Import Tips
• Verify compatibility with specific Rockwell scale (A, B, C) for correct classification and avoid misdeclaration
• Provide manufacturer specs confirming use solely with 9024.10 hardness testers to prevent reclassification under general parts headings
• Include calibration certificates; common pitfall is importing without proof of metrological standards compliance
