Candles are a popular product, but are they dangerous cargo? When transporting goods, it is important to understand what is considered dangerous by international law. Dangerous goods are typically items that pose a high risk of damaging people, property, or the environment. While candles are not explicitly listed as dangerous goods, they are flammable and may contain additives that make them hazardous. This means that they could be classified as a dangerous good and require special care during transportation. Additionally, candles must comply with various regulations, safety standards, and labelling requirements, especially when travelling by plane.

Flammability
Candles are not classified as hazardous materials, but they are considered dangerous goods due to their flammability. When shipping, the shipper must appropriately categorise, package, mark, and label the item to indicate the hazard before handing it to a carrier.
The exact chemical composition of a candle will determine its level of hazard. Candles made purely from wax are not considered hazardous materials. However, most candles contain fragrances, colours, or gels that can make them fall into the hazardous materials category. The safety level of a fragrance does not depend on whether it is natural or synthetic. Instead, it depends on the concentration of the specific VOC in the air. Fragrance formulas are reviewed against the safety standards established by the International Fragrance Association (IFRA). Each ingredient in the fragrance and the finished product must meet the specifications set by the IFRA to be compliant with the standard. If the fragrance and product meet the standard, the fragrance VOCs are considered safe for human use.
The federal government, along with California and several other states, have established VOC regulations for consumer products such as candles and air fresheners. They limit the concentration of VOCs in these and many other consumer products. Additionally, the minuscule amount of soot produced by a candle is the natural byproduct of incomplete combustion. Candle soot is composed primarily of elemental carbon particles, similar to the soot from kitchen toasters and cooking oils. These everyday household sources of soot are not considered a health concern and are chemically different from the soot formed by burning diesel fuel, coal, or gasoline.
However, it is important to note that any item that combusts releases carcinogens. Candles can release toxic chemicals into the air, especially if they contain essential oils or additives for fragrance and colour at high concentrations. The oils found in certain fragrances may slightly increase the small amount of soot produced by a candle. However, wick length and flame disturbance are the primary factors that impact sooting in a properly formulated candle. Burning candles is not the healthiest choice, but it is similar to having a campfire or a gas oven, plastics in your home, eating meat, or going into the sun.
Overall, while candles are not classified as hazardous materials, their flammability and potential to release toxic chemicals when burned make them a dangerous good.

Toxic chemicals
While candles are not classified as hazardous materials, they are often considered dangerous goods due to their flammability. The danger also depends on the candle's chemical composition. For instance, candles with fragrance, colour, or gel are more likely to be hazardous.
Candles can release toxic chemicals into the air, even when they are not lit. The type and amount of toxic chemicals released depend on the type of candle.
Paraffin Wax Candles
Paraffin wax candles are made from petroleum waste that has been chemically bleached and deodorized. When burned, these candles can release toxic volatile organic compounds (VOCs) into the air, including known carcinogens like benzene. They also produce soot composed of particulate matter such as PM2.5 and ultrafine particles that can remain suspended in the air for hours and penetrate deeply into the lungs.
Synthetic Fragrances and Dyes
Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature. Exposure to VOCs can cause headaches, irritation to the eyes, nose, or throat, nausea, and even damage to the liver, kidneys, or central nervous system.
Lead-Core Wicks
Candles with lead-core wicks release five times the amount of lead considered hazardous for children and exceed EPA pollution standards for outdoor air. Lead has been linked to hormone disruption, behavioural problems, learning disabilities, and numerous health problems. Although lead wicks were banned by the US Consumer Product Safety Commission in 2003, some imported candles may still contain lead.
Allergies and Asthma
The chemicals released by scented candles can also trigger allergic reactions and asthma attacks in susceptible individuals.
Non-Toxic Alternatives
To avoid exposure to toxic chemicals, consumers can choose candles made from natural sources, such as beeswax, soy wax, or other plant-based waxes. These candles produce less soot and toxic chemicals than paraffin wax candles and are a healthier option for indoor use.

