Import Tips

Provide engineering drawings showing boring spindle configuration to distinguish from milling machines under 8459.61

Declare accurate weight and dimensions early; oversized boring mills often trigger additional transport compliance requirements

Avoid pitfalls by certifying no semiconductor-specific adaptations, as those may shift to Chapter 84 statistical notes for wafer processing
