One question, one answer

Short pages for the questions makers actually ask, each answered from its sources, with the article named where a law is behind it. Each one links to the tool that goes with it.

• Do wax melts need a CLP label?Yes, when the melt is classified as hazardous at your fragrance load or needs the EUH208 line. What decides that, what the label carries, EU and GB CLP.
• Do I need a UFI to sell candles in the UK?Not in Great Britain since 1 January 2024. In Northern Ireland and the EU, yes for a candle classified for a health or physical hazard. How to get one.
• Do I need a UFI to sell candles in the EU?Yes, for a candle classified for a health or physical hazard, H317 included. How to get one, where it goes, and when several scents can share one.
• Does my home address have to be on a candle label?CLP asks for the supplier's name, address and phone number, and the supplier is you. Which address, what can move to a tag on small packs, the 2026 EU rule.
• Does changing the fragrance load change the CLP label?It can. Classification follows the percentage of each hazardous substance, so a new load can add or drop hazards. The limits, the tolerance table, what to ask.
• CLP labels for a custom blend of fragrance oilsA blend of fragrance oils is a new mixture with its own classification that neither supplier's document covers. Why two labels do not add up, and what does.
• Where does the CLP label go on wax melts?On the packaging that immediately contains the melts. Clamshells, bags in boxes, gift sets, tags for tiny packs, 125 ml exemptions and the EU 2028 format rules.
• Can I rename the fragrance on a CLP label?Yes. The trade name on a CLP label is your product's name, not the supplier's scent name. What cannot change: the Contains line and names Article 25(4) forbids.
• How do I list a fragrance oil on a soap label?As "Parfum" in its weight position, plus each declarable allergen over the threshold, by its Annex III name. The arithmetic and the EU, GB and US lists.
• Fragrance allergen calculator for soap and cosmeticsEnter your fragrance's allergen percentages and how much of it you use, and see which substances must be named on the label, on the current EU or UK list.
• Do you need a barcode to sell handmade products?No label rule for soap, cosmetics, candles or food asks for one; shops and marketplaces may. When you need a barcode, and why the number must come from GS1.
• Do I have to list sodium hydroxide on a soap label?Article 19 lists ingredients by weight as added, which supports naming Sodium Hydroxide; the common convention names the salts instead. Both readings compared.
• Selling handmade soap into the EU from the UK: the labelAn EU responsible person, an EU notification, the 80-plus allergen list, no HICC, and the buyer's language. Germany as the worked example, language rule cited.
• Melt-and-pour and liquid soap labels: what to listThe base's INCI list plus what you add, in weight order: every substance in the base is an ingredient. Fragrance, colour, and potassium names for liquid soap.
• Does an online-only shop still need a label on the soap?Yes. Article 19 puts the label on the container and packaging, whatever the sales channel. What may sit on the packaging alone, and the rules for loose bars.
• Can I say "natural" or "chemical-free" on a soap label?"Natural" has no legal definition and must pass the six common criteria for cosmetic claims; "chemical-free" fails the truthfulness test. The EU and GB rules.
• Do I have to emphasise allergens on a home bakery label?On a prepacked or prepacked-for-direct-sale label, yes: each of the 14 Annex II allergens in a typeset that stands out from the list. What loose food needs.
• Reed diffuser and room spray labels: what CLP asks forThe same label elements as a candle, plus what the classification often adds: flammability, aspiration hazard, a child-resistant cap and a tactile warning.
• Do candles at craft fairs or as gifts need a CLP label?Yes when the candle is classified or needs the EUH208 line: giving it away is still placing it on the market. Where the label goes on jars, wraps and sleeves.