Negative health effects
While candles are not classified as hazardous materials, they are considered dangerous goods due to their flammability. In addition, candles, particularly scented candles, may have negative health effects.
Firstly, candles release small amounts of toxic chemicals into the air when they combust. These chemicals are carcinogenic and can be harmful to health, especially in large doses. The specific chemicals released depend on the candle's composition, including the type of wax and the presence of fragrances, colours, or gels. For example, paraffin wax candles have been associated with the release of harmful chemicals, while plant-based oils may emit fewer toxins.
Secondly, the fragrances in scented candles can trigger negative reactions in individuals with sensitivities. These reactions may be due to the specific ingredients used in the fragrances, which can increase the amount of soot produced by the candle. Soot is a natural byproduct of incomplete combustion and, while typically considered harmless in small amounts, it can be minimised by trimming the wick, avoiding drafty areas, and keeping the wax pool free of debris.
Thirdly, the presence of lead wicks in candles can pose a health risk. Lead wicks have been banned in the United States since 2003, but they were previously found in inexpensive imported candles.
Finally, candles can pose an indirect health risk by increasing the risk of fires, particularly when left unattended. This risk is heightened when candles are placed in drafty areas, where the flickering flame can come into contact with nearby objects.
Overall, while candles may have negative health effects, these risks can be mitigated by taking proper precautions, such as burning candles in well-ventilated areas, using candles with safe ingredients, and following fire safety guidelines.

Proper storage
Candles are not classified as hazardous materials, but they are considered dangerous goods due to their flammability. The exact chemical composition of a candle determines whether it is classified as a hazardous material. Fragrances, colours, or gels in candles can cause them to be classified as hazardous materials.
If you are storing candles, it is important to keep them in a cool, dry place, away from direct sunlight or heat sources. This will prevent the wax from melting or softening, which can affect the candle's performance and appearance. It is also important to keep the storage area well-ventilated to prevent the build-up of any fumes or odours from the candles.
Additionally, it is crucial to store candles away from any open flames or other sources of ignition. This includes keeping them away from heaters, stoves, or other appliances that may produce sparks or flames. Candles should also be stored out of the reach of children and pets to prevent accidental ingestion or injury.
To maintain the quality of the candles, it is recommended to store them in their original packaging or in a sealed container. This will protect them from dust, debris, and other contaminants that can affect their performance and appearance. It is also important to handle candles with care during storage, avoiding any damage to the wax or wick that could impact their burning performance.

Transportation
The transportation of candles is a complex issue that requires careful consideration of safety regulations and guidelines. While candles made purely of wax are typically not classified as hazardous materials (Hazmat), they are often considered dangerous goods due to their flammability. This classification has significant implications for packaging, labelling, and shipping procedures.
When transporting candles, it is crucial to adhere to the relevant regulations and requirements. In the United States, the Department of Transportation's Hazardous Materials Regulations (HMR) outline specific guidelines for classifying, packaging, marking, and labelling dangerous goods. Candles, due to their flammability, would fall under Class 4, which includes flammable solids. This classification determines the necessary precautions and procedures for safe transportation.
To ensure compliance, shippers must appropriately categorize, package, mark, and label candles as dangerous goods before handing them over to a carrier for shipping. This involves following specific packaging guidelines, such as using suitable materials and including proper labelling that indicates the nature of the cargo. Additionally, certain modes of transportation, such as sea freight, air freight, and road transport, may have additional regulations and requirements for transporting dangerous goods like candles.
It is worth noting that the composition of candles can vary, and some may contain fragrances, colours, or gels that could impact their classification. These additives can introduce hazardous chemicals, potentially pushing candles into the hazardous materials category. Therefore, it is essential to refer to the Safety Data Sheet (SDS) of the specific candle product to determine its exact chemical composition and any associated hazards. The SDS provides crucial information on hazards identification, firefighting measures, transportation guidelines, and regulatory information.
Furthermore, the transportation of candles may be subject to state-specific laws and regulations. For example, certain states in the US have established Volatile Organic Compound (VOC) regulations for consumer products like candles, limiting the concentration of VOCs to ensure safety. These regulations must be considered when transporting candles to comply with local requirements.
