Sinopec paraffin wax

Selecting the right grade depends primarily on the melting point and oil content. For candle making, fully refined wax with a melting point of 58-60°C is ideal for stability and clean burning. For industrial coatings or rubber processing, semi-refined wax or grades with higher oil content may be more economically feasible. Always verify the Sinopec batch number to ensure the product matches the technical data sheet (TDS) for consistency in your production line.

Fully Refined Paraffin Wax undergoes a more rigorous de-oiling process, resulting in an oil content of less than 0.5%, making it odorless and white—perfect for food-grade packaging (FDA compliant) and high-end cosmetics. Semi-Refined Paraffin Wax typically has an oil content between 1.5% and 2%, which is more cost-effective for polishes, matches, and general industrial lubricants where slight odor or color variance is acceptable.

Ensure the supplier provides REACH certification for the EU market and FDA compliance documentation if the wax is used for food contact materials. Since Sinopec is a major global producer, legitimate batches should come with a Certificate of Analysis (COA) and an MSDS (Material Safety Data Sheet). For B2B buyers on Made-in-China.com, look for Audited Suppliers to guarantee that the product meets ISO 9001 quality management standards.

Paraffin wax is sensitive to ambient temperature. It should be stored in a cool, well-ventilated warehouse away from direct sunlight to prevent block sticking (clumping) or deformation. During cross-border shipping, especially through tropical zones, specify reefer containers or ensure the wax is packed in heavy-duty woven bags or cartons with inner plastic liners to maintain structural integrity and prevent contamination.

Counterfeit industrial chemicals are a risk. Always request the original factory analysis report and check the packaging markings; genuine Sinopec wax features specific anti-counterfeiting labels and batch codes. Use the Secured Trading services on Made-in-China.com to ensure payment is only released after a third-party inspection (like SGS or Intertek) confirms the wax grade and purity.

Paraffin wax prices are closely tied to crude oil market fluctuations. Negotiate based on formula-based pricing or lock in rates during market dips. For orders exceeding 20 tons (one 20ft container), aim for a volume discount of 5-10%. Discuss Incoterms clearly; FOB (Free On Board) is often preferred for buyers with their own logistics contracts to better control shipping costs.

The primary risk is moisture and heat damage. Ensure the supplier uses pallets with shrink-wrap to prevent bags from tearing during transshipment. For sea freight, request below-deck stowage to avoid extreme temperature shifts. Ensure all Customs HS Codes (typically 27122000) are correctly declared to avoid delays and ensure compliance with international trade policies regarding petroleum-based products.

Prioritize suppliers with a high 'Trust Score' on Made-in-China.com. Utilize Escrow payment terms or Letters of Credit (L/C) for large-scale transactions. Never send full payment upfront to unverified accounts; a standard 30% deposit and 70% against the Bill of Lading (B/L) is the industry norm for secure cross-border chemical trade.
