Candles are a popular product to sell and ship, but are they hazardous? The short answer is: it depends. While wax candles are not considered hazardous, most candles contain fragrance, colour, or gel, which can make them fall into the hazardous materials category. The Federal Hazardous Substances Act (FHSA) lists candles made with metal-cored wicks as potentially dangerous, and California Proposition 65 restricts certain chemicals commonly found in candles, such as benzene, due to health risks. Shipping companies like USPS classify hazardous materials as items that are dangerous or injurious to life, health, or property, and impose penalties for non-compliance. Candle sellers must be aware of regulations and safety standards to ensure their products are shipped safely and legally.

What You'll Learn
Flammability
Candles are not typically classified as hazardous materials (hazmat) if they are made of wax. However, they are often considered dangerous goods due to their flammability. The Federal Hazardous Substances Act (FHSA) lists candles with metal-cored wicks as potentially banned items due to the risk of lead content. These candles are only permitted if the lead content does not exceed 0.06% of the total weight of the metal core.
The exact chemical composition of candles, including fragrances, colours, or gels, can impact their flammability and hazardous classification. It is important to refer to the Safety Data Sheet (SDS) for detailed information on hazards, firefighting measures, transportation, and regulatory requirements.
When shipping flammable items, specific guidelines and restrictions must be followed to ensure safety and compliance. These guidelines include proper packaging, labelling, and transportation methods. Failure to adhere to these guidelines can result in civil and criminal penalties, as well as cleanup and damage costs.
To comply with shipping regulations, it is essential to understand the flashpoint and toxicity of the items being shipped. Flammable substances, such as certain glues, may be shipped if they meet the criteria of a consumer commodity and are transported via ground transportation. However, items like matches, propane, and butane fall under hazardous materials and have specific restrictions.
Additionally, hand sanitizers, including wipes, are considered hazardous materials due to their flammable nature and must be shipped using specific services, such as USPS Ground Advantage or Parcel Select, with surface transportation-only restrictions in domestic mail.

Toxic substances
While candles are not classified as hazardous materials (if made out of wax), they are often labelled as 'Dangerous Goods' due to their flammability. Most candles are made from paraffin wax, a petroleum product that contains benzene. Benzene is restricted by California Proposition 65 due to its risks of causing damage to an infant's brain development and the male reproductive system. Exposure to excess benzene can also cause leukaemia.
Burning candles releases hydrocarbons and volatile organic compounds (VOCs) into the air, which can be harmful in large quantities. A study found that burning scented candles indoors resulted in higher quantities of pollutants such as formaldehyde, CO2, and VOCs than background levels, indicating that the candles were a source of indoor pollution.
Additionally, scented candles can contain dyes and artificial scents that release a variety of chemicals when burned. These chemicals can include formaldehyde, toluene, benzopyrene, and benzene derivatives, which have been linked to various health issues. For example, a 66-year-old woman was diagnosed with exogenous lipoid pneumonia after inhaling vaporized paraffin from burning candles.
Furthermore, candle wicks containing lead have been banned in the United States since 2003 due to concerns about lead poisoning, especially in children. However, candles with metal-cored wicks are still available as long as the lead content does not exceed 0.06% of the total weight of the metal core.
The use of scented candles has also been linked to allergic reactions and asthma attacks, with many people experiencing symptoms such as headaches, shortness of breath, and coughing. To minimise the potential risks associated with burning candles, it is recommended to choose high-quality candles made from natural materials like beeswax or soy wax and to ensure proper ventilation when burning candles indoors.

Shipping restrictions
When shipping candles, it is important to be aware of any restrictions that may apply. While candles are not typically classified as hazardous materials (if made out of wax), they may be considered dangerous goods due to their flammability, especially when they contain essential oils, fragrances, colours, or gels. Therefore, it is crucial to refer to the Safety Data Sheet (SDS) of the candles, specifically Sections 2, Hazard(s) Identification, 5 Firefighting Measures, 14 Transportation, and 15 Regulatory Information.
In the United States, the Federal Hazardous Substances Act (FHSA) imposes restrictions on candles with metal-cored wicks. These candles are considered dangerous due to the potential presence of lead, which can be harmful if the lead content exceeds the maximum allowable limit. To comply with FHSA regulations, manufacturers and importers must ensure that the lead content in the metal core does not exceed 0.06% of the total weight. Additionally, FHSA requires that these candles be shipped in an outer container or wrapper with a specific warning label.
California Proposition 65 also restricts certain chemical substances that may be found in candles, such as benzene, which is a component of paraffin wax. If importers cannot prove compliance with Proposition 65, they must label their candles with safety warnings to inform consumers about potential hazards or toxic substances.
When shipping candles through postal services like USPS, it is important to adhere to their guidelines and restrictions. USPS prohibits the mailing of hazardous materials that pose a danger to life, health, or property. Violations can result in civil and criminal penalties. While candles are not specifically mentioned, it is important to refer to their hazardous materials guidelines and consult the manufacturer if unsure. Additionally, USPS provides specific guidelines for shipping cremated remains, handguns, and flammable items like glues.
Overall, when shipping candles, it is essential to be aware of the specific regulations and restrictions that may apply based on the candle's composition and the shipping destination. Proper labelling, compliance with safety standards, and adherence to postal service guidelines are crucial to ensure safe and legal transportation.

Regulatory requirements
The regulatory requirements for shipping candles are dependent on the chemical composition of the candles. In the United States, the Federal Hazardous Substances Act (FHSA) stipulates that candles with metal-cored wicks or candle wicks are considered hazardous products. These candles are banned from the US market unless they do not exceed the maximum allowable lead limit of 0.06% of the total weight of the metal core. To be sold in the US, these candles must be shipped in an outer container or wrapper with a label stating the lead content.
The FHSA also requires importers and manufacturers of certain candles to issue a General Certificate of Conformity (GCC) to demonstrate compliance with safety standards. This certificate is necessary for candles that fall under the scope of 16 CFR Part 1500.17.
Additionally, California Proposition 65 restricts the sale of candles containing certain toxic chemical substances, such as benzene, which is commonly found in paraffin wax and can cause harm to infant brain development, the male reproductive system, and can cause leukemia. If importers cannot prove compliance with this proposition, they must label their candles with safety warnings to inform customers of potential hazards.
When shipping candles, it is important to follow the guidelines of the shipping carrier, such as USPS, which has specific restrictions on hazardous materials. These materials are prohibited or restricted and can result in civil and criminal penalties if they are mailed. Flammable materials, for example, are restricted to surface transportation within the domestic mail system and are prohibited from international mail.
Furthermore, the ASTM standards provide guidelines for candle regulations, lab testing, and labelling requirements in the United States. These standards aim to improve safety and reduce fires, injuries, and deaths associated with candle usage.
Overall, it is essential to refer to the specific regulatory requirements of the region and shipping carrier when shipping candles to ensure compliance with hazardous material regulations.
