Petroleum jelly manufacturers

Petroleum Jelly is categorized into three primary grades: Pharmacopoeia Grade (USP/BP/EP), Cosmetic Grade, and Industrial Grade. For B2B buyers in the medical or skincare sector, it is mandatory to source USP (U.S. Pharmacopeia) or BP (British Pharmacopeia) grade to ensure the product is highly refined, non-comedogenic, and free from polycyclic aromatic hydrocarbons (PAHs). Cosmetic grade is suitable for general lotions, while industrial grade is used for rust prevention and cable filling.

When reviewing a Certificate of Analysis (COA), prioritize the Drop Melting Point (typically 45°C - 60°C), Cone Penetration (consistency), and Kinematic Viscosity. For high-quality applications, ensure the Color Value is 'White' (Saybolt color +30) rather than 'Yellow' to indicate a higher level of refinement. Additionally, verify that the Polycyclic Aromatic Hydrocarbons (PAHs) content meets international safety thresholds to avoid toxicity.

Suppliers must provide ISO 22716 (Good Manufacturing Practices for Cosmetics) or GMP (Good Manufacturing Practice) certifications. If exporting to the EU, REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) compliance is a prerequisite. For the US market, ensure the manufacturer is FDA registered if the product is marketed as an over-the-counter (OTC) skin protectant.

Petroleum Jelly is highly stable but can be contaminated by external odors or heat. For bulk procurement, new steel drums (170kg-180kg) with internal coatings are the industry standard to prevent oxidation. For retail-ready products, ensure the PE or PP jars are BPA-free and feature induction foil seals to prevent leakage during high-temperature transit in tropical shipping routes.

The most significant risk is adulteration or under-refinement, where industrial-grade jelly is passed off as cosmetic grade. This can lead to skin irritation and legal liability. To mitigate this, always request a pre-shipment inspection (PSI) by third parties like SGS or Intertek to verify that the batch matches the approved sample's purity and odor profile.

Petroleum Jelly prices are closely tied to crude oil market fluctuations. It is advisable to negotiate formula-based pricing for long-term contracts. For MOQs, while large refineries prefer Full Container Loads (FCL), you can negotiate a trial order of 1-5 tons by emphasizing long-term partnership potential. Always check if the supplier is a Gold Member on Made-in-China.com to ensure they have a verified production capacity.

Although Petroleum Jelly is generally classified as non-hazardous (Non-DG) for sea freight, you must obtain a Material Safety Data Sheet (MSDS) and a Non-Hazardous Chemical Certificate to avoid customs delays. During summer months, ensure the containers are stowed 'below deck' or away from heat sources to prevent the product from reaching its melting point and leaking.

Utilize secured payment terms such as Letter of Credit (L/C) for large volumes or Escrow-based payment services provided by reputable B2B platforms like Made-in-China.com. Avoid 100% upfront T/T payments; a standard 30% deposit and 70% against the Bill of Lading (B/L) copy is the professional benchmark for the chemical industry.
