Import Tips
• Ensure the main shaft assembly is described as a part of a cone or gyratory crusher under 8474.90.00; the CBSA may require engineering drawings to confirm its function
• Verify that the shaft is not a general-purpose transmission shaft, which would fall under a different heading
• If the assembly includes bearings, confirm whether they are integral or separate for classification purposes
