Wax melt and wax tart label requirements
Wax melts (also called wax tarts) are flameless — they melt in an electric or tea-light warmer instead of burning on a wick. That changes which warnings apply, but the packaging rules are largely the same as for candles.
How wax melts differ from candles
A wax melt has no open flame of its own. The hazard shifts from an exposed wick to the hot wax pool and the warmer's heat source. As a result:
- The classic ASTM F2058 "never leave a burning candle unattended" framing is adapted to the warmer: keep the warmer attended, on a stable heat-resistant surface, and away from children, pets, and anything that catches fire.
- Instructions point to the warmer manufacturer's directions rather than wick-trimming. ASTM F2417, Standard Specification for Fire Safety for Candle Accessories, covers the warmers and accessories themselves.
- You should still keep the core supervision and keep-away language — hot wax can scald, and an unattended warmer is a fire risk.
What stays the same: net weight and identity (FPLA)
Wax melts are consumer commodities, so the Fair Packaging and Labeling Act (15 U.S.C. §1453; 16 CFR Part 500) still applies. The package needs:
- A net-weight statement in dual units — US customary first, metric in parentheses — in the bottom 30% of the principal display panel, for example Net Wt 2.5 oz (71 g). Declare the wax only. How to format net weight →
- A manufacturer / distributor identity line with the business name and place of business.
Safety and warning language
Because a melt is flameless, its warning is warmer-focused. A typical wax-melt warning keeps the safety-alert symbol and signal word and adapts the precautionary statements:
Sources: ASTM F2058 / ASTM F2417 (candle and candle-accessory fire safety); FPLA, 15 U.S.C. §1453 and 16 CFR Part 500 (net weight and identity).
Prop 65 for wax melts
The same California rule applies: if a wax melt sold into California can expose consumers to a listed chemical above the safe-harbor level, include the short-form Proposition 65 warning (27 CCR §25603). California Prop 65 warning, explained →

Do wax melts need warning labels?
Yes. Even though wax melts are flameless, they carry burn-hazard and supervision warnings adapted to the warmer, plus the FPLA net-weight statement and identity line. ASTM F2417 covers the warmers themselves.
How do wax melt labels differ from candle labels?
A wax melt has no open flame, so its warning focuses on the warmer (use the correct warmer, never leave it unattended, hot wax can burn) rather than wick-trimming. The net-weight and identity rules are the same as for candles.
Do wax melts need a net-weight statement?
Yes. Under the FPLA, declare the net weight of the wax in dual units (US customary first, metric in parentheses) in the bottom 30% of the principal display panel.
Are wax tarts and wax melts the same thing?
Yes. "Wax tart" and "wax melt" are common names for the same flameless product that is melted in a warmer rather than burned on a wick. The labeling requirements are identical.
