If you source candles or scented candles from China to sell in the US or EU, this category has three completely independent risk lines — lead in the wick, glass container quality, and fragrance chemical composition. Many people only know “lead-cored wicks are banned,” but aren’t clear on exactly what that ban covers, or what other real risks in this category it doesn’t touch. This article covers all three lines, plus one particularly common misunderstanding worth clearing up.
1. The lead wick ban: real, but narrower in scope than many assume
The US CPSC banned lead-cored candlewicks back in 2003 under the Federal Hazardous Substances Act — per 16 CFR § 1500.17(a)(13), the metal core of a candlewick must not exceed 0.06% lead by weight, applying to all candles manufactured or imported after October 15, 2003. If metal-cored wicks are used, a General Certificate of Compliance (GCC) is required, explicitly citing “16 CFR § 1500.17(a)(13) – Metal-cored candlewicks”; bulk shipments must also carry a “Conforms to 16 CFR 1500.17(a)(13)” statement on the outer packaging. Non-metal-cored wicks (cotton, wood) carry no such certification requirement.
2. A key point many people get wrong: this bans lead, not “all metal-cored wicks”
This is the detail most worth paying attention to. Manufacturers originally used metal cores to solve the problem of pure cotton wicks curling or burning unevenly — after lead was banned, most switched to zinc-cored or tin-cored wicks to solve the same problem, and these alternatives remain legal and are extremely common today — a large share of metal-cored candles on the market today use zinc or tin, not lead. In other words, “metal-cored wick” itself is not banned — what’s banned is a metal core containing excess lead. The right question to ask a supplier is “exactly what metal is this wick core, and has it been tested for lead,” not simply “is it metal.”
Also worth noting: this ban has been in effect for more than 20 years, but enforcement on candles imported through unverified small third-party sellers is imperfect — CPSC has issued warnings as recently as within the past decade about imported candles testing positive for lead despite the ban’s long history. That means “the law banned it long ago” doesn’t guarantee “it’s already gone from the market” — you still need to actively verify, not assume the problem no longer exists.
3. An independent risk line: the glass container itself
The wick isn’t the only risk point in a candle. In 2024, DEMDACO’s “Maril” brand scented candles were recalled in the US — the glass containers could crack or break during burning, posing laceration and fire hazards, with about 3,000 units sold and 3 reports of glass breaking during use. This risk corresponds to the thermal-shock resistance and annealing quality of the glass container — Chinese third-party testing labs include “thermal differential and annealing testing for glass candle holders” as a standard candle test item, corresponding to the US’s ASTM F2179 standard (specifically covering annealed soda-lime-silicate glass produced for use as candle containers). If you’re sourcing glass-jar candles, this test is entirely separate from the wick’s lead testing, and both need to be verified independently.
4. Fragrance chemistry: governed by EU REACH, but candles aren’t “cosmetics”
There’s a scope point here that’s easy to get confused about. Candles are not classified as “cosmetics” under EU law, so the EU Cosmetics Regulation’s mandatory fragrance-allergen labeling requirements do not directly apply to candles (that rule governs true cosmetics like essential oils and perfumes, with new products required to meet an expanded allergen list from July 31, 2026).
But that doesn’t mean a candle’s chemical composition is unregulated — candles still fall under the EU’s REACH regulation, with testing scope potentially covering 200+ chemical substances, including chlorides and fluorides. Standard testing scope for fragrance/scented products at Chinese third-party labs typically includes: formaldehyde, benzene, toluene, xylene, total volatile organic compounds (TVOC), and soluble lead/cadmium/mercury/chromium/arsenic.
One more distinction worth keeping straight: IFRA (International Fragrance Association) standards are a voluntary industry self-regulatory framework, not government law — but because they’re widely adopted as a de facto industry standard, many fragrance suppliers will proactively offer an “IFRA Certificate.” It’s reasonable to require an IFRA certificate from your supplier, but understand it’s an industry-practice credential, not a legal mandate.
5. What to do before you order
- Ask explicitly what metal the wick core is made of. If it’s metal-cored, require a lead-content test report (against 16 CFR 1500.17(a)(13)) — don’t settle for a verbal “it’s not lead”; look at the actual test data.
- For glass-jar products, separately verify the annealing/thermal-shock test report for the glass container (against ASTM F2179) — this is an entirely different test from wick testing.
- Require a REACH test report for the fragrance composition if selling into the EU, checking compliance with limits on chlorides, fluorides, and related substances.
- Request an IFRA certificate as an industry-practice credential, but understand it’s not a legally mandated document.
- If selling in California, refer to our Prop 65 guide — candles are equally subject to this “right to know” law, and many sellers choose to simply apply the warning label rather than pay for testing; this doesn’t necessarily mean the product exceeds a limit, but it’s also a reminder not to assume “no warning label” automatically means “definitely safe.”
The bottom line
Compliance for candle products isn’t one line — it’s three independent ones: lead content in the wick (for metal cores), the thermal integrity of the glass container, and the chemical composition of the fragrance. “Metal core means banned” is a common but incorrect simplification — the real question is what metal, specifically, and whether it contains lead. Verifying all three lines separately protects you far better than accepting one general “compliance certificate” at face value.
