Import Tips
• Ensure the product is presented as a powder or oxide, not as a sintered ceramic article, which would fall under Chapter 69
• Provide a certificate of analysis confirming the chemical composition to support classification under 2825.60.00
• Verify whether the stabilizer content affects the 'chemically defined' status; mixtures may require additional documentation
