Create a Caution or Warning Label
Quick answer: Choose your product category, tick the standard warnings that apply, add your business details, then download a round or rectangular label as PNG or a print-ready PDF sheet. Warnings are built from checkboxes rather than free typing, so the wording stays clean and consistent with commonly used industry phrasing.
This generator provides commonly-used, industry-standard warning wording to help you lay out a label - it does not guarantee compliance with any specific country, state, or platform's regulations, and requirements can change over time.
Candle, cosmetic, and consumer product labelling rules vary by market (for example, US guidance and EU/UK requirements are not identical) and by exactly what is in your product. Before selling, verify current requirements with your local regulatory authority, trade association, or a qualified compliance professional - especially for fire-safety and ingredient-related claims.

✨ Why a Clear Warning Label Matters
Beyond any regulatory expectation, a clear caution label is one of the simplest things a small maker can do to reduce risk - to a customer's home, and to their own business. It also signals to buyers that a handmade product was made by someone who takes it seriously.
Candle Makers
Add standard fire-safety wording to jars, tins, and lid stickers.
Wax Melt & Warmer Sellers
Clarify that a product is for warmers only, not for direct flame.
Soap & Bath Product Makers
Add external-use-only and patch-test wording to bars, bombs, and salts.
Jewelry & Accessory Sellers
Flag choking hazards and material care notes on packaging inserts.
Textile & Apparel Makers
Print wash and care instructions for handmade garments and totes.
Wood & Furniture Crafters
Include cleaning and care guidance for finished wood pieces.
🔎 Anatomy of a Candle Caution Label
- Never leave burning candle unattended
- Keep away from children & pets
- Trim wick to 1/4 inch before burning
- Keep away from drafts

