Import Tips & Compliance
• Provide lab analysis confirming <70% iron content to avoid earth color exclusion in Chapter 28
• Use photos and measurements to prove 'merely cut by sawing' status; grinding disqualifies
• Check for dolomite content; high levels may require ramming mix classification under 3816
