Normal paraffin

When evaluating Normal Paraffin (n-paraffin), the most critical factor is the carbon chain distribution (typically C10-C13 for LAB production or C14-C17 for chlorinated paraffin). You must verify the purity level (minimum 98% n-alkane content), as high aromatics or sulfur content can negatively impact downstream chemical reactions. Additionally, check the distillation range, flash point (typically >70°C for safety), and Bromine Index to ensure low unsaturation levels.

Suppliers should provide a Certificate of Analysis (COA) for every batch. For cross-border trade, ensure compliance with REACH regulations if exporting to Europe, and verify that the manufacturer follows ISO 9001 for quality management and ISO 14001 for environmental standards. Since it is a chemical product, a comprehensive Material Safety Data Sheet (MSDS) in English is mandatory for international shipping and customs clearance.

Normal Paraffin is a versatile feedstock. If you are in the detergent industry, you require high-purity C10-C13 for Linear Alkyl Benzene (LAB) production. For metalworking fluids or PVC plasticizers, C14-C17 grades are more common. Understanding the end-use is vital because impurities like moisture or heavy metals can poison catalysts in industrial processes, so sourcing from a supplier with dedicated storage tanks to prevent cross-contamination is essential.

Pricing is heavily influenced by crude oil market fluctuations. To optimize costs, consider long-term off-take agreements rather than spot-market purchases. Evaluate the Total Cost of Ownership (TCO) by factoring in the logistics of liquid bulk transport (ISO tanks vs. Flexitanks). Sourcing from integrated refineries often provides a 10-15% price advantage over secondary distributors due to the elimination of middleman margins.

The primary risks include product contamination during transit and regulatory non-compliance. To mitigate these, use third-party inspection services (like SGS or Intertek) to perform loading surveys and laboratory testing before the vessel departs. Always use secure payment terms such as Letter of Credit (L/C) or escrow services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon verification of shipping documents.

Normal Paraffin is generally classified as a non-hazardous liquid for transport if the flash point is high, but it still requires careful handling. ISO Tanks are the gold standard for maintaining product integrity, while Flexitanks offer a more cost-effective solution for 20ft containers. Ensure the supplier uses dedicated pumps and hoses to avoid contamination and confirm that the packaging meets UN standards if the specific grade is classified as flammable.

Focus on volume-based pricing tiers and payment flexibility. Request a trial order of one ISO tank to verify quality before committing to large annual volumes. Suppliers on Made-in-China.com are often willing to offer discounts of 3-5% for 100% T/T at sight or better lead times for repeat buyers. Clearly define the Incoterms (FOB vs. CIF) in the contract to avoid hidden freight or insurance costs.
