Check Your CLP Label Compliance

What Is CLP Label Compliance?

CLP stands for Classification, Labelling and Packaging — the UK regulation that governs how chemical products are identified and communicated to consumers. If you sell candles, wax melts, reed diffusers, room sprays, or any product containing fragrance oils or essential oils, your products are classified as chemical mixtures and must carry CLP-compliant labels before being placed on the market.

A compliant CLP label communicates the hazards associated with a product in a standardised way. It includes GHS hazard pictograms (the red diamond symbols), a signal word indicating severity, hazard and precautionary statements describing the risks and safe handling, supplier identification, a product name, and a list of key hazardous ingredients. These elements are not optional — they are a legal requirement under UK law, and trading standards officers actively enforce compliance.

What This Checker Assesses

This tool checks whether the essential visual and textual elements required by CLP regulation are present on your label. It covers the six required elements — GHS pictograms, signal word, hazard and precautionary statements (H-codes and P-codes), supplier details, product identifier, and nominal quantity — plus the “Contains” line listing allergens or hazardous ingredients. The assessment is based on your self-reported answers.

What to Do If Elements Are Missing

If the checker flags missing elements, you need to address those gaps before continuing to sell the product. Start by obtaining the Safety Data Sheets (SDS) for every fragrance oil and essential oil in your formulation — these contain the hazard classification data needed to determine the correct statements and pictograms.
