Import Tips

Verify chemical composition certificate showing >50% Al2O3 or SiO2 to confirm classification under 6902.20

Provide firing temperature documentation (>800°C) to distinguish from non-fired ceramic articles excluded from Chapter 69

Avoid common pitfalls like importing unshaped mixes, which fall under Chapter 28 chemicals rather than finished refractory goods
