Yellow petroleum jelly manufacturers

Yellow Petroleum Jelly is categorized primarily by its purity and application. For industrial use, ensure it meets ASTM D937 for cone penetration and ASTM D127 for drop melting point. If the product is intended for topical applications, it must comply with Pharmacopoeia standards (USP, BP, or EP). Buyers should verify the Polycyclic Aromatic Hydrocarbons (PAHs) content to ensure it meets safety regulations, especially for cosmetic or medicinal formulations.

The most critical specifications include Melting Point (typically 45°C to 60°C), Kinematic Viscosity, and Consistency (Cone Penetration). For cosmetic use, color stability and odorless properties are paramount. For industrial lubricants or rust prevention, the moisture content (should be <0.1%) and acid value are more important to prevent corrosion of metal parts.

Request a Certificate of Analysis (COA) for every batch. A high-quality Yellow Petroleum Jelly should show excellent oxidation stability, meaning it won't turn rancid or change color significantly over time. The typical shelf life is 3 to 5 years when stored in a cool, dry place away from direct sunlight. Ensure the supplier provides UV stability test results if the product will be used in transparent packaging.

It is widely used as a lubricant in the leather industry, a base for industrial salves, and a rust preventive coating for machinery. In the chemical sector, it serves as a plasticizer in rubber processing and an anti-foaming agent. It is also a key ingredient in veterinary ointments and lower-cost cosmetic balms where the yellow tint is acceptable or desired.

Since Petroleum Jelly is a chemical product, you must obtain a current Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS). For sea freight, a Non-Dangerous Goods Certificate is often required to prove the cargo is non-hazardous. Ensure the supplier provides a Commercial Invoice, Packing List, and Bill of Lading that accurately reflect the HS Code (typically 2712.10) to avoid customs delays.

Always use secure payment methods such as Letters of Credit (L/C) or escrow-based services. On Made-in-China.com, look for Audited Suppliers who have undergone third-party verification by agencies like SGS or TÜV Rheinland. It is highly recommended to request a pre-shipment inspection (PSI) to verify that the color and consistency of the bulk order match the approved sample.

Yellow Petroleum Jelly is usually packed in 170kg-180kg steel drums or ISO tanks for large volumes. Ensure the drums are new and internally coated to prevent contamination from rust. During transit through tropical regions, ensure the container is stored away from heat sources on the vessel to prevent the product from melting and leaking, which could lead to significant insurance claims.

Be aware of anti-dumping duties or specific environmental taxes on petroleum-derived products in your country. Check the Rules of Origin to see if your country has a Free Trade Agreement (FTA) with the supplier's country, which could allow for reduced or zero import tariffs upon presentation of a Certificate of Origin (Form E or Form F).
