Base oil sn 150

Base Oil SN 150 is a Group I light-grade base oil primarily used for lubricants. You must verify the Viscosity Index (typically 90-105), Flash Point (minimum 190°C), and Pour Point (maximum -6°C to -12°C). Additionally, ensure the Sulfur content meets your specific application requirements, as SN 150 is characterized by its solvent-refined nature and high solubility.

Request a Certificate of Analysis (COA) for every batch. Key indicators of quality include Color (ASTM D1500, usually <1.5) and Appearance (Clear and Bright). For high-volume B2B orders, it is highly recommended to engage third-party inspection services like SGS or Intertek to perform loading inspections and verify that the chemical properties align with the provided technical data sheets.

SN 150 is highly versatile. It is commonly used as a blending component for passenger car motor oils (PCMO), industrial hydraulic oils, and transformer oils. It also serves as a process oil in the production of rubber, adhesives, and greases due to its excellent solvency and compatibility with additives.

Suppliers should ideally be ISO 9001 certified for quality management. Since base oils are chemical products, ensure the supplier provides a comprehensive Material Safety Data Sheet (MSDS) and complies with REACH regulations if you are importing into the European Union. For international trade, verify that the packaging meets IMDG (International Maritime Dangerous Goods) standards if applicable.

The most significant risks include quality inconsistency between samples and bulk cargo and price volatility in the petroleum market. To mitigate these, use Letter of Credit (L/C) as a payment method to ensure funds are only released upon presentation of valid shipping and inspection documents. Always source from verified manufacturers on reputable platforms like Made-in-China.com to ensure supplier legitimacy.

Base oil prices are often linked to ICIS or Argus benchmarks. Negotiate a pricing formula based on these indices rather than a fixed price for long-term contracts. Discuss MOQ (Minimum Order Quantity); while bulk vessels offer the best rates, Flexitanks or ISO Tanks are more cost-effective for medium-sized buyers as they reduce cleaning and return logistics costs.

Ensure the supplier is experienced in Flexitank loading to prevent leakages during transit. Confirm the Incoterms clearly; CIF (Cost, Insurance, and Freight) is common, but FOB (Free on Board) allows the buyer more control over the shipping line and transit time. Always verify the vessel's age and insurance coverage to prevent maritime delays or losses.

Utilize the Audit Reports available on Made-in-China.com to check the supplier's production capacity and export history. Look for 'Diamond' or 'Gold' member status, which indicates a higher level of verification. Requesting a factory video tour or a small trial order before committing to a full vessel or container load is a standard industry practice to validate operational scale.