Candle Caution Labels — A Practical Guide for Makers and Small Shops
If you sell candles, wax melts, or bath products - on Etsy, at a market stall, or through your own shop - a caution label is one of the smallest pieces of packaging that carries the most weight. It's also one of the easiest things to get wrong by accident: copying wording from a competitor's label, forgetting a standard warning, or typing something slightly different each time you print a new batch. This guide covers what these labels typically include, how this generator builds them, and where the real regulatory lines sit - along with a clear reminder that formatting a label and confirming legal compliance are two different things.
What "ASTM F2417" Actually Refers To
ASTM F2417 is the common shorthand within the US candle industry for a voluntary consensus standard addressing fire-safety aspects of candles, developed through ASTM International with input from candle manufacturers, testing labs, and safety organisations. It's frequently cited alongside general public safety guidance from the US Consumer Product Safety Commission (CPSC) on safe candle use. In practice, this is where familiar phrases like "never leave a burning candle unattended" and "keep away from children and pets" originate as industry-standard, widely recognised wording - not because any single sentence is dictated word-for-word by law in every jurisdiction, but because this phrasing has become the accepted baseline for candle safety communication. This tool's candle warning checklist reflects that widely-used baseline phrasing so you're not reinventing it from scratch for every product.
How This Generator Actually Works
Your label is drawn entirely with the Canvas API in your browser, and nothing about your product, business name, or selected warnings is ever transmitted anywhere. When you select a product category, a pre-written checklist of commonly-used warnings for that category appears; ticking a box adds that exact sentence to your label, so wording stays consistent rather than being retyped and potentially altered each time. As you select more warnings, the tool measures the total text height required and automatically scales the warning list, headline, and pictogram row down proportionally if needed, so the content always fits the label size you've chosen without manual trial and error. Round label shapes are rendered using a true circular canvas clip, so the exported PNG has a transparent background outside the circle - ready to sit cleanly on a lid or jar without a visible square edge.
Why This Isn't (and Can't Be) a Compliance Guarantee
This is worth being blunt about. Product labelling requirements are set by regulators, differ by country and sometimes by state or region within a country, apply differently depending on your product's exact ingredients or construction, and change over time as standards are updated. A generic tool - this one included - cannot know which specific rules apply to your product, your ingredients, or the exact market you're selling into, and it isn't a substitute for checking current official guidance or consulting a professional where the stakes are meaningful (fire safety, allergen disclosure, and children's product rules are the areas where getting it wrong carries the most real-world risk). What this tool can do reliably is help you lay out commonly-used, industry-recognised phrasing cleanly and consistently, so you're not starting from a blank page or copy-pasting from an unverified source each time.
US vs EU/UK: A General Comparison (Not Legal Advice)
🇺🇸 US-Focused Considerations
- Candle fire-safety wording commonly informed by ASTM F2417-aligned industry practice
- CPSC publishes general consumer safety education on candle use
- Cosmetic-adjacent products (soap, bath items) may fall under FDA labelling expectations depending on claims made
- State-level rules can add further requirements (for example, certain warning statements in some states)
🇪🇺🇬🇧 EU/UK-Focused Considerations
- Candle safety often referenced against EN standards covering candle specification and fire safety
- Cosmetic-adjacent products generally fall under EU Cosmetic Regulation-style frameworks, often requiring an ingredient (INCI) list and fragrance allergen disclosure
- CLP-style hazard classification and labelling principles may apply depending on formulation
- UK post-Brexit rules broadly mirror EU principles but should be checked separately for UK-specific market requirements
This comparison is general educational context, current at the time of writing, and is not a complete or authoritative summary of either region's requirements. Standards referenced by name (ASTM, EN, CLP, FDA, CPSC) belong to their respective organisations - always consult official sources directly.
Choosing the Right Label Shape and Size
| Size/Shape | Best For | Why |
|---|---|---|
| 50mm Round | Standard candle jar lids | Common lid diameter for 8-9oz candle jars |
| 63.5mm Round | Larger candle jars and tins | Fits bigger lids while keeping the full warning list legible |
| 76 x 38mm Rectangle | Side-of-jar labels, tin bottoms | Standard small-label footprint, easy to source pre-cut stock for |
| 195 x 50mm Jar Wrap | Wrapping fully around a jar | Long enough to circle a standard jar while including branding and warnings together |
| 40 x 25mm Sticker | Wax melt clamshells, small tins | Compact size for products with limited surface area |
Choosing the Right Category
Printing Tips for Small Labels
- Weatherproof stock for candles: Wax and heat can cause standard paper labels to yellow or peel - a matte vinyl or waterproof label stock holds up far longer on a candle jar.
- Test one before a full sheet: Small text on a 40mm sticker is the first thing to become unreadable if your printer's DPI settings aren't set correctly - check a single print before committing a full batch.
- Keep round labels centred: When hand-applying round lid labels, a simple centring guide or template helps avoid an off-centre, unprofessional look.
- Batch/lot numbers aren't just for compliance: They also make it much easier to trace a specific wax or fragrance batch if a customer ever reports an issue.

Troubleshooting
The auto-fit system shrinks text proportionally when many warnings are selected on a small label - try deselecting less essential warnings, adding a custom shorter combined line, or choosing a larger label size.
Make sure you're downloading the PNG (which preserves transparency) rather than viewing a screenshot - the PDF export places the image on a white page by design, which is normal for print.
This tool cannot tell you which warnings are legally required for your specific product and market - it only offers commonly-used phrasing as a starting point. Check official guidance or consult a professional for your specific situation.
A draft autosaves to local storage after each change, but clearing your browser's site data or using a private/incognito window prevents that draft from persisting.
Frequently Asked Technical Questions
How does the auto-shrink layout work?
The tool measures the wrapped height of every selected warning, the headline, and the footer at full size first; if the total exceeds the available label height, everything is redrawn at a proportionally smaller scale until it fits, rather than truncating or overlapping content.
How are round labels rendered with a transparent background?
The canvas uses a circular clipping path before any background fill is drawn, so colour is only applied inside the circle - the browser canvas is transparent by default outside that clipped region, which carries through automatically to the PNG export.
Where do the pictogram icons come from?
They are drawn using standard emoji characters matched to specific selected warnings (for example, a flame icon for fire-related candle warnings), rendered directly by the canvas text renderer rather than as separate image assets.
