Import Tips

• Verify firing temperature exceeds 800°C with manufacturer certificates to confirm Chapter 69 eligibility; unfired clay products fall outside this chapter

• Provide detailed composition reports showing clay as primary ingredient (>50%) to avoid misclassification under siliceous earth headings

• Include end-use documentation proving refractory application to distinguish from building materials in Chapter 68
