High temperature grease price

When sourcing high temperature grease, the most critical factor is the Dropping Point, which should be at least 50°C higher than your maximum operating temperature. You must also verify the Base Oil Viscosity (typically ISO VG 220 or higher for heavy loads) and the Thickener Type. For extreme heat, Lithium Complex, Calcium Sulfonate, or Polyurea thickeners are preferred over standard lithium. Additionally, ensure the product meets NLGI Grade 2 consistency for general industrial applications.

Price is heavily influenced by the environment. For food-processing machinery, you must require NSF H1 Certification, which carries a premium. For heavy mining or construction equipment, the grease must contain Extreme Pressure (EP) additives like Molybdenum Disulfide (Moly). If the application involves water washout (e.g., steel mills), prioritize Calcium Sulfonate bases due to their inherent water resistance and anti-corrosion properties.

To ensure safety and quality, confirm that the supplier complies with ISO 9001 for manufacturing consistency and ISO 14001 for environmental management. For international trade, request the Material Safety Data Sheet (MSDS) and Technical Data Sheet (TDS). If exporting to Europe, ensure the grease is REACH compliant to avoid customs delays regarding chemical substances.

Request third-party lab results for the Four-Ball Wear Test (ASTM D2266) and the Oil Separation Test (ASTM D1742). A high-quality grease should show a wear scar diameter of less than 0.5mm. I recommend sourcing from reputable manufacturers on Made-in-China.com who can provide batch-specific Certificates of Analysis (COA) to guarantee that the delivered product matches the sample performance.

The main risks include leakage during transit and regulatory non-compliance. Ensure the supplier uses UN-certified steel drums or high-density plastic pails with airtight seals. Because grease is a chemical, it may be flagged as 'Dangerous Goods' (DG); always confirm the HS Code (usually 271019) with your customs broker to determine if special IMO Class packaging is required for sea freight.

Negotiate based on Total Volume Commitment rather than single orders. Suppliers on Made-in-China.com often offer 15-25% discounts for 20ft container loads. You can also reduce costs by opting for standardized packaging (18kg pails or 180kg drums) instead of customized small cartridges, which carry higher labor and material overheads.

Use Trade Assurance or Escrow services to protect your payment until the goods are shipped. For shipping, FOB (Free On Board) is recommended so you can control the freight forwarder and ensure they have experience handling liquid or semi-solid chemicals. Always insist on a Pre-shipment Inspection (PSI) to verify the production date, as grease has a shelf life (typically 2-3 years).
