Import Tips
• Submit detailed particle size distribution and drop shatter test results conducted per ASTM D 3038 standards
• Declare exact moisture content and ash levels, as foundry coke typically requires low impurities for compliance
• Avoid common pitfall of mixing sizes; segregate lots to ensure all material meets the 100-mm retention threshold
