Lubricating spray

Buyers should prioritize viscosity index, temperature stability, and load-carrying capacity. For high-performance applications, ensure the spray contains additives like PTFE (Polytetrafluoroethylene) or Molybdenum Disulfide (MoS2) for reduced friction. Additionally, verify the dielectric strength if the product is intended for use near electrical components to prevent short circuits.

As lubricating sprays are often classified as hazardous materials, they must have a valid MSDS (Material Safety Data Sheet) or SDS (Safety Data Sheet). For the EU market, REACH and RoHS compliance is essential. If the product is used in food processing areas, it must hold NSF H1 or H2 certification to ensure safety in case of incidental food contact.

The aerosol valve design and propellant type (such as CO2 or LPG) significantly impact the spray pattern and pressure consistency. Request information on the 360-degree spray capability, which allows the canister to function upside down, and the inclusion of a dual-action straw system for both broad application and precision targeting in tight mechanical gaps.

Analyze the active ingredient concentration versus propellant ratio; cheaper sprays often contain more gas and less lubricant, leading to a higher cost-per-use. Evaluate the shelf life, which should typically be 24 to 36 months, to minimize waste in long-term inventory holding. Bulk discounts on Made-in-China.com typically trigger at 1,000+ units, potentially reducing unit costs by 15-25%.

Lubricating sprays are categorized as Class 2.1 (Flammable Gas) or Class 2.2 (Non-flammable Gas) under the IMDG Code. You must ensure the supplier provides UN-certified packaging and a Dangerous Goods (DG) Declaration. Shipping via air is highly restricted and expensive; sea freight is the standard method, requiring specialized containers and stowage away from heat sources.

Utilize Secured Trading Services on Made-in-China.com to protect your payment until the goods are shipped. Always request a pre-shipment inspection (PSI) by a third party like SGS or Intertek to verify the chemical composition and pressure levels of the canisters before they leave the factory.

Focus negotiations on formulation customization and private labeling (OEM). If you are ordering high volumes, negotiate for free spare nozzles or customized outer carton reinforcement to prevent leakage during transit. Ask for a tiered pricing structure based on the fluctuating cost of raw materials like base oils and tinplate for the cans.

Check for Anti-Dumping Duties (ADD) in your specific country regarding aerosol cans or specific chemical lubricants. Ensure the HS Code (typically 3403 or 2710) is correctly declared to avoid customs delays and ensure the correct tariff rates are applied. Failure to provide a Certificate of Origin may result in higher duty payments in certain trade zones.
