Everything UK wax melt sellers need to know about CLP regulations, SDS sheets and legal compliance — plus direct links to the official UK regulatory guidelines.
Selling wax melts in the UK comes with legal responsibilities. Understanding CLP regulations, safety data sheets and proper labelling is not optional — it's the law. This guide explains what you need to know before you sell.
CLP stands for Classification, Labelling and Packaging — an EU regulation that was retained in UK law after Brexit (UK CLP). It applies to any product that contains hazardous substances, which includes most fragranced wax melts due to the chemical nature of fragrance oils.
If you sell wax melts (even at craft fairs or on Etsy), you must comply with UK CLP regulations. Failure to do so could result in your products being removed from sale or legal action.
⚠️ Key Rule: You cannot sell wax melts without a compliant CLP label. This applies even if you give them as gifts in exchange for payment, sell at markets, or list them online. Homemade does not mean exempt.
Every fragrance oil you use should come with a Safety Data Sheet from your supplier. The SDS contains crucial information including:
Always request SDS documents from your fragrance supplier and keep them on file. Reputable UK suppliers like Candle Shack, Craftovator and Fragrance Oil Studio provide these automatically.
A compliant wax melt label must include:
Tick these off for each product with our CLP label checklist.
Several UK-based CLP label services exist to help small makers generate compliant labels. These include Soapbox (soapbox.co.uk), Create Cosmetics and various fragrance suppliers who offer CLP label generation as part of their service.
The International Fragrance Association (IFRA) sets maximum usage rates for fragrance ingredients based on the product category. For wax melts (Category 12 — air fresheners), these limits define the maximum percentage of fragrance oil you can safely use.
⚠️ Action Required — IFRA 51st Amendment: The IFRA 51st Amendment took effect on 30 October 2025. All fragrance oils you use must now have certificates referencing the 51st Amendment. Older 49th or 50th Amendment certificates are no longer sufficient — contact your fragrance suppliers now to request updated SDS and IFRA compliance documents for every scent in your range.
Some ingredients previously permitted have had their maximum usage rates reduced under the 51st Amendment. If you are still using fragrance oils with outdated certificates, your products may be out of compliance and carry legal risk.
Before selling any wax product, take out appropriate product liability insurance. This protects you if a customer makes a claim related to your products. Several UK insurers offer specific craft maker policies at reasonable annual premiums.
The Product Regulation and Metrology Act 2025 received Royal Assent on 21 July 2025. It is a framework law: it gives the government powers to make new product safety regulations over time, rather than setting out new rules itself.
Until those regulations are made, the General Product Safety Regulations 2005 still apply to candles and wax melts, alongside GB CLP. For most small makers, day-to-day obligations are unchanged for now, but watch for new regulations from the Office for Product Safety and Standards (OPSS) as they are introduced.
If you sell to EU customers — through Etsy, your own website, or at cross-border markets — additional requirements apply. UK and EU regulations have diverged since Brexit; EU rules do not apply within the UK, but they do apply to any products you place on the EU market.
The EU's General Product Safety Regulation came into force on 13 December 2024, replacing the old General Product Safety Directive. It introduces more detailed risk assessment requirements covering chemical, inhalation, fire and physical hazards. Online marketplaces are now co-responsible for product safety, meaning platforms like Etsy can be held accountable for non-compliant listings. UK sellers shipping to EU customers need GPSR-compliant risk documentation for their products.
From 1 January 2025, any hazardous mixture placed on the EU market must display a UFI code (Unique Formula Identifier) on the label — a 16-character code linked to a Poison Control Notification submitted to ECHA. Each distinct fragrance formula requires its own notification. This applies to fragranced wax melts classified as hazardous under CLP. UK-only sellers do not need UFI codes on domestic labels, but it is mandatory for anything sold into EU countries.
Commission Regulation (EU) 2023/1545 expands the list of fragrance allergens that must be named individually on cosmetic products from about 26 to more than 80. New cosmetics placed on the EU market must comply from 31 July 2026, and all cosmetics on sale from 31 July 2028. It amends the EU Cosmetics Regulation, so it affects bath and body products such as bath bombs, not wax melts. Allergen statements on wax melt labels still come from CLP (the "Contains … May produce an allergic reaction" wording). The UK has not adopted the expanded cosmetics list, so UK and EU cosmetic labels may need to differ.
Northern Ireland follows EU CLP rather than GB CLP. If you post hazardous wax melts to customers there, GOV.UK guidance says you must submit product information to the poisons service and put a UFI on the label. Neither is required for sales in England, Scotland and Wales.
If you describe your wax melts to EU customers using terms such as "eco-friendly," "natural," "clean-burning," "non-toxic" or "sustainable," the EmpCo Directive (EU 2024/825) applies from September 2026. It bans generic, unsubstantiated environmental claims. Offset-based "carbon neutral" claims are also prohibited without independent substantiation.
UK sellers marketing domestically are not currently subject to an equivalent law, but Trading Standards can still act on misleading claims under the Consumer Protection from Unfair Trading Regulations. If you market a wax as "natural" or "eco-friendly," be specific about what that means — for example "made from 100% UK-grown rapeseed wax" rather than a vague sustainability claim.
📋 Checklist before selling: ✓ SDS on file for every fragrance ✓ CLP label on every product ✓ IFRA 51st Amendment certificate confirmed ✓ Product liability insurance in place ✓ Allergen disclosure up to date ✓ If selling to Northern Ireland or the EU: UFI code on label + poison centre notification submitted. Work through the full CLP label checklist.
