3. Operational Transparency and Process Control

Top-tier suppliers disclose details about their coal blending processes, coking oven types (e.g., stamp charging vs. conventional), and hourly sampling protocols. Greater transparency correlates with tighter quality consistency. For instance, Hebei Gangan Coke Trade Co., Ltd. emphasizes process traceability and uses automated monitoring systems during carbonization.

4. Logistics and Export Readiness

Assess the supplier’s experience with international shipping, Incoterms familiarity, and documentation accuracy. Look for digital tracking capabilities, customs clearance support, and partnerships with reputable freight forwarders. Proximity to major ports (like Qingdao or Tianjin) reduces transit time and demurrage risks.
