Solid paraffin wax

Selecting the correct grade depends primarily on the oil content and melting point. For high-end candle making and food packaging, Fully Refined Paraffin Wax (oil content <0.5%) is essential as it is odorless and stable. For industrial lubricants or lower-grade candles, Semi-Refined Paraffin Wax (oil content 0.5%-1.5%) or Slack Wax (higher oil content) may be more economically feasible. Always match the melting point (typically 54°C to 64°C) to your specific climate and usage scenario to prevent deformation or poor combustion.

Buyers must verify that the product meets ASTM (American Society for Testing and Materials) or ISO standards. Key technical indicators include Penetration (hardness), Color (Saybolt scale), and Flash Point. For food-contact or cosmetic applications, ensure the supplier provides FDA compliance certificates or REACH registration for the European market. Requesting a COA (Certificate of Analysis) for every batch is a non-negotiable requirement for quality assurance.

The melting point determines the thermal stability of the wax. A higher melting point (60°C-62°C) is preferred for products used in tropical climates or for making pillar candles that need to hold their shape. A lower melting point (54°C-56°C) is better for container candles or as an additive in rubber processing to ensure better homogenization and flexibility at lower temperatures.

The biggest risks involve quality inconsistency and fluctuating crude oil prices, which directly impact wax costs. To mitigate this, use Made-in-China.com's audited supplier services to verify the manufacturer's production capacity. Additionally, be aware of anti-dumping duties that some countries impose on Chinese paraffin products; always check your local HS Code (typically 27122000) regulations before finalizing the contract.

Paraffin wax is sensitive to temperature. For cross-border shipping, ensure the wax is packed in 50kg woven bags or 25kg cartons with inner plastic lining to prevent moisture. Avoid shipping in non-insulated containers during peak summer months to prevent caking or melting. Specify in the contract that the cargo must be stored away from direct sunlight and heat sources during transit and port storage.

Since paraffin is a petroleum byproduct, prices are volatile. Negotiate based on volume-based pricing tiers; ordering in Full Container Loads (FCL) can reduce unit costs by 10-15%. For long-term cooperation, suggest a formula-based pricing model linked to global oil benchmarks. Always request pre-shipment inspection (PSI) by third parties like SGS to ensure the weight and quality match the proforma invoice before the final payment is released.
