Candle Label Requirements: CPSC, ASTM, and GHS Explained for Small Makers

Candle labeling is more regulated than most small makers realize. It's not just about putting your brand name on a pretty jar. You've got the Consumer Product Safety Commission (CPSC), ASTM International standards, and potentially GHS (Globally Harmonized System) hazard communication all in play.

Get these right and you're protected legally. Get them wrong and you're exposed to product liability — or worse, recalled products.

Here's what actually needs to go on your candle labels.

The Three Regulatory Frameworks

1. CPSC — Consumer Product Safety Commission

The CPSC oversees product safety in the US and has jurisdiction over candles as consumer products. If your candle causes injury and you didn't include appropriate warnings, you're exposed to liability.

2. ASTM F2601 — Standard Safety Label Requirements

ASTM International published ASTM F2601, the voluntary consensus standard for candle safety labeling. While voluntary at the federal level, following it is the industry standard and provides significant legal protection. Many retailers require ASTM F2601 compliance.

3. GHS — Globally Harmonized System

If your candle contains fragrance oils or other chemical components that meet hazard classification thresholds, you may need GHS hazard labeling. This applies more often to candle businesses selling to wholesale accounts or professional buyers.

What ASTM F2601 Requires

The ASTM F2601 standard specifies the following safety warnings for candles:

Required Warning Label Text (exact wording matters):

Your candle must include a label with warnings along these lines — ASTM provides the approved text:

• Burn within sight — Never leave a burning candle unattended
• Keep away from things that can catch fire
• Keep away from children and pets
• Burn on a heat-resistant surface
• Keep candle free of debris
• Stop use when 1/2 inch of wax remains
• Trim wick to 1/4 inch before lighting

ASTM F2601 specifies the exact warning statements and requires that they be readable. Most candle makers use a pre-approved "warning label" that contains all required elements in a compact format.

Label Placement

The warning label should be on the bottom of the candle or on the side where it's clearly visible. It must remain legible in normal use.

Your Brand Label Requirements

Beyond safety warnings, your candle label should include:

• Product name (what kind of candle it is, the scent name)
• Net weight — in both ounces and grams
• Your business name and address (or website)
• Fragrance/ingredients disclosure — especially if making any claims about "natural" or "clean" ingredients
• Burn time — not legally required but expected by consumers and often required by retailers

Fragrance Allergen Disclosure

The International Fragrance Association (IFRA) publishes guidelines for fragrance allergen labeling. While not legally mandated in the US (unlike in the EU, where 26 fragrance allergens must be listed above certain concentrations), following IFRA guidance is good practice and may be required by wholesale buyers and retailers.

If you're selling into any European markets, fragrance allergen disclosure becomes mandatory — worth knowing if you ever plan to export.

GHS Labeling: When Does It Apply to Candles?

GHS hazard labeling is primarily required for:

• Occupational/industrial products sold to businesses
• Products that qualify as hazardous materials under specific chemical thresholds

For retail candles sold directly to consumers, GHS labeling isn't typically required under US law. However:

• Some fragrance concentrates and candle-making supplies may require GHS labels
• If you're selling to wholesale buyers or institutions, they may require SDS (Safety Data Sheets) for your products
• Candles with very high fragrance loads might technically qualify as flammable

When in doubt, consult with a product safety attorney or contact CPSC directly.

The Standard Candle Warning Label

The National Candle Association (NCA) offers approved warning label artwork that meets ASTM F2601. Using their approved format is the easiest way to ensure compliance. You can find it at candles.org.

Most candle label suppliers also offer warning label options you can add to your label design.

Practical Label Design Tips

For jar candles:

• Front label: brand name, scent name, burn time
• Bottom label: ASTM safety warnings, net weight, business address

For tin candles:

• Side label or wrap: brand, scent, warnings — everything fits together
• Bottom label is another option for overflow content

For pillar candles:

• Wrap-around band or hang tag
• Include all required warnings — they need to be on the product, not just on outer packaging

Applying Labels to Candles

Candle jars and tins are actually great for semi-automatic labeling because they're round and consistent. A wrap-around labeler can apply your labels precisely and quickly.

The challenge: candles are often sold in cases where the label needs to look perfect at retail. Crooked or bubbled labels stick out on a retail shelf. If you're scaling into wholesale or boutique retail, consistent label application matters.

The Zap Labeler works well for jar candles — standard round containers with consistent diameters. At 30+ labels per minute, a 200-candle batch takes less than 10 minutes to label vs. 45+ minutes by hand.

Summary

Candle labeling compliance comes down to three things:

1. ASTM F2601 safety warnings — include all required warning statements
2. Standard product info — name, weight, your business info
3. Fragrance disclosure — know what's in your fragrance oil and disclose appropriately

If you're selling through retailers or online marketplaces, expect them to ask for proof of compliance. Having your ASTM warning label in place from day one keeps you ahead of that conversation.
