Small-scale chemical producers are still bound by the same legal labelling obligations as large manufacturers. Under the Classification, Labelling and Packaging (CLP) Regulation, all hazardous chemical mixtures placed on the market must carry clear, accurate, and compliant labels—regardless of batch size. This includes cleaning products, cosmetics, industrial solutions, and handmade formulations sold online.
Getting CLP labels right is crucial for legal compliance, customer safety, and business credibility.
What a CLP Label Must Include
Each label must be firmly affixed to the packaging and include specific elements in a standardised format:
- Product identifier (chemical name or trade name)
- Hazard pictograms (square, red-bordered symbols showing key risks)
- Signal word (“Danger” or “Warning”)
- Hazard statements (e.g. “Causes serious eye irritation”)
- Precautionary statements (e.g. “Wear protective gloves”)
- Supplier details (name, address, and telephone number)
- Nominal quantity (for consumer products)
The font must be legible, and pictograms must be at least 1 cm² in size. For containers under 125ml, reduced labelling may apply, but hazard communication must remain clear.
Challenges for Small-Batch Producers
For microbusinesses and hobbyists moving into commercial production, CLP compliance can feel overwhelming—especially without in-house regulatory support. What seems like a simple product may contain ingredients that trigger complex classification rules.
Common challenges include:
- Identifying correct hazard classifications for complex mixtures, particularly when raw material suppliers provide incomplete or unclear safety data
- Generating compliant wording for hazard and precautionary statements, which must follow strict phrasing rules set by the regulation
- Printing constraints on small or oddly shaped containers, where space limits how much information can be displayed clearly
- Balancing branding with regulation, as visually appealing designs must not obscure or minimise required hazard information
There is little room for interpretation or exceptions. Even handmade, natural, or plant-based products must comply fully if they contain any classified substances, including essential oils or preservatives. Failure to label correctly can lead to product recalls, fines, or bans from online marketplaces.
Tools and Resources
To simplify the labelling process, review safety data sheets (SDS) for each ingredient to determine classification. CLP label generators from chemical safety software can help ensure all required elements are correctly formatted.
The European Chemicals Agency (ECHA) offers clear guidance documents and examples, which can be especially useful for interpreting classification rules. If your mixture contains ingredients with unclear or conflicting data, consider working with a consultant who specialises in chemical compliance to avoid costly mistakes.
When it comes to producing the labels themselves, it’s often helpful to use a professional printer experienced in regulatory labelling. Alternatively, durable blank labels can be printed in-house using thermal transfer or laser printers, allowing for easy updates as formulations or regulations change.
Tips for Practical Compliance
Maintain clear records of your formulations, safety data sheets, and each version of your labels. Test label durability if your products are used in harsh environments, and update labels promptly whenever your formulation or supplier details change. If traceability matters, include batch numbers on your packaging.
Be proactive – CLP compliance may be reviewed during inspections, customs checks, or in response to complaints. Clear, accurate labelling protects your business and strengthens customer confidence, whether you’re trading locally or expanding into larger markets.
