Wholesale candles

When selecting candles, the wax type is the most critical factor for quality and eco-friendliness. Soy wax and beeswax are preferred for their clean-burning properties and longer burn times compared to paraffin. Ensure the wick is lead-free, typically made of braided cotton or FSC-certified wood. For scented candles, verify that the fragrance oil concentration is between 5% and 10% to ensure a strong 'cold throw' and 'hot throw' without compromising the structural integrity of the wax.

Safety compliance is non-negotiable. For the US market, products must adhere to ASTM F2417 (Standard Specification for Candle Fire Safety) and CPSC labeling requirements. For the EU market, compliance with EN 15493 (Fire Safety), EN 15426 (Sooting Behavior), and REACH regulations for chemical substances is mandatory. Always request SDS (Safety Data Sheets) from the supplier to verify the chemical composition of dyes and fragrances.

Professional B2B buyers should prioritize suppliers with ISO 9001 certification and a monthly production capacity of at least 50,000 to 100,000 units to ensure scalability. For private labeling (OEM), confirm the supplier's ability to provide custom glass molding, screen printing, and bespoke packaging. Request a pre-production sample (PPS) to inspect the finish of the vessel and the alignment of the labels before authorizing mass production.

Conduct a burn test to check for 'tunneling' (wax remaining on the sides) and ensure the melt pool reaches the edge of the container within 2-4 hours. Monitor the flame height (should not exceed 3 inches) and check for excessive smoking or carbon mushrooming on the wick. Additionally, perform a stability test to ensure the candle does not tip over easily and the container can withstand the heat without cracking.

The biggest risks are melting during transit in high-temperature zones and glass breakage. To mitigate this, use temperature-controlled containers (Reefers) for large shipments during summer months. For packaging, insist on double-walled corrugated boxes and individual cell dividers for glass jars. Ensure the supplier uses palletization with shrink wrap to prevent shifting during sea freight.

Focus on the Total Cost of Ownership (TCO). Negotiate for tiered pricing where the unit cost drops by 10-20% as volume increases. Request FOB (Free On Board) terms to maintain control over your shipping costs. For new partnerships, use secured payment methods and negotiate a 30% deposit / 70% balance payment upon successful third-party pre-shipment inspection.

Candles are often subject to specific HS Codes (typically 3406.00). You must provide a Commercial Invoice, Packing List, and Bill of Lading. Crucially, check for anti-dumping duties; for example, some regions impose high taxes on paraffin candles from specific origins. Ensure all warning labels are printed in the destination country's official language to avoid customs seizures.

Always verify the supplier's Business License and Export License on Made-in-China.com. Look for 'Audited Suppliers' who have undergone on-site inspections by third-party agencies like SGS or Bureau Veritas. Utilize the platform's secured trading services to protect your funds until the goods are verified to meet your specifications.
