Import Tips
• Verify compressive strength certifications to meet building codes like ASTM C90 for hollow concrete blocks
• Ensure documentation includes material composition to avoid misclassification as artificial stone products
• Inspect for reinforcement; unreinforced blocks stay in 6810.11.00, but reinforced may shift to other subheadings
