Import Tips
• Include technical specifications showing backup roll diameter (>1m typically) and material hardness to distinguish from work rolls
• Ensure invoices specify 'for rolling mills' to prevent reclassification as general machinery parts
• Comply with ISO 9001 certification for quality assurance in metallurgical applications
