Import Tips

• Verify firing temperature exceeds 800°C and material is nonmetallic inorganic per Chapter 69 notes to avoid exclusion

• Provide material composition certificates confirming ceramic properties like low water absorption for technical classification

• Avoid misclassification as machinery parts under Chapter 84; emphasize standalone bearing function in technical docs
