Import Tips
• Classify as a catalytic preparation if the washcoat is essential for the catalytic function; if it is merely a support, other headings may apply
• Provide technical specifications showing the oxygen storage capacity and catalytic role
• Ensure the product is not part of a complete catalytic converter, which would fall under chapter 84
