Import Tips
• Verify chemical composition certification for chromium content (>0.2%) to confirm classification and avoid reclassification to lower-duty subheadings
• Provide manufacturer specs and end-use documentation to customs, as rock drilling tools require proof of non-machine-tool primary use
