Understanding CLP Compliance for Essential Oil Products in the UK

If you make or sell essential oil products in the UK, you will have come across the letters CLP. They stand for Classification, Labelling and Packaging, and the rules sit behind every warning pictogram you see on a bottle of essential oil. Getting them right protects your customers, keeps your listings compliant and builds trust with wholesale buyers who will ask to see your paperwork.

This guide covers the basics for essential oil products such as pure oils, oil blends, room sprays and fabric sprays. If you make candles, our guide to UK CLP compliance for candle makers covers the points that are specific to wax products.

What is GB CLP?

GB CLP is the regulation that controls how hazardous substances and mixtures are classified, labelled and packaged in Great Britain. It is enforced by the Health and Safety Executive (HSE) and Trading Standards. If your product contains essential oils at a concentration that triggers a hazard classification, the label has to say so.

Why essential oils often need hazard labelling

Natural does not mean exempt. Many essential oils and their components carry hazard classifications. The ones that come up most often are:

• Skin sensitisation and irritation, common with citrus, clove, cinnamon and many floral oils.
• Hazardous to the aquatic environment, which applies to a large number of oils and is one reason you see the environment pictogram so often.
• Flammable liquid, relevant for oils and alcohol-based sprays.
• Aspiration hazard, which affects oils high in certain terpenes.

A blend is classified as a mixture, so the classification depends on what is in it and at what concentration. You cannot simply copy the label from one of your ingredient oils.

What a compliant label includes

• Product identifier, meaning the product name
• The relevant hazard pictograms
• The signal word, either Warning or Danger
• Hazard statements and precautionary statements
• Supplier name, UK address and telephone number
• Nominal quantity, such as 10ml or 100ml
• Any supplemental information required for the product

There are also rules on minimum label size and pictogram size that depend on the container volume. Small bottles have some allowances, so check the current HSE guidance for your pack sizes.

Safety data sheets

Professional and wholesale customers, such as candle makers and soap makers, will usually expect a safety data sheet (SDS) with every blend. The SDS gives the classification, handling and storage advice, first aid measures and disposal information. If you buy oils from a supplier, ask for their SDS, but remember that your finished blend needs its own.

Practical steps before you sell

1. Get the safety data sheet for every raw material you use.
2. Classify each finished blend or spray as a mixture, based on the composition.
3. Create a label that includes every required element, and check it against the current HSE guidance.
4. Check whether your products need to be notified to the poison centres, as HSE has been rolling out notification requirements for hazardous mixtures.
5. Keep your documents together so you can supply an SDS or answer a Trading Standards query quickly.

Do I need help?

For a simple single oil the process is manageable. For blends, large ranges or products you plan to export, it is worth speaking to a compliance consultant or your local Trading Standards office. This article is general information, not legal advice, and the regulations change, so always check the latest guidance at gov.uk and on the HSE website.
