Import Tips

• Include technical datasheets confirming refractoriness under load (RUL) at 1400°C+ to support classification

• Label shipments clearly as 'refractory constructional goods' to prevent confusion with ornamental ceramics

• Check for anti-dumping duties on specific origins; obtain scope rulings if composition borders on 6902.20
