Labeling Essential Oil Candles in the US: What Is Required

The fire-safety warning most candle makers put on a label is not the part of candle labeling that federal law spells out. The mandatory items we could verify from primary pages are narrower and more mundane: what the product is, who made it, how much is in it, a lead limit for metal-cored wicks, and the rules against unsupported claims. This post sorts what the pages we read call mandatory from what they call voluntary. It is a reading of public sources, not legal advice, and we sell mugwort oil, not candles or labels.

Mandatory 1: identity, maker, net quantity

The FTC says the Fair Packaging and Labeling Act covers "all consumer commodities other than food, drugs, therapeutic devices, and cosmetics" and requires the net contents, the identity of the commodity, and the name and place of business of the manufacturer, packer or distributor (FTC, Fair Packaging and Labeling Act). The regulation on the name and place of business requires the label to "specify conspicuously" them (16 CFR 500.5). The net-quantity rule requires a declaration as a distinct item on the principal display panel in the bottom 30 percent of it, without qualifying words like "jumbo", with an exception from the location rule for panels of 5 square inches or less (16 CFR 500.6). We did not read the definition of "consumer commodity" in 16 CFR 500.2, which is why the candle placement is marked as inference, and the exact unit and format rules are in the regulation text, not in this summary.

Mandatory 2: lead in wicks, and a citation correction

Candles made or imported on or after October 15, 2003 with metal-cored wicks must have a core with no more than 0.06% lead by weight, and bulk packaging carries the statement "Conforms to 16 CFR 1500.17(a)(13)"; retail packaging does not need it. CPSC requires a general certificate of compliance for metal-cored wick candles, and says candles with nonmetal wick cores have no certification requirement (CPSC, candles; 16 CFR 1500.17). Mind the paragraph number: in the text we read, (a)(11) of that section concerns fireworks, and the candle wick provision is (a)(13). The National Candle Association's own page says lead wicks have been banned in the United States since 2003 (NCA, 18 January 2019); the regulation is narrower, concerning metal-cored wicks above the stated limit, so quote the rule, not the slogan, if you print a lead-free claim.

Conditional: the hazardous-substance label

CPSC's page says "candles that contain a hazardous substance as defined under the FHSA must bear cautionary labeling" and points to its FHSA labeling guidance. The page does not say whether wax scented with an essential oil crosses that line, and it does not mention fragrance or essential oil at all. We cannot answer it either. The oil's safety data sheet is the starting document, and a product-safety attorney or an accredited testing laboratory is the person who decides whether your finished candle needs a cautionary label. We publish a COA but not a safety data sheet, and a buyer who needs one should request it in writing; US hazard communication rules require manufacturers and importers to provide a sheet to distributors and employers with the first shipment (29 CFR 1910.1200(g)(6)).

Voluntary, and still the norm: ASTM F2058

ASTM F2058, Standard Specification for Candle Fire Safety Labeling (version F2058-07(2021)), covers "requirements for fire safety information to be placed on candle units of sale". The abstract says the warning goes on the unit of sale and must be visible to the consumer at the point of sale; it must not be covered, obstructed or removed by the manufacturer, distributor or retailer; the text-only form is the safety alert symbol followed by "WARNING" in uppercase boldface; and a text-and-pictogram form uses the symbol followed by pictograms. Its scope ends with: "It is not the intent of this specification to address any other labeling requirements" (ASTM International, F2058-07(2021), abstract). The National Candle Association says every candle should carry a cautionary label with three rules, shown as symbols: burn within sight, keep away from combustibles, keep away from children and pets (NCA, 2019). CPSC lists F2058 with F2179 (glass candle containers), F2417 (fire safety for candles) and others as voluntary standards (CPSC).

What we have not read is the full standard: the abstract is public, the text is sold. The exact symbol artwork, type sizes and wording for each hazard are in the document you buy from ASTM, and state or retailer requirements that adopt it are for your attorney to check. Our recommendation, a position and not a legal conclusion, is to follow F2058 even though the sources call it voluntary: the NCA tells shoppers to avoid candles with no safety label, and the NFPA figures on candle fires, 20 a day in 2015 to 2019 according to the Illinois State Fire Marshal, are the reason the warning exists (Illinois OSFM, citing NFPA).

Claims: what a mugwort candle label cannot say

This is where an oil like mugwort draws trouble, because the oil's folk and ritual associations tempt copy such as "cleansing", "protective" or "for restful sleep". Three regulators are involved. FDA says the regulation of aromatherapy products "depends mainly on how they are intended to be used"; a fragrance marketed to help someone sleep or quit smoking is a drug, because intent is read from claims, advertising and consumer expectation (FDA, content current as of 11 September 2024). The same FDA aromatherapy page says some fragrance products, including air fresheners and scented candles, are regulated by the Consumer Product Safety Commission, and that advertising claims are regulated by the Federal Trade Commission (FDA, aromatherapy, content current as of 8 September 2023).

The FTC's health products guidance says health claims need "competent and reliable scientific evidence", generally randomized controlled human clinical testing, that implied claims count as much as express ones, and that the test is the consumer's understanding (FTC, Health Products Compliance Guidance). Its Green Guides explain which environmental claims may be deceptive but "do not address use of the terms 'sustainable,' 'natural,' and 'organic'," and are "not agency rules or regulations" (FTC, 1 October 2012). Read together, the plain approach is to describe what the object is: a scented candle, the wax, the scent name, the net weight, the burn instructions. Our shop copy makes no outcome claim for mugwort oil and neither should your label; for the plant's history, link to a source rather than print a promise.

California Proposition 65

California's Proposition 65 site says a company with fewer than 10 employees is exempt from the warning requirements, that such a business may still have contractual or indemnification obligations, and that others must give a "clear and reasonable" warning before knowingly and intentionally exposing anyone to a listed chemical, unless they can show the exposure is below the thresholds (California OEHHA, Proposition 65 warnings website, FAQ for businesses, undated). Whether anything in your wax, wick, dye or fragrance triggers it is a testing and legal question, and the supplier of each component is the first person to ask.

What the oil supplier can and cannot give a candle maker

We have not made or labeled a candle and have no test results to offer; every statement above is from the pages cited.

Sort your label by status before you design it: the items in the first two rows of the table are not optional, the warning is optional only on paper, and the open questions (hazard label, Proposition 65, state rules) go to a product-safety attorney and a testing laboratory.
