Import Tips
• Verify cutting part composition via material certificates to confirm over 0.2% Cr/Mo/W; common pitfall is misclassification as non-alloyed bits
• Provide end-use documentation for mining applications to avoid reclassification
• Label as 'percussion type' to distinguish from rotary bits
