Import Tips
• Cobalt content documentation essential - distinguishes from standard M2/M35 for proper high-speed steel verification
• Check for 'universal mill plate' characteristics (note b) which might affect classification if patterned
• Ensure no chemical surface treatments (phosphating, etc.) as these constitute 'further worked'
