Import Tips
• Ensure the bushes are fired after shaping, as Macor is a glass-ceramic that must meet Chapter 69's firing requirement
• Provide documentation on the prototype lab or chemical fixture application to justify classification
• Note that post-firing machining does not disqualify the product from Chapter 69
