Reed diffuser & room spray label generator: CLP and US
Make the label for a reed diffuser or room spray from your supplier's documents for the finished liquid. For the EU, Great Britain or Northern Ireland, pick the CLP classifications its safety data sheet lists and the tool builds the pictograms, one signal word, the hazard statements, the EUH208 line and the UFI rule for your region; an EU label prints in any of 23 EU languages. For the United States, enter its flash point and hazards and the tool builds the Federal Hazardous Substances Act warning, sized for your bottle, with the net contents in both units and the child-resistant packaging rule. Then size the label and export it print-ready. Building and previewing the label is free; you pay only to export it. Selling in the UK? The UK candle CLP guide covers diffusers too.
Your product
Supplier (name, address and phone are all required)
Your business (name and place, on every US label)
The street may be left off only if your address is listed publicly, in a directory or on a website (16 CFR 500.5(c)).
The bottle (it sets the minimum letter heights)
Measure the straight side the label goes on, without the shoulder or neck. For a round bottle the rules count 40 % of the height times the circumference as the front panel (16 CFR 1500.121(c)(1), 500.21(a)).
Hazard classification
Tick every classification your fragrance supplier's CLP / safety document lists for the finished product at your fragrance load. The tool covers the classes listed here. If your document lists one that is not here (for example H361, H373 or EUH066), a label from this tool will be missing it: add that statement, and any pictogram or signal word it brings, to the label yourself.
A picked statement is added in the label's language, in Annex IV's own words, and follows the label when you change its language. Where the text offers a choice ("/"), a blank ("…") or a part in square brackets, edit the line to what applies.
Hazards of the finished product
The US label follows the Federal Hazardous Substances Act, which judges the finished liquid in the bottle, not its ingredients. Tick only what applies to the finished product, from your supplier's documents or a test. A safety data sheet's GHS classes are not the same thing: CPSC says they "can differ" from the Act's, so the tool does not translate them.
The closed-cup flash point of the finished liquid (the method of 16 CFR 1500.43a), not of the fragrance oil or the base alone. At or below 20 °F it is extremely flammable, below 100 °F flammable, up to 150 °F combustible.
Where the rules require DANGER (or WARNING) the tool uses it whatever you pick here.
Child-resistant packaging
A packaging rule, not a label: the Poison Prevention Packaging Act lists the products that need a child-resistant closure (16 CFR 1700.14).
Hydrocarbons are "substances that consist solely of carbon and hydrogen", added up (16 CFR 1700.14(a)(31)): in a diffuser base these are isoparaffins and similar solvents, and in fragrance oils terpenes such as limonene and pinene. Your supplier's composition gives the figures.
Assembled label elements
Print-ready label
Exports are the paid step. Everything else, including the declaration and the notes, is free.
Pictograms are the official UNECE GHS artwork (CLP Annex V), embedded at print resolution and exported in the PDF. Print each at least 10 mm per side (and keep the whole label legible) so it meets the CLP minimum size.
The tool sets every line at or above its legal minimum height for your bottle, and will not download a label that is too small to carry them. The warning sits in a ruled box, as the rules want it set apart from the rest of the label.
Saved designs
Designs save in this browser, and to your account when signed in. An uploaded logo is not part of a saved design; add it again after loading one.
Low contrast between sticker and text (under 3:1). A hazard label has to be legible; pick a darker text or a lighter sticker.
From 1 January 2028, the text of a hazard label for the EU or Northern Ireland must be black on a white background, in a single font without serifs, with lines at least 120% of the font size apart (CLP Annex I, section 1.2.1.5, added by Regulation (EU) 2024/2865). This label's font has serifs or its colours are not black on white; until then the choice is yours.
Front label
Back label
Print several on one sheet (A4 or US Letter)
For printing at home: copies of this label on one page, to cut out along the marks or to print onto a sheet of ready-cut labels.
