Import Tips

• Verify firing temperature exceeds 800°C and document thermal conductivity specs to confirm heat insulating classification per Chapter 69 notes

• Include test reports for water absorption and material composition to avoid reclassification as non-ceramic under heading 6804

• Check building code compliance certificates as common pitfalls include missing structural load-bearing documentation
