle fragrance loads but possible with very high concentrations of certain hydrocarbon-based fragrance components.
• Corrosion/serious eye damage (H318): Unusual for candles but can occur with specific ingredients at high concentrations.

The corresponding pictograms for a typical scented candle are GHS07 (exclamation mark — for skin sensitisation and/or eye irritation) and potentially GHS02 (flame — if the finished product classifies as flammable based on its own properties). Reed diffusers and room sprays with the same fragrance oil but higher concentrations often carry additional pictograms.

Candle Safety Labels vs CLP Labels

A CLP label and a candle safety label are two different things — they serve different purposes and come from different requirements. Most candle sellers need both.

CLP label: Legally required under GB CLP for any hazardous chemical mixture. Contains hazard pictograms, signal word, H/P statements, supplier details, product identifier, and nominal quantity. This is a regulatory obligation enforced by trading standards.

Candle safety label: A voluntary fire safety label based on general product safety best practice, often expected by retailers and insurers. Contains instructions like "Never leave a burning candle unattended" and "Keep away from children and pets." This is not a CLP requirement — it comes from general product safety expectations and industry practice, not from chemical classification rules.

These can appear on the same physical label or on separate labels, but they address different obligations — CLP covers chemical hazard communication, while the safety label covers safe use of the product.

Practical Labelling by Candle Type

Container candles (jars, tins, glasses): The CLP label is typically applied to the side or bottom of the container. Ensure the label is firmly affixed — wax-coated surfaces may need vinyl labels with high-tack adhesive rather than paper labels.

Pillar candles: Apply the label directly to the candle's outer packaging (cellophane wrap, box, or sleeve). If sold unwrapped, a swing tag attached to the candle meets the labelling requirement, provided all six elements are present and legible.

Tea lights: Individual tea lights are often too small for a full CLP label. The label can be applied to the outer packaging (the bag, box, or tray containing multiple tea lights). Each minimum-size pictogram must be at least 10 × 10 mm.

Votives: Similar to tea lights — label the outer packaging rather than the individual votive if the product is too small.

Wax melt clamshells: The label can go on the back of the clamshell packaging. Ensure the label is visible when the package is in its normal retail position.

The "Contains" Line

If your candle is classified for certain health hazards (skin sensitisation is the most common), you must list the specific chemical substances that trigger the classification on the label. This is the "contains" line.

Example: "Contains: linalool, limonene, coumarin"

These must be the chemical names of the hazardous components, not the fragrance oil's trade name. "Contains: Lavender Fragrance Oil" does not satisfy this requirement.

Your fragrance oil supplier's SDS (Section 3) lists the hazardous components and their concentrations. Cross-reference with your product's classification to determine which substances must appear on the label.

One Label per Formulation

Each unique formulation requires its own classification and label. If you sell a lavender candle and a vanilla candle, they use different fragrance oils with different hazard profiles — each needs its own CLP label.

The exception: if two products use the exact same fragrance oil at the exact same concentration in the exact same wax base, their classification will be identical and the label can be the same (apart from the product name).

Fragrance load matters too. The same fragrance oil at 6% versus 10% may produce different classifications because the hazardous component concentrations in the finished product change.
