Candle Label Requirements in the USA: ASTM and CPSC Compliance

Candle labeling in the United States is governed by a combination of federal law, voluntary standards adopted by regulators, and state-level rules. A non-compliant label can trigger a CPSC recall, a customs hold, or a retailer rejection, all of which cost far more than getting the artwork right the first time. This guide explains exactly what must appear on a US candle label and where.

The Regulatory Framework

Candles are classified as household products under the Federal Hazardous Substances Act (FHSA), administered by the Consumer Product Safety Commission (CPSC). The CPSC has formally incorporated ASTM F2417, the Standard Specification for Fire Safety Labeling of Candles, into its enforcement guidance. ASTM F2058 covers measurement and test methods, while ASTM F2417 dictates the label content itself.

Although ASTM standards are technically voluntary, the CPSC treats them as the benchmark for “reasonable safety.” Retailers including Walmart, Target, and Amazon require ASTM F2417 compliance as a condition of sale, so for any commercial candle brand the standard is effectively mandatory.

Mandatory Label Elements

Every retail candle sold in the US must display the following:

1. Manufacturer or Importer Identity

Print the legal name and full street address (city, state, ZIP) of the US manufacturer or importer. A PO box alone is not sufficient. If the candle is imported, the label must also state the country of origin, for example “Made in China” or “Product of China,” in a conspicuous location.

2. Net Quantity of Contents

State the net weight of the wax in both avoirdupois (ounces/pounds) and metric (grams/kilograms) units, per the Fair Packaging and Labeling Act (FPLA) enforced by the FTC. Volume is not required for candles, but if you list it, it must be accurate.

Example: “Net Wt. 8 oz (227 g).“

3. Common Product Identity

A clear statement of what the product is, such as “Scented Container Candle” or “Pillar Candle.”

4. ASTM F2417 Fire Safety Warning

This is the most regulated element. The label must include:

• The safety alert symbol (an exclamation point inside an equilateral triangle).
• The signal word “WARNING” in uppercase, bold, and at least 1/8 inch tall for small packages.
• A hazard statement: “Fire or burn hazard.”
• Specific precautionary statements, including:
  • “Burn within sight. Keep away from things that catch fire.”
  • “Keep away from drafts, children, and pets.”
  • “Trim wick to 1/4 inch before lighting.”
  • “Keep wax pool free of debris.”
  • “Discontinue use when 1/2 inch of wax remains” (for container candles).
• The manufacturer’s contact for safety information.

The CPSC requires the warning to be in English and to occupy at least 4 percent of the principal display panel area or appear on an information panel directly adjacent.

5. Burn Time and Burn Instructions (Recommended)

While not strictly mandated, including estimated burn time and step-by-step burn instructions is treated as best practice and is required by most major retailers.

Typography and Placement Rules

• The signal word “WARNING” must contrast with surrounding text and be in a font at least twice the size of body copy.
• All required text must be in English. Bilingual labels are permitted, but English must be present and predominant.
• The label must be affixed to the bottom or side of the candle vessel for container candles, and to the wrapper or hang tag for pillar and taper candles.
• For multi-pack sets, the outer carton must carry the warning even if individual units do.

State and Retailer Add-Ons

• California Proposition 65: If the candle contains any listed chemical above the safe-harbor threshold (for example, certain phthalates in fragrance or lead in wicks, which are banned anyway), a Prop 65 warning is required for sales into California.
• Massachusetts and New York have additional flammable product packaging rules that some retailers extend nationwide.
• Amazon requires a downloadable SDS, a UPC, and photos of the actual label showing the ASTM warning before listing approval.

Cost of Compliance

For a brand working with a Chinese OEM such as Aromiso, label compliance is essentially a design and proofing cost:

• Label artwork revision: USD 50 to USD 200 per SKU
• ASTM F2417 burn testing through an accredited lab (Intertek, SGS, UL): USD 800 to USD 2,500 per candle construction
• Prop 65 chemical screening: USD 500 to USD 1,500 per formulation

These costs are one-time per SKU and protect the brand from recalls that average USD 1 million in direct expense according to CPSC and insurance industry data.

Common Mistakes to Avoid

1. Using only a generic “burn safely” statement instead of the prescribed ASTM wording.
2. Omitting the country of origin on imported candles.
3. Printing the warning smaller than 1/8 inch signal-word height.
4. Placing the warning under the candle where it is hidden by packaging.
5. Listing net weight in metric only.
6. Failing to update labels when fragrance formulations change.

Working with Your Manufacturer

A competent OEM will provide a CPSC-ready label template, an SDS, and ASTM F2417 test data as part of the production package. At Aromiso, label artwork is reviewed against ASTM F2417 and FPLA requirements before printing, and burn-test reports are issued for each candle construction. Buyers should request these documents at the sampling stage so that label proofs and test results align before bulk production begins.

Final Thoughts

US candle labeling is not complicated, but it is precise. Build the ASTM F2417 warning, the FPLA net quantity statement, the country of origin, and the importer identity into your label template from day one, and verify with an accredited lab before your first container ships. Brands that treat labeling as a compliance checkbox rather than a design constraint avoid the most expensive mistakes in the candle business.
