Petroleum coke

Buyers must prioritize the Sulfur Content, which typically ranges from Low Sulfur (<1%) for anodes to High Sulfur (>3%) for fuel. Other critical metrics include Fixed Carbon (ideally >85-90%), Volatile Matter (8-12%), Ash Content (<0.5% for high quality), and Hardgrove Grindability Index (HGI) to ensure compatibility with industrial kilns or furnaces.

Green Petroleum Coke is the raw output from the coker unit, primarily used as fuel in cement kilns and power plants. Calcined Petroleum Coke (CPC) has undergone heat treatment to remove moisture and volatiles, resulting in high electrical conductivity; it is essential for aluminum smelting (anodes) and steel production (recarburizers).

Due to its high carbon and sulfur density, suppliers should provide Material Safety Data Sheets (MSDS). International trade requires compliance with ISO 12985 for carbonaceous materials. Buyers in the EU must ensure REACH registration, while US-bound shipments must align with EPA emission standards regarding sulfur dioxide (SO2) output during combustion.

Always mandate a Pre-shipment Inspection (PSI) by independent third parties like SGS or Intertek. The analysis should focus on moisture levels, as excessive water increases weight and shipping costs while reducing heating value. Request a Certificate of Analysis (COA) for every batch to ensure consistency in calorific value (typically >7,500 - 8,500 kcal/kg).

The most significant risks include quality substitution (mixing high-sulfur with low-sulfur coke) and weight discrepancies. To mitigate this, use Draft Surveys at both loading and discharge ports. Ensure the contract specifies price adjustments or penalties if the sulfur or ash content exceeds the agreed-upon thresholds.

Petcoke pricing is often tied to global coal indices or crude oil benchmarks. Negotiate based on long-term off-take agreements rather than spot purchases to secure stable pricing. For large volumes, aim for FOB (Free On Board) terms to maintain control over chartering vessels, which can significantly impact the Total Landed Cost.

Utilize Irrevocable Letters of Credit (L/C) at sight or Bank Guarantees. Avoid 100% advance payments. For new suppliers found on Made-in-China.com, prioritize Audited Suppliers who have undergone comprehensive on-site verification of their production capacity and financial standing.

Petcoke is a bulk commodity usually shipped via Handymax or Panamax vessels. It is prone to self-heating and dust explosions; therefore, the carrier must comply with the IMSBC Code (International Maritime Solid Bulk Cargoes). Ensure the moisture content is kept within the Transportable Moisture Limit (TML) to prevent liquefaction during sea transit.
