Used diesel

When purchasing recycled or used diesel, you must prioritize viscosity, flash point, and sulfur content. Ensure the fuel meets ASTM D975 (for diesel fuel oils) or ISO 8217 standards if intended for marine use. Specifically, check the Cetane Index to ensure combustion efficiency and the Cold Filter Plugging Point (CFPP) to prevent engine stalling in colder climates. A water and sediment content of less than 0.05% is essential to prevent fuel system corrosion.

Buyers should mandate a Certificate of Analysis (COA) for every batch. It is highly recommended to engage a third-party inspection agency like SGS or Intertek to perform 'bottom-middle-top' sampling from storage tanks. Focus on density at 15°C and calorific value to ensure the energy output meets your operational requirements. For long-term contracts, verify the supplier's filtration and distillation technology to ensure the removal of heavy metal contaminants.

The product must comply with the Basel Convention if it is classified as hazardous waste, or local environmental regulations like REACH (EU) or EPA standards (USA) if sold as a fuel product. Ensure the supplier provides a comprehensive Material Safety Data Sheet (MSDS). For cross-border trade, the Harmonized System (HS) Code (typically under Chapter 27) must be accurately declared to avoid customs seizures related to environmental protection laws.

The fuel industry is prone to non-performance and 'ghost' supplier risks. Never pay 100% upfront via T/T. Instead, utilize Documentary Letters of Credit (L/C) or Escrow services where payment is only released upon the presentation of a Bill of Lading (B/L) and a Quality/Quantity Inspection Report issued at the loading port. On platforms like Made-in-China.com, prioritize Audited Suppliers who have undergone rigorous on-site verification.

For bulk liquid cargo, FOB (Free On Board) or CIF (Cost, Insurance, and Freight) are standard. However, for used diesel, CIF is often preferred for buyers to ensure the seller handles the complex logistics of hazardous material transport. Ensure the contract specifies allowable shrinkage/loss rates (typically 0.3% to 0.5%) during transit and clearly defines the Point of Title Transfer.

Used diesel is classified as Class 3 Flammable Liquid (UN1202). Shipping requires ISO Tanks or specialized chemical tankers that meet international maritime dangerous goods (IMDG) codes. You must verify that the destination port has the necessary infrastructure and licenses to receive and store recycled petroleum products, as some ports have strict 'Green' policies against the import of used oils.
