Do wax melts need a CLP label?

Published 21 September 2026; rules last checked 25 September 2026. A labelling reference, not legal advice.

Yes, if the melt classifies as hazardous at the fragrance percentage you use, or needs the EUH208 line, and it is sold in packaging. That is the test Article 17(1) of CLP applies to any classified mixture, with Article 25(6) and Annex II, section 2.8 adding the EUH208 case, and a scented wax melt is a mixture: wax plus fragrance oil, plus dye if you add it. Whether yours classifies is decided by your fragrance supplier's classification data at your percentage, not by the fact that it has no wick. The same text applies in Great Britain under GB CLP.

Why a wax melt is covered

CLP applies to mixtures, and Article 2(8) defines a mixture as one composed of two or more substances. Article 4(4) then says that where a mixture is classified as hazardous, suppliers must ensure it is labelled and packaged in accordance with Titles III and IV before placing it on the market, and Article 17(1) lists what that label carries. "Placing on the market" is defined in Article 2(18) as supplying or making available, whether in return for payment or free of charge, to a third party, so a sample, a gift or a swap counts as much as a sale.

Nothing in those articles distinguishes a candle from a melt. A candle has a wick and a melt does not, but the wax and fragrance are the same kind of mixture, and the question is only ever whether that mixture is classified.

What decides whether it classifies

Your fragrance supplier's CLP data or safety data sheet gives the classification of the fragrance in wax at one or more percentages. Three outcomes are common for scented wax:

• Skin sensitisation (H317). Annex I, section 3.4.3.3.1, says a mixture is classified as a skin sensitiser when at least one ingredient classified as a skin sensitiser is present at or above the limit in Table 3.4.5: 1,0 % for a category 1 or sub-category 1B sensitiser, 0,1 % for sub-category 1A. That means the pictogram (GHS07), the signal word "Warning" and H317 on the label.
• EUH208 without a pictogram. Annex II, section 2.8, applies to a mixture that is not classified as sensitising but contains a sensitiser at or above the lower limit in Table 3.4.6: 0,1 % for category 1 or 1B, 0,01 % for 1A. Its label must carry "EUH208 Contains (name of sensitising substance). May produce an allergic reaction." So a melt with no pictogram can still need a label, and "no pictogram" is not the same as "no label".
• Aquatic hazards. Many fragrance materials are classified as hazardous to the aquatic environment. Chronic 1 and 2 add the GHS09 pictogram and H410 or H411; chronic 3 (H412) adds a statement with no pictogram.

Because the limits are percentages of the finished product, a melt poured at 10 % fragrance can classify where the same fragrance at 6 % in a candle did not. The supplier's document for the percentage you actually use is the input; the label follows from it.

What goes on the label

Article 17(1) requires, for a classified mixture: the supplier's name, address and telephone number; the nominal quantity; the product identifiers; and, where applicable, the hazard pictograms, the signal word, the hazard statements, the precautionary statements and a supplemental information section, which is where EUH208 and, in the EU and Northern Ireland, the UFI go. The EU and UK candle CLP guides walk through each element and the sizes. One rule applies before you name a product: Article 25(4) bans "non-toxic", "non-harmful", "non-polluting", "ecological" and any other statement indicating that the mixture is not hazardous, anywhere on the label or packaging.

Where melts differ from candles

• The package carries the label, not the melt. A clamshell, a bag or a box is the packaging that immediately contains the mixture, and that is where Article 31(1) puts the label. Multi-melt boxes and tiny packs have their own rules; see where the CLP label goes on wax melts.
• Small packs may drop some statements, never H317. Only where the full label cannot be given even on a tie-on tag or an outer pack (Article 29(2)), a package of 125 ml or less may leave out, under Annex I 1.5.2.1, the hazard and precautionary statements for skin and eye irritation and for aquatic acute 1 and chronic 1 or 2; for aquatic chronic 3 or 4 (H412, H413) only the precautionary statements may go. Skin sensitisation is not on either list, so H317 and its precautionary statements stay however small the pack. The details are on where the CLP label goes on wax melts.
• The percentage is usually higher. Melts are commonly poured at a higher fragrance load than candles, which is exactly the situation where the classification can change. See does changing the fragrance load change the label.
• The UFI rule is regional. EU and Northern Ireland: a UFI when the melt is classified for a health or physical hazard. Great Britain: none. See do I need a UFI in the EU and in the UK.

When a melt does not need one

A melt that is not classified as hazardous, and that does not trigger EUH208, falls outside Article 17(1). Plain unscented wax on its own has nothing to classify. The moment fragrance goes in, the question is answered by the supplier's data at your percentage, and the safe habit is to treat "no CLP label needed" as a conclusion you can point to in that document, not an assumption.
