CLP Labelling for Candles and Wax Melts: The Complete UK Guide

By Tamar Mayne, Home Fragrance Academy

If you make and sell candles or wax melts in the UK, CLP labelling isn't optional. It's the law. And yet it's one of the areas where we see the most confusion - and the most costly mistakes - among new home fragrance makers.

This guide covers everything you need to know about CLP labelling for candles and wax melts in the UK: what it is, what must appear on your label, which products need one, and the most common mistakes that could invalidate your insurance or land you in trouble with Trading Standards.

We've built three home fragrance brands - Cosy Aromas, Craft HQ and Waxkind - generating over £7.5 million in sales. CLP compliance has been part of our business from day one, and it's something we teach inside Home Fragrance Academy to over 1,100 makers across the UK.

Let's get into it.

What Is CLP Labelling?

CLP stands for Classification, Labelling and Packaging. It refers to the legislation - originally EU Regulation (EC) No 1272/2008 - that requires products containing hazardous chemicals to be correctly labelled so that anyone handling or using them understands the risks.

For candle and wax melt makers in the UK, the relevant guidance post-Brexit remains closely aligned with the original ECHA (European Chemicals Agency) framework. The requirements haven't changed in any meaningful way for small UK makers, so if you've seen people online claiming otherwise, you can set that aside.

The short version: if your product contains fragrance oil or essential oils of any percentage, it needs a CLP label. That applies whether you're selling at a market stall, through your own website, on Etsy, or gifting products to friends and family.

Yes - even gifting. If you're giving away products containing fragrance oils, CLP still applies.

Which Products Need a CLP Label?

Any home fragrance product containing fragrance or essential oils must have a CLP label affixed. This includes:

• Candles
• Wax melts
• Room sprays
• Reed diffusers
• Scented sizzlers
• Snow wax
• Carpet fresheners
• Fragrance oils (sold as products)

The wax itself is not hazardous - it's the fragrance or essential oil that triggers the CLP requirement. So an unscented candle wouldn't require a CLP label, but virtually every product you're likely to sell will contain some level of fragrance oil.

What Must Appear on a CLP Label?

This is where many makers go wrong. Under CLP legislation (Article 17), your label must include the following:

1. Product Identifier

The name of your product or fragrance - clearly stated so the customer knows what they're buying.

2. Signal Word

Either "Warning" or "Danger" - which one you use depends on the hazard classification of the specific fragrance oil you're using. This information comes from the Safety Data Sheet (SDS) provided by your fragrance oil supplier.

3. Hazard Pictograms

The recognised symbols that communicate the type of hazard, such as flammability, skin irritation, or environmental harm. These must meet minimum size requirements. A common mistake is printing them too small to be legible. If a customer or emergency service can't read your label at a glance, it's non-compliant.

4. Hazard Statements

Short, standardised phrases that describe the nature of the hazard. For example: "May cause skin sensitisation." Again, these come directly from your SDS sheet.

5. Precautionary Statements

Instructions for safe handling, storage, and disposal. These are drawn from the SDS and must not be omitted or reworded.

6. Allergen Information (Contains Section)

If your fragrance contains allergens above certain concentration thresholds, these must be listed. What appears here - and whether it appears at all - depends entirely on the specific fragrance oil and percentage used.

7. Supplier Information: Name, Address, and Phone Number

This is one of the most misunderstood requirements, and one of the most commonly got wrong.

You must include a contact telephone number. An email address is not sufficient.

We see this come up constantly in maker communities - people saying they've used an email address instead, or left the phone number off because they don't want their personal mobile number on their products. The legislation is clear: a phone number is required for emergency situations. It exists so that if someone is injured or has a reaction, emergency services or Poison Control can reach the responsible party.

The solution is simple: get a pay-as-you-go SIM. Use that number on your labels. It doesn't have to be your personal number.

Every CLP Label Is Unique

This is something that trips up a lot of new makers: you cannot use the same CLP label across different products or different fragrance oils.

Every fragrance oil has its own Safety Data Sheet. The hazard classification, pictograms, signal word, hazard statements, and allergen information all vary depending on the specific chemicals in that fragrance. Even the same scent from two different suppliers will have different SDS documents - and therefore different CLP labels.

This is why it's essential to obtain the SDS from your specific fragrance oil supplier for every single oil you use, and to generate a CLP label from that SDS.

What Is a Safety Data Sheet (SDS)?

An SDS - sometimes called an MSDS - is a document provided by your fragrance oil supplier that contains detailed information about the chemical composition of the oil, including any hazardous substances and their concentrations.

