Import Tips

• Verify material composition (e.g

• steel alloy) and provide engineering drawings to confirm classification as 'other gearing' not qualifying for specific exclusions

• Include detailed invoices specifying gear module, pitch, and application to avoid misclassification as parts of specific machines

• Ensure compliance with ASME standards for gear tolerances to prevent customs holds on quality grounds
