Import Tips
• Provide metallurgical analysis reports proving tungsten content to justify alloyed classification
• Avoid bundling with non-tool parts; ship as individual bits to prevent set classification issues
• Check for IADC code labeling, common for tricone bits, to support rock drilling end-use