Every reputable supplier will have SDS sheets available for their fragrance oils, usually downloadable from their website or available on request. If a supplier cannot provide an SDS for a fragrance oil, that's a serious red flag.

Your CLP label is built from the information in the SDS. This is why you cannot simply copy someone else's label, use a generic template, or take advice from Facebook groups where no one has seen your SDS.

CLP and Your Website

If you're selling online, your CLP obligations don't begin and end with the physical label on your product.

Under the regulations, CLP information must be available to the customer before they complete their purchase. This means the hazard information - allergens in particular - should be accessible on your product pages.

Think about a customer with a known allergy. They need to be able to make an informed decision before they buy, not just when the product arrives. If your website doesn't make this information available, you're non-compliant even if your physical labels are perfect.

The Biggest CLP Mistakes We See

After working with over 1,100 home fragrance makers inside Home Fragrance Academy, these are the mistakes Tamar sees most often:

Mistake 1: Using an Email Address Instead of a Phone Number

Covered above, but worth repeating. An email address does not satisfy the legal requirement. You need a telephone number.

Mistake 2: Pictograms That Are Too Small

There are minimum size requirements for CLP pictograms. If you're printing on a small label or using a very small font size, your pictograms may not meet the required dimensions. A label that can't be read in an emergency situation isn't compliant - regardless of whether the right information is technically there.

Mistake 3: Taking CLP Advice from Facebook Groups

This deserves its own section.

Why Facebook Groups Are the Wrong Place for CLP Advice

Maker communities on Facebook can be brilliant for supplier recommendations, recipe ideas, and general business support. But they are consistently one of the worst places to seek CLP guidance.

The problem is this: CLP labels cannot be assessed without the corresponding Safety Data Sheet. When someone posts a photo of their label in a group and asks "is this right?", the honest answer is that no one can tell from a photo alone. Without knowing the fragrance oil, the supplier, the percentage used, the product size and composition, it's impossible to give a meaningful answer.

And yet you'll see dozens of confident responses: "That's wrong." "You don't need that pictogram." "The ingredients are missing." Some of these responses will be accurate. Many won't be. The people giving advice are often working from incomplete information or from what they believe to be correct based on their own labels, which may themselves be wrong.

The responsibility for your CLP compliance sits with you as the business owner. If your labels are incorrect and a customer is harmed, or Trading Standards investigates, "someone in a Facebook group told me it was fine" is not a defence.

Go to the source: your supplier's SDS, and the ECHA guidance documentation.

CLP and Your Insurance

This is where things get serious if you're not compliant.

Most product liability insurance policies for candle and wax melt businesses include a requirement that your products are correctly labelled in accordance with relevant legislation. If you're selling products with incorrect or missing CLP labels, you may find your insurance is invalid - meaning if a customer makes a claim against you, you're unprotected.

Given that CLP labels also exist to alert customers to potential allergens and hazards, the consequences of non-compliance can extend well beyond a fine from Trading Standards.

How to Create Your CLP Label

The process, simplified:

1. Obtain the SDS for each fragrance oil from your supplier.
2. Read Section 2 of the SDS - this contains the hazard classification, signal word, pictograms, hazard statements, and precautionary statements for that specific oil.
3. Check the allergen section - typically Section 3 or in the additional labelling information.
4. Build your label including all required elements: product name, signal word, pictograms, hazard statements, precautionary statements, allergen information, and your business name, address, and phone number.
5. Apply the label firmly to the product. It must be readable horizontally when the product is set down.

If you're selling online, make sure the relevant hazard information is also accessible on your product pages before purchase.

The Label Must Be Legible

The regulations don't just cover what information must be present - they also cover how it must be presented.

• The label must be firmly attached to the product
• It must be readable horizontally when the product is in its normal position
• Pictograms must meet minimum size requirements (a white background with a red border and black symbol)
• The text must be in the language(s) of the country where the product is sold

If your label is peeling off in transit, printed too small to read, or positioned so that it faces downward when the product is displayed, it's not compliant.

Where to Get Help

The most reliable sources for CLP guidance are:

• Your fragrance oil supplier - for SDS sheets and any fragrance-specific questions
• The ECHA Guidance on Labelling and Packaging - the primary reference document for CLP compliance, available at echa.europa.eu
• Trading Standards - your local Trading Standards office can provide guidance
• The British Candlemakers Federation (BCF) - a trade body that provides support on compliance issues

Inside Home Fragrance Academy, we run a dedicated short course where Tamar teaches you how to read an SDS sheet, understand what it means, and build your own CLP labels that are fully compliant with current UK legislation. It's one of the most practical things you can do as a maker who wants to trade with confidence.
