Import Tips
• Classify breaker plates as parts of hammermills under 8474.90.00; the CBSA may request the mill model and plate specifications
• Ensure the plates are described as impact-resistant and perforated for mineral grinding, not as general-purpose screens
• If the plates are made of special alloys, provide the material certificate to support the classification
