normal paraffin oil

When purchasing Normal Paraffin (C10-C13 or C14-C17), you must prioritize purity levels (typically >98%) and carbon distribution. Key metrics include the Bromine Index, which indicates the level of unsaturated hydrocarbons (should be <20 mg/100g for high quality), and Sulfur content, which must be below 1 ppm for environmental and catalyst protection. Additionally, verify the distillation range and flash point (typically >70°C) to ensure the product meets your specific industrial application requirements.

Normal Paraffin is a critical raw material primarily used in the production of Linear Alkyl Benzene (LAB) for biodegradable detergents. It is also widely used in chlorinated paraffin production, rolling oils for the aluminum industry, and as a specialized solvent in paints and coatings. For high-end applications, it serves as a base for liquid candles and certain cosmetic formulations, where low odor and high color stability (Saybolt color +30) are mandatory.

Suppliers must provide a comprehensive Material Safety Data Sheet (MSDS/SDS). Since it is a chemical product, ensure compliance with REACH regulations for the European market and TSCA for the US. Look for manufacturers with ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications. For transport, the product must be handled according to IMDG codes for maritime safety, even if classified as non-hazardous, to prevent contamination.

Always request a Pre-Shipment Inspection (PSI) conducted by third-party agencies like SGS or Intertek. The inspection should focus on Gas Chromatography (GC) analysis to confirm the n-paraffin content and carbon chain distribution. It is also vital to check for moisture content (Karl Fischer method), as water contamination can lead to cloudiness and reduced performance in chemical synthesis.

The biggest risks include product contamination during transit and price volatility of petroleum-based feedstocks. Mitigate these by insisting on dedicated ISO tanks or epoxy-lined drums to prevent rust and cross-contamination. To manage price risks, consider formula-based pricing linked to global benchmarks (like ICIS or Platts) or securing fixed-price contracts for short-term quarterly volumes.

For liquid chemicals, FOB (Free On Board) or CIF (Cost, Insurance, and Freight) are standard. However, for large volumes, CFR (Cost and Freight) is often preferred by buyers who have established relationships with specialized chemical shippers. Ensure the supplier provides a Clean Bill of Lading and a Certificate of Analysis (COA) that matches the specific batch number loaded onto the vessel.

Utilize secure payment methods such as Letter of Credit (L/C at sight) for large-scale industrial orders, which ensures payment is only released upon presentation of valid shipping documents. For sourcing through Made-in-China.com, leverage their Audit Reports to verify the supplier's production capacity and legal existence, reducing the risk of dealing with non-existent entities.

Focus on volume-based incentives; manufacturers often offer significant discounts for full shiploads or annual off-take agreements. Discuss payment flexibility, such as a 30% deposit with the 70% balance against the BL copy. Additionally, negotiate for extended storage periods at the port of origin to allow for more flexible shipping schedules.
