Import Tips
• Verify the slag originates from iron or steel manufacture via supplier certification to avoid misclassification as other wastes
• Ensure particle size and granulation meet 'slag sand' specs; test for metallic content per statistical notes
• Obtain environmental clearances as slag may be regulated for heavy metals; declare assay quantity accurately