Print it at 100 % ("Actual size"), not "Fit to page". Try one on plain paper first and hold it against your sheet, up to the light, to check the fit.
The ready-cut layouts come from the sheet makers' published templates (Label Planet for A4, OnlineLabels for US Letter). Other brands' sheets with the same number and size of labels are usually laid out the same way.
What differs from a candle label (EU and UK)
A reed diffuser is fragrance dissolved in a solvent, and a room spray is fragrance in alcohol or water, so the liquid is classified more often and more heavily than a candle. The classes that most often apply:
- Flammability, set by the liquid's flash point: an alcohol-based room spray is commonly category 2 (H225, "Danger"); a diffuser base can be category 3 (H226) or outside the class, depending on the solvent.
- Aspiration hazard: a thin hydrocarbon diffuser base is the typical case, with the GHS08 pictogram, "Danger" and H304, "May be fatal if swallowed and enters airways".
- Eye irritation and skin sensitisation (H319, H317), from the higher fragrance load.
Two of these reach past the label to the bottle. Under Article 35(2) of CLP and Annex II Part 3, a product sold to the public needs a child-resistant closure (EN ISO 8317 for reclosable packs) when it is classified for aspiration hazard, acute toxicity category 1 to 3, skin corrosion, or single- or repeated-exposure organ toxicity category 1, or holds 3 % or more methanol or 1 % or more dichloromethane; and a tactile warning of danger (EN ISO 11683) when it is classified for aspiration hazard, a category 1 or 2 flammable liquid, acute toxicity, skin corrosion, respiratory sensitisation or organ toxicity, among others, whatever the size of the bottle. The tool names the ones your classification asks for under "Check before printing". Aerosols and sealed sprays have narrow exceptions. These are features of the bottle and cap, so settle them before you design the label. The same rules apply in Great Britain.
Pump and trigger sprays are liquids, and this tool covers them. Pressurised aerosol cans (H222, H223, H229) are not in its table. The full answer, with sources: reed diffuser and room spray labels.
In the United States
A US reed diffuser or room spray carries no CLP pictograms. Its warning comes from the Federal Hazardous Substances Act when the finished liquid is flammable or combustible, toxic, an irritant or a strong sensitizer (15 U.S.C. 1261(f) and (p); 16 CFR Part 1500):
- The flash point decides the words: at or below 20 °F it is EXTREMELY FLAMMABLE, with DANGER; below 100 °F, FLAMMABLE; up to 150 °F, COMBUSTIBLE (16 CFR 1500.3(c)(6)).
- Listed substances bring their own words: 10 % or more petroleum distillates means DANGER, "Harmful or fatal if swallowed" and "Call physician immediately"; 4 % or more methanol adds POISON and the skull and crossbones (16 CFR 1500.14). With 2 % or more oil of bergamot the product is a strong sensitizer (16 CFR 1500.13).
- The warning block: the signal word and the statements of hazard in capitals, boxed on the front, at least as tall as Table I of 16 CFR 1500.121 sets for your bottle, then the components that cause the hazard, precautions, first aid, "Keep out of the reach of children" and your name and place of business.
- Child-resistant packaging for a hazardous liquid with 10 % or more hydrocarbons and a viscosity under 100 SUS at 100 °F, unless the only way in is a locked or child-resistant spray (16 CFR 1700.14(a)(31)), and for liquids with more than 5 % methyl salicylate, 10 % turpentine, 4 % methanol or 10 % ethylene glycol.
- Every pack, hazardous or not: what it is, on the front; the net contents in fluid ounces and millilitres, in the bottom 30 % of the front; and your name and place of business (16 CFR Part 500).
CPSC staff will comment informally on a draft label if you send them the label, the full formula and your hazard data (16 CFR 1500.128). California's Proposition 65 warnings do not apply to a business with fewer than 10 employees (Health and Safety Code 25249.11(b)).
The rules in full: US reed diffuser and room spray labels, and four labels made with this tool in the US examples.
