Do I need a CLP label on wax melts if I only sell at craft fairs?

Yes. CLP applies whenever you supply a hazardous mixture to the public, whether that's online, at a fair or to friends for money. Scented wax melts usually need at least an allergen statement, and often pictograms and hazard statements, depending on the fragrance oil and how much you use.

Do I need a UFI code on wax melt labels in the UK?

Not in Great Britain. GOV.UK guidance says there is no obligation to generate a UFI for the GB market. Northern Ireland follows EU CLP, so if you sell hazardous wax melts to customers there, a UFI on the label and a poison centre notification are required, as they are for EU customers.

Where do I get the hazard statements for my label?

From your fragrance supplier. Most UK suppliers publish CLP information for each oil at common loads, such as 10%, or give you the Safety Data Sheet so the classification can be calculated. Use the information for the load you actually use. If it is only given for a higher load, that is the cautious choice; never use figures for a lower load than yours.

Does my label need a phone number?

Yes. A CLP label must give the supplier's name, address and telephone number. It is one of the most commonly missed items on handmade wax melt labels.

Wax Melt CLP Label Checklist (UK)

Use this checklist when you design a label, add a new scent or change your fragrance load. It covers what has to be on a CLP label in Great Britain, the documents behind it, and the extra rules if you post to Northern Ireland or the EU. Your ticks are saved in this browser.

This is a checklist, not legal advice. What your label must say depends on your exact fragrance oil and load, and that information comes from your fragrance supplier. If you're unsure, ask your local Trading Standards service or see Business Companion's guidance on candles and similar products. For the background, read our CLP & compliance guide.

Before you label

Your label is only as good as the information behind it. Get these for every fragrance oil and colour you use.

I have a current Safety Data Sheet (SDS) for every fragrance oil and colourantThe SDS lists the hazardous ingredients your classification is based on, plus the flash point. HSE NI says the information to classify a candle "should be available in the SDS provided by the suppliers of fragrances or colourants". Keep them on file.
I have an IFRA certificate for each oil, and my load is within its Category 12 limitWax melts and candles are IFRA Category 12. The certificate should reference the 51st Amendment; its restrictions applied to existing fragrances from 30 October 2025.
I have CLP label information for each oil at the load I actually useClassification depends on how much oil is in the finished melt. Use your supplier's CLP information for your load. If it's only given for a higher load, that's the cautious choice; never use figures for a lower load than yours. Use the fragrance load calculator to confirm your percentage.
If I blend oils, the label covers the blend, not just one of themEach oil brings its own allergens, so a blend can need statements that neither oil needs on its own label. Ask your supplier, or a CLP labelling service, for the blend at your total load.

Label format

The label reads horizontally when the pack is set down normallyHSE NI: the label "must be easily readable horizontally when the package is set down normally".
It's firmly stuck on, and the print won't rub off or smudge with wax or oilTest a label on a clamshell that has sat on a warm shelf. Fragrance oil can lift some sticker adhesives and make inkjet print run.
If my pack is too small for everything, I've checked the small-packaging optionsCLP allows some alternatives for very small packs, such as fold-out labels or tie-on tags. Check with your label supplier or Trading Standards before relying on one.

Safe use and records

Safe-use warnings are on the pack or insertFor example: never leave a lit warmer unattended; keep away from children, pets and things that can catch fire; use on a heat-resistant surface. Candles have a specific warning-label standard (BS EN 15494), and Business Companion lists it among the standards that apply to candles.
I keep records of each batch: oil, supplier, load and dateIf a customer reports a problem, you can find which oil and SDS apply. The batch log does this for you.
I have product liability insuranceNot a CLP requirement, but strongly recommended before you sell any wax product, and many craft fairs ask for it.
I re-check labels when I change an oil, a supplier or my loadA new batch of the "same" scent from a different supplier can have a different classification.

If you post to Northern Ireland or the EU

Skip this section if you only sell in England, Scotland and Wales.

For Northern Ireland: a UFI on the label and a poison centre notification, if the melt is classified as hazardousNorthern Ireland follows EU CLP. GOV.UK guidance says that for hazardous mixtures placed on the NI market, submitting information is required and "you must also include a UFI … on the label or packaging". In Great Britain neither is required.
For EU customers: EU CLP labelling, a UFI and a poison centre notification, plus EU GPSR responsibilitiesSee the "Selling into Europe" section of our CLP & compliance guide.
