CPSC Candle Regulations for the US Market

Scented candles represent one of the fastest-growing segments in the home fragrance market, and the United States is the largest single-country market. For B2B suppliers, importers, and private-label brands, compliance with the Consumer Product Safety Commission (CPSC) requirements and associated ASTM standards is mandatory for legal sale. This article covers the regulatory landscape in practical detail.

Regulatory Authority and Scope

The CPSC regulates candles as consumer products under the Consumer Product Safety Act (CPSA) and the Federal Hazardous Substances Act (FHSA). Unlike cosmetics, candles are not regulated by the FDA. The CPSC’s authority covers:

• Fire safety performance standards
• Labeling and warning requirements
• Banned substances (lead wicks)
• Recall authority for defective products

The CPSC does not pre-approve candles before sale. Compliance is the responsibility of the manufacturer or importer, and enforcement occurs through market surveillance, complaint investigation, and import screening at ports of entry.

ASTM F2417: Fire Safety Standard for Candles

ASTM F2417, “Standard Specification for Fire Safety for Candles,” is the primary performance standard referenced by the CPSC. While technically voluntary, the CPSC has indicated that non-compliance may be treated as evidence of a substantial product hazard under Section 15 of the CPSA.

Key requirements of ASTM F2417:

Flame height: The maximum flame height must not exceed 3 inches (76 mm) measured from the top of the wick to the tip of the flame under still-air conditions. Testing is conducted after the candle has burned for a minimum of 1 hour.

Secondary ignition: The candle must not cause secondary ignition of the container, decorative elements, or packaging during normal use. This is tested by burning the candle to its full burn time in a controlled environment.

Stability: Candles must remain stable on a 10-degree inclined surface without tipping. Container candles must not crack, shatter, or leak molten wax during normal burn.

Container integrity: Glass containers must withstand thermal stress without failure. The standard references ASTM F2601 for glass container testing, which includes thermal shock testing (minimum 100 degrees C differential).

Burn rate: While not strictly limited, candles with abnormally high burn rates that create unsafe pool depths may be deemed non-compliant with the general fire safety intent.

Testing protocol essentials:

• Test a minimum of 3 units per SKU
• Condition samples at 23 +/- 2 degrees C and 50 +/- 5% RH for 24 hours before testing
• Conduct tests in a draft-free environment (air velocity below 0.1 m/s)
• Document flame height at 15-minute intervals throughout the burn
• Retain test records for minimum 3 years (recommended: 5 years)

Labeling Requirements

Candle labeling in the US is governed by the Fair Packaging and Labeling Act (FPLA) and CPSC regulations under 16 CFR Part 1500.

Mandatory label elements:

1. Product identity: “Scented Candle,” “Pillar Candle,” “Container Candle,” etc.
2. Net quantity: In both metric and US customary units (e.g., “Net Wt. 8 oz / 227 g”)
3. Manufacturer/distributor name and address: Full legal entity and city/state/ZIP
4. Country of origin: “Made in China,” “Product of Vietnam,” etc. (per 19 CFR 134)
5. Warning labels: Per ASTM F2417 Section 7 and the FHSA

Required warnings (ASTM F2417):

The standard specifies a safety warning that must appear on the label or accompanying instructions:

• “BURN WITHIN SIGHT”
• “KEEP AWAY FROM THINGS THAT CATCH FIRE”
• “KEEP AWAY FROM DRAFTS, CHILDREN AND PETS”
• “NEVER LEAVE A BURNING CANDLE UNATTENDED”

The warning must use signal word “WARNING” in uppercase, with specific type size requirements relative to the label area. Pictograms (the ASTM candle safety icons) are strongly recommended and increasingly expected by retailers.

Additional labeling for scented candles:

• Fragrance description (e.g., “Lavender & Vanilla”)
• Burn time estimate (e.g., “Approximate burn time: 45 hours”)
• Wax type if making material claims (e.g., “100% Soy Wax”)

The Lead Wick Ban

Since October 2003, the CPSC has banned candles with lead-core wicks under 16 CFR 1500.861. The rule defines a lead-containing wick as one with more than 0.06% lead by weight in the wick or wick tab.

Compliance requirements:

• All wicks must be tested for lead content (XRF screening followed by acid digestion and ICP-MS for confirmation)
• The 0.06% threshold applies to the entire wick assembly, including the metal sustainer tab
• Importers must maintain test records demonstrating compliance
• The CPSC has conducted targeted import surveillance, with seizures of non-compliant products at ports

For B2B suppliers: request lead-free wick certificates from your wick supplier and conduct incoming inspection testing on a statistical sampling basis (AQL 2.5 is common practice).

California Proposition 65

California’s Safe Drinking Water and Toxic Enforcement Act (Prop 65) adds requirements beyond federal law:

• Lead and cadmium: If candle components (glass, ceramic containers, metallic decorations) contain lead or cadmium above safe harbor levels, a Prop 65 warning is required.
• Combustion byproducts: Burning candles can generate trace amounts of listed chemicals. While the CPSC has not required Prop 65 warnings for normal combustion, some plaintiffs’ attorneys have targeted candle brands.
• Fragrance ingredients: Certain phthalates used as fixatives (DEHP, DINP) are Prop 65 listed. If present above 0.1% in the finished product, a warning may be required.

Practical approach: Many brands include a general Prop 65 warning on all products sold in California to avoid litigation risk. The warning format is specified in 27 CCR 25603.

State and Local Requirements

Beyond California:

• New York: Requires general product safety compliance and may enforce through the Department of State.
• Massachusetts: Has adopted ASTM F2417 by reference in fire safety regulations.
• Various municipalities: May have additional fire code requirements for candle sales in certain venues.

Retailer-Specific Requirements

Major US retailers impose requirements beyond CPSC minimums:

• Walmart: Requires third-party testing to ASTM F2417, ASTM F2601 (glass), and lead-free wick verification. Testing must be conducted by a CPSC-accepted laboratory.
• Target: Requires compliance with their internal candle safety specification, which includes additional burn testing parameters.
• Amazon: Requires ASTM F2417 test reports for candle listings and may request documentation during product review.

Practical Compliance Checklist

1. Test all SKUs to ASTM F2417 (flame height, stability, secondary ignition)
2. Test glass containers to ASTM F2601 (thermal shock)
3. Verify wicks are lead-free (below 0.06% lead by weight)
4. Apply FPLA-compliant labeling with net quantity, origin, and manufacturer info
5. Include ASTM F2417 safety warnings with correct signal word and formatting
6. Screen for Prop 65 listed substances in all components
7. Retain all test reports and maintain a product compliance file per SKU
8. Use only CPSC-accepted laboratories for testing where retailer requirements apply
