Wholesale liquid paraffin oil

Buyers must distinguish between Industrial Grade, Cosmetic Grade, and Pharmaceutical Grade (USP/BP/EP). Key metrics include Kinematic Viscosity (typically measured at 40°C), Flash Point (should be >180°C for safety), and Purity levels. For high-end applications, ensure the oil is colorless, odorless, and tasteless, with a Saybolt color rating of +30.

Depending on the end-use, products must adhere to REACH (EU) for chemical safety, FDA (US) for food-grade or medical applications, and ISO 9001 for manufacturing quality. For pharmaceutical use, a Certificate of Analysis (COA) confirming compliance with USP (United States Pharmacopeia) or BP (British Pharmacopeia) is non-negotiable.

Light Liquid Paraffin (LLP) is preferred for cosmetics, hair oils, and ointments due to its easy absorption and spreadability. Heavy Liquid Paraffin (HLP) is better suited for industrial lubricants, plasticizers, and internal medical lubricants where a higher protective barrier or lubrication film is required.

Liquid paraffin is chemically stable but should be stored in epoxy-lined steel drums or HDPE containers to prevent contamination. It must be kept in a cool, well-ventilated area away from strong oxidizing agents. Ensure the supplier provides a Material Safety Data Sheet (MSDS) detailing the shelf life, which is typically 24 to 36 months under optimal conditions.

The biggest risks are grade substitution (shipping industrial grade as cosmetic grade) and contamination during transit. To mitigate this, use third-party inspection services (like SGS or Intertek) to test samples directly from the shipping containers before departure. Always verify the HS Code (typically 2710.19) to ensure correct duty calculations.

Liquid paraffin prices are tied to crude oil market fluctuations. Negotiate for formula-based pricing if signing long-term contracts. For Wholesale MOQs, standard units are 20ft containers (approx. 80 drums). Request a tiered pricing structure where a 5-10% discount is applied for orders exceeding 3 containers.

While liquid paraffin is generally classified as non-hazardous for transport (Non-DG), you must confirm this with the supplier's Non-Hazardous Cargo Declaration. For large volumes, ISO Tanks are more cost-effective than drums. Ensure the bill of lading specifies 'Keep away from heat' to prevent expansion and leakage during tropical transit routes.

Utilize Secured Trading Services provided by reputable platforms like Made-in-China.com to protect your payment until delivery is confirmed. Prioritize Audited Suppliers who have undergone on-site factory inspections. For initial large orders, consider using a Letter of Credit (L/C) to ensure the supplier meets all documentation and quality benchmarks before funds are released.
