Big candle

For big candles, the choice of wax is critical to prevent cracking and ensure an even burn. Soy wax is preferred for eco-friendly branding and a cleaner burn, but it may require additives for structural stability in oversized formats. Paraffin wax offers the best scent throw and structural rigidity for pillar candles, while beeswax provides a longer burn time and natural honey scent. Always verify the melting point; higher melting point waxes (58°C-62°C) are essential for large candles to maintain their shape during shipping and display.

Large candles require multi-wick systems (2-5 wicks) to ensure a full melt pool and prevent 'tunneling.' Ensure wicks are made of lead-free cotton or FSC-certified wood. The fragrance load should be between 6% and 10%; exceeding this can compromise the wax structure and create a fire hazard. Additionally, check for UV inhibitors if the candles are white or light-colored to prevent yellowing under retail lighting.

Safety is paramount for large-format candles. Products must comply with ASTM F2417 (Standard Specification for Candle Fire Safety) in the US or EN 15493 in the EU. These standards cover flame height, stability, and secondary ignition. Furthermore, ensure the fragrance oils are IFRA (International Fragrance Association) compliant and that the product carries mandatory CLP labeling for the European market or CPSC cautionary labeling for the US.

For big candles in jars, the glass must be heat-strengthened or tempered to withstand prolonged thermal stress. Request thermal shock test reports from the supplier. Packaging for large candles must include high-density EPE foam or double-walled corrugated inserts to prevent breakage, as the high weight of the wax makes them susceptible to impact damage during cross-border transit.

The biggest risks are melting during transit and glass breakage. Avoid shipping during peak summer months or ensure the use of reefer containers (refrigerated) if traversing tropical routes. For fragile containers, insist on ISTA 3A drop-test standards for packaging.

Large candles often have higher material costs, so suppliers may be flexible on MOQ (Minimum Order Quantity) if you use standard scents but custom labels. Negotiate for tiered pricing where the unit cost drops by 15-20% at 1,000+ units. Request a pre-production sample and a burn lab report before releasing the 30% deposit to ensure the wick-to-wax ratio is optimized for the specific vessel size.

Be aware of anti-dumping duties on wax products which can vary significantly between regions (e.g., specific duties on Chinese candles in certain EU periods). Ensure the HS Code (typically 340600) is correctly declared. Provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) to your freight forwarder to avoid delays during customs clearance related to chemical safety checks.
