Import Tips & Compliance
• Verify water absorption ≤0.5% via ASTM C373 test to confirm porcelain classification; provide lab certificates at entry
• Include manufacturer specs proving post-shaping firing above 800°C to avoid exclusion from Chapter 69
• Declare as individual flush tank, not part of complete water closet set, to prevent misclassification under 6910.10.00.10
